In other words, it is possible to compare the costs (electricity charges and fuel costs) required to travel the same distance with moving objects with different power sources. Therefore, according to the presentation system 18, it is possible to evaluate the cost-effectiveness of the mobile body (vehicle 3) whose power source is electric power.

1.2 Details 1.2.1 Charge control system As shown in FIG. 2, the charge control system 10 is introduced in the house H1 which is a detached house. The charge control system 10 is used to charge the storage battery 31 of the vehicle 3 parked in the garage attached to the house H1. The storage battery 31 is used to store electric power used as a power source for the vehicle 3.

The vehicle 3 is a mobile body whose power source is electric power. The vehicle 3 converts the electric power (electrical energy) output from the storage battery 31 into mechanical energy (driving force) by an electric motor or the like, and moves using this mechanical energy. In this type of mobile body, the electric energy stored in the storage battery 31 is consumed as the moving body moves. Therefore, in order to continuously use the moving body, it is necessary to charge the storage battery 31 at any time. It becomes. The vehicle 3 is an electric vehicle having at least a storage battery 31 and traveling by using the electric energy stored in the storage battery 31. The "electric vehicle" as used in the present disclosure means a vehicle including at least an electric motor as a prime mover. That is, the "electric vehicle" may also include an internal combustion engine as a prime mover. Examples of the electric vehicle include an electric vehicle that travels by the output of the electric motor, or a plug-in hybrid vehicle that travels by combining the output of the engine (internal combustion engine) and the output of the electric motor. Further, the electric vehicle may be a senior car, a two-wheeled vehicle (electric motorcycle), a tricycle, an electric bicycle, or the like. The vehicle 3 further has a charging circuit 32 in addition to the storage battery 31. The charging circuit 32 is a circuit that receives power from the charging facility 2 and executes charging of the storage battery 31.

As shown in FIGS. 1 and 2, the charge control system 10 includes a device control device 1 and a charge system 2. In other words, the device control device 1 constitutes the charge control system 10 together with the charge system 2. In the present embodiment, the device control device 1 and the charging system 2 cooperate with each other to realize the function as the charging control system 10.

Therefore, the device control device 1 and the charging system 2 are configured to be able to communicate with each other. In the present disclosure, "communicable" means that information can be exchanged directly or indirectly via a network, a repeater, or the like by an appropriate communication method of wired communication or wireless communication. That is, the device control device 1 and the charging system 2 can exchange information with each other. In the present embodiment, the device control device 1 and the charging system 2 can communicate with each other in both directions, and information is transmitted from the device control device 1 to the charging system 2 and from the charging system 2 to the device control device 1. It is possible to send both information.

The device control device 1 is installed inside the house H1. The device control device 1 is a device that controls various devices (including equipment) to be controlled, including at least the charging system 2. The device control device 1 outputs a "charging command" for instructing the start of charging and a "stop command" for instructing the stop of charging to at least the charging system 2, thereby causing the charging system 2 to output. Controls the charging of the storage battery 31 by the charging system 2.

The charging system 2 is installed outside (outdoors) of the house H1 by being attached to an outer wall or a support column of the house H1. The charging system 2 has a connecting portion 26 that can be connected to the storage battery 31, and a charging cable 8 is electrically connected to the connecting portion 26. The charging cable 8 has a plug 81 at its tip. The plug 81 is removably connected to the vehicle 3. Since the charging system 2 is electrically connected to the vehicle 3 via the charging cable 8 with the plug 81 connected to the vehicle 3, it is possible to supply electric power to the vehicle 3 via the charging cable 8. , The storage battery 31 can be charged.

In the charge control system 10, the device control device 1 can control various devices (including facilities) other than the charging facility 2. Specifically, as shown in FIG. 2, the device control device 1 includes a distribution board 61 installed in the house H1, a load 62 composed of electric devices such as lighting equipment and air conditioning equipment, and a photovoltaic power generation facility 7. It is configured to be able to communicate with. Here, the device control device 1 is connected to the router 64 and communicates directly with the distribution board 61, the load 62, and the like, or indirectly via the router 64. As a result, the device control device 1 acquires information on the state of the load 62 (for example, lighting / extinguishing in the case of a lighting fixture) from the load 62, and transmits information for controlling the load 62 to the load 62. It is possible to do it.

The charging system 2 is electrically connected to the distribution board 61, and the load 62 is further electrically connected to the distribution board 61. Further, a power system 63 such as a commercial power source and a photovoltaic power generation facility 7 are further electrically connected to the distribution board 61. As a result, the distribution board 61 can supply the electric power supplied from the electric power system 63 or the photovoltaic power generation facility 7 to the charging system 2 and other loads 62.

The photovoltaic power generation facility 7 includes a power storage device 72 and a power conditioner 73 in addition to the solar cell 71. The solar cell 71 outputs electric power corresponding to the amount of solar radiation to the solar cell 71 as generated electric power. The power storage device 72 is configured to be able to store the generated power of the solar cell 71 and the power supplied from the power system 63. The power storage device 72 outputs the electric power (electrical energy) stored in the power storage device 72 as discharge power. The power conditioner 73 converts the generated power of the solar cell 71 or the discharge power of the power storage device 72 into AC power and outputs the power to the distribution board 61. As a result, the electric power output from the photovoltaic power generation facility 7 can be supplied to the charging system 2 and other loads 62 via the distribution board 61.

The distribution board 61 uses a current sensor to detect the power supplied from the power system 63, the power supplied from the photovoltaic power generation facility 7, and the power consumption of the load 62 and the like (including the charging facility 2 and the photovoltaic power generation facility 7). It has a function to measure by. Therefore, the device control device 1 distributes information on the power supplied from the power system 63, the power supplied from the solar power generation facility 7, the power consumption of the load 62, and the like by communicating with the distribution board 61. It can be obtained from the board 61 as appropriate.

Further, the device control device 1 is connected to a network 65 such as the Internet via a router 64. As a result, the device control device 1 can communicate with the information terminal 41 via the router 64, and can communicate with the information terminal 42 via the router 64 and the network 65. The information terminal 41 is a terminal such as a smartphone or tablet terminal inside the house H1, and the information terminal 42 is a terminal such as a smartphone or tablet terminal outside the house H1. Hereinafter, when the information terminals 41 and 42 are not particularly distinguished, these information terminals 41 and 42 are collectively referred to simply as "information terminal 4". A server 5 is further connected to the network 65. As a result, the device control device 1 can communicate with the information terminal 4 and the server 5.

1.2.2 Device control device The device control device 1 constitutes the charge control system 10 together with the charge system 2, and is a part of the charge control system 10.

It has a presentation system 18.

The device control device 1 can be realized by a computer system including one or more memories and one or more processors. That is, each unit (setting unit 12, control unit 13, display control unit 14, and presentation system 18) of the device control device 1 is executed by one or more processors executing a program recorded in one or more memories of the computer system. ) Function is realized. The program may be pre-recorded in a memory, provided through a telecommunication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

The first communication unit 11 communicates with the charging system 2 directly or indirectly via a network or a repeater or the like. As a communication method between the first communication unit 11 and the charging system 2, an appropriate communication method of wireless communication or wired communication is adopted. In the present embodiment, as an example, the communication method between the first communication unit 11 and the charging system 2 is wired communication conforming to a communication standard such as a wired LAN (Local Area Network). The communication protocol in the communication between the first communication unit 11 and the charging system 2 is, for example, Ethernet (registered trademark), ECHONET Lite (registered trademark), or the like.

The setting unit 12 has a function of setting a charging schedule. The charging schedule is a schedule that defines the operating state for each time zone. The charging schedule set by the setting unit 12 is stored in the memory of the device control device 1, the server 5, or the like. The setting unit 12 can select the operating state in at least a part of the charging schedule from a plurality of states. The plurality of states referred to here include a charged state and a stopped state. The charging state is a state in which the storage battery 31 is charged. The stopped state is a state in which the storage battery 31 is not charged.

Further, the setting unit 12 sets the charging schedule based on the operation signal from the input interface 15 that accepts the user's operation. That is, the setting unit 12 can manually set the charging schedule by the user by setting the charging schedule based on the operation signal output from the input interface 15. The "user" referred to in the present disclosure is a person who uses the charge control system 10, for example, a resident of the house H1 and a user of the vehicle 3. Here, the number of users is not limited to one, and may be a plurality of users. For example, when there are a plurality of residents of the house H1 and one user of the vehicle 3, among the plurality of residents of the house H1, a resident other than the user of the vehicle 3 can also be a user. The setting unit 12 may automatically set the charging schedule according to information such as an electricity rate plan, a user's behavior pattern (including a life pattern), and a usage plan of the vehicle 3.

The control unit 13 has a function of controlling the charging of the storage battery 31. The control unit 13 controls the charging of the storage battery 31 according to the charging schedule set by the setting unit 12. That is, the control unit 13 operates in any of a plurality of states including a charging state and a stopped state for each time zone defined in the charging schedule, and controls the charging of the storage battery 31. In other words, since one of the operating states is assigned to each time zone according to the charging schedule, the control unit 13 controls the charging of the storage battery 31 according to the operating state assigned to each time zone. In the present embodiment, it is the charging system 2 that actually controls the charging of the storage battery 31, so that the control unit 13 indirectly controls the charging of the storage battery 31 by controlling the charging system 2.

Specifically, the control unit 13 outputs a "charging command" for instructing at least the charging facility 2 to start charging and a "stop command" for instructing the stop of charging. It controls the charging system 2 and controls the charging of the storage battery 31 by the charging system 2. For example, the control unit 13 outputs a charging command to charge the storage battery 31 during the charging state, and outputs a stop command to stop charging the storage battery 31 during the stopped time.

The control unit 13 charges the storage battery 31 in the charged state. That is, the control unit 13 charges the storage battery 31 during the time zone in which the charging state is designated (selected) in the charging schedule. Further, the control unit 13 does not charge the storage battery 31 in the stopped state. That is, the control unit 13 does not charge the storage battery 31 during the time zone in which the stop state is designated (selected) in the charging schedule.

The display control unit 14 controls to display various screens on the display unit 16. That is, the display control unit 14 generates a screen to be displayed on the display unit 16, and displays various screens on the display unit 16 by controlling the display unit 16. The "screen" referred to in the present disclosure means an image (including various objects, characters, etc.) displayed on the display unit 16. The display control unit 14 may display these screens on the display unit of an external device such as the information terminal 4 instead of the display unit 16 or together with the display unit 16.

The input interface 15 accepts the user's operation and outputs an operation signal according to the user's operation. The user's "operation" as used in the present disclosure includes an operation on a touch panel, a mechanical switch, or the like, an operation by voice input, a gesture, or the like. Therefore, the input interface 15 is realized by, for example, a touch panel display, a mechanical switch, a voice input unit, a camera, or the like. Alternatively, the input interface 15 may indirectly accept the user's operation on the external device such as the information terminal 4 by communicating with the external device. Alternatively, the input interface 15 may be provided in an external device such as the information terminal 4.

The display unit 16 displays the screen generated by the display control unit 14. The display unit 16 is realized by, for example, a display such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 16 displays the screen according to the video signal output from the display control unit 14.

In the present embodiment, the device control device 1 is equipped with a touch panel display, and the touch panel display functions as an input interface 15 and a display unit 16. However, the input interface 15 is not limited to the touch panel display, and may be, for example, a keyboard, a pointing device, a mechanical switch, or the like.

The external communication unit 17 communicates with external devices such as the information terminal 4 and the server 5 directly or indirectly via a network or a repeater. The "external device" referred to in the present disclosure is a device that is not included in the components of the charge control system 10, and as an example, in addition to the information terminal 4 and the server 5, the distribution board 61, the load 62, and the photovoltaic power generation equipment. Includes 7. As a communication method between the external communication unit 17 and the external device, an appropriate communication method of wireless communication or wired communication is adopted. In this embodiment, as an example, the external communication unit 17 has a standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or a low-power radio (specified low-power radio) that does not require a license. Adopt wireless communication that uses radio waves as a communication medium in accordance with.

Since the charge control system 10 only controls the charging of the storage battery 31, it is not essential that the storage battery 31 is charged according to the operating state. For example, in the charging state time zone, the charge control system 10 controls to charge the storage battery 31, but the storage battery 31 cannot be charged in the first place, for example, the storage battery 31 is fully charged. In this case, of course, the storage battery 31 is not charged.

1.2.3 Charging system The charging system 2 is a charging facility and is used for charging the storage battery 31 of the vehicle 3 (electric vehicle). Charging equipment is roughly divided into two types: normal charging and quick charging. In the present embodiment, the charging system 2 is a charging facility for normal charging that charges the storage battery 31 by receiving a supply of 200V (or 100V) single-phase alternating current. Further, the normal charging mode is classified into "Mode 1", "Mode 2" and "Mode 3" according to the charging control method (IEC61851-1). "Mode 1" is a method of supplying power to a vehicle from a charging facility that does not have a control circuit. "Mode 2" is a method in which a control circuit is built in the charging cable. "Mode 3" is a method in which a control circuit is built in the charging equipment. It is assumed that the charging system 2 adopts the "Mode 3" method.

The charging system 2 constitutes the charging control system 10 together with the device control device 1, and is a part of the charging control system 10. As shown in FIG. 1, the charging system 2 includes a communication unit (second communication unit) 21, a control unit (energization control unit) 22, a relay 23, a protection circuit 24, a vehicle communication unit 25, and a connection unit 26. ing.

The connection portion 26 includes a connection terminal to which the charging cable 8 having the plug 81 is electrically connected. The connection portion 26 is electrically connected to the storage battery 31 by electrically connecting the plug 81 of the charging cable 8 to the vehicle 3. In this way, the charging system 2 is electrically connected to the vehicle 3 via the charging cable 8 with the plug 81 connected to the vehicle 3. As a result, the charging system 2 can supply electric power to the vehicle 3 (storage battery 31) via the charging cable 8 and can communicate with the vehicle 3.

The relay 23 is inserted in the power supply path to the connection portion 26 connected to the storage battery 31. Specifically, in the charging system 2, the connection terminal with the distribution board 61 (power supply connection unit connected to the power supply) and the connection terminal with the charging cable 8 (connection unit 26 connected to the storage battery 31). The relay 23 is inserted between. As a result, if the relay 23 is on (conducting state), the distribution board 61 and the vehicle 3 are electrically connected, and the power supply source (power system 63 or the solar power generation facility 7) is connected to the vehicle 3 (the power system 63 or the solar power generation facility 7). It becomes possible to supply electric power to the storage battery 31). On the other hand, if the relay 23 is off (disconnected), the distribution board 61 and the vehicle 3 are electrically disconnected, and the power supply source (power system 63 or solar power generation facility 7) is connected to the vehicle 3 (storage battery). The power to 31) will not be supplied. The relay 23 may be either a mechanical relay having mechanical contacts or a semiconductor relay having no mechanical contacts, as long as it can be controlled by the energization control unit 22. In this embodiment, as an example, the relay 23 is realized by a mechanical relay.

The protection circuit 24 is a circuit that protects the vehicle 3 and the charge control system 10 by turning off the relay 23 when, for example, an abnormality such as an electric leakage or an overcurrent is detected. The protection circuit 24 may have an element that cuts off the supply of electric power to the vehicle 3 in addition to the relay 23.

The vehicle communication unit 25 communicates with the vehicle 3 directly or indirectly via a network or a repeater or the like. As a communication method between the vehicle communication unit 25 and the vehicle 3, an appropriate communication method of wireless communication or wired communication is adopted. In the present embodiment, as an example, the vehicle communication unit 25 communicates through the charging cable 8 to confirm the connection between the charging equipment 2 and the vehicle 3 and to confirm the state of the vehicle 3 by at least the CPLT (Control Pilot) signal. ..

The second communication unit 21 communicates directly with the device control device 1 (first communication unit 11) directly or indirectly via a network or a repeater or the like. As a communication method between the second communication unit 21 and the device control device 1 (first communication unit 11), an appropriate communication method of wireless communication or wired communication is adopted. In this embodiment, as an example, the communication method between the second communication unit 21 and the device control device 1 is wired communication conforming to a communication standard such as a wired LAN (Local Area Network). The communication protocol in the communication between the second communication unit 21 and the device control device 1 is, for example, Ethernet (registered trademark), ECHONET Lite (registered trademark), or the like.

The energization control unit 22 controls energization from the charging system 2 to the vehicle 3. The energization control unit 22 has a first mode and a second mode. The first mode is a mode (permission mode) for permitting charging of the storage battery 31 connected to the connection unit 26. In the first mode, the energization control unit 22 permits the storage battery 31 to be charged by turning on the relay 23 (conducting state) and energizing the vehicle 3 from the charging equipment 2. The second mode is a mode (non-permission mode) in which charging of the storage battery 31 connected to the connection unit 26 is not permitted. In the second mode, the energization control unit 22 does not allow the storage battery 31 to be charged by turning off the relay 23 (cutting off state) and stopping the energization from the charging system 2 to the vehicle 3.

The energization control unit 22 can be realized by a computer system including one or more memories and one or more processors. That is, the function of the energization control unit 22 is realized by executing the program recorded in one or more memories of the computer system by one or more processors. The program may be pre-recorded in a memory, provided through a telecommunication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

1.2.4 Presentation system The presentation system 18 is provided in the device control device 1. That is, the device control device 1 functions as the presentation system 18. The presentation system 18 includes an acquisition unit 181, a presentation unit 182, a first calculation unit 183, and a second calculation unit 184.

The acquisition unit 181 is configured to acquire information on the moving distance and the amount of electric power used in a predetermined period of the moving body (vehicle 3) whose power source is electric power. That is, the acquisition unit 181 executes an acquisition step of acquiring information on the moving distance and the amount of electric power used in a predetermined period of the moving body (vehicle 3) whose power source is electric power. Here, the moving distance (moving distance of the moving body in a predetermined period) means the distance (total distance) of the moving body moved in a predetermined period. The amount of power used (the amount of power used by the mobile body in a predetermined period) means the amount of power used by the mobile body in a predetermined period. Therefore, it can be said that the electric energy used is the electric energy consumed when the moving body travels by the moving distance. The predetermined period is not particularly limited, but as an example, it may be a period corresponding to one month. Of course, the predetermined period may be a period of one day, one week, one year, or the like, and may be changed as appropriate.

Here, the acquisition unit 181 can acquire the moving distance and the amount of power used by various methods. For example, the acquisition unit 181 may acquire both the travel distance and the amount of power used from an external device. Alternatively, the acquisition unit 181 may acquire one of the moving distance and the amount of power used from an external device and calculate the other from the one.

More specifically, the acquisition unit 181 may acquire information on the moving distance from the moving body (vehicle 3). As an example, the acquisition unit 181 can acquire information on the travel distance from the vehicle 3 through the charging system 2 or the server 5. In addition, the acquisition unit 181 may acquire information on the power consumption of the mobile body (vehicle 3) in a predetermined period as information on the power consumption. That is, the power consumption of the mobile body may be adopted as the power consumption. As an example, the acquisition unit 181 can acquire information on the power consumption from the vehicle 3 through the charging system 2 or the server 5. Alternatively, the acquisition unit 181 may acquire information on the amount of charging power in a predetermined period as information on the amount of power used. That is, the charging power amount of the mobile body may be adopted as the power consumption amount. The charging electric energy may be the electric energy used by the charging system 2 to charge the vehicle 3. This is based on the assumption that the charging system 2 charges the vehicle 3 by the amount of power consumed by the vehicle 3. As an example, the acquisition unit 181 can acquire information on the amount of charging power from the charging system 2 or the distribution board 61.

Further, the acquisition unit 181 may calculate the other from one of the moving distance and the amount of power used. For example, when the acquisition unit 181 acquires the electric energy used from an external device (charging system 2 or distribution board 61), the acquisition unit 181 relates to the moving distance from the electric energy used and the electric energy consumption rate of the moving body (vehicle 3). Information may be obtained. If the travel distance is D, the electric energy used is Ue, and the electric energy consumption rate is Ce, D is given by Ce × Ue. On the contrary, when the moving distance is acquired from the vehicle 3, the acquisition unit 181 may acquire information on the electric energy used from the moving distance and the electric energy consumption rate of the moving body (vehicle 3). If the moving distance is D, the electric energy used is Ue, and the electric energy consumption rate is Ce, the Ue is given by D / Ce. The electric energy consumption rate may be a predetermined value (for example, a value published by the manufacturer of the vehicle 3) for the moving body, or an actually measured value (an average value of the electric energy consumption rate in a predetermined period). ) May be.

The presentation unit 182 is configured to present comparative information on electricity charges and fuel costs. Here, the electricity charge means an electricity charge corresponding to the amount of electricity used (the amount of electricity used acquired by the acquisition unit 181). The fuel cost means the fuel cost required for the comparative moving body whose power source is fuel to move the moving distance (the moving distance acquired by the acquisition unit 181). In the present embodiment, the electricity charge is calculated by the first calculation unit 183. The fuel cost is calculated by the second calculation unit 184.

The first calculation unit 183 is configured to calculate the electricity charge from the amount of electricity used and the unit price of the electricity charge. As an example, if the amount of electricity used is Ue, the unit price of electricity is Re, and the electricity price is Pe, Pe is given by Ue × Re. The electricity rate unit price Re may be input in advance at the time of manufacturing the presentation system 18, may be input by the user using the input interface 15 or the information terminal 4, and the first calculation unit 183 may input the electricity rate at the time of calculating the electricity rate. It may be obtained from the server 5.

The second calculation unit 184 is configured to calculate the fuel cost from the fuel consumption rate and the travel distance of the comparative mobile body. As an example, if the fuel consumption rate is Cf, the travel distance is D, the fuel unit price Rf, and the fuel cost is Pf, Pf is given by Rf × D / Cf. The fuel unit price Rf may be input in advance at the time of manufacturing the presentation system 18, may be input by the user using the input interface 15 or the information terminal 4, and the second calculation unit 184 may be used for the fuel cost Pf.

A comparative mobile is a virtual mobile for comparison with a mobile. The comparative mobile body is different from the mobile body whose power source is electric power, and assumes a mobile body whose power source is fuel. Examples of the comparative moving body include a moving body having an internal combustion engine (gasoline vehicle, diesel vehicle, LPG gas vehicle, etc.) and a fuel cell vehicle.

The second calculation unit 184 determines the fuel consumption rate Cf of the comparative mobile body by using at least one of the body type of the mobile body, the size of the mobile body, and the fuel type of the comparative mobile body. Examples of body types include sedans, coupes, SUVs, vans (wagons) and the like. Examples of sizes include light, compact, normal (small), normal (medium), and normal (large). Examples of fuel types include gasoline and light oil. Gasoline can be classified into a plurality of types based on the octane number standard. According to the Japanese Industrial Standards (JIS), gasoline can be classified into regular gasoline and high-octane gasoline. In the present embodiment, the second calculation unit 184 determines the body type of the moving body, the size of the moving body, and the fuel type of the comparative moving body from the information (main specifications, etc.) of the moving body. The second calculation unit 184 makes the body type of the comparative mobile body the same as the body type of the moving body, and makes the size of the comparative mobile body the same as the size of the moving body. Then, the second calculation unit 184 determines the fuel consumption rate Cf from the combination of the body type, size, and fuel type of the comparative mobile body. As an example, the second calculation unit 184 has a correspondence relationship between the combination of the body type, size, and fuel type of the comparative mobile body and the fuel consumption rate Cf, and determines the fuel consumption rate Cf from this correspondence relationship.

The presentation unit 182 generates comparative information based on the electricity charge calculated by the first calculation unit 183 and the fuel cost calculated by the second calculation unit 184. FIG. 3 is a graph (bar graph) showing the relationship between electricity charges and fuel costs, which is an example of comparative information. In FIG. 3, G10 shows the electricity rate and G11 shows the fuel cost. Further, the bar graph of FIG. 3 includes an arrow A10. The arrow A10 indicates the difference between the electricity charge and the fuel cost according to the length, and indicates that the electricity charge is lower than the fuel cost depending on the direction. The presentation unit 182 may present the comparison information to the user by displaying it on the display unit 16, or may present it to the user by transmitting it to the information terminal 4 or the server 5 through the external communication unit 17.

Further, the presentation system 18 determines the fuel consumption rate Cf of the comparative moving body corresponding to the vehicle 3, and calculates the fuel cost Pf from the moving distance D and the fuel consumption rate Cf (S13). Then, the presentation system 18 generates and presents comparison information from the electricity charge Pe and the fuel cost Pf (S14).

The flowchart of FIG. 4 is merely an example of the operation of the presentation system 18. For example, the order of step S12 and step S13 may be reversed, or step S12 and step 13 may be executed in parallel.
