Description

Method and apparatus for providing recommended charging station information considering power dissipation {Method and apparatus for providing recommend information on electronic vehicle charging station}

The present invention relates to a recommended charging station information method and apparatus thereof in which power distribution is considered, and more particularly, to smoothly perform power distribution by region by guiding a recommended charging station in consideration of power distribution for each region in a battery powered electric vehicle. A method and apparatus are disclosed.

Recently, due to environmental problems such as air pollution caused by exhaust gas of cars driven by internal combustion engines using fossil fuels and global warming caused by carbon dioxide, hybrid cars driven by electric power have been widely used. There is also a lot of research into electric vehicles.

Electric vehicles driven only by electricity have been developed a long time ago, but the power storage efficiency per weight of a battery that can be implemented at present is not yet in practical use. That is, the weight of the battery is too large to store the amount of power enough to move the appropriate distance, and when the weight of the battery is reduced, the amount of power stored is not enough, the distance that can be moved by one charge is shortened. As far as is known, electric vehicles have been developed that can drive approximately 200 km on a single charge. In the future, battery technology is expected to provide electric vehicles that can travel longer distances with a single charge.

On the other hand, when an electric vehicle is spreading, a charging station for power charging should be provided at an appropriate location in each region, such as a gas station supplying fuel to a vehicle using fossil fuel. At this time, when the demand for charging is concentrated in a charging station in one region and the power supply range of the region is exceeded, smooth power supply may be difficult and operation of the electric vehicle may become difficult. In addition, even if electric vehicles are induced to achieve power distribution, power demand in a particular region may temporarily increase significantly.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

1 schematically shows a technical configuration for providing a method for providing a recommended charging station according to the present invention.

The power management server 10, the terminal 20 of the charging station, and the electric vehicle 30 are connected to exchange information with each other through an information communication network. An information network can be any network that allows data to be exchanged between devices located at different locations, including the Internet. The power management server 10 is installed on the electricity supplier side to identify the real-time power demand in each region and allow the operator to plan the power distribution and distribution if necessary. The terminal 20 of the charging station is installed in each charging station and transmits the details to the power management server 10 when a charging service occurs and receives information on the price therefrom. The electric vehicle 30 is provided with a device for providing the driver with location information of the recommended charging station, as will be described later. The device checks the state of charge of the battery installed in the electric vehicle, provides information to the power management server 10, and guides the driver to the recommended charging station.

FIG. 2 schematically shows an apparatus installed in an electric vehicle in order to provide location information of a recommended charging station to the electric vehicle in consideration of power distribution, and FIG. 3 is installed in the power provider side. A power management server is shown schematically.

The electric vehicle 30 receives power from a battery and is driven using a motor. The state of charge of the battery is monitored by the battery manager 200. The battery manager 200 checks the state of charge of the battery in real time or periodically, and provides a warning message to the driver when the remaining charge level of the battery falls below a predetermined level so that the battery can be charged before being completely discharged. In addition, the electric vehicle 30 may be provided with a navigation device 300 for guiding a movement route to the destination. The navigation device 300 includes a GPS sensor and obtains information about the current location of the vehicle based on a signal received from a GPS satellite, and searches and guides a route to a destination based on the stored geographical information.

Meanwhile, in the present embodiment, communication between devices provided in the electric vehicle 30, such as the battery manager 200 and the navigation device 300, is performed by a power line communication method. In the case of using the power line communication system, wiring in the vehicle is simplified because there is no need to wire separately to transmit a communication signal.

As shown in FIG. 2, the recommended charging station information providing apparatus 100 includes a control unit 110, a battery remaining amount checking module 126, a driving distance calculation module 122, a vehicle positioning module 124, and a data management unit ( 130, a user interface 140, and a communication module 150, which are installed in the electric vehicle 30 to provide the driver with information about the current state of the vehicle including the battery level and location information of the recommended charging station. . Location information of the recommended charging station is provided from the power management server 10 as described later.

In this embodiment, the communication module 150 consists of a power line communication modem. As described above, the communication between the other devices of the electric vehicle and the recommended charging station information providing device is made by a power line communication method. Accordingly, the recommended charging station information providing apparatus 100 includes a power line communication modem 150 for communication with other devices. However, the present invention is not limited to the case where the communication between the devices is made by the power line communication method, it is obvious that various communication methods including conventionally used CAN communication can be applied. The power line communication modem 150 transmits the charging station location information request including the information on the location and the driving distance of the electric vehicle 30 to the power management server 10 and the recommended charging station location information from the power management server 10. Receive

The battery remaining amount checking module 126 checks the battery remaining amount of the electric vehicle 30 and compares it with a predetermined reference value. To this end, the battery remaining amount checking module 126 receives information on the remaining battery level from the battery manager 200 of the electric vehicle 30 through the power line communication modem 150. The reference value may be preset in the manufacture of the electric vehicle 30 or set by the user. The set reference value is stored in the data manager 130, for example.

The driving distance calculation module 122 calculates the distance that the electric vehicle 30 can travel based on the battery remaining amount confirmed by the battery remaining amount checking module 126. Alternatively, the driving distance calculation module 122 may receive information on the driving distance based on the remaining battery amount from a trip computer of the electric vehicle 30.

The vehicle positioning module 124 receives information about the current position of the vehicle from the navigation device 300 of the electric vehicle 30 through the power line communication modem 150. Vehicle positioning can be done periodically or at real time at regular intervals. Alternatively, the vehicle position may be checked only when the battery level is lower than the reference value. In addition, the vehicle positioning module 124 may be provided from the navigation device 300 as well as information on the position of the electric vehicle as well as information on the direction in which the electric vehicle is moving. Information about the available distance and the position and the moving direction of the vehicle according to the remaining battery amount is used as information for determining the position of the recommended charging station in the power management server 10, as will be described later.

The data manager 130 stores and manages data such as an identifier of the electric vehicle and a reference value of the remaining battery level. The identifier of the electric vehicle may be a vehicle registration number, for example. In addition, the data manager 130 stores and manages information including location information of the recommended charging station received from the power management server 10.

When the remaining battery level determined by the battery remaining amount checking module 126 is equal to or less than a predetermined reference value, the controller 110 confirms the driving possible distance calculated by the driving distance calculation module 122 and the vehicle position checking module 124. The charging station location information request including the vehicle location information and the identification symbol of the electric vehicle is transmitted to the power management server 10. The communication processor 400 of the electric vehicle transmits the charging station location information request received from the control unit 110 through the power line communication modem 150 to the power management server 10. Communication between the communication processor 400 and the power management server 10 may be performed in various ways, including existing mobile communication technologies. In addition, the controller 110 stores the recommended charging station location information received from the power management server 10 in the data manager 130.

The user interface 140 is an output device for providing the driver with information on the status of the vehicle, such as a battery level and a driving distance, and information on a recommended charging station received from the power management server 10. Means for receiving input, for example, a touch screen type input device. In addition, when the driver wants to charge even when the battery level is not smaller than the reference value, the driver may transmit the recommended charging station information request through the user interface.

3 shows a power management server 10 according to an embodiment of the present invention. The power management server 10 includes a power demand prediction module 13, a recommended charging station determination module 14, a power charge determination module 12, and a data manager 15, and receives a request for charging station location information from an electric vehicle. Provide location information of recommended charging stations. The recommended charging station for each electric vehicle is determined by considering the power distribution.

The recommended charging station determining module 14 determines the recommended charging station for each electric vehicle based on the request for the charging station location information received from the plurality of electric vehicles. Determination of the recommended charging station is made in consideration of power distribution by region in cooperation with the power demand prediction module 13, as will be described later.

The power demand prediction module 13 calculates the estimated power demand for each region based on the request for the charging station location information received from the plurality of electric vehicles. As used herein, the term "region" refers to a unit region for power supply. The power management center in which the power management server 10 is installed monitors power distribution by region and allows power demand to occur within a range that can be supplied by region.

The data manager 15 stores and manages information about electric power rates and all charging stations and information about each electric vehicle in which the request for charging station location information is received.

The power management server 10 includes a communication processor 16 to receive the charging station location information request from the electric vehicle and transmit the recommended charging station location information to the electric vehicle. Communication between the electric vehicle 30 and the power management server 10 may be accomplished in a variety of ways, including existing mobile communication technologies.

On the other hand, the power management server 10 can exchange information with each charging station 20. For example, the charging station transmits information about the electric vehicle to the power management server 10 when it is charged. The transmitted information includes the identifier of the electric vehicle and information on the amount of charged power. The power management server 10 determines whether the corresponding charging station corresponds to the recommended charging station of the electric vehicle, and then determines the electric charge for the electric vehicle based on this. Determination of the power bill is made by the power bill determination module 12.

In addition, the power management server 10 may further include a power distribution determination module (not shown) for determining the power distribution amount by region based on the region-specific estimated power demand amount provided by the power demand estimation module 13. The power distribution determination module adjusts an existing power distribution setting when the expected power demand in a specific region is expected to exceed a preset power distribution, so that smooth power supply can be achieved.

4 illustrates a method of providing electric vehicle with recommended charging station information considering power distribution according to the present invention.

The recommended charging station information providing apparatus 100 installed in the electric vehicle 30 checks the battery remaining amount and calculates a driving distance when the checked battery remaining amount is smaller than a predetermined standard (S101). Information on the estimated driving distance is transmitted to the power management server 10 as a charging station location information request together with the identification symbol of the electric vehicle and the location information of the vehicle (S102). The transmission of the request can be made automatically or at the driver's choice. In addition, even if the battery level is not smaller than the reference value, if the driver wants to charge it is good to be able to transmit the recommended charging station information request. This is because, as will be described later, the electric charge can be discounted when the electric power is charged at the recommended charging station.

The power management server 10 receives the charging station location information request and calculates an estimated amount of power demand for each region based on the information included therein. At the same time, the power management server 10 determines one or more charging stations that the electric vehicle 30 recommends to charge (S103). The determined location information of the recommended charging station is stored in the data management unit 15 of the power management server 10 and transmitted to the electric vehicle (S104). The recommended charging station location information received is displayed by the recommended charging station information providing apparatus 100 of the electric vehicle 30 in the form of a list or location information on a map. The driver can select a charging station to charge his vehicle based on this information. FIG. 5 shows an example of a state where the recommended charging station is displayed in a map form on a screen of a device for guiding the location of the recommended charging station installed in the electric vehicle. On the other hand, when the driver selects any one of the plurality of recommended charging stations displayed on the list or the map, the location information of the corresponding charging station is transmitted to the navigation device 300 of the electric vehicle, and the navigation device 300 receives the location of the received charging station. Based on the information, the movement route from the current vehicle position to the corresponding charging station can be guided.

Communication between the electric vehicle 30 that requires charging and the power management server 10 may be performed periodically at predetermined intervals. In this case, power demand forecasting can be more accurate. The power management server 10 stores and manages the updated information in the data manager 15.

When the electric vehicle is charged at the recommended charging station, the charging station transmits information on the identification symbol and the power charging amount of the electric vehicle to the power management server (S106). When the electric vehicle enters the charging station or when charging is completed, it is possible to transmit its identifier to the charging station (S105). If the identification number of the electric vehicle is a vehicle registration number, the charging station may input it. The power management server determines whether the corresponding charging station is included in the recommended charging station of the electric vehicle, and determines the electric power fee information based on this. For example, if the charging station corresponds to the recommended charging station of the electric vehicle, a discounted electric charge may be applied. To this end, the power management server transmits power charge information determined according to the power charge policy to the corresponding charging station (S107). Since the recommended charging station has been determined in consideration of regional power distribution, when the electric vehicle is charged at the recommended charging station, power distribution may be smoothly performed by region. Therefore, applying a discounted power rate to induce charging at the recommended charging station may be one way to induce power distribution.

On the other hand, even if electric power distribution is induced by region through a power rate discount, the supply and demand of the region may not be smooth due to the increase in the number of electric vehicles that need to be charged in a particular region temporarily. The power management server can adjust the regional power distribution so that there is no problem with the power supply in advance.

An example of a method for determining a recommended charging station is as follows: First, the power management server identifies a charging station within a driving distance of an electric vehicle that has transmitted a charging station location request. From the identified charging stations, preselect a charging station in the area where the electric vehicle is located as the recommended charging station for the electric vehicle. Next, the estimated power demand of the region is calculated based on the location information of the pre-selected recommended charging station. If the estimated electric power demand of the corresponding region exceeds the predetermined standard, the charging station in another region within the range of driving can be determined as the recommended charging station. If the specified criteria are not exceeded, the preselected charging station is determined as the recommended charging station.

The charging station location information request transmitted from the electric vehicle may include information on the direction of the electric vehicle traveling. In this case, the power management server may determine the recommended charging station in consideration of the driving direction of the electric vehicle, and the driver of the electric vehicle may be charged while maintaining the driving to the destination as much as possible. FIG. 6 shows an example of a state where the recommended charging stations guided in consideration of the driving direction of the vehicle are displayed in a map format on a device for guiding the positions of the recommended charging stations installed in the electric vehicle.

Although the invention has been described in detail based on the embodiments shown in the accompanying drawings, it is apparent that various modifications are possible without departing from the scope of the invention. Nothing described herein is intended to narrow the scope of the invention to the scope of the appended claims. The foregoing examples are for illustrative purposes only and are not intended to exclude those having other embodiments.
