Detailed Description
Embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical solutions of the present application, and thus are only examples, and are not intended to limit the scope of protection of the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the term "comprising" and any variations thereof in the description of the present application and claims and in the description of the figures above is intended to cover a non-exclusive inclusion.
In the description of the embodiments of the present application, the technical terms "first," "second," etc. are used merely to distinguish between different objects and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, a particular order or a primary or secondary relationship.

In the related art, when a user inserts a charging gun of a charging post into a charging socket of an electric vehicle, a battery management system of the electric vehicle performs a charging process when detecting a charging gun signal.
However, the charging mode in the related art is not flexible enough, and the charging requirement in part of application scenes cannot be met.
For example, after the vehicle finishes the charging process, when the user is required to pull the charging gun out of the charging socket and insert the charging gun into the charging socket again, the battery management system of the electric vehicle detects the charging gun signal again so as to perform the charging process. Therefore, the charging mode in the related art cannot meet the charging requirement in the continuous charging and discharging application scenario.
For another example, in an electric vehicle in which a battery can be replaced, when a user inserts a charging gun into a charging socket of the electric vehicle, a battery management system of the electric vehicle executes a charging process when detecting a charging gun signal. The manner in which a user frequently uses a charging gun to charge a replaceable battery in an electric vehicle can affect not only the service life of the replaceable battery, but also the operation and management of the replaceable battery. As can be seen, the charging method in the related art cannot meet the charging requirement of the electric vehicle with the replaceable battery.
In order to solve the technical problem that the charging mode in the related art is not flexible enough, the embodiment of the application provides: the switch is arranged between the charging gun connection signal detection interface of the charging socket and the battery management system, and the battery management system is controlled to execute a charging flow flexibly in a mode of controlling the opening and closing states of the switch, so that charging requirements under various application scenes can be met.
Fig. 1 is a schematic diagram of an application environment provided in some embodiments of the present application, and as shown in fig. 1, the application environment in the embodiments of the present application may include: charging pile 10, consumer 11 and remote device 12. The charging gun of the charging pile 10 may be plugged into a charging socket of the electric device 11, so as to charge a battery in the electric device 11. In addition, when receiving the charging instruction sent by the remote device 12, the electric device 11 may charge the battery in the electric device 11 through the charging pile 10.
The electric equipment provided by the embodiment of the application can be, but is not limited to, an electric toy, an electric tool, an electric vehicle, a ship, a spacecraft and the like. Among them, the electric toy may include fixed or mobile electric toys, for example, electric car toys, electric ship toys, electric plane toys, and the like, and the spacecraft may include planes, rockets, space planes, and spacecraft, and the like.

For example, considering the pull-down resistance of the charging gun, the battery management system 22 may determine whether the charging gun of the charging post is successfully plugged into the charging socket 20 of the powered device according to the signal voltage in the charging gun connection signal detection interface I; if the signal voltage in the charging gun connection signal detection interface I is the default first preset voltage, the battery management system 22 may determine that the charging gun of the charging post is not successfully plugged into the charging socket 20 of the electrical device; if the signal voltage in the charging gun connection signal detection interface I is the second preset voltage, the battery management system 22 may determine that the charging gun of the charging post is successfully plugged into the charging socket 20 of the electrical device, where the second preset voltage may be one half of the first preset voltage.
Of course, the battery management system 22 may also determine whether the charging gun of the charging post is successfully plugged into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I in other manners, which is not limited in the embodiment of the present application.
In this embodiment, the controller 21 may be communicatively connected to the switch K, so as to control the opening and closing states of the switch K. It should be appreciated that the controller 21 may be communicatively coupled to the control terminal of the switch K.

In a possible implementation manner, the charging information related to the embodiment of the present application may include, but is not limited to: SOC of the battery and/or battery state of charge in the powered device, wherein the battery state of charge may be used to indicate a charged or uncharged state. Correspondingly, the preset switching conditions referred to in the embodiments of the present application may include, but are not limited to: SOC is below a preset threshold and/or battery state of charge is uncharged.
It should be understood that the controller 21 may obtain the battery state of charge SOC and/or the battery state of charge of the battery from the battery management system 22 in real time or at preset intervals, and may also obtain the battery state of charge SOC and/or the battery state of charge of the battery from other devices, which is not limited in this embodiment of the present application.
Note that the charging information may also include: other information of the battery that may be used to indicate the remaining capacity of the battery (e.g., battery voltage, etc.) and other information that may be used to indicate whether the battery is charged.
In another possible implementation manner, the charging information related to the embodiment of the present application may include, but is not limited to: a second charging instruction for the battery sent by the remote device, or a charging instruction for the battery sent by other devices. Correspondingly, the preset switching conditions referred to in the embodiments of the present application may include, but are not limited to: and receiving the second charging instruction.
Of course, the charging information in the embodiment of the present application may also include other information related to charging, which is not limited in the embodiment of the present application.
In the following embodiments of the present application, description will be made of the content of "in the case where the charging information is different information, the controller 21 controls the closed state of the switch K".
In a possible implementation manner, the charging information includes: the controller 21 is specifically configured to: when the SOC is lower than a preset threshold value and/or the battery charging state is uncharged, the control switch K is switched from the first state to the second state; after a preset time period for switching the control switch K from the first state to the second state, the control switch K can be switched back from the second state to the first state; the first state is a closed state, and the second state is an open state.
In this embodiment, the controller 21 may control the switch K to switch from the default first state (i.e. the closed state) to the second state (i.e. the open state) when the battery is not charged, which is equivalent to a state simulating the removal of the charging gun from the charging socket, so that the battery management system may detect the charging gun connection signal in the charging gun connection signal detection interface again.
Further, the controller 21 is further configured to control the switch K to switch from the second state (i.e. the open state) to the default first state (i.e. the closed state) after the control switch K is switched from the first state to the second state for a preset period of time, which is equivalent to simulating the state of inserting the charging gun into the charging socket, so that the battery management system 22 can execute the charging process when determining that the charging gun of the charging pile is successfully inserted into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I, and the SOC of the battery is lower than the preset threshold, so as to meet the continuous charging and discharging requirements of the electric device.
It should be appreciated that, in the case where it is determined from the charging gun connection signal that the charging gun of the charging post is not successfully inserted into the charging socket 20 of the electric device, or the SOC of the battery is not lower than the preset threshold, the battery management system 22 may temporarily not perform the charging process until it is detected that the charging gun is successfully inserted into the charging socket 20 of the electric device, and the SOC of the battery is lower than the preset threshold. Therefore, the embodiment of the application not only can avoid the potential safety hazard caused by executing the charging process under the condition that the charging gun is not inserted as much as possible, so that the use safety of the battery can be improved, but also is beneficial to reducing the charging frequency of the battery by executing the charging process under the condition that the SOC of the battery is lower than the preset threshold value, so that the service life of the battery is prolonged.
In still another exemplary embodiment of the present application, when the SOC is lower than the preset threshold and the battery charging state is uncharged, the controller 21 may control the switch K to switch from the default first state (i.e. the closed state) to the second state (i.e. the open state), which is equivalent to a state simulating the removal of the charging gun from the charging socket, so that the battery management system may detect the charging gun connection signal in the charging gun connection signal detection interface again.
Further, the controller 21 is further configured to control the switch K to switch from the second state (i.e. the open state) to the default first state (i.e. the closed state) after the control switch K is switched from the first state to the second state for a preset period of time, which is equivalent to a state simulating that the charging gun is inserted into the charging socket, so that the battery management system 22 can execute the charging process when determining that the charging gun of the charging pile is successfully inserted into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I, so that the continuous charging and discharging requirements of the electric device can be satisfied without the battery management system 22 determining whether the SOC of the battery is lower than the preset threshold. Therefore, the embodiment of the application can simplify the charging control flow on the basis of improving the use safety of the battery and being beneficial to improving the service life of the battery.
It should be understood that, the controller 21 may also control the closed state of the switch K in the case where the SOC is lower than the preset threshold, so that the battery management system 22 may execute the charging process when it is determined that the charging gun of the charging post is successfully inserted into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I, and the battery charging state is uncharged, so as to meet the continuous charging and discharging requirements of the electric device.
In summary, in the embodiment of the application, the controller in the electric equipment can instruct the battery management system to execute the charging process by switching the control switch from the default closed state to the open state and switching the open state back to the closed state under the condition that the SOC is lower than the preset threshold and/or the charging state of the battery is uncharged, so that the continuous charging and discharging requirements of the electric equipment can be met.
Further, the controller 21 is further configured to send a first charging instruction to the charging pile, where the first charging instruction is configured to instruct the charging pile to charge the battery through the charging gun after the switch K is switched from the second state back to the first state.
The controller 21 may send the first charging command to the charging pile by a message, which is not limited in the embodiment of the present application, of course, may also send the first charging command by other manners.
Therefore, the triggering mode of the embodiment of the application is faster and more convenient.
In another possible implementation, the charging information may include, but is not limited to: the controller 21 is specifically configured to control the switch K to switch from the first state to the second state when receiving the second charging instruction; wherein the first state is an open state and the second state is a closed state.
For example, the second charging instruction may be sent to the controller 21 by the remote device after receiving the charging request of the electric device. For example, the second charging instruction may be sent to the controller 21 after checking a request reason or the like carried in the charging request after the remote device receives the charging request of the electric device.
Still another example, the second charging instruction may be sent to the controller 21 for the remote device upon detecting that the charging condition is satisfied.
Of course, the second charging instruction may also be sent to the controller 21 by the remote device in other cases, which is not limited in the embodiment of the present application.
In this implementation manner, the controller 21 may switch the control switch K from the default first state (i.e., the open state) to the second state (i.e., the closed state) when receiving the second charging instruction, so that the battery management system 22 may execute the charging procedure when determining that the charging gun of the charging post is successfully plugged into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I.
Therefore, in the embodiment of the application, under the condition that the controller in the electric equipment receives the second charging instruction, the control switch is switched from the default open state to the closed state, so that the frequency of charging the replaceable battery in the electric vehicle by the user through the charging gun can be controlled, and the service life of the replaceable battery is prolonged.
Further, the charging information may further include a battery state of charge SOC of the battery in the electric device, and the controller 21 may switch the control switch K from the default first state (i.e. the open state) to the second state (i.e. the closed state) when the second charging instruction is received and the SOC is lower than the preset threshold, so that the battery management system 22 may execute the charging procedure when it is determined that the charging gun of the charging post is successfully plugged into the charging socket 20 of the electric device according to the charging gun connection signal in the charging gun connection signal detection interface I. Therefore, in the embodiment of the application, by executing the charging process when the second charging instruction is received and the SOC of the battery is lower than the preset threshold, the frequency of charging the replaceable battery in the electric vehicle by the user using the charging gun can be further controlled, so that the service life of the replaceable battery can be further prolonged.
Further, the controller 21 is also configured to switch the control switch K from the second state (i.e., the closed state) back to the first state (i.e., the open state) in the event that it is determined that the battery charging is completed, so that the user can be prevented from frequently charging the replaceable battery in the electric vehicle using the charging gun.
In summary, the electric equipment of the embodiment of the application may include: a charging receptacle, a controller, and a battery management system. The charging gun connection signal detection interface of the charging socket is provided with a switch with the battery management system, and the controller is in communication connection with the switch. The controller is used for controlling the opening and closing states of the switch according to the charging information so as to instruct the battery management system to execute a charging process. Therefore, in the embodiment of the application, the switch is arranged between the charging gun connection signal detection interface of the charging socket and the battery management system, and the mode of controlling the opening and closing states of the switch according to the charging information is beneficial to flexibly controlling the battery management system to execute the charging process, so that the charging requirements under various application scenes can be met.

Further, the controller 21 may control the low voltage relay K1 to switch from the default open state to the closed state upon receiving the second charging instruction sent by the remote device, so that the battery management system 22 may execute the charging procedure when determining that the charging gun of the charging post is successfully plugged into the charging socket 20 of the electric device according to the charging gun connection signal in the CC2 interface. For example, the controller 21 may control the low-voltage relay K0 to switch from the open state to the closed state by outputting a high-voltage signal to the control terminal of the low-voltage relay K1.
Further, the controller 21 may also control the low-voltage relay K1 to switch from the closed state back to the default open state in the case where it is determined that the battery charging is ended. For example, the controller 21 may control the low-voltage relay K0 to switch from the closed state back to the default open state by stopping the output of the high-voltage signal to the control terminal of the low-voltage relay K1.
It should be noted that, the controller may adopt a corresponding mode according to the working mechanism of the low-voltage relay K0 in the mode of controlling the low-voltage relay K1 to open and close, which is not limited in the embodiment of the present application.
To sum up, in this application embodiment, under the condition that the controller of electric vehicle received the second instruction of charging, the mode of the open and shut state of control low voltage relay K1 can control the frequency that the user used the rifle of charging to charge for the removable battery in the electric vehicle, is favorable to improving the life of removable battery. Therefore, the charging control mode of the embodiment of the application can meet the charging requirement of the electric vehicle with the replaceable battery.
