[0069] The application scenario of the scheme of the present application is clearly described with reference to Figure 5 The hardware framework of the vehicle discharge control of the present application.

[0070] Discharge vehicle 101: can supply power to external intelligent discharge device 110 through DC socket. Vehicle end human-computer interaction system 102 (also known as vehicle MMI, Multi Media Interface): vehicle and discharge device information display, discharge authorization and control, with discharge reservation, energy supplement planning, and vehicle return trip remaining power protection intelligent function. High-voltage power battery system 103 (BMS, Battery Management System): can charge and discharge, and integrates power battery management system, interacts with intelligent discharge device 110, and discharges control. Vehicle control unit system 104 (VCU, Vehicle control unit): whole vehicle discharge system main control module, and key function control such as power-on and power-off of discharge vehicle 101. Vehicle telematics controller 105 (TBOX, Telematics-BOX): connects discharge vehicle 101 and cloud service system 107, bidirectionally transmits working state information and synchronously controls instructions. Mobile communication client 106 (such as mobile smart phone, and installs APP (Application) which realizes interaction with TBOX): has authorization control and working state query function, remotely starts and stops discharge system through mobile communication client 106, has discharge reservation, energy supplement planning, and vehicle return trip remaining power protection intelligent function.

[0071] Referring to Figure 2 The first embodiment of the vehicle discharge control method comprises:

[0072] Step S10: after the power battery of the vehicle is successfully connected with the discharge gun, output discharge authorization information through the vehicle MMI and / or mobile smart device associated with the vehicle.

[0073] It should be noted that in the present embodiment, the above-mentioned vehicle discharging control method can be used for external discharging control of the vehicle power battery, that is, using the power of the vehicle power battery for external use of the user. The implementation subject of the above-mentioned vehicle discharging control method can be a vehicle or an electronic device installed on the vehicle. Generally, the interface for discharging the power battery and the charging interface for charging are the same interface, so currently for most new energy vehicles, when discharging through the charging interface, it may be misjudged as charging, and during the discharging process of the power battery, the vehicle usually does not output the information related to discharging, so for the user, the user usually starts and stops discharging by plugging and unplugging the discharging gun, so it is very inconvenient for the user to use the discharging function of the vehicle. To solve the above problems, the present application provides a vehicle discharging control method, which outputs the related information of the vehicle power battery to the user, and provides multiple interaction ways for discharging process control, thereby improving the user experience during the use of the vehicle discharging function.

[0074] For example, during the actual use of the vehicle discharging function by the user, the user usually manually inserts the discharging gun into the discharging interface of the vehicle (that is, into the DC charging and discharging socket of the vehicle). In order to ensure good connection, the vehicle will detect the connection state of the discharging gun, for example, inserting the discharging gun into the DC charging and discharging socket will trigger the power battery management system to detect the state of the power battery and the discharging gun (for reference, the detection of the charging gun and the power battery during the charging process will not be described here). After ensuring that the power battery and the discharging gun are successfully connected, the vehicle can output discharging authorization information through the vehicle infotainment interface and / or a mobile intelligent device associated with the vehicle. The discharging authorization information output on the vehicle infotainment interface can be transmitted and output through the vehicle network. The discharging authorization information output on the mobile intelligent device associated with the vehicle can be uploaded to the cloud through the TBOX of the vehicle, and then the cloud can send the discharging authorization information to the mobile intelligent device, and the mobile intelligent device can output the discharging authorization information. On the one hand, the user can know that the vehicle is discharging when seeing the discharging authorization information, and on the other hand, multiple ways for discharging control can be provided to the user, and the user can choose a convenient control way to control the discharging process, thereby ensuring the user experience.

[0075] It should be further noted that after determining that the power battery and the discharging gun are successfully connected, the vehicle state can be adjusted to prohibit driving, thereby ensuring the safety of the vehicle. In addition, if the power battery and the discharging gun are not successfully connected, the above-mentioned ways can also be used to output prompt information, and the connection state of the power battery and the discharging gun can be continuously monitored.

[0076] In an optional embodiment, after the power battery of the vehicle is successfully connected with the discharging gun, the method further comprises:

[0077] Step S110, control the power battery to supply power to the low-voltage system of the vehicle, so that the discharge authorization information is output through the vehicle machine interaction interface and / or the mobile intelligent device, and the vehicle is prohibited from driving.

[0078] It should be noted that in some application scenarios, the user uses the discharge function when the vehicle is parked, and the control system of the vehicle is in a dormant state. When the power battery management system of the vehicle detects that the power battery is successfully connected with the discharge gun, the power battery management system can network wake up the related controller (VCU) of the direct current discharge system of the vehicle, and the VCU controls the DCDC (Direct Current Direct Current) to start working and supply power to the low-voltage system of the vehicle. Correspondingly, the low-voltage system can include a vehicle machine system and a TBOX, and the vehicle machine system displays the discharge authorization information on the vehicle machine interaction interface, and the TBOX uploads the discharge authorization information to the cloud, and the cloud sends the discharge authorization information to the mobile intelligent device associated with the vehicle. Similarly, the vehicle controller also controls the vehicle to be in a prohibited driving state (i.e., the vehicle is prohibited from driving).

[0079] Step S20, in response to a first high-voltage discharge authorization operation of the user based on the discharge authorization information, control the power battery to high-voltage discharge to the intelligent discharge device connected with the discharge gun.

[0080] It should be noted that the user can obtain the discharge authorization information through the interaction interface of the vehicle machine and the mobile intelligent device, wherein the discharge authorization information includes whether to authorize the power battery to discharge externally, and the user can select yes or no. It can be understood that by setting the condition of authorizing the user to discharge the power battery, the safety of the discharge can be ensured, and the discharge is prevented from being started by mistake. The first high-voltage discharge authorization operation is an operation of the user selecting to authorize the power battery to discharge externally through the vehicle machine interaction interface or the mobile intelligent device for the first time in the current use scenario.

[0081] For example, in response to the first high-voltage discharge authorization operation of the user, the power battery is controlled to high-voltage discharge to the intelligent discharge device connected with the discharge gun. At this time, the intelligent discharge device enters a high-voltage standby state, and the intelligent discharge device turns on the external electrical load discharge switch and converts high-voltage direct current into alternating current. At this time, the external electrical load can be connected to the intelligent discharge device for normal use.

[0082] In a possible implementation, the step of controlling the power battery to high-voltage discharge to the intelligent discharge device connected with the discharge gun includes:

[0083] Step S210, control the power battery to low-voltage discharge to the intelligent discharge device for self-checking of the intelligent discharge device.

[0084] Step S220, after the self-checking of the smart discharging device is qualified and the electronic lock of the discharging gun is locked, controlling the high-voltage discharging of the power battery to the smart discharging device based on the power consumption parameter of the smart discharging device, wherein the power consumption parameter is obtained through the discharging handshake between the vehicle and the smart discharging device.

[0085] For example, to further ensure the safety during discharging, before controlling the high-voltage discharging of the power battery to the smart discharging device, the low-voltage discharging of the power battery to the smart discharging device is controlled first, and when there is low-voltage power supply, the smart discharging device can be self-checked. If the self-checking is qualified, the smart discharging device will also lock the electronic lock of the discharging gun to avoid taking out the discharging gun during discharging, which may cause safety hazards. After the self-checking is qualified and the electronic lock is locked, the high-voltage discharging of the power battery to the smart discharging device is controlled according to the power consumption parameter of the smart discharging device, wherein the power consumption parameter can include the rated working voltage, the current signal, the working voltage range, the maximum working current signal, etc. The power consumption parameter is obtained through the discharging handshake between the vehicle and the smart discharging device. For example, the smart discharging device and the vehicle can establish communication through the discharging handshake (i.e. discharging protocol), and then the smart discharging device sends the power consumption parameter to the vehicle.

[0086] In a possible implementation, after the step of controlling the high-voltage discharging of the power battery to the smart discharging device, the method comprises:

[0087] Step S30, outputting the discharging state of the power battery and the state information of the vehicle through the vehicle-machine interactive interface, the smart discharging device and / or the mobile smart device.

[0088] For example, after the power battery is discharged, the discharging state of the power battery and the state information of the vehicle related to the discharging can be output through the vehicle-machine interactive interface, the smart discharging device and / or the mobile smart device. The discharging state can include the discharging power, the discharging voltage, the discharging current, the discharging time, etc., and the state information of the vehicle can include the battery power of the vehicle and the prohibition of driving, etc. The process of outputting each state through the vehicle-machine interactive interface and the mobile smart device can refer to the process of outputting the discharging authorization information. In this embodiment, the smart discharging device can also be configured with a display screen, and the discharging state and the state information of the vehicle can also be output through the display screen. Therefore, the user can conveniently know the state parameters related to the discharging and the state information of the vehicle when the vehicle discharges to the outside.

[0089] In the embodiment, after the power battery of the vehicle is successfully connected with the discharge gun, discharge authorization information is output through the vehicle machine interactive interface of the vehicle and / or a mobile smart device associated with the vehicle; in response to a first high-voltage discharge authorization operation of a user based on the discharge authorization information, the power battery is controlled to high-voltage discharge to the smart discharge device connected with the discharge gun. That is, the application can provide multiple interactive ways for discharge authorization. On the one hand, the user can know that the vehicle is discharging when seeing the discharge authorization information. On the other hand, multiple ways for discharge control can be provided to the user, and the user can select a convenient control way to control the discharge process. Moreover, by setting the condition for user authorization of the discharge permission of the power battery, the safety of discharge can be ensured, and the misstart of discharge can be avoided. Thus, the overall use experience of the user is improved.

[0090] With reference to Figure 3 Based on the first embodiment of the application, the second embodiment of the application is proposed. In the embodiment, the same parts as the above embodiments can refer to the above content, which will not be described herein again. After the step of controlling the power battery to high-voltage discharge to the smart discharge device, the method comprises:

[0091] Step A10, in response to a high-voltage discharge authorization termination operation of the user, the power battery is stopped to high-voltage discharge to the smart discharge device;

[0092] For example, in response to the high-voltage discharge authorization termination operation of the user, taking the vehicle machine interactive picture as an example, the user can select a high-voltage discharge authorization termination option on the vehicle machine interactive picture, so that the power battery is stopped to high-voltage discharge to the smart discharge device.

[0093] Step A20, monitoring whether the high-voltage discharge authorization of the power battery is restored within a preset time period after the high-voltage discharge authorization termination operation;

[0094] For example, after the power battery is stopped to high-voltage discharge to the smart discharge device, the smart discharge device can unlock the electronic lock on the discharge gun, so as to facilitate the user to pull out the discharge gun and end the discharge. However, it should be noted that in some cases, the user may not necessarily pull out the discharge gun immediately after terminating the authorization, or it may not mean that the user will not continue to use the discharge function. Therefore, within a preset time period (such as 10 minutes) after the vehicle responds to the high-voltage discharge authorization termination operation, it is monitored whether the high-voltage discharge authorization of the power battery is restored, that is, whether the user reauthorizes the discharge of the power battery.

[0095] Step A30, if the high-voltage discharge authorization is not restored, the power battery is stopped to discharge to the low-voltage system of the vehicle;

[0096] For example, if the high-voltage discharge authorization is not resumed within a preset time period after the high-voltage discharge authorization termination operation, the power battery stops discharging to the low-voltage system of the vehicle, and the external discharge function of the power battery is completely terminated. It can be understood that after the user performs the high-voltage discharge authorization termination operation, the power battery will stop discharging to the low-voltage system of the vehicle after a delay (i.e., a preset time period). During this delay period, the user can choose to resume the high-voltage discharge authorization, thereby avoiding the need for the user to re-plug the discharge gun to trigger the discharge authorization operation interface. This improves the convenience of the user using the discharge function.

[0097] Step A40, if the high-voltage discharge authorization is resumed, return to the step of controlling the high-voltage discharge of the power battery to the intelligent discharge device, wherein the high-voltage discharge authorization is triggered to resume based on a second high-voltage discharge authorization operation of the user.

[0098] For example, if the high-voltage discharge authorization is resumed within a preset time period after the high-voltage discharge authorization termination operation, return to the step of controlling the high-voltage discharge of the power battery to the intelligent discharge device, wherein the high-voltage discharge authorization is triggered to resume based on a second high-voltage discharge authorization operation of the user. It should be noted that the difference between the second high-voltage discharge authorization operation and the first high-voltage discharge authorization operation is the time of the operation, i.e., the first high-voltage discharge authorization operation is the first high-voltage discharge authorization operation in the current application scenario. The second high-voltage discharge authorization operation is the high-voltage discharge authorization operation performed by the user after the termination of the discharge authorization operation.

[0099] In an available embodiment, the second high-voltage discharge authorization operation and the high-voltage discharge authorization termination operation are made by the user through the vehicle interaction interface, the mobile intelligent device, or the intelligent discharge device, wherein the high-voltage discharge authorization operation permission of the intelligent discharge device is opened based on the first high-voltage discharge authorization operation.

[0100] It should be noted that the first high-voltage discharge authorization operation can be made by the user through the vehicle interactive interface or the mobile intelligent device, and the second high-voltage discharge authorization operation can be made by the user through the vehicle interactive interface, the mobile intelligent device or the intelligent discharge device. Therefore, the second high-voltage discharge authorization operation has an additional operation approach of the intelligent discharge device relative to the first high-voltage discharge authorization operation. It can be understood that the vehicle interactive interface and the mobile intelligent device are more private interaction approaches relative to the intelligent discharge device. For example, the vehicle interactive interface needs to be entered into the vehicle, and the mobile intelligent device is a personal device of the user. When the vehicle is externally discharged, the intelligent discharge device is usually placed outside the vehicle and can be conveniently used by each user. Therefore, in order to ensure the safety of the use of the discharge function, only the high-voltage discharge authorization operation permission of the vehicle interactive interface and the intelligent discharge device is opened when the discharge function is used for the first time in the current use scenario, that is, the high-voltage discharge authorization operation cannot be made through the intelligent discharge device when the discharge function is used for the first time in the current use scenario, so as to avoid the discharge function of the vehicle being abused. After the user makes the first high-voltage discharge authorization operation, the high-voltage discharge authorization operation permission of the intelligent discharge device is triggered to be opened, that is, the user (including the vehicle owner himself) can conveniently complete the high-voltage discharge authorization operation through the intelligent discharge device placed outside without entering the vehicle or using the mobile intelligent device associated with the vehicle. For example, if the user is not the vehicle owner when going camping, it is not very convenient for the user to enter the vehicle or borrow the mobile phone of the vehicle owner. However, the high-voltage discharge authorization can be realized through the intelligent discharge device placed outside, which can greatly improve the user experience. Since the high-voltage discharge authorization operation permission of the intelligent discharge device is triggered to be opened after the user makes the first high-voltage discharge authorization operation, the discharge function can also be prevented from being abused, and the safety can be ensured.

[0101] Reference Figure 4 Based on the first embodiment and the second embodiment of the present application, the third embodiment of the present application is proposed. In the present embodiment, the same parts as the above embodiments can refer to the above content, and will not be described here.

[0102] After the step of controlling the power battery to high-voltage discharge to the intelligent discharge device connected with the discharge gun, the method further comprises:

[0103] Step B10, monitoring the power of the power battery;

[0104] Step B20, if the power reaches a first power threshold, outputting a first prompt information, wherein the first power threshold is determined based on the distance between the location of the vehicle and the preset return destination;

[0105] Step B30, outputting second prompt information if the electric quantity reaches a second electric quantity threshold, wherein the second electric quantity threshold is determined based on the distance between the location of the vehicle and the current nearest charging station.

[0106] For example, after the step of controlling the power battery to discharge high voltage to the intelligent discharge device, the vehicle also monitors the electric quantity of the power battery in real time, and outputs corresponding prompt information if a preset electric quantity threshold is reached. It should be noted that in the present embodiment, there are two preset electric quantity thresholds, one of which is a first electric quantity threshold, and the other of which is a second electric quantity threshold. The first electric quantity threshold is determined based on the distance between the location of the vehicle and the preset return destination. For example, the electric energy consumed for traveling from the location to the preset return destination can be taken as the first electric quantity threshold, or the consumed electric energy plus a preset surplus electric quantity can be taken as the first electric quantity threshold. Similarly, the second electric quantity threshold is determined based on the distance between the location of the vehicle and the current nearest charging station. For example, the electric energy consumed for traveling from the location to the preset return destination can be taken as the second electric quantity threshold, or the consumed electric energy plus a preset surplus electric quantity can be taken as the second electric quantity threshold.

[0107] It can be understood that in the present embodiment, the remaining electric quantity of the power battery can be detected when the power battery is discharging, and the user is prompted after the preset threshold is reached, thereby prompting the future travel plan of the user.
