As shown in fig. 1, an application scenario schematic diagram of a vehicle discharge control method provided in an embodiment of the present application includes a discharge device, an electric device, and an electric vehicle, where the electric vehicle is connected with the discharge device, and the discharge device is connected with the electric device.

The discharging equipment is used for outputting the electric quantity stored in the battery of the electric vehicle to the electric equipment. The discharging equipment comprises a discharging gun, a cable and a power strip, wherein the discharging gun is connected with the power strip through the cable and is used for being connected with a discharging interface of an electric vehicle, and the power strip is connected with electric equipment.

Fig. 3 is a flowchart showing a control method of vehicle discharge according to an exemplary embodiment, and as shown in fig. 3, the control method of vehicle discharge includes the steps of:

and S301, in response to the fact that the connection time of the discharge gun and the discharge interface exceeds the preset time, discharging is conducted to the electric equipment through the discharge equipment.

In one possible implementation, the electric vehicle is connected to the discharge device in response to insertion of the discharge gun into a discharge interface of the electric vehicle. If the connection time of the electric vehicle and the discharging equipment exceeds the preset time, the electric vehicle generates a discharging requirement, and a vehicle discharging control system judges whether the electric vehicle meets the preset discharging condition according to the requirement.

Specifically, if the electric vehicle is in a parking state, the voltage of the electric vehicle exceeds a preset voltage, the discharge power of the battery of the electric vehicle exceeds a preset value, and the residual electric quantity of the battery of the electric vehicle exceeds a preset value, the electric vehicle is indicated to meet a preset discharge condition, and a vehicle discharge control system converts direct current stored in a power battery of the electric vehicle into alternating current and discharges the alternating current through a discharge device.

In an example, when the gear of the electric vehicle is in the "P" gear, the voltage of the electric vehicle is 400v, the preset voltage is 350v,400v is greater than 300v, the discharge power of the electric vehicle battery is 6kw, the preset discharge power is 3kw, and the residual electric quantity of the electric vehicle battery exceeds 10kwh, the electric vehicle battery can be discharged through the discharging device.

If the electric vehicle is not in a parking state, the voltage of the electric vehicle does not exceed the preset voltage, the discharge power of the electric vehicle battery does not exceed the preset value, the residual electric quantity of the electric vehicle battery does not exceed the preset value, the electric vehicle is not satisfied with the preset discharge condition, and the discharge is forbidden.

In one example, when the gear of the electric vehicle is not in the "P" gear, the voltage of the electric vehicle is 300v, the preset voltage is 350v,300v <400v, the discharge power of the electric vehicle battery is 2kw, the preset discharge power is 3kw,2kw <3kw, and the remaining power of the electric vehicle battery does not exceed 10kwh, the discharge is prohibited.

S302, detecting the distance between a key of the electric vehicle and the electric vehicle, the door state of the electric vehicle and the temperature of a discharge interface in the process of discharging the electric vehicle.

The distance between the key of the electric vehicle and the electric vehicle refers to a straight line distance between the key of the electric vehicle and the electric vehicle after the user leaves the electric vehicle with the key. The door states of the electric vehicle may include an open state and a closed state. The temperature of the discharge interface refers to the temperature at which the discharge device is connected to the electric vehicle.

In an example, in the process of discharging the vehicle, the control system for discharging the vehicle can measure the distance between the key and the electric vehicle in real time by receiving signal data sent by the key of the vehicle, for example, the key of the electric vehicle is provided with a Bluetooth module, and the key of the electric vehicle can be in communication connection with the electric vehicle through the Bluetooth module. Further, the electric vehicle key may further be provided with a positioning module (such as a GPS chip), so that the electric vehicle key may acquire current position information based on the positioning module, and send the position information to the electric vehicle through the bluetooth module. The electric vehicle may determine a distance between the electric vehicle key and the electric vehicle based on the position information of the key and the position information of the electric vehicle. And a Bluetooth module is arranged between the Bluetooth module and the electric vehicle to acquire signal data. The vehicle may also detect a temperature of a location where the discharge device is connected to the electric vehicle through a vehicle temperature sensor, and determine a door state of the electric vehicle through an electric vehicle door sensor.

And S303, stopping discharging to the electric equipment if the temperature of the discharge interface exceeds the preset temperature.

In one example, the control system for vehicle discharge controls the electric vehicle to discharge according to the temperature of the discharge interface detected in S302. If a user uses high-power electric equipment, the temperature of the discharge interface is increased. And the control system for discharging the vehicle stops discharging to the electric equipment when detecting that the temperature of the discharging interface exceeds the preset temperature. For example, the preset temperature may be 60 ℃, and when the temperature is 70 ℃, the discharge to the powered device is stopped.

In another example, a control system for vehicle discharge may dynamically adjust the output power at discharge by detecting the temperature of the discharge interface in real time. For example, when the discharge interface temperature is too high, the output power during discharge is reduced, and each time the discharge temperature is increased by 10 ℃, the output power is reduced by 1kw.

And S304, if the temperature of the discharge interface does not exceed the preset temperature, and the electric vehicle door is in a closed state and the distance between the electric vehicle and the electric vehicle key exceeds the preset distance in the preset time period, stopping discharging to the electric equipment.

In one possible implementation, when the control system of the vehicle discharge detects that the temperature of the discharge interface does not exceed the preset temperature, the control system indicates that the electric vehicle is in a normal discharge process. In the process, the control system of the vehicle discharging in the preset time period detects that the vehicle door is in a closed state and the distance between the key of the electric vehicle and the electric vehicle exceeds a preset range, and the fact that the user leaves the vehicle for a long time when the electric vehicle is normally discharged is indicated, and then the discharging to the electric equipment is stopped.

In one example, when the temperature of the discharge interface is below 60 ℃, and the control system of the vehicle discharge detects that the vehicle door is in a closed state and the distance between the key of the electric vehicle and the electric vehicle exceeds the preset range by 50 meters, the electric device stops discharging.

Based on the method shown in fig. 3, the embodiment of the application provides a method for controlling vehicle discharge, which can be applied to an electric vehicle, wherein the electric vehicle is provided with a discharge device, the discharge device comprises a discharge gun and a power strip, the discharge gun is connected with the power strip through a cable, the discharge gun is connected with a discharge interface of the electric vehicle, and the power strip is connected with electric equipment. In response to the connection time of the discharge gun and the discharge interface exceeding the preset time, discharging the electric equipment through the discharge equipment; detecting the distance between a key of the electric vehicle and the electric vehicle, the door state of the electric vehicle and the temperature of a discharge interface in the process of discharging the electric vehicle; if the temperature of the discharge interface exceeds the preset temperature, stopping discharging to the electric equipment; if the temperature of the discharge interface does not exceed the preset temperature, in a preset time period, the electric vehicle door is in a closed state, and the distance between the electric vehicle and a key of the electric vehicle exceeds the preset distance, stopping discharging to the electric equipment. The method provided by the embodiment of the application can control the electric vehicle discharging process by detecting the position information of the electric vehicle door and the electric vehicle key and the temperature of the discharging interface, and can effectively prevent safety accidents caused by overhigh temperature of electric vehicle components and long-time departure of a user from the electric vehicle.

In some embodiments, as shown in fig. 4, a method for controlling vehicle discharge provided in the embodiments of the present application further includes the following steps:

s401, outputting discharge information of the electric vehicle during the discharge of the electric vehicle.

The discharging information comprises the remaining capacity of the battery of the electric vehicle, the temperature of a discharging interface of the electric vehicle and the discharging power of the electric vehicle.

In one possible implementation manner, when the vehicle discharge control system identifies the discharge requirement outside the vehicle, whether the current state of the vehicle meets the preset discharge condition is judged, and when the vehicle meets the preset discharge condition, the electric vehicle is controlled to discharge. And meanwhile, the discharge starting information of the electric vehicle is displayed to a user through the instrument. For example, the displayed information may include electric vehicle battery available power, electric vehicle battery remaining power, discharge device connection status, discharge interface temperature, and the like.

If the electric vehicle satisfies the preset discharging condition, the electric vehicle meter may display that the electric vehicle can perform normal discharging. If the electric vehicle does not meet the preset discharge condition, the electric vehicle can prompt a user that the electric vehicle is prohibited from discharging, and the specific reason for prohibiting the discharging is displayed on the instrument. For example, if the electric vehicle is not in a parked state, the meter displays "vehicle is not parked, discharge is prohibited outside the vehicle", and the user is alerted in a voice broadcast manner.

S402, when the electric vehicle stops discharging, outputting a cause of stopping discharging the electric vehicle.

In a possible implementation manner, if the electric vehicle stops discharging during normal discharging, the control system of vehicle discharging detects the electric vehicle, identifies a specific cause of stopping discharging, and displays a cause corresponding to stopping discharging.

In one example, when the power of the electric equipment is high, and the temperature of the discharge interface is high, the electric vehicle stops discharging, and when the vehicle instrument displays that the temperature of the discharge interface is too high, the discharge is stopped, and when the temperature of the discharge interface is reduced to a safe temperature, a user is reminded of discharging again.

In yet another example, if during the discharging, the control system of the vehicle discharging recognizes that the electric vehicle door is in a closed state and the distance between the electric vehicle key and the electric vehicle exceeds a preset distance, then "the user exceeds a safe distance, and the discharging is stopped" is displayed on the meter. Meanwhile, the control system of vehicle discharge sends prompt information to the user terminal to prompt the user to return as soon as possible. For example, the control system of the vehicle discharge reminds the user in a short message manner, such as "the user leaves the vehicle for a long time and please return as soon as possible".

Based on the method shown in fig. 4, the embodiment of the application can display the discharge process outside the vehicle to the user through the instrument, so that the user can more intuitively control the discharge process. The reason for failure in starting the discharge outside the vehicle is prompted to the user, so that the user can more easily check the reason that the discharge cannot be started. Through detecting vehicle door lock state and key position information, send prompt message to the user when leaving the vehicle for a long time after the user opens the outside discharge, prevent the risk that the electrical apparatus and the rifle of discharging lose. According to the embodiment of the application, the discharge process outside the vehicle can be displayed to the user through the instrument, so that the user can more intuitively control the discharge process, the user can be prompted of the reason of failure in opening the discharge outside the vehicle, and the user can more easily check the reason that the discharge cannot be opened.
