The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

An external discharge method of a rescue vehicle according to an embodiment of the present invention is described below with reference to fig. 1 to 3.

As shown in fig. 1 to 3, the method for discharging electricity to the outside of a rescue vehicle according to an embodiment of the present invention includes the steps of: and receiving a power utilization request instruction. The destination distance and the driving time are obtained, and the duration of the rescue vehicle in the charging mode during driving is adjusted. And when the vehicle reaches the position of the vehicle to be charged, setting the lowest driving mileage reservation and the lowest discharging SOC setting, and controlling the rescue vehicle to discharge so as to charge the vehicle to be charged. Note that the SOC value is a battery state of charge.

Further, as shown in fig. 1, before receiving the power demand instruction: the rescue vehicle receives the demand signal sent by the network platform and sends prompt information to allow a user to select whether to receive the command. Specifically, the rescue vehicle monitors rescue signals of nearby vehicles to be charged in real time through the network platform, a demand signal is transmitted to a multimedia host of the vehicle through a remote vehicle-mounted terminal, the multimedia host pops up windows to prompt whether the vehicles go to rescue, a user of the rescue vehicle selects whether the vehicles go to according to the conditions of the vehicles and the user, if the user selects not, the pops up windows to prompt to disappear, and the multimedia host transmits the signals to the vehicle control unit if the user selects yes. It should be understood that the method for receiving the rescue task is not limited to this, and for example, the network platform may also perform analysis according to the position of the rescue vehicle, whether there is a rescue task, and the like, and designate the most suitable rescue vehicle to go to rescue.

Further, after the destination distance and the time required for driving are obtained, the duration of the charging mode is adjusted according to the SOC value of the battery of the current rescue vehicle and the hundred kilometers of energy consumption. Specifically, after the user selects forward and backward, the multimedia host sends a relevant signal to the vehicle control unit, the vehicle control unit intelligently switches the running mode of the rescue vehicle according to the destination distance and the driving time, for example, when the SOC of the power battery is low, the vehicle control unit selects a driving charging mode, the motor is driven in the mode, the motor executes negative torque to charge the power battery, the high SOC state of the power battery is ensured when the rescue vehicle reaches the position of the vehicle to be charged while the engine runs in an economic area, and the preparation for discharging can be made.

As shown in fig. 2, in some embodiments of the invention, after setting the minimum driving range reservation and the minimum discharging SOC setting, it is determined whether the current SOC amount is higher than the minimum discharging SOC amount, and it is determined whether the driving range can satisfy the minimum driving range reservation. And if the current SOC amount is higher than the lowest discharge SOC amount and the endurance mileage meets the lowest endurance mileage reservation, controlling the rescue vehicle to discharge. And if the current SOC amount is lower than the lowest discharge SOC amount and/or the endurance mileage does not meet the lowest endurance mileage reservation, sending out prompt information. Specifically, before external discharge, the minimum driving mileage reservation and the minimum discharge SOC are set according to the self condition, so as to ensure the electric quantity and driving of the rescue vehicle, and as long as one of the minimum driving mileage reservation and the minimum discharge SOC is lower than a set value, a condition that the rescue vehicle cannot return may exist, and a prompt message is sent to remind a user of the rescue vehicle.

Further, the prompt information is whether parking charging is selected, and if the parking charging is selected, the rescue vehicle is controlled to discharge. Specifically, after parking charge is selected, the engine charges the battery until the SOC is full or manually stopped. It is of course understood that the rescue vehicle may discharge the vehicle to be charged while parking for charging.

As shown in fig. 2, in some embodiments of the present invention, after the current SOC amount is higher than the lowest discharging SOC amount and the mileage meets the lowest mileage reservation, it is determined whether the discharging requirement is met, if yes, the rescue vehicle is controlled to discharge, and if not, a warning message is sent. Specifically, in addition to meeting the condition that the current SOC is higher than the minimum discharge SOC and the mileage meets the minimum mileage reservation, the vehicle controller of the rescue vehicle also needs to check the high-voltage state of the vehicle, confirm that no discharge prohibition fault exists, and ensure high-voltage safety, otherwise, stop discharging, for example, rapidly stop discharging when the temperature of the battery is too high. When the conditions are met, the vehicle control unit sends discharge permission information to the bidirectional inverter, and the bidirectional inverter controls the vehicle to discharge. Wherein the reminder information may include a reminder of where the condition is not satisfied, such as a reminder that the battery does not satisfy the condition.

As shown in fig. 3, in some embodiments of the present invention, after the rescue vehicle is controlled to discharge, charging information is synchronized to the mobile terminal of the user. Specifically, after the rescue vehicle discharges, the rescue vehicle synchronizes charging information to the mobile terminal of the user, and the connection manner between the mobile terminal and the vehicle may be that the multimedia host is connected with the mobile phone APP through bluetooth, although it is understood that the connection manner between the mobile terminal and the vehicle is not limited thereto, for example, through a network connection. Thereby enabling the user to monitor the charging information in real time.

Further, after the charging information is synchronized to the mobile terminal of the user, a control instruction sent by the user based on the mobile terminal is received, and the discharging condition is adjusted according to the control instruction. Specifically, the mobile terminal of the user can send an instruction to the rescue vehicle to adjust the discharging condition, for example, the user mobile phone APP controls the rescue vehicle to stop discharging, in addition to receiving the charging information. Therefore, the user can change the discharge condition in real time without waiting on the vehicle.

Further, the control instruction sent by the user based on the mobile terminal includes: the discharge time is changed and the discharge command is interrupted. Specifically, a user changes discharge information or interrupts discharge on the mobile phone APP, the multimedia host computer synchronizes signals, and transmits the signals to the vehicle control unit according to the setting of the user, and the vehicle control unit sends signals to the bidirectional inverter according to the setting of the user and the safety condition of the vehicle to control the discharge of the vehicle. It is of course understood that the control instructions are not limited thereto, such as changing the amount of discharged power. Therefore, the user can change the lower limit value of the discharge or terminate the discharge in real time without waiting on the vehicle.
