The present specification provides method operational steps as described in the examples or flowcharts, but may include more or fewer operational steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution. As shown in fig. 4, the method may include:
s101: the vehicle-end communication controller monitors voltage signals at two ends of the resistor by using the first resistor signal detection module.
Specifically, the vehicle-end communication controller receives a resistance signal sent by the charging gun through the socket, wherein the resistance signal is a signal input by the charging gun through the PP terminal of the socket, and the resistance signal represents the connection state of the charging gun and the charging pile and the overload capacity of the charging gun. Because the resistance in the charging gun is different in resistance value when being connected with different charging piles, the transmitted resistance signal acts on the resistance, so that the voltage at two ends of the resistance is changed. The vehicle-end communication controller can monitor voltage signals at two ends of the resistor through the PP terminal of the socket, and can monitor charge and discharge control signals through the CP terminal of the socket.
The terminals of the socket in the present application may include PP, CP, L1, L2, L3, N, DC +, DC-, PE. The PP is a resistance signal, the resistance signal represents the connection state of the charging gun and the charging pile and the overload capacity of the charging gun, the resistance signals are different when the charging gun and the charging pile are well connected and the connection state is poor, the power of the charging gun is not higher than rated power and the resistance signals are different when the power of the charging gun is higher than the rated power, the signals (charging and discharging control signals) received by the CP terminal are pulse width modulation signals, the L1, L2, L3 and N terminals provide alternating current, the DC+ and DC-terminals provide high-voltage direct current, and the PE terminal provides vehicle ground for safety protection.
S103: and the vehicle end communication controller determines to enter a discharging mode according to the voltage signals at two ends of the resistor.

The vehicle-mounted charger can be set to be in a dormant state, and when the vehicle-end communication controller confirms that the vehicle-end communication controller enters a discharging mode, the vehicle-end communication controller sends wake-up information to the vehicle-mounted charger so as to wake up the vehicle-mounted charger.

Specifically, since the voltage signals at the two ends of the resistor and the discharge control signal may be signals of different area standards, the vehicle-mounted charger may not be able to directly process the voltage signals at the two ends of the resistor and the discharge control signal. For example, the resistor voltage signal and the discharge control signal may be signals conforming to a first standard of the first region, signals conforming to a second standard of the first region, or signals conforming to a second standard of the second region. The vehicle-mounted charger may only recognize signals meeting the second standard of the first area and the second area, but cannot recognize signals meeting the first standard of the first area, and the vehicle-end communication controller may simulate a target resistance signal which the vehicle-mounted charger can recognize and process by using the resistance signal transmitting module and transmit the target resistance signal to the vehicle-mounted charger; the first control signal transmitting module can be utilized to simulate the target discharge control signal and transmit the target discharge control signal to the vehicle-mounted charger, so that the compatibility of the vehicle-mounted charger to signals is improved.
S107: the vehicle-mounted charger acquires a discharge type signal sent by the vehicle controller.
Specifically, the discharge type signal is a signal sent to the vehicle-mounted charger by the vehicle controller. In some embodiments, a selection manner of the discharge type signal may be preset on the vehicle terminal for the user to select. Or the vehicle and the user terminal perform data interaction, and the whole vehicle controller receives the discharge type signal sent by the user terminal. A discharge type signal confirmation knob, a key, a shift, etc. may be provided in the vehicle to allow the user to select the discharge type signal.
S109: the vehicle-mounted charger acquires a target resistance signal by using a second resistance signal detection module, and acquires a target discharge control signal by using a second control signal detection module.
S111: and the vehicle-mounted charger determines the target type of the discharge mode according to the target resistance signal, the target discharge control signal and the discharge type signal.
Specifically, the vehicle-mounted charger carries out rechecking according to the target resistance signal and the target discharge control signal, and confirms to discharge outwards according to the target resistance signal and the target discharge control signal. And then confirming the target type of the discharge mode according to the discharge type signal.
S113: and the vehicle-mounted charger controls a signal interaction mode corresponding to the target type of the discharging mode of the second control signal sending module to the load according to the target type of the discharging mode so as to control the load to be charged.
Before the vehicle-mounted charger discharges the load, the vehicle-mounted charger can interact with the load in advance to confirm that the load is charged. Before charging different loads, the information interaction mode with the vehicle-mounted charger is different. The vehicle-mounted charger can control the second control signal sending module to carry out a signal interaction mode corresponding to the target type of the discharging mode to the load according to the target type of the discharging mode so as to control the load to be charged.

In some embodiments, as shown in fig. 5, step S113: the controlling, by the vehicle-mounted charger, the second control signal sending module to perform, to the load, a signal interaction manner corresponding to the target type of the discharging mode according to the target type of the discharging mode, so as to control charging of the load may include:
s1111: and when the target type of the discharging mode of the vehicle-mounted charger is that the household appliance is discharged, the household appliance is discharged.
Specifically, the home appliance may be a home appliance such as a cellular phone, a car refrigerator, a fan, or the like. And when the target type of the discharging mode is the household appliance, the vehicle-mounted charger discharges the household appliance.
S1113: when the target type of the discharging mode is that the target vehicle is discharged, the vehicle-mounted charger utilizes the second control signal transmitting module to transmit a first target discharging signal to the target vehicle so as to carry out discharging confirmation with the target vehicle and discharge the target vehicle.
Specifically, the first target discharge signal may be a CP PWM (Pulse Width Modulation ) signal of a first preset duty cycle, and the target vehicle may perform signal confirmation before charging according to the CP signal of the first preset duty cycle when charging. When the target type of the discharge mode is to discharge the target vehicle, a first target discharge signal is sent to the target vehicle to confirm the discharge with the target vehicle, and the target vehicle is discharged.

s201: and the vehicle-end communication controller determines to enter a charging mode according to the voltage signals at two ends of the resistor.
Specifically, the vehicle-end communication controller receives the resistance signal sent by the charging gun through the socket, and can preset the voltage values at two ends of the resistance as a basis for judging whether to charge and discharge, for example, when the vehicle-end communication controller monitors that the voltage values at two ends of the resistance in the resistance signal are b, d and f, the vehicle-end communication controller determines to enter a charging mode.
S203: the vehicle-end communication controller controls the first control switch to be closed, controls the second control switch to be opened, monitors the charging control signal by using the first control signal detection module, and determines the type of the charging and discharging control signal.
Specifically, when it is determined to enter the charging mode, the types of the charging control signals may include a first type of charging control signal and a second type of charging control signal.

The first type charge control signal characterizes a first portion of signals corresponding to the first region standard, and the second type charge control signal characterizes a second portion of signals corresponding to the first region standard and signals corresponding to the second region standard.
