when the external power supply 01 can supply power, the switch unit 02 is used for connecting the external power supply 01 into a circuit, and the external power supply 01, the switch unit 02, the voltage transformation module 04, the motor controller 06 and the electric equipment 05 form a first discharge circuit;
when the external power supply 01 cannot supply power, the switch unit 02 is used for connecting the energy storage module 03 into a circuit, and the energy storage module 03, the switch unit 02, the voltage transformation module 04, the motor controller 06 and the electric equipment 05 form a second discharge circuit;
the voltage transformation module 04 is configured to convert the voltage of the external power supply 01 or the voltage of the energy storage module 03 into the working voltages of the motor controller 06 and the electric device 05. This vary voltage module 04 is for motor controller 06 reaches consumer 05 supplies power, and when vary voltage module 04 does not have voltage output, this motor controller 06 can't work.
The external power supply 01 may be a battery of the entire vehicle, the rated voltage of the battery is 12V, and the external power supply 01 provides the motor controller 06 with a working voltage of 12V. The voltage transformation module 04 can convert the 12V voltage output by the storage battery into 5V, 3.3V, etc., and can also directly output the 12V voltage to supply power to the electric equipment 05 to drive the motor controller 06 and the electric equipment 05 to work. Further, the negative electrode of the external power supply 01 is connected to the ground of the entire chassis, and the ground of the motor controller 06 and the ground of the electric equipment 05 controlled by the motor controller 06 are also connected to the entire chassis, thereby forming a complete loop.
In one embodiment, the powered device 05 includes, but is not limited to, sensors, IGBT (Insulated Gate Bipolar Transistor) modules, and other components controlled by the machine controller 06.

One usage scenario according to the present embodiment is for example:
after collision, the whole vehicle needs to be protected by high-voltage electricity in an emergency, or a high-voltage component is seriously out of control, ignited and smokes, or the whole vehicle detects insulation failure, for example, a short circuit is detected between a high-voltage positive electrode and a vehicle body, and when a wire harness is damaged, the whole vehicle strategy protection, such as power reduction of the whole vehicle, or all high-voltage electric equipment is closed, and meanwhile, a high-voltage relay is cut off so as to cut off the high-voltage supply of the whole. However, in some cases of the above emergency high voltage, when the high voltage relay is quickly cut off, a large amount of electric energy still remains on the high voltage bus, and meanwhile, the high voltage device has many devices such as capacitors, and also stores a large amount of electric energy, and there is no specific discharging circuit that can not quickly consume the electric energy on the capacitor, so that the electric energy needs to be released through a discharging circuit, which hastens the initiative discharging. Of course, if there is no active discharge, the residual electric energy on the high voltage bus can be slowly released over time, which is called passive discharge. Passive discharge takes much longer to release the residual electrical energy below the human body safety value than active discharge. The principle of active discharge is that the motor controller 06 controls the IGBT module to form a loop with the entire vehicle high-voltage direct current and the electric equipment, so that the entire vehicle bus electric energy is quickly consumed, and the purpose of releasing the entire vehicle bus electric energy is achieved.
When the whole vehicle needs to be powered off at high voltage, if the external power supply 01 supplies power normally, the external power supply 01 supplies power to the motor controller 06, and when unexpected power failure (such as unexpected failure of a 12V low-voltage storage battery and a direct-current converter caused by a collision accident) occurs in the external power supply 01, the energy storage module 03 relays to supply power to the motor controller 06, so that the motor controller 06 can still work for a period of time effectively, and the length of the time for which the motor controller 06 can work continuously is determined according to the active discharge duration requirement.

Optionally, the active discharge device 100 of the vehicle further includes an electronic component 07 for controlling unidirectional current flow, where the electronic component 07 is disposed between the external power supply 01 and a node connected to the energy storage module 03;
the electronic component 07 is configured to control a current in the circuit to flow from the energy storage module 03 to the transformation module 04 when the external power source 01 cannot supply power.
The electronic component 07 prevents the current in the energy storage module 03 from flowing back to other components of the entire vehicle when the external power supply 01 is no longer supplied with power and the energy storage module 03 supplies power in a relay manner, so that the current of the energy storage module 03 flows to the transformation module 04, and the transformation module 04 transmits the converted voltage to the motor controller 06.
As shown in fig. 5, the electronic component 07 includes a diode, an anode of the diode is connected to an anode of the external power supply 01, and a cathode of the diode is connected to a node connected to the energy storage module 03.
When the external power supply 01 of the 12V storage battery supplies power abnormally, the diode can prevent the current in the energy storage module 03 from flowing back to the external power supply 01, so that the current in the energy storage module 03 can only flow to the motor controller 06.
As shown in fig. 6, the electronic component 07 includes a first relay, a coil of the first relay is connected to the external power supply 01, a normally open contact of the first relay is connected to a node connected to the energy storage module 03, one end of an armature of the first relay is connected to the positive electrode of the external power supply 01, and when the coil of the first relay is energized, the other end of the armature of the first relay is conducted to the normally open contact.
When the external power supply of the 12V storage battery is normal, the first relay is closed to turn on the loop, and when the external power supply of the 12V storage battery is abnormal, the first relay cannot be maintained to be closed to be disconnected, so that the external power supply of the 12V storage battery is not connected with the energy storage module 03, and the current of the energy storage module 03 is prevented from flowing to other elements of the motor controller 06.
In one embodiment, the electric device 05 includes a motor, and the motor is respectively connected to the motor controller 06 and the voltage transformation module 04.
In one embodiment, the switch unit 02 includes a second relay, a coil of the second relay is connected to the external power supply 01, one end of an armature of the second relay is connected to the transformation module 04, a normally open contact of the second relay is connected to the external power supply 01, and a normally closed contact of the second relay is connected to the energy storage module 03;
when the coil of the second relay is electrified, the other end of the armature of the second relay is conducted with the normally open contact;
when the coil of the second relay is powered off, the other end of the armature of the second relay is conducted with the normally closed contact.
As shown in fig. 5, when the external power supply 01 is normally supplied with power, the coil of the second relay is energized. The armature of the second relay is attracted, so that the other end of the armature is in contact conduction with the normally open contact 02-1, an external power supply 01 is connected into a circuit to form a first discharge circuit, when the external power supply 01 cannot continue to supply power, the coil of the second relay is powered off, the attraction is lost, so that the other end of the armature is in contact conduction with the normally closed contact 02-2, and the energy storage module 03 is connected into the circuit to form a second discharge circuit.
In one embodiment, as shown in fig. 4, the energy storage module 03 includes a battery, a negative electrode of the battery is connected to a negative electrode of the external power supply 01, and a positive electrode of the battery is connected to the normally closed contact of the second relay.
Optionally, the rated voltage of the battery is the same as the rated voltage of the external power supply 01, and the rated voltage of the battery is 12 volts.
In one embodiment, as shown in fig. 5 and 6, the energy storage module 03 includes a capacitor, one end of the capacitor is connected to the negative electrode of the external power supply 01, and the other end of the capacitor is connected to the normally closed contact of the second relay and the positive electrode of the external power supply 01.
When the external power supply 01 of the whole vehicle 12V is supplied normally, the external power supply 01 charges the energy storage module 03, and when high voltage is needed and the external power supply 01 cannot work due to accidents or the power supply is cut off, the capacitor continues to supply power to the motor controller 06.
The negative electrode of the external power supply 01 and the ground wire of the motor controller 06 are both connected with the chassis of the whole vehicle to form a complete loop, and the negative electrode of the energy storage module 03 and the ground wire of the motor controller 06 are directly connected inside the motor controller 06 to form a discharge loop.
One usage scenario according to the present embodiment is for example:
when the vehicle is triggered by collision, a high-voltage component is seriously failed, a high-voltage power storage battery is abnormally cut off or a high-voltage relay is cut off in an emergency, a high-voltage loop is cut off, and the like, which require high-voltage electricity of a vehicle high-voltage bus in an emergency, the motor controller receives instructions of components such as a vehicle controller and the like to carry out active discharging so as to consume residual electric energy of the high-voltage bus. When the external power supply supplies power to the motor controller abnormally, the energy storage module supplies power to the motor controller in a relay mode. Among them, there are many ways for the motor controller to know that the external power supply is abnormal, for example: the motor controller is provided with a signal sampling line, and the level condition of a power supply loop of an external power supply of the 12V storage battery is detected through the signal sampling line so as to know whether the power supply of the external power supply of the 12V storage battery is abnormal or not; when the power supply is abnormal, some components cannot send CAN signals to the motor controller, the CAN communication of the received components of the whole vehicle CAN be judged, and the power supply abnormality of an external power supply CAN be judged if the CAN signals are lost in a large area; if a power supply manager or an equivalent component is arranged on the whole vehicle, whether the external power supply is abnormal or not CAN be obtained by receiving a CAN or level signal of the power supply manager.
Since the low voltage power supply port abnormality does not represent a high voltage port abnormality, the high voltage harness and the high voltage port are not necessarily damaged in case of a collision. The active discharge of the motor controller 06 also guarantees a low-voltage safety threshold for the residual electric energy of other high-voltage components to a certain extent.
The motor controller 06 generally accounts for the vast majority of the power consumption of all the electric devices of the whole vehicle, and the power consumption of the motor controller 06 is estimated to be more than 90% of the whole vehicle, so that if the motor controller can reduce the residual electric energy to be below a safety threshold, the high-voltage safety of the whole vehicle can be ensured to a great extent. For example, when a collision accident cuts off a high-voltage connection port of the motor system and the whole vehicle to cut off the high-voltage connection between the motor system and the whole vehicle, and when the high-voltage relay is disconnected, other high-voltage equipment of the whole vehicle can quickly reduce the residual electric energy of the high-voltage components to be below a safety threshold value through passive discharge. The motor controller accounts for the most of the power consumption of all electric equipment of the whole vehicle, the capacitance of a working circuit in the motor controller is large, and the electric energy stored in the motor controller during normal work is far more than that of other high-voltage components, so that the speed of the residual electric energy of a high-voltage bus of the whole vehicle consumed by the passive discharge of other high-voltage electric equipment is far faster than that of the residual electric energy consumed by the high-voltage bus of the whole vehicle connected with a motor system.
