The content of the invention
Goal of the invention of the present utility model is to overcome the shortcomings of in prior art, and it is high voltage-controlled to provide a kind of pure electric vehicle
Device preliminary filling control module processed, improves the response speed of vehicle high-pressure system, reduces high pressure risk, extends the service life of vehicle.
The technical solution of the utility model is：Including the micro-control being connected respectively with CAN, firing key, power taking switch
Unit processed, the first input end of the micro-control unit connects through high_voltage isolation circuit one and main contactor front voltage Acquisition Circuit
Connect, the second input of the micro-control unit is connected through high_voltage isolation circuit two with main contactor rear end voltage collection circuit；
First output end of the micro-control unit connects main contactor, the second of the micro-control unit through main contactor drive circuit
Output end connects preliminary filling contactor through preliminary filling contactor drive circuit.
The micro-control unit, high_voltage isolation circuit one, high_voltage isolation circuit two, main contactor drive circuit, preliminary filling connect
Tentaculum drive circuit composition preliminary filling control integration module.
The 3rd input connection firing key of the micro-control unit, the 4th input connection of the micro-control unit
Power taking is switched.
Preliminary filling control integration module in the high-voltage combination controller that the utility model is improved, its micro control unit is except connecing
Receive vehicle CAN on battery and electric machine controller two ends voltage outside, also by high-voltage acquisition circuit, voluntarily gather battery and
The voltage at electric machine controller two ends, and analysis is calculated by the voltage that different modes are obtained to both, in every electricity
Pressure value meets on main contactor in the case of electric standard, just controls the adhesive of preliminary filling contactor and main contactor.This control
Method not only protects the safety of each component on main preliminary filling loop, also effectively prevent because key componentses damage make it is whole
The car lost of life and the increased problem of after cost.This kind of working method, improves the accuracy and height of each voltage data collection
The security of electricity, is fundamentally continued the service life of vehicle in pressure.The utility model solves problems with：From whole
The voltage at battery and electric machine controller two ends is received in car CAN, when each voltage meets power up requirement, is directly controlled pre-
The adhesive of contactor and main contactor is filled, but main contact is easily caused in the case of vehicle CAN communication abnormality or mistake
The adhesion or failure of device contact, cannot be guaranteed the traffic safety of vehicle.
The utility model completes the control to main contactor working method by outside Acquisition Circuit and internal control circuit
System, prevents main contactor from contact adhesion or failure occur, reduces high pressure failure risk, it is ensured that the safety of vehicle operation and smooth
It is logical.Preliminary filling control integration module is the critical component inside high-voltage combination controller, and it not only controls high-voltage combination controller
The adhesive of internal direct current contactor and disconnection, also improve the response speed of vehicle high-pressure system, reduce high pressure risk, extend
The service life of vehicle.
Additionally, the utility model also add to main contactor in addition to carrying out upper and lower electric control to master, preliminary filling contactor
Defencive function.Preliminary filling controls integration module in the quick power-on and power-off of firing key or ultra-low pressure power down, can be led by control
The time delay of contacts of contactor disconnects reducing main contactor because of arcing or adhesion between the contact that band load being cut off and being caused.

Specific embodiment
The utility model is described in detail below in conjunction with accompanying drawing：
In Fig. 1, the utility model preliminary filling controls integrated module-external circuit to constitute to be included：Main contactor 3, preliminary filling contactor
4, main contactor front voltage Acquisition Circuit 10, main contactor rear end voltage collection circuit 11.
The utility model preliminary filling controls integration module working method：
（One）Preliminary filling control integration module 1 in micro control unit 2 receive firing key output ON grades of signal 12 after,
By main contactor front voltage Acquisition Circuit 10 and main contactor rear end voltage collection circuit 11 to battery and electric machine controller
Two ends carry out voltage acquisition, then by high_voltage isolation circuit 1 and high_voltage isolation circuit 29 enter micro-control unit 2；Simultaneously
Battery and the voltage at electric machine controller two ends and the battery received from CAN 5 that micro-control unit 2 collects itself
Voltage with electric machine controller two ends is contrasted, and the forward and backward two ends of main contactor are calculated respectively（That is battery and electric machine controller two
End）Voltage difference whether meet electric standard.
（Two）If voltage difference meets electric standard, micro-control unit 2 first passes through preliminary filling contactor drive circuit 7 and controls
The adhesive of preliminary filling contactor 4, because preliminary filling contactor and preliminary filling resistance are to be connected in parallel on main contactor two ends together, therefore treats microcontroller
The magnitude of voltage that unit 2 detects main contactor rear end is increased to when meeting main contactor power up requirement, then is driven by main contactor
The dynamic control of circuit 6 adhesive of main contactor 3, while control preliminary filling contactor 4 to disconnect by preliminary filling contactor drive circuit 7, now
Electricity is completed in the high pressure of electric machine controller end.If voltage difference does not meet electric standard, display is fed back to by CAN 5
Part（Instrument）On, i.e., electricity failure in high pressure.
（Three）In electric machine controller normal work, if preliminary filling control integration module 1 in micro-control unit 2 receive from
Power taking switchs the disable signal 13 of output, then micro-control unit 2 controls main contactor 3 to disconnect by main contactor drive circuit 6；
When micro-control unit 2 no longer receives disable signal 13, then micro-control unit 2 is resurveyed and detected two before and after main contactor
The voltage at end, again according to step（One）Carry out electricity in main contactor high pressure.
（Four）In electric machine controller normal work, if the micro-control unit 2 in preliminary filling control integration module 1 is at certain a flash
Between do not receive from firing key output ON grade signal 12, then micro-control unit 2 by main contactor drive circuit 6 control lead
Contact time delay on contactor 3 disconnects, and reaches protection main contactor, prevents the purpose of arcing and adhesion between contact.
