ON grades of power supplys 6 (12V) of vehicle, power cut-over relay 4 movable contact access vehicle battery power supply 7 (12V), power supply conversion after
The both ends of the coil of electric appliance 4 connect the positive-negative power interface of Vehicular charger 3 respectively, vehicle traction selection relay 2
One end connection vehicle master of normally-closed contact bears one end of the coil of contactor 1, and the normally closed of vehicle traction selection relay 2 is touched
The other end ground connection of point, the both ends of the coil of vehicle traction selection relay 2 connect the positive negative electricity of Vehicular charger 3 respectively
Source interface, vehicle master bear the main negative control end of vehicle power supply of the other end connection battery management system 5 of the coil of contactor 1, car
The both ends access vehicle drive power 8 of the normally opened contact of main negative contactor 1.
In above-mentioned technical proposal, the CAN of the CAN bus communication ends connection Vehicular charger 3 of the battery management system 5
(Controller Area Network, controller local area network) bus communication end (including CAN-L and CAN-H).Cell tube
Reason system 5 can be managed the charging process of Vehicular charger 3.
In above-mentioned technical proposal, the positive-negative power interface of the Vehicular charger 3 is positive and negative 12V interfaces.
In above-mentioned technical proposal, the power cut-over relay 4 is single-pole double-throw relay.
In above-mentioned technical proposal, the vehicle drive power 8 is 384V power supplys.
In above-mentioned technical proposal, vehicle master bears the vehicle traction electricity that contactor 1 is used to control vehicle whether to access 384v
Source.The vehicle traction selection relay 2 is normally closed relay.
In above-mentioned technical proposal, when the coil of power cut-over relay 4 is not powered, common is connected with stationary contact, electricity
