Integrated control device for pure electric vehicle

The invention discloses an integrated control device for a pure electric vehicle. The integrated control device integrates main control plates of a vehicle control unit and a battery management system on the same circuit board, and has the functions of the vehicle control unit and the battery management system, wherein a microprocessor VBU is the core of the integrated control device, and comprises two independent microcontrollers; two independent power supply chips respectively supply power for the two microcontrollers independently. The two microcontrollers are in communication through an SPI, can mutually detect whether abnormal exist or not, and process the abnormal circumstance in real time, so that the overall system can be kept in a normal operation condition. The integrated control device has the advantages that more space is saved for arrangement of parts of the pure electric vehicle, and more benefits are brought for cost conservation for the whole vehicle; the functions and the safety level necessary for the original vehicle control unit and battery management system are reserved; more input signals can be collected, more output signals can be controlled, and deep level integration of the two functional controllers is realized to the maximum extent.
