New-energy entire car controller integrated with motor control function and battery main control function

Abstract

The invention provides a new-energy entire car controller integrated with a motor control function and a battery main control function. An original entire car control function, a BMS main control function and an MCU digital signal processing function are completely integrated in the entire car controller, so that a special BMS main control module and a special MCU digital signal processing module are not needed any more; the components are connected together with an internal bus on a controller circuit board by virtue of internal connecting wires so as to form a complete controller hardware circuit. The new-energy entire car controller software integrated with the motor control function and the battery main control function is realized by virtue of an entire car control algorithm, a motor control algorithm and a battery main control algorithm. The controller quantity is reduced, and wire beams of the entire car are simplified, so that the complexity degree of an entire car electronic system is reduced, and the system is relatively simple and reliable; under the condition of less controller quantity, less special diagnosis devices are needed, so that the after cost is lowered; furthermore, vehicle use data collection is convenient and after sale service is convenient.

AI Technical Summary

Problems solved by technology

The simultaneous existence of multiple controllers such as BMS, MCU, and VCU makes the structure of new energy vehicles complex and the cost is high, and the existence of multiple controllers makes it more difficult to arrange and wire the original limited space in the car, and increases the cost of vehicle output. The workload and difficulty of maintenance in case of failure
