Three-in-one electric vehicle controller

The invention provides a three-in-one electric vehicle controller. The three-in-one electric vehicle controller comprises a motor controller, a charger and a DC/DC converter; the charger and the DC/DCconverter are both connected with the motor controller and share an MCU of the motor controller; and the three-in-one electric vehicle controller is connected with a battery pack, a motor and a VCU of a whole vehicle. According to the three-in-one electric vehicle controller, as the motor controller, the DC/DC converter and the charger are integrated together and are controlled by the MCU in themotor controller, only one single board and one housing are needed; and therefore, external wiring is simple, the occupied vehicle assembling space is small, the system reliability is high, and the cost is low. 一种三合一电动车控制器，所述三合一电动车控制器包括一个电机控制器、充电器和DC/DC转换器，所述充电器和DC/DC转换器均与电机控制器相连接且共用电机控制器的MCU，所述三合一电动车控制器与整车的电池包、电机及VCU相连接。本装置将电机控制器、DC/DC转换器和充电器集成在一起，通过电机控制器里的一个MCU进行控制，只需一个单板和一个外壳，外部接线简单，占用整车装配空间小、系统可靠性高，成本低。
