The invention discloses a motor controller and a motor control method of an electric vehicle, the motor control method of the electric vehicle is applied to the motor controller, the motor controller is used for controlling a motor, and the motor controller is powered by a battery. The motor control method comprises the following steps: when a main relay of the motor controller suddenly trips, in a first stage, a diode and a first current-limiting resistor of a first group of protection circuits of the motor controller reinject surge current to the battery so as to suppress the surge current; and in the second stage, the control unit of the motor controller conducts a discharge switch of a second group of protection circuits of the motor controller, and the discharge switch and a second current-limiting resistor of the second group of protection circuits release the surge current to a reference voltage range.
本发明公开一种电动车辆的马达控制器及马达控制方法,电动车辆的马达控制方法应用于马达控制器,该马达控制器用以控制马达,该马达控制器由电池所供电。该马达控制方法包括:当该马达控制器的主继电器突然跳脱时,于第一阶段内,该马达控制器的第一组保护电路的二极管及第一限流电阻将突波电流回注至该电池,以抑制该突波电流;以及,于第二阶段内,该马达控制器的控制单元导通该马达控制器的第二组保护电路的放电开关,该第二组保护电路的该放电开关及第二限流电阻将该突波电流释放至参考电压范围。
