Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle power control system and a power controller. Background technique [0002] The main task of the power control of a pure electric vehicle is to issue instructions to the motor (through the motor controller) according to the driver's intention (through the accelerator pedal or the brake pedal) and the state of charge of the power battery. Therefore, the input signal here is the angle of the accelerator pedal or the angle of the brake pedal, and the state of charge (SOC) of the power battery, and the output signal is the request for the speed and torque of the motor. Of course, the above is only a very brief introduction. In fact, there are many signals that need to be monitored, such as: the temperature of the motor and each battery, the voltage of each battery, the temperature of cooling water and the speed of the vehicle, etc. These are all input signals. Wh...
