Abstract: A power control device is adapted for controlling output power of an electric vehicle including a motor, an accelerator pedal, and a sensing module that senses an accelerator pedal depth and a vehicle speed to provide a sensed pedal depth and a sensed vehicle speed. The power control device includes a condition judging module operable to make a judgment of at least one of an acceleration condition, a starting condition, and a load condition based on the sensed pedal depth and the sensed vehicle speed from the sensing module, and a control module operable to generate a torque output signal according to the judgment made by the condition judging module, so as to control an output torque of the motor.
