The invention relates to a charging power-on control method based on a battery electric vehicle. The method comprises the following steps that after receiving an externally-connected high-voltage alternating current, a charger sends a charging awakening signal to a vehicle control unit; the vehicle control unit sends remote frame messages to high-voltage components of a vehicle CAN (Controller Area Network) communication network by virtue of a vehicle network and requests each high-voltage component to supply a feedback signal of whether a severe fault exists; if the feedback signal refers to no fault, the electric quantity of a battery pack is determined to be not full; the charger judges whether a main negative relay and a main positive relay are sucked or not; the vehicle control unit controls the main negative relay and the main positive relay to perform charging control. Charging power-on process time sequence planning is performed on an electric vehicle structure state based on the scheme, so that the whole vehicle can perform a normal operation process.
