The embodiment of the invention discloses an electric vehicle power control method, an electric vehicle and a computer readable storage medium. The method comprises the steps that a battery managementsystem determines the maximum allowable discharge power and the maximum allowable charge power of a corresponding battery pack and sends the maximum allowable discharge power and the maximum allowable charge power to a vehicle control unit; the vehicle control unit determines a power limiting strategy of the battery pack according to the maximum allowable discharge power and the maximum allowablecharge power of the battery pack in combination with the current state information of the electric vehicle, and sends a power limiting instruction to the motor controller according to the power limiting strategy; and the motor controller controls the motor to execute a power limiting strategy according to the power limiting instruction. According to the scheme, the vehicle control unit determinesthe power limiting strategy of the battery pack based on the maximum allowable charging and discharging power of the battery pack determined by the battery management system and the current state information of the electric vehicle, charging and discharging power control is achieved, and an existing power limiting control scheme is optimized. The riding mileage is effectively increased under thecondition of ensuring normal use of a user.

    本发明实施例公开了一种电动车功率控制方法、电动车及计算机可读存储介质。该方法包括:电池管理系统确定所对应电池包的最大允许放电功率和最大允许充电功率,并发送给整车控制器;整车控制器根据电池包的最大允许放电功率和最大允许充电功率,结合电动车当前的状态信息,确定电池包的限功率策略,并根据限功率策略发送限功率指令至电机控制器;电机控制器根据限功率指令控制电机以执行限功率策略。上述方案由整车控制器基于电池管理系统确定的电池包的最大允许充放电功率以及电动车当前的状态信息,确定电池包的限功率策略,实现充放电功率管控,优化了现有的限功率控制方案,在保证用户正常使用的情况下有效增加了骑行里程。
