The embodiment of the invention discloses an electric vehicle power battery heating method and an electric vehicle, and the electric vehicle power battery heating method comprises the steps that a control module generates a heating instruction in a battery heating mode and outputs a driving control signal according to the heating instruction, the heating instruction comprises at least one of a voltage heating instruction and a current heating instruction; a motor driving module drives the motor according to the driving control signal and heats the power battery in a charging and discharging mode. According to the electric vehicle power battery heating method and the electric vehicle provided by the embodiment of the invention, the vehicle motor can be driven based on the existing power system of the whole vehicle so that uniform heating of the power battery is realized. According to the embodiment of the invention, on the premise that the manufacturing cost of the automobile is not increased, the low-temperature charging time of the whole automobile is remarkably shortened, and the charging speed of the power battery is increased.

    本发明实施例公开了一种电动汽车动力电池加热方法和电动汽车,其中,电动汽车动力电池加热方法包括:控制模块在电池加热模式下产生加热指令,并根据加热指令输出驱动控制信号,其中,加热指令包括电压加热指令和电流加热指令中的至少一种;电机驱动模块根据驱动控制信号驱动电机,并对动力电池进行充放电形式的加热。本发明实施例提供的电动汽车动力电池加热方法和电动汽车,能够基于整车现有的动力系统驱动汽车电机,进而实现对动力电池的均匀加热。本申请实施例在不增加汽车制造成本的前提下,显著减少了整车的低温充电时间,提升了动力电池的充电速度。
