The invention relates to a vehicle battery heating method, a motor controller, a vehicle and a storage medium, and the method comprises the steps: receiving the current locked-rotor current of a battery when the vehicle is in a reserved heating mode; the optimal locked-rotor current of the whole vehicle is matched according to the current locked-rotor current; and the motor output torque of the vehicle is controlled according to the optimal whole vehicle locked-rotor current, auxiliary heating is generated, and the auxiliary heating is used for conducting supplementary heating on a battery while PTC heating is conducted. According to the motor controller, the optimal whole vehicle locked-rotor current is matched according to the battery locked-rotor current and transmitted to the motor to drive the motor to emit heat, so that PTC heating is supplemented, the starting time of the vehicle in a low-temperature environment is shortened, the competitiveness of the motor in the market is improved, and the driving experience of a user is improved.

    本申请涉及一种车辆电池加热方法、电机控制器、车辆及存储介质,其中,方法包括:接收车辆处于预约加热模式下的电池的当前堵转电流;根据当前堵转电流匹配最佳整车堵转电流;按照最佳整车堵转电流控制车辆的电机输出扭矩,产生辅助发热量,以在PTC加热的同时,利用辅助发热量对电池进行补充加热。本申请基于电机控制器根据电池堵转电流,匹配最佳的整车堵转电流并输送至电机,以驱动电机发热,从而对PTC加热进行补充,缩短了车辆在低温环境下的启动时间,提高了电机在市场上的竞争力,改善了用户的驾乘体验。
