The invention relates to a battery heating method, device and equipment, a medium, a product and a vehicle, and relates to the technical field of battery heating. The technical problems that in the prior art, when a battery is heated, the risk of overcurrent exists, and unexpected torque pulsation occurs in a motor are at least solved. Comprising the steps that request current and request frequency are obtained, the request current is pulse current when a battery is heated, and the request frequency is used for determining the total duration of a battery heating period; based on the request current and the request frequency, an energy charging duty ratio is determined, the energy charging duty ratio is the ratio of a first duration in the battery heating period, and the first duration is the duration of charging the motor by the battery; based on the request frequency and the charging duty ratio, first duration and second duration are determined, and the second duration is the duration of discharging the battery by the motor in the battery heating period; and in the battery heating period, the duration of charging the motor by the battery is controlled to be a first duration, and the duration of discharging the battery by the motor is controlled to be a second duration.
本申请涉及一种电池加热方法、装置、设备、介质、产品及车辆,涉及电池加热技术领域。至少解决相关技术中对电池进行加热时,存在电流过流的风险,且电机出现非预期转矩脉动的技术问题。包括:获取请求电流和请求频率,请求电流为对电池进行加热时的脉冲电流,请求频率用于确定电池加热周期的总时长;基于请求电流和请求频率,确定充能占空比,充能占空比为电池加热周期内第一时长的占比,第一时长为电池对电机进行充能的时长;基于请求频率和充能占空比,确定第一时长和第二时长,第二时长为电池加热周期内电机对电池进行放电的时长;在电池加热周期内,控制电池对电机进行充能的时长为第一时长,并控制电机对电池进行放电的时长为第二时长。
