The invention discloses a battery heating system, a battery heating method, equipment and a storage medium, and belongs to the technical field of vehicles. A control device in the system obtains a target temperature required to be reached by a battery when a vehicle is started; based on the target temperature, a first wake-up signal is sent to a vehicle control unit; after the vehicle control unit is awakened, a second awakening signal is sent to the battery management system; after the battery management system is awakened, a first closing signal is sent to the cathode relay, and a second closing signal is sent to the heating relay; wherein the first closing signal and the second closing signal are respectively used for controlling the cathode relay and the heating relay to enter a closed state; the cathode relay and the heating relay entering the closed state and the thermistor form a current path; and after the thermistor is electrified, the battery is heated to a target temperature. According to the system, when the vehicle is started, the battery can reach a proper discharge temperature, so that the discharge temperature of the battery in a low-temperature environment is increased.

    本申请公开了一种电池加热系统、电池加热方法、设备及存储介质,属于车辆技术领域。该系统中控制设备获取车辆启动时,电池所需达到的目标温度;基于目标温度,向整车控制器发送第一唤醒信号;整车控制器在唤醒后,向电池管理系统发送第二唤醒信号;电池管理系统在唤醒后,向负极继电器发送第一闭合信号,向加热继电器发送第二闭合信号;其中,第一闭合信号和第二闭合信号分别用于控制负极继电器和加热继电器进入闭合状态;进入闭合状态的负极继电器和加热继电器与热敏电阻形成电流通路;热敏电阻在通电后,将电池的温度加热至目标温度。该系统可以在车辆启动时,使电池达到合适的放电温度,从而提升电池在低温环境中的放电温度。
