The invention relates to the technical field of fuel electric vehicles, in particular to a power battery heating method and device, a vehicle and a storage medium, and the method comprises the steps that the current temperature of a power battery is recognized; obtaining a heating closing threshold value of the power battery and the lowest temperature when the fuel battery is allowed to charge the power battery at rated power, and determining a target temperature for heating the power battery based on the heating closing threshold value and the lowest temperature; and heating the power battery until the current temperature reaches the target temperature. Therefore, the problems that the heating mode of the power battery is simple, the charging and discharging performance of the power battery under the low-temperature condition cannot be brought into full play, the power performance of the fuel cell vehicle under the low-temperature condition is poor, and the user experience feeling is poor are solved.

    本申请涉及燃料电动汽车技术领域,特别涉及一种动力电池的加热方法、装置、车辆及存储介质,其中,方法包括:识别动力电池的当前温度;获取动力电池的加热关闭阈值和燃料电池允许以额定功率对动力电池进行充电时的最低温度,基于加热关闭阈值和最低温度确定动力电池加热的目标温度;对动力电池进行加热,直到当前温度达到目标温度。由此,解决了动力电池的加热方式较为简单,无法充分发挥动力电池低温情况下的充放电性能,导致燃料电池汽车低温情况下的动力性能较差,用户体验感较差等问题。
