The invention provides a hydrogen energy vehicle fuel cell heat preservation system and method, electronic equipment and a storage medium. After a whole vehicle is powered off, a whole vehicle controller sends a dormant state entering instruction and a timing self-awakening instruction to a battery management system; when the battery management system is in the awakening state, the battery pack temperature detected by a battery temperature sensor is obtained, and when the battery pack temperature is lower than a preset temperature, the battery management system compares a battery pack SOC value with a preset SOC value, when the SOC value of the battery pack is greater than or equal to the preset SOC value, the battery management system sends a heating instruction to the PTC heating unit, and when the temperature of the battery pack is greater than or equal to the preset temperature, the battery management system enters a dormant state. The technical scheme provided by the invention hasthe beneficial effects that the residual electric quantity of the battery pack is considered while the battery pack is subjected to heat preservation, and the residual electric quantity of the battery pack is not too low while the temperature of the battery pack is ensured to be within an acceptable range, so that a user can quickly use the vehicle again.
本发明提供一种氢能车辆燃料电池保温系统、方法、电子设备及存储介质,在整车下电后,整车控制器向电池管理系统发送进入休眠状态并定时自唤醒指令;电池管理系统处于唤醒状态时获取电池温度传感器检测的电池包温度,当电池包温度低于预设温度时,电池管理系统比较电池包SOC值和预设SOC值;当电池包SOC值大于或等于预设SOC值时,电池管理系统向PTC加热单元发送加热指令;当电池包温度大于或等于预设温度时,电池管理系统进入休眠状态。本发明提出的技术方案的有益效果是:在对电池包进行保温的同时考虑了电池包的剩余电量,在保证电池包温度在可接受范围的同时,保证电池包剩余电量不至于过低,方便用户快速进行再次用车。
