The invention discloses a vehicle energy management method and device, a storage medium and a vehicle. The method comprises the steps that state information of a storage battery and load information of a vehicle are obtained, the state information comprises at least one of the temperature of the storage battery and the voltage of the storage battery, and the load information comprises low-voltage load power consumption of the vehicle; a target strategy set is generated based on the state information and the load information, and the target strategy set is used for controlling at least one output current value in a DCDC converter and a storage battery of the vehicle to meet low-voltage load power consumption and used for controlling the DCDC converter to perform a charging task or a power-off task on the storage battery. The technical problem of large vehicle energy loss caused by an unreasonable low-voltage energy management method is solved.

    本发明公开了一种车辆能量管理的方法、装置、存储介质及车辆。其中,该方法包括:获取蓄电池的状态信息和车辆的负载信息,其中,状态信息包括如下至少之一:蓄电池的温度、蓄电池的电压,负载信息包括车辆的低压负载功耗;基于状态信息和负载信息生成目标策略集,目标策略集用于控制车辆的DCDC转换器和蓄电池中的至少一个输出电流值,以满足低压负载功耗,以及用于控制DCDC转换器对蓄电池执行充电任务或断电任务。本发明解决了由于低压能源管理方法不合理导致的车辆能量损失大的技术问题。
