The invention provides a battery residual energy acquisition method and device, a vehicle, equipment and a storage medium. The battery residual energy acquisition method comprises the following steps: acquiring a target temperature and a target discharge rate of the battery; determining a target dischargeable total energy percentage and a target residual energy percentage under the target temperature and the target discharge rate; and determining the target residual energy according to the target dischargeable total energy and the target residual energy percentage. According to the method of the invention, the target residual energy is calculated according to the target dischargeable total energy and the target residual energy percentage, the target dischargeable total energy and the target residual energy percentage are actual values under the target temperature and the target discharge rate, and influence factors of the temperature and the discharge rate are considered; therefore, the calculated residual energy of the target is more accurate, and the error is smaller.

    本申请提出一种电池剩余能量的获取方法、装置、车辆、设备及存储介质。其中,电池剩余能量的获取方法包括:获取电池的目标温度和目标放电倍率;确定目标温度和目标放电倍率下的目标可放电总能量和目标剩余能量百分比;根据目标可放电总能量和目标剩余能量百分比确定目标剩余能量。本申请实施例根据目标可放电总能量和目标剩余能量百分比计算目标剩余能量,其中目标可放电总能量和目标剩余能量百分比均为目标温度和目标放电倍率下的实际值,均考虑了温度和放电倍率的影响因素,从而计算得到的目标剩余能量更准确,误差更小。
