The disclosure relates to a battery electric quantity detection method and device and a vehicle. According to the technical scheme, the method comprises the steps: determining a first charge variationof a battery within preset time according to a current remaining electric quantity of the battery; determining a second charge variation of the battery within preset time according to current information of a battery load end; then acquiring a maximum charge variation of the battery in preset time in the historical discharge process; and finally, determining the current actual residual electric quantity of the battery according to the first charge variable quantity, the second charge variable quantity and the maximum charge variable quantity. According to the technical scheme, technical problems that the residual electric quantity of the battery cannot be verified and the residual electric quantity of the battery is easy to obtain abnormally can be solved.

    本公开涉及一种电池电量检测方法、装置及车辆,该技术方案首先根据该电池当前的剩余电量确定该电池预设时间内的第一电荷变化量;其次根据该电池负载端的电流信息确定该电池预设时间内的第二电荷变化量;然后获取该电池历史放电过程中预设时间内最大的电荷变化量;最后根据该第一电荷变化量、该第二电荷变化量和该最大的电荷变化量确定该电池当前的实际剩余电量。本公开的技术方案能够解决电池的剩余电量无法进行校验,容易出现电池剩余电量获取异常的技术问题。
