The invention provides a method, a device and a system for displaying the remaining capacity of a battery and a vehicle, and the method comprises the steps: building the relation between the real SOC and the display SOC of the battery, dividing the display SOC intervals and the total discharge capacity of the battery, calculating the theoretical discharge capacity of each display SOC interval, and adjusting the real SOC interval to enable the real SOC interval to correspond to the display SOC interval, so as to display the remaining capacity of the battery. And the discharge capacity of the real SOC in each interval is ensured to meet the error range of the theoretical discharge capacity of the SOC interval, so that uniform discharge in the whole real-time discharge process is realized, the driving mileage is conveniently calculated, the whole vehicle control is optimized, and the driving comfort is improved.

    本发明提供一种电池剩余电量显示方法、装置、系统及车辆,所示方法是通过建立电池真实SOC与显示SOC之间的关系,通过划分显示SOC区间以及电池的总放电量,计算每个显示SOC区间的理论放电量,通过调节真实SOC的区间,使其与显示SOC区间相对应,保证真实SOC在每个区间的放电量满足显示SOC区间的理论放电量的误差范围,由此实现实时放电全过程的均匀放电,便于续驶里程的计算,优化整车控制,提高驾驶的舒适性。
