The invention provides a parameter correction method and device, a vehicle and a computer readable storage medium, and relates to the technical field of vehicle batteries, and the method comprises the steps: obtaining at least two groups of historical data of a battery pack; wherein each group of historical data comprises a historical accumulative charging amount, a historical accumulative discharging amount and a historical ampere-hour compensation value used for residual electric quantity correction; determining a target charging ampere-hour compensation coefficient and a target discharging ampere-hour compensation coefficient according to the at least two groups of historical data; under the condition that the compensation condition of the residual electric quantity is met, the residual electric quantity of the battery pack is corrected according to the target charging ampere-hour compensation coefficient, the target discharging ampere-hour compensation coefficient and the current accumulated charging quantity and the current accumulated discharging quantity of the battery pack. The method can improve the calculation accuracy of the remaining capacity of the battery pack.

    本申请提供了一种参数修正方法、装置、车辆和计算机可读存储介质,涉及车辆电池技术领域,该方法包括:获取电池包的至少两组历史数据;其中,每组历史数据包括历史累计充电量、历史累计放电量和用于剩余电量修正的历史安时补偿值;根据至少两组历史数据确定目标充电安时补偿系数和目标放电安时补偿系数;在满足剩余电量的补偿条件的情况下,根据目标充电安时补偿系数、目标放电安时补偿系数、电池包的当前累计充电量和当前累计放电量,修正电池包的剩余电量。本申请能够提高电池包的剩余电量计算的准确度。
