The invention relates to a vehicle battery state of charge (SOC) correction control method and device, a storage medium and computer equipment. The method comprises the steps that operation conditionparameters of a vehicle are obtained, and the operation condition parameters at least comprises at least one of a current battery cell voltage, a current battery SOC and a current driving slope; whena battery SOC correction condition is met, an SOC correction strategy corresponding to the vehicle is determined according to the operation condition parameters, and the SOC correction strategy comprises battery charging correction, battery discharging correction and first discharging correction and then charging correction of a battery; and battery SOC correction is carried out on the vehicle according to the SOC correction strategy corresponding to the vehicle until a correction completion condition is satisfied. The battery SOC correction strategy of the vehicle is determined through the operation condition parameters of the vehicle, the charging and discharging of the battery can be controlled in the driving process, the SOC of the battery is corrected, and the SOC calculation precision is improved. In addition, various SOC correction strategies are beneficial to improving the SOC correction precision, reducing the correction time and improving the correction efficiency.

    本申请涉及一种车辆电池SOC校正控制方法、装置、存储介质及计算机设备,获取车辆的运行工况参数,运行工况参数至少包括当前电池单体电压、当前电池SOC以及当前行驶坡度中的至少一种;当满足电池SOC校正条件时,根据运行工况参数确定车辆对应的SOC校正策略,SOC校正策略包括:电池充电校正、电池放电校正以及电池先放电后充电校正;根据车辆对应的SOC校正策略对车辆进行电池SOC校正,直至满足校正完成条件。通过车辆的运行工况参数来确定车辆的电池SOC校正策略,可以在行车过程中实现对电池充电和放电的可控,并对电池的SOC进行校正,提高SOC计算精度。另外,多种SOC校正策略有利于提高SOC校正的精度,减少校正时间,提高校正效率。
