The invention relates to the technical field of automobile control, and provides a battery charge state adjusting method and device, electronic equipment and a storage medium. The method comprises the steps that if it is detected that the number of running times of a vehicle is updated, the lowest battery cell temperature of the vehicle during current running is determined; determining a temperature set to which the lowest temperature of the battery cell of the current running of the vehicle belongs, the element in the set being the lowest temperature of the battery cell corresponding to each running in preset running times, and the preset running times being adjacent running times; under the condition that it is detected that elements in the temperature set correspond to element values, target SOC offset is determined according to the temperature set and the preset corresponding relation between the battery cell temperature and the SOC offset, and when the battery cell temperature is lower than the preset temperature value, the SOC offset is larger than zero; and adjusting the initial SOC value according to the target SOC offset to obtain a target SOC value. According to the embodiment of the invention, the power performance of the vehicle at low temperature can be improved.

    本申请涉及汽车控制技术领域,提供了一种电池荷电状态的调整方法、装置、电子设备及存储介质。方法包括:若检测到车辆的行驶次数更新,确定车辆在当次行驶时的电芯最低温度;确定车辆当次行驶的电芯最低温度所属的温度集合,该集合中的元素为预设行驶次数中每次行驶所对应的电芯最低温度,预设行驶次数为相邻行驶次数;在检测到温度集合中的元素对应有元素值的情况下,根据温度集合以及预先设置的电芯温度与电池荷电状态SOC偏移量之间的对应关系,确定目标SOC偏移量,在电芯温度低于预设温度值时SOC偏移量大于零;根据目标SOC偏移量,对初始SOC值进行调整,得到目标SOC值。本申请实施例能够提升车辆在低温下的动力性能。
