The invention discloses a vehicle, a battery cell balancing method, a battery cell balancing device and a storage medium, and the battery cell balancing method comprises the following steps: when a battery management system of a target vehicle is in any mode, balancing the battery cell according to the to-be-balanced duration of each battery cell stored in a flash memory of a micro-control unit of the target vehicle; balancing the battery cells in the lithium iron phosphate battery pack; re-determining the to-be-balanced duration of each battery cell in the lithium iron phosphate battery pack under the condition that the detection triggering condition is met; and updating the to-be-balanced duration of each battery cell stored in the flash memory based on the re-determined to-be-balanced duration of each battery cell. By applying the technical scheme provided by the invention, the battery cells needing to be balanced in the lithium iron phosphate battery pack can be accurately determined in time, the battery cells are balanced in time, and the utilization rate of the whole battery cells in the lithium iron phosphate battery pack is improved.

    本申请公开了一种车辆及电芯均衡方法、装置、存储介质,该电芯均衡方法包括以下步骤:在目标车辆的电池管理系统处于任意模式的情况下,基于目标车辆的微控制单元的闪存中存储的每颗电芯的待均衡时长,对磷酸铁锂电池包中的电芯进行均衡操作;在达到检测触发条件的情况下,重新确定磷酸铁锂电池包中每颗电芯的待均衡时长;基于重新确定的每颗电芯的待均衡时长,更新闪存中存储的每颗电芯的待均衡时长。应用本申请所提供的技术方案,可以及时准确地确定出磷酸铁锂电池包中需要均衡的电芯,及时对电芯进行均衡操作,提高磷酸铁锂电池包中整体电芯的利用率。
