The embodiment of the invention provides a charging equalization circuit of a series power pack, a charging equalization method and a vehicle, and the charging equalization circuit comprises at least two power packs which are connected in series and a control unit. Each power pack comprises a power supply and an adjusting circuit, the adjusting circuit and the power supply are arranged in parallel, the adjusting circuit is connected with the control unit, and a first common end between two adjacent adjusting circuits is connected with a second common end between two adjacent power supplies; when it is detected that the difference value between the electric quantity of any power supply during charging and the electric quantity in the full charge state is smaller than a preset electric quantity threshold value, the control unit is used for controlling the adjusting circuit to adjust the equalizing charging process between the series power supply sets. According to the embodiment of the invention, overcharge of the power supply can be avoided, and a current path for charging other power supply groups is provided.

    本申请实施例提供一种串联电源组的充电均衡电路、充电均衡方法和车辆,所述充电均衡电路包括,至少两个相互串联的电源组和控制单元;每个所述电源组包括,电源和调节电路,所述调节电路与所述电源并联设置,且所述调节电路与所述控制单元连接,相邻两个所述调节电路之间的第一公共端与相邻两个电源之间的第二公共端连接;当检测到充电时任意一电源的电量与充满状态电量之间的差值小于预设电量阈值时,所述控制单元用于控制所述调节电路调节串联电源组之间的均衡充电过程。本申请实施例可以避免动力电源过充,同时提供其他动力电源组充电的电流路径。
