The invention discloses a battery pack and a method for performing voltage acquisition and battery energy equalization on the battery pack. The battery pack comprises a plurality of rechargeable batteries connected in series; each rechargeable battery comprises a battery cell, a positive tab and a negative tab, wherein the positive tab and the negative tab are arranged on two opposite end parts of the battery cell. The battery pack is characterized in that the battery cell of at least one rechargeable battery is also provided with an auxiliary tab, wherein the auxiliary tab is configured to have the potential equal to that of one of the positive tab and the negative tab, and at least part of the auxiliary tab is used for being connected with a circuit for voltage acquisition and/or battery energy equalization. The battery pack adopting the above design is beneficial to voltage acquisition and battery energy equalization.

    公开一种电池组、对该电池组进行电压采集、电池能量均衡的方法,该电池组包括多个串联的可充电电池,可充电电池包括:电芯、设在电芯两相对的端部上的正极耳和负极耳;其特征在于,其中至少一个可充电电池的电芯还设有辅助极耳;其中,辅助极耳被配置为其电位与正极耳和负极耳中之一的电位是相等的,且至少部分辅助极耳用于与进行电压采集和/或进行电池能量均衡的线路连接。采用该设计的电池组对方便电压的采集、电池能量均衡是有利的。
