您好,我的均衡通道设计如下图所示:

我在单独只开启一个均衡通道时,用示波器测量均衡电阻两端电压,比如6通道,示波器正端接F3右侧,示波器接地夹子接Q4的3脚,均衡波形正常,但是当我同时开启4个均衡通道,比如2、4、6、8时,6和8通道波形出现异常,具体波形如下图,请帮忙分析一下可能的原因,谢谢!

您好,您的问题已经回复,请参考下面的内容:
It looks like the balance current is set to around 130mA when the cell voltage is around 4.2V, so I do not see why the fuses are burning. I do see a couple of things in the schematic that are of concern:
When you enable the balancing, be careful not to enable balancing on adjacent cells. See the note on adjacent cell from the app report:
