我们在做测试40z50 r1的方案在放电欠压保护后，用3A充不了电，调成1A可以充电，充了一会 调成3A 可以充电，请问这种情况是什么原因引起的？谢谢
您好,请参考下面内容
I checked the settings to see if the Pre-charge (PCHG) feature was enabled, but it looks like PCHG is disabled, so this is not about pre-charging with the gauge.
The closest settings that look to what you are describing is the low temperature charging current. Maybe the settings are telling the charger to charge with a current of 1A.
If this is not the issue, then the charger might have a built-in pre-charge phase.
这个是不能用3A充电的registe截图
