我将TPS63020DSJR芯片用在3.7V聚合物电池系统中，负载有4G模块、GNSS模块等，手册中说可以把电池放电到2V以下，即使又电池保护板，会不会导致电池过放而鼓包？我现在遇到的正是这个问题，是锂电池保护板问题还是TPS63020频繁的榨干电量的问题导致的过放鼓包？
I used the TPS63020DSJR chip in a 3.7V polymer battery system, with loads such as 4G modules and GNSS modules. The manual states that the battery can be discharged below 2V. Even with a battery protection board, will it cause the battery to over discharge and bulge? The problem I am currently facing is precisely this. Is it a problem with the lithium battery protection board or is it caused by the frequent depletion of the TPS63020 battery, resulting in excessive bulges?
