6.根据权利要求5所述一种新能源电池PCBA进水检测及除湿系统的工作方法，其特征在于，当湿气达到上限值时，MCU控制模块开启冷凝片，将水气集中转换成水滴，水滴沿着水道，由特定位置的海棉吸收，防止内部水气对电芯极耳的腐蚀。
7.根据权利要求5所述一种新能源电池PCBA进水检测及除湿系统的工作方法，其特征在于湿度未超过上限值时，电池继续使用，但MCU控制模块会通过通讯预警或声光预警方式告之用户，并记录数据。
8.根据权利要求5所述一种新能源电池PCBA进水检测及除湿装置，其特征在于，当湿气超过上限值时，MCU控制模块会通过通讯预警或声光预警方式告之用户，电池启动锁死功能，此时电池将无法充放电，PCBA断电，防止二次损坏。
9.根据权利要求5所述一种新能源电池PCBA进水检测及除湿装置，其特征在于，当MCU控制模块通过水滴深度检测极，检测到电池进水后，记录进水数据，并通讯或声光报警后立马启动电池锁死功能，此时电池将无法充放电，PCBA断电，防止二次损坏。
