What is the cause of the lithium battery drum in the electric vehicle?

The reason for electric vehicle lithium-ion battery drums: 1, the quality of charger is low, the price war is killed, the charger quality is declining, using inferior plate, refurbishment or low inferior device, fever, parameter drift is not accurate, so that the charging limit is out of control, Internal gas extrusion in the lithium ion battery pack results in a deformation of the battery case and even explosion. 2, the charging time is too long, some users don't have time concept, thinking that inserting a charging full automatic stop, I don't ask, some even fill two days and two nights, I used it for a long time, electric car lithium ion The battery life will be threatened. If over charge can result in a large amount of gas flush poles, the internal active substances caused by the internal active substance, shorten the battery life, so that the battery is lost, affecting the decomposition of the electrolyte, so that the battery temperature increases Drug! 3, the internal fault of the battery has quality problems, micro-short, ignorant, water, water, causing thermal out of control, making the internal pressure of the lithium ion battery becomes large, the safety valve does not release the pressure, the exhaust valve hole clogged , Increase the internal gas pressure to cause the battery case to deform, and swell.

4, forget the charger with charger, just borrow one, or a family of several electric car size chargers, this is very common, each electric car battery brand has its own interface, current value, different electric The car may have different charging voltages, the charging current is different, the natural charging time and charging efficiency are different, and the charger, the battery is large, the charger is small, the charge is low, the battery is small, the charger is large, the charging, the heat is out of control, will be drumming. .
