1. The first is that the processing manufacturing process is unqualified. If the electric car market is mixed, many companies are limited due to the limited manufacturing level of the lithium-ion battery, and there is no average of the electrode coating, and there is no stitches to the battery.
Such a battery is extremely easy to drum. 2. Lithium ion battery pack overflow.
The battery overshoot is easy to cause fire, and on the other hand, it will also cause battery drums. The battery overshoot will cause a lot of heat, causing electrolyte analysis and gasification, and the battery is drumping. 3.
The charging current is too large. At present, many owners have privately modified batteries and electric vehicles. In addition, the owner is cheap to purchase cheap mismatched chargers, and there are specified voltage currents in different sizes.
If the charging current is too large, result The precipitation of the electrode plate is too fast, which in turn leads to insufficient chemical reactions, too high, and if the exhaust is not timely, the battery drum will appear. 4, the safety valve pressure is too high, industry insiders know that electric car batteries have a safety valve in order to ensure safety, when the pressure in the electric vehicle battery rises, the safety valve will automatically open, perform pressure to ensure Battery internal and external air pressure balance. If the pressure in the lithium-ion battery is rising, the safety valve cannot be opened normally.
Over time, because the pressure is too high in the battery, the internal and external gas pressure is unbalanced, the phenomenon of drums will occur. 5, mixed charger, some electric vehicles in the owner of the car do not stop one, when charging electric car, often mixed. For example, with a 60 volt charger charge 48 volt battery, or a low battery charger, which will be charged for a long time, it will cause a bulk bag.
6. The charging time is too long. Under normal circumstances, the battery is overflowing for 12 hours, but some friends often don't care if they are inserted with the charger, and they have been charged for one.
Even more than 24 Hours of hours. Excessive charging mode will definitely cause very bad damage to the battery, and the lithium-ion battery drum is definitely inevitable. 7.
Use the fast charge method, although the electric car has brought us great travel convenience, but there is still no electricity on the road, so sometimes it can only use the fast charge. However, this way is easy to cause lithium-ion battery pack drum bags.
