What kind of battery does electric vehicle battery break during shelf life?

The commitment of General electric vehicle manufacturers and battery manufacturers is to use battery packs for one year, and individual commitment packs for one and a half years or two years. However, this bag means that when you change the battery, you only change the battery that can be used instead of replacing the new battery. Generally, the repaired battery can not be used for a long time. Of course, there are also some manufacturers that have better services. Quality problems can be replaced within 8 months. If the appearance of the battery is damaged due to human causes, including battery bulging that has been tested for non-battery quality problems, it can only be downgraded to swing batteries.

National Insurance doesn't mean you can go to a store and change batteries for free. You can only change it at the manufacturer's designated store. When changing batteries, the store will replace a group of batteries together. Of course, you can also ask the store to change only one section, but the other batteries must be good, and the replaced batteries must be similar to the batteries that have not been replaced. Performance, This will ensure that you can use the battery for a longer period of time.

2, electric vehicle batteries during the shelf life of the quality problems, the manufacturers of the battery has a shelf life; Quality problems occurred within 8 months of the factory for new batteries, 8 to 12 months after the factory quality of maintenance battery replacement warranty 7 months, 12 to 15 months after the factory quality problems to replace the maintenance battery warranty 3 months, some manufacturers are 8 to 15 months to replace the maintenance battery Seven months warranty.

3, the charger parameter does not match causes the heat to lose control when charging, causing the battery to swell, this is the human cause. The quality problem of the inner battery group itself, such as the microshort circuit of the polar group and the lack of acid, will also cause the battery heat to swell out of control. This is the quality problem of the battery itself.

4, to detect whether the charger parameter is a problem, the battery can be discharged using a matching charger to charge the drum battery, observe and monitor the surface temperature of the battery, if the temperature is not unusually high to hot(slightly hot is normal), It can be concluded that it is not an internal problem of the battery polar group, but it is caused by the mismatching of charger parameters. It is a human cause, and vice versa.

Electric vehicle batteries have been replaced once during the warranty period, and the replacement battery warranty period is still one year. It doesn't take long to break, and it can be changed again. This is rare.
