How to Repair an Electric Vehicle's Lithium Battery

Lithium batteries for electric vehicles generally consist of at least ten lithium batteries connected in series, with built-in battery protection plates. This is completely different from lead acid batteries (which are few and far between). generally do not have protective plates). When a fault occurs, non-professional technicians usually cannot resolve it.

Damage to electric vehicle lithium batteries generally includes the following situations:

1. The battery protection board is damaged, and the electronic components inside are densely packed, which is generally difficult. to repair;

2. The battery protection panel is in good condition. If the performance of a single battery deteriorates, it is not easy to find it;

3. is in good condition. If some batteries are short circuited,go to the inspection service < /p>

In short, after an electric vehicle's lithium battery fails, it is generally difficult to repair; by the after-sales service, and the manufacturer's technicians solve the problem, or replace the lithium battery of the same model of electric vehicle.

Detailed information:

< p>1. Charge it every day. Even if the lithium battery in your electric vehicle can last 2 to 3 days on a single charge, it is still recommended to recharge it daily. Since the used lithium battery is in a shallow cycle state, charging it daily will extend the life of the electric vehicle lithium battery.

2. Charge on time. Since lithium batteries will enter the sulfidation process after being discharged, if charged in time, less serious sulfidatione can be eliminated. Therefore, lithium batteries should be charged as soon as possible after use to keep the battery as full as possible.

3. Regular deep discharge. Regularly deep discharging the battery is also beneficial to “activate” the battery, which can increase battery capacity slightly. The general method is to completely discharge the battery regularly.

If the lithium battery is broken, you can usually go to the store where you purchased the battery, which will provide after-sales service, or you can go to a nearby electric vehicle repair point.

If the lithium battery of an electric vehicle is broken, you can go to the sales site where you purchased the lithium battery to repair it. Especially during the warranty period, repairs on the sales site are possible.bles. usually for free. If the warranty period has expired, you can go to the nearest repair shop and find a professional repairer to repair it. However, it should be noted that different repair shops will have floating suggestions on repair prices. Choose a reputable repair shop for repairs.

Before repairing, you must carefully diagnose the cause. If it is determined that there is a problem with the battery itself, you should choose to replace it rather than repair it. For lithium battery repair, you can choose an officially designated repair shop. It is generally recommended to use formal channels. You can also choose a regular third-party technical service provider, such as graphene repair shop, to guarantee the technical level and parts. quality and guarantee safety, reliability and reliabilityusability.

Lithium battery repair methods:

1. This method is actually better and also relatively simple. Car owners can do this at home. They just seal the lithium battery of the electric car with plastic film or something, then put it in the refrigerator or freezer at home. then take it out and put it in the refrigerator. Leave it at room temperature for another two days, which will have some restorative effect on the lithium battery.

2. Activation method. The activation method is also relatively simple. You can find a charger with relatively low current to charge the lithium battery. After two hours of charging, return to the original charger and continue charging. This will have some activation effect on lithium. Battery of course, it also has corresponding repair effects.

3. Usea high current charger to charge the lithium battery. Find a charger with higher current than the original charger to charge the lithium battery for two hours, then switch to the original charger. and continue charging until it is full. Through this high current charging, the battery can be activated, which helps to increase the battery capacity and has a certain restorative effect on the battery.
