How do you repair the battery of electric vehicle?

General lithium electricity normal service life is 3 to 5 years. 3 years battery have maintenance value.

Open the battery box, take out lithium battery monomer and found a bunch of monomer voltage was obviously lower than the others, to monomer lag behind.Bought on the net with the specifications of the monomer, after replacement, recover.Wrapping up glass glue sealing, as well as the original.

With electric vehicle battery charger repair battery:

Electric car charger (voltage, current and electric vehicle battery type, specification is match.Therefore, car charger is not repair the battery pack, to use a bigger size electric power charger.Example: 1, the electric car is 48 v20ah battery specifications, 60 v20ah battery charger can be used to repair;2, 48 v12ah battery pack, 48 v20ah battery charger can be used to repair.

Principle of repair: battery is the main reason for decline in performance sulfide, battery manufacturers after-sales maintenance, in the market for all kinds of battery repair, repair kits are made of high power charging equipment, using the large current, high voltage sulfide, repair the battery.So a bigger size ordinary charger to recharge the battery power has the function of sulfur in addition to repair.

Other methods:

Repair the battery with dry cleaners hot gas water

Not far from the broad masses of users are aware of electric bike journey to run, you need to add distilled water to maintenance repair battery.But is sold on the market of pure water and all kinds of supplements, repair, the action of the battery has a short and then accelerate the battery performance decline, scrap in advance.Because, these metal ions and impurities in the liquid will be corroded battery plate, cause the battery self-discharge and active substances from falling out, causing permanent battery scrap.

Electric lithium batteries are usually at least 10 or more set of lithium batteries in series, and enclosed battery protection board, is completely different from lead acid battery (less quantity, generally no protective plate), in the event of failure, non-professional technicians generally cannot be solved.

Electric cars lithium battery pack damage of generally includes several cases like this:

1, battery protection board is damaged, the electronic density, generally difficult to maintenance;

2, battery protection board in good condition, single individual battery performance becomes poor, find it is not easy;

3, battery protection board in good condition, individual battery short circuit, to screen;

All in all, after electric lithium battery failure, maintenance difficulties, usually find after-sales, technical personnel to solve by manufacturer, or replace the same model electric lithium battery pack.

Is the electric car research institute.To tell you, can't

You need to do is to buy new.Don't go to old change new

Remember: buy batteries must be somebody else's new car battery.You stare at him in. In person.

If you have a quality batteries, wire do you use the + - links, short circuit, the battery is completely failed, can't be a fake.And then to change new one.

Don't let him in bulk of the new battery, must be new car battery.Bulk is generally factory repair..Although good, after all, no new is good, and there is no new battery you spend money
