How to Repair the Battery of Lithium Battery Electric Vehicle

Open the battery cover and remove six safety hats.

Fill each hole with distilled water with syringe. If 1.28 standard electrolyte is added, the plate may burn out because of the high acid solubility. For example, when we eat hot pot, why do we eat more and more salty? That is to say, when water evaporates, salt will not evaporate through steam. In the same way, the acid in the battery will not evaporate. What is missing is water. So we only need to add about 20-30 ml distilled water in each small hole.

The battery still half an hour, after full plate around the sponge absorb moisture. Then with discharge resistance, the battery, after all, there is no resistance, can replace with a 12 v bulbs, such as: motorcycle headlights, car lights can, as long as you can have the effect of discharge to 0 v. How to judge whether a battery is nearly close to no electricity, cement resistance discharge resistor body hot at the beginning, slowly gradually is not hot, when the battery is the power went out. Light bulbs, more directly, as long as see light slowly not lit, means the end of the battery discharge, the discharge time depends on the battery discharge capacity, we can put the battery first ride to maintain when no electricity, so that we can shorten the time of discharge.

After the discharge to recharge the battery, conditional can use pulse charging ways, because of the pulse charging method can effectively remove the plate vulcanizing, improve the capacity of the battery. No car can also charge to replace.

(to the accumulator) as shown below in pulse charging, for example.

Charging is completed, with a syringe, each hole excess water. A total of 6 holes, step by step to complete.

Cover the hat and cap, can use loading.

Electric cars The lithium battery Usually there are at least 10 groups or more Lithium electricity Pool 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 The 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.

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.
