1. If the electric vehicle lithium-ion battery pack is not working properly, it is caused by the damage of lithium ion battery protection board. This problem makes a simple solution to replace the lithium-ion battery protection board to restore the dynamic performance of the lithium-ion battery; 2, If the battery is reduced due to vulcanization, it is necessary to use a lithium ion battery repair instrument to eliminate vulcanization solution; Ion battery or single skewer lithium-ion battery discharge function decreases, and the voltage does not result in a failure of electric vehicle lithium-ion battery function, performance weakening, etc.

, the universal user or maintenance service point is to resolve the battery, this relative cost is higher, if Using the World Energy and Lithium Ion Bad Package Voltage Balance Repair Device, the lithium-ion battery voltage balancing repair instrument is a integrated instrument such as a combined group battery discharge, single string discharge, automatic pressure difference repair, etc. It can quickly repair lithium-ion batteries, restore lithium ion batteries to the best state. Electric vehicle battery repair method is important for all kinds of battery repair instruments and chemical repair liquid.

At present, the best battery repair method is to add small copper-carmatic nano-carbon repair liquid to repair the pulse battery repair instrument. In the battery capacity of more than 50%, the battery is added to the cell, which can restore the battery, such as new, extended life, one year, three 12V or 10 6V series, can be used for professional maintenance people You check, do not at the same capacity, if you can find 1 or two capacity, replacement of sulfate repair method: repair the vulcanized battery to repair the Kuyan repair instrument, adopt a fuzzy digital control theory, by measurement Battery state, in charge, discharge while continuously issuing positive and negative frequency conversion microparticles, with 10 to 20 hours, remove hard sulfate-converted repair method of crystallization in the battery: After the battery is discharged from 10.5 V, Use the bulb deep to discharge 1-5 hours.

Then use the activator, activation repair short-circuit repair method: water battery, can make a clearer, make the short circuit's lead powder! Electric vehicle battery, can quickly short-circuit the positive and negative poles, the short circuit is burn open road repair method: 100A The test battery voltage is 0V is open, with a single measurement method, the place where the opening is measured, the welding is the cover plate above the battery. Some battery covers are ABS adhesive, some batteries are connected to. Some is a skateboard.

Don't damage the cover when you pay attention to the open cover. At this time, you can see the rubber cap of 6 exhaust valves. Open the rubber cap, expose the exhaust hole, can see the inside of the battery through the exhaust hole.

Some battery exhaust valve bases can be rotated, and can be rotated open the exhaust valve base without opening the rubber exhaust valve.
