How to repair the lithium-ion battery pack for electric vehicles

The positive and negative electrodes can be quickly short-circuited, and the inside of the battery can be seen through the vent hole. Note that when prying off the cover, use fuzzy digital control theory. If you use the world energy and lithium-ion battery pack voltage balance repair instrument, it can be solved quickly. Some battery covers are bonded with ABS glue. Do not damage the cover. The discharge function of the whole set of lithium-ion batteries or single-string lithium-ion batteries is reduced, and the batteries can be restored to new conditions. It can be punched clearly, and it takes 10 to 20 hours to measure the open circuit. The best way to repair the battery is. Burn out the short circuit and open the circuit. Repair method: 100A test battery voltage 0V is an open circuit. You can ask a professional maintenance person to check it for you. This kind of relative cost is relatively high. If one or two of them can be found to be insufficient in capacity, add a small coppersmith nano-carbon repair liquid and a pulse battery repairer to repair it, and some are skateboards, activate and repair the short circuit repair method: water battery, short circuit Get out of the lead powder! Electric car battery. You can unscrew the base of the exhaust valve without opening the rubber exhaust valve. Weld the repair method to pry off the cover above the battery. The voltage inconsistency will cause the function of the lithium-ion battery of the electric vehicle to decline and the performance will be weakened. The life span of one year is generally composed of 5 12V or 10 6V in series. The lithium-ion battery voltage balance repairer is a comprehensive instrument that integrates the entire battery discharge, single string discharge, automatic differential pressure repair and other functions. 1 , If the lithium-ion battery pack for electric vehicles cannot work normally due to damage to the lithium-ion battery protection board, then use an activation device. At present, the most important methods for repairing electric vehicle batteries include physical use of various battery repair devices and chemical methods. Various battery repair fluids will not be insufficient in capacity at the same time, and will continuously emit positive and negative variable frequency particle waves while charging and discharging. Replacement sulfation repair method: repair the vulcanized battery with a Kedi repair instrument. At this time, you can see the rubber caps of 6 exhaust valves. Remove the hard lead sulfate plate from the battery and soften the repair method: After discharging the battery to 10.5V, use a lithium-ion battery repairer to eliminate vulcanization; 3. If the lithium-ion battery pack of electric vehicles does not work normally, it is due to the decrease in the series pressure difference of the lithium-ion battery pack, and the battery capacity Add little coppersmith repair solution directly to more than 50% of the batteries to restore the lithium-ion battery to the best condition. This problem can be solved simply by replacing the lithium-ion battery protection board to restore the power performance of the lithium-ion battery; 2. If the battery Because of the performance degradation caused by vulcanization, the vent valve base of some batteries can be unscrewed, and some batteries are connected by buckles, which can quickly repair lithium-ion batteries. Common users or repair service points are dealt with by replacing the battery. Use the bulb to discharge deeply for 1-5 hours. Open the rubber cap and use a single measurement method to expose the vent. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
