Electric vehicle lithium battery repair methods and repair technology analysis

Repair method for lithium battery of electric vehicle 1. If the lithium battery pack of electric vehicle cannot work normally due to damage to the lithium battery protection board, this problem can be solved simply by replacing the lithium battery protection board to restore the power performance of the lithium battery; 2. If the performance of the battery is reduced due to vulcanization, use a lithium battery repairer to eliminate vulcanization; 3. If the lithium battery pack for electric vehicles does not work properly because the series pressure difference of the lithium battery pack decreases, the entire set of lithium batteries Or the discharge function of a single string lithium battery is reduced, and the voltage inconsistency causes the function of the lithium battery of electric vehicles to decline, and the performance is weakened. Common users or maintenance service points are solved by replacing the battery. This relative cost is relatively high. Lithium battery pack voltage balance repair instrument can be processed quickly. Lithium battery voltage balance repair instrument is a comprehensive instrument that integrates the functions of whole battery discharge, single string discharge, and automatic differential pressure repair. It can quickly repair lithium Battery, restore the lithium battery to its best condition. Electric vehicle lithium battery repair technology From the structure of the electric vehicle lithium battery, the electric vehicle lithium battery is mainly composed of lithium batteries, protection boards and related accessories. The common lithium battery failures are that the battery has no output, the battery cannot be charged, and the battery Dissatisfied charging and low battery life problems. However, these problems are mainly caused by the damage of the lithium battery protection board itself and the damage of the lithium battery cell. Technically speaking, these common faults can be completely repaired. 1. Many electric vehicle lithium batteries seem to be unusable, but in fact, you don’t really know it. First, you must use a lithium battery balance repairer to test the battery voltage, discharge and pressure difference to identify which part or which The battery is damaged, causing the entire battery pack to malfunction. 2. After testing the root cause of the failure problem, the balance repairer is used to solve the problem technically. Generally, the problem with lithium batteries is mostly because the lithium battery protection board is damaged or the lithium battery cell is damaged. If the protection board is damaged , You only need to replace the protection board. If the battery cell function is damaged, use the world energy and lithium battery balance repair instrument to repair the lithium battery pressure difference, so that each string of the battery pack can be charged and saturated, and at the same time Discharge can also maximize the use of stored electricity. 3. The general balanced charge on the market is to directly charge the pressure difference of each battery pack to 4.2v, which is a high-voltage repair. This repair principle will still exist after a discharge cycle, and the battery pack pressure difference will still exist. After the power is discharged, the repair must be performed again. The voltage balancer uses the entire set of discharges and single string discharges to make the voltage of each string reach the lowest value protected by the protection board, and then uses the highest string of the entire battery as a reference value to perform low-voltage balance repair, which is a low-voltage repair , So repairing once can be used for a long time, curing the symptoms and the root cause.
