How to repair and activate the lithium iron phosphate battery pack for electric vehicles?

How to repair lithium iron phosphate battery packs for electric vehicles. When users encounter problems with lithium iron phosphate battery packs, they will take them to repair shops and merchants to replace them with new lithium batteries. So, is the lithium iron phosphate battery pack really not repairable? Is it technically difficult to break through? After years of development of lithium batteries, there are already brands that have made achievements in lithium battery pack repair technology. Therefore, the repair of lithium iron phosphate batteries for electric vehicles can be done. 1. Reconfiguration: After the entire set of lithium iron phosphate batteries is damaged, we often perform charge and discharge tests on the lithium battery packs of electric vehicles. During the inspection, it is often found that 50% of the batteries in a set of batteries are not damaged. The reason is that in the series-connected battery pack, individual batteries lag behind, resulting in a decline in the function of the entire battery pack, so that the function of the entire battery pack is reduced. 2. Water replenishment: A replenishment of the battery used for the lithium battery of electric vehicles for about 4 months can prolong the service life of the battery and extend the time evenly to more than 3 months. It should be noted that after each refilling, the battery is in an overcharged state to turn the battery from a quasi-lean liquid to a lean-liquid state, and this overcharge is good for improving the battery capacity. 3. Eliminate vulcanization: use lithium iron phosphate battery repair equipment to eliminate vulcanization of the battery. 4. Particle generator: Take the particle generator in parallel with the battery to repair the lithium battery pack. This method is better for repairing lithium batteries in electric vehicles, but because the repair is relatively thorough, if there is no over-discharge, the possibility of battery vulcanization is often completely eliminated for the continued use of lithium batteries in electric vehicles. 5. Comprehensive repair methods for lithium iron phosphate battery packs for electric vehicles: Periodic inspections are adopted for lithium iron phosphate battery packs for electric vehicles, desulfurization and water replenishment are carried out in time, and single batteries are charged and reconfigured. The battery description, if it is maintenance-free, generally do not add water. If you want to add water, first test the electrolyte density of the electric vehicle battery itself, and select the corresponding concentration or non-concentration water to supplement according to different situations, so that the capacity of the lithium iron phosphate battery can be increased or the service life of the lithium iron phosphate battery can be increased. How to activate the lithium iron phosphate battery pack for electric vehicles The lithium iron phosphate battery of electric vehicles is not activated like the nickel-metal hydride batteries in the past, and the lithium battery can be used normally if it overflows with electricity. In addition, lithium batteries can be recharged at any time, unlike nickel-metal hydride batteries that have to be used up to charge. In fact, there is no special way to activate the lithium iron phosphate battery electric vehicle. The lithium battery will naturally activate when the electric vehicle is driving. Because the lithium battery has no memory effect, it can be charged at any time. So you have to develop a good habit of charging in time after use, which can extend the battery life by 3-5 times. The first activation method is to find a set of lithium iron phosphate batteries for electric vehicles of the same model as the original battery, and connect them in parallel with this set of unrechargeable batteries, let the good batteries discharge to the unchargeable batteries, and charge them in parallel after several cycles , There is a certain chance to reactivate the battery. The second activation method is to use a small charger to charge the lithium battery pack first, and then change the original charger to continue charging. For example, if the battery that cannot be charged is 60V, you can first charge it with a 48V charger, and then use the original 60V charger to charge it, so there is a certain probability that it can be activated. The third activation method is to try fast charging for one to two hours, and use a professional tester to see if the voltage has risen. If it rises, you can choose to use the original charger to continue charging, so that you can activate the electric vehicle lithium battery. If the lithium battery of an electric vehicle loses more power, it will not be useful if the battery is activated immediately, and the charging problem can only be solved by replacing the battery.
