What is the repair method of lithium ion battery
The maintenance, repair and reuse of lithium-ion batteries for electric vehicles is completely achievable. From the perspective of the structure of lithium-ion batteries for electric vehicles, lithium-ion batteries for electric vehicles are mainly composed of lithium cells, protection plates and related accessories. Battery failures are problems with no output from the battery, inability to charge the battery, undercharged battery, and low battery life.
Hydrate
Refilling the lithium-ion battery of an electric vehicle that has been used for about 4 months can prolong the service life of the battery by an average of more than 3 months. It should be noted that after each water replenishment, the battery is in an overcharged state to change the battery from a quasi-poor liquid to a poor liquid state, and this overcharge is beneficial to increase the battery capacity.
particle generator
Take the particle generator in parallel with the battery to repair the lithium-ion battery. This method is better for repairing the battery, but because the repair is relatively thorough, if there is no overdischarge, the possibility of battery vulcanization is often completely eliminated for batteries that are continuously used.
Eliminate vulcanization
Use electric vehicle lithium-ion battery repair equipment to eliminate vulcanization of the battery.
regroup
After the whole set of lithium-ion batteries is damaged, we often conduct charge and discharge tests on the batteries. During the inspection, we often find that 50 percent of the batteries in a set of batteries are not damaged. The reason for this is that in a series battery pack, individual batteries lag behind, resulting in a decrease in the function of the entire battery pack, so that the function of the entire battery pack decreases.
comprehensive repair method
The lithium-ion batteries of electric vehicles are regularly inspected, sulfur removal and water replenishment are carried out in time, and a single battery is charged and reconfigured. Battery description, if it is maintenance-free, generally do not add water. If you want to add water, first check the density of the electrolyte of the electric vehicle battery itself, and choose the corresponding concentration or no concentration of water to supplement according to different situations, so as to increase the battery capacity or prolong the service life.
