How to maintain and repair lithium batteries for electric vehicles?

How to maintain and repair the lithium battery of electric vehicles? The sun does not charge in summer. All electric vehicle batteries should be charged frequently. The charging time is not too long, no more than 12 hours. Pay attention to heat dissipation. In addition to the depth of discharge and life are closely related, It is how much power you have inside the battery, which is why you often charge. Note: It is strictly forbidden to store the battery in a lost state. Defective state means that the battery of an electric vehicle is not charged in time after use. Vitrification is prone to occur when the battery is in a de-energized state. Lead sulfate crystals adhere to the electrode plates, blocking ion channels, causing insufficient charging and reducing battery capacity. The longer the battery standby time, the more serious the battery damage. Therefore, when the battery is not in use, it should be replenished once a month to keep the battery healthy. When the electric vehicle starts, carries people, or climbs a mountain, please use your feet to push the power, and try to prevent instantaneous large current discharge. High current discharge can easily lead to lead sulfate crystallization and damage the physical properties of the battery panel. Electric cars cannot be parked outside when it rains, because rain can easily lead to paralysis and breakdown. It is not conducive to battery maintenance. During use, if the mileage of an electric vehicle suddenly drops by more than 10 kilometers in a short time, it is likely that the grid of at least one battery in the battery pack is broken, the electrode plate is softened, and the active material of the electrode plate is short-circuited. At this time, you should go to a professional battery maintenance organization for inspection, repair or grouping in time. This can relatively extend the service life of the battery and save energy to the utmost extent. Pay attention to the quality of the charger at any time, so as not to have a certain impact on the maintenance of the electric vehicle and the combustion of the battery. 1. Prevention of power loss and storage: Power loss refers to the fact that the battery of an electric vehicle is not charged in time after use, resulting in insufficient charging and reducing battery capacity. The longer the battery standby time, the more serious the battery damage. When the battery is not in use, charge it once a month to extend battery life. 2. Periodic test During use, if the range of the electric bicycle suddenly drops more than ten kilometers in a short period of time, it is likely that at least one battery is short-circuited in the battery, such as broken grids, softened plates, and plate active materials. At this point, you should go to a professional battery repair organization for inspection and repair in time. Do not discharge electric bicycles when starting, carrying people, or going uphill. It is best to use pedals as power to prevent instantaneous discharge of large currents as much as possible. High current discharge may cause lead sulfate to crystallize, thereby destroying the physical properties of the battery panel. Electric vehicle batteries are generally charged at night, and the average charging time is about 8 hours. If the battery is slightly discharged (the mileage after charging is very short), the battery will be fully charged soon, and the battery will be overcharged if it continues to be charged, which will cause the battery to heat up and reduce the battery life. Therefore, it is best to charge the battery of an electric vehicle with a depth of discharge of 60%-70% (the following is two cells), which can be converted into riding mileage in actual use. The necessary charging can be carried out according to the actual situation to prevent harmful charging. 5. Prevent high temperature exposure. The high temperature environment will increase the internal pressure of the electric vehicle battery, and the pressure limiting valve of the battery will be forced to open automatically. The direct result is the addition of water loss in the battery, and excessive water loss in the battery will unpreventably lead to fatal injuries such as the decrease of battery activity, the softening of the acceleration plate, the heating of the casing, and the deformation of the casing drum. 6. In winter, the battery of an electric vehicle should be kept warm for two hours before charging. The use time of electric vehicle batteries is not much slower in Vietnam. This is normal. It is cold. The battery is the most common at 70-80% of the electricity. The so-called full charge is about 2 hours after the light changes, so The battery is floating, the best mileage, generally about two months, there can be a deep discharge charge, the air can be used to wash the lead precipitation phenomenon, and the capacity of the battery can be improved. The electric vehicle battery is often not replaced or charged before being charged. The lamp is enough to charge if it is not used for about 20 days for a long time.
