Six maintenance tips for lithium-ion batteries in electric vehicles

Have you ever done the maintenance of lithium-ion batteries for electric vehicles? Electric vehicles are closely related to people’s lives, but if you don’t pay attention to the daily maintenance and maintenance of batteries, your car’s battery capacity will decay very quickly! As long as you pay a little attention, you Will add the life of your car battery, come and take a look at the daily maintenance precautions for electric car batteries: 1. Prevent defective storage: Defective storage means that the battery is not charged in time after use, resulting in insufficient charging and reducing the battery capacity. The longer the idle time in the insufficient state, the more serious the battery damage. When the battery is not in use, charge it once a month to extend battery life. 2. Check regularly during use. If the driving range of the electric bicycle suddenly drops more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has a short circuit, such as a battery rupture or a softened plate. , Active material detached from the board, etc. At this time, the inspection and repair mechanism of professional electric bottles should be reported 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. Lead sulfate is easy to crystallize and damage the physical properties of the battery board. 4. Generally master the charging time, the battery is charged at night, the average charging time is about 8 hours. If there is a slight discharge (after charging) when driving for a short distance), the battery will be fully charged quickly, and overcharge will occur if the battery 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 once when the depth of discharge is 60%-70% (two bars below), and it can be converted to the actual riding mileage according to the actual situation. Charge it when necessary to prevent harmful charging. 5. Prevent high temperature exposure. The high temperature environment will increase the internal pressure of the battery, and the pressure limiting valve of the battery will be forced to open automatically. This is a direct consequence of the newly added battery loss of water, and excessive battery loss will inevitably lead to a decrease in battery activity. The accelerating board softens, the charging shell heats up, and the shell causes fatal damage such as swelling or deformation. 6. In winter, the battery should be warm for two hours, then charge. The car battery will slowly run less and less as time goes by. This is normal, especially the cold. The battery will be charged once when the battery is fully charged, which is the so-called charge. One charge is to wait for the electro-optical charge for about 2 hours to ensure that the battery is fully charged and reach the maximum good mileage. Generally, there is a deep discharge in about two months, and the empty charge can be used to flush the lead deposit. Phenomenon, to improve the battery capacity, the battery is most afraid of being often empty when charging or the lamp has not changed during charging. It will not be enough for a long time about 20 days to charge. The host upstairs said that charging distilled water is personally impossible for you. Because the battery of an electric car is a completely enclosed and maintainable battery, under normal circumstances, you can use it for about 2 years, but it depends on how many miles you have to run every day.
