How to maintain the lithium battery of electric vehicle?

The sun does not charge in summer, all electric car batteries should be often charged, charging time is not too long, no more than 12 hours, charging attention to heat dissipation, in addition to the depth of discharge and life is closely related, is how much power you have in the battery, which is often let you charge the reason.

Note: Do not leave the battery in the lost state during storage. Defect state is when the battery of an electric vehicle is not charged in time after use. When the battery is in a state of loss of power, it is prone to vitrification. Lead sulfate crystals stick to the electrode plate and block ion channels, resulting in undercharging and reducing battery capacity. The longer the battery standby time, the more serious the battery damage. Therefore, when the battery is not used, it should be replenished once a month to keep the battery healthy. When the electric vehicle starts, carries people or climbs a mountain, please push the power with your feet to prevent instantaneous large current discharge as far as possible. High current discharge can easily lead to lead sulfate crystallization and destroy the physical properties of the panels.

Electric cars cannot be parked outside when it rains, which can easily lead to paralysis and breakdown. This is not conducive to battery maintenance. In the process of use, if the driving range of the electric vehicle suddenly drops more than 10 kilometers in a short time, it is likely that at least one grid of the battery pack is broken, the plate is softened, and the active material on the plate is removed from the short circuit phenomenon. In this case, should be timely to professional battery maintenance institutions for inspection, repair or grouping. In this way, the battery life can be relatively extended and the energy can be saved to a greater extent.

Always pay attention to the quality of the charger, so as to avoid certain impact on the maintenance of electric vehicles and battery combustion.

1. Prevent power loss storage: power loss refers to that the battery of an electric vehicle is not charged in time after use, resulting in insufficient charge and reducing the battery capacity. The longer the battery standby time, the more serious the battery damage. Extend battery life by charging it once a month when it is not in use.

2. Regular testing in the process of use, if the electric bicycle range suddenly falls more than 10 kilometers in a short time, it is likely that there is at least one battery in the battery short circuit, such as broken grid, softening plate, plate active material. At this point, should be timely to the professional battery maintenance institutions for inspection, maintenance.

3, electric bicycle in starting, manned, uphill do not discharge, it is recommended to pedal as power, as far as possible to prevent large current instant discharge. High current discharges may cause lead sulfate to crystallize, thus damaging the physical properties of the panels.

4. Electric vehicle batteries are generally charged at night, with an average charging time of about 8 hours. If there is a slight discharge (a very short driving distance after charging), the battery will soon be full, continue to charge will appear overcharge phenomenon, resulting in battery heat, reduce battery life. Therefore, it is recommended to charge the electric vehicle battery with a discharge depth of 60%-70%(two grids below), which can be converted into cycling miles in practical use. Necessary charging can be carried out according to the actual situation to prevent harmful charging.

5. Protect against heat exposure. The high temperature environment will increase the internal pressure of the EV battery, forcing the battery's pressure limiting valve to open automatically. The direct result is the increase of battery water loss, and excessive battery water loss will inevitably lead to the decline of battery activity, accelerated plate softening, shell heating, shell drum deformation and other fatal injuries.

6. In winter, electric car batteries should be kept warm for two hours before recharging.

The use time of electric vehicle battery is not much slower to run, this is normal, cold days, the battery in 70-80% of the electricity is common, the so-called full charge, is light changes and so on the following 2 hours or so, so the battery floating, better mileage, generally about two months of time, you can have a deep discharge charge, you can use air to flush the lead precipitation phenomenon, improve Battery capacity, electric vehicle batteries often even before charging without replacing the empty or charging lamp, long-term use of about 20 days is enough to charge.
