Electric vehicle lithium battery maintenance guide can be used for several years

In the field of electric vehicle batteries, lithium batteries are favored by consumers with their high energy, small size and light weight. This issue of information for friends to provide some lithium battery use and maintenance of dry goods guide.

1, in the process of riding an electric vehicle, do not wait until the lithium battery is under voltage to charge. The greater the depth of discharge, the more times the battery is used, the shorter the service life of the lithium battery, and the lithium battery of the electric vehicle should be shallow charged and shallow discharged.

2, prohibit lithium batteries for a long time idle and loss of power storage. If the lithium battery is not used for a long time and does not charge, it will lead to the battery "starving to death", the battery capacity will be greatly reduced, the battery is not used for a long time, should only leave half the power, do not be fully charged (fully charged battery fluid is more active and easy to "full death"), and do not have no power for a long time.

3, lithium batteries can be charged at any time, but there is no memory effect. If it is found that continuous charging exceeds the battery capacity ÷ charger output current = quotient ≥1 hour after the lamp has not turned, (such as the battery capacity is 20 amp, the charger output current is 2 amp, 20 amp capacity ÷2 amp output current =10 hours, charging for 11 hours, the charger has not turned full of lights, should immediately stop charging), and check whether the battery temperature is too hot, If it is too hot, it should be checked and repaired as soon as possible.

4, high temperature environment, charging reaction speed will be faster, so try to avoid charging in direct sunlight or outdoor exposure.

5, rainy days riding electric vehicles or parked in the open environment, electric vehicles are easier to water, resulting in motor and controller failure, reduce the life of the battery, lithium batteries are first afraid of water, water will lead to battery short circuit rust; The second fear of collision, lithium batteries are relatively fragile, collision will lead to changes in the internal structure of lithium batteries.

6, lithium battery electric vehicle users should know to cherish the battery, do not large current discharge, start slowly do not add the switch, which can effectively extend the battery life.

7, the lithium battery has just run out of riding, should be shelved for about 20 minutes and then charged, should ride the battery, the internal battery fluid is more active, immediately charging will also lead to shorter life.
