Dongzan teaches you how to charge and extend the life of high-capacity lithium batteries for electric vehicles?

1. Place and recharge: The high-capacity lithium battery pack has a part of the remaining power before the original factory. After the electric vehicle is sold, it can also be used for short-distance riding. After the first ride, the battery must be recharged for the first time. Charging, it is recommended that the initial charging should be carried out for a long time (8-12 hours).

The lithium battery pack should be charged immediately after use and cannot be stored with a loss of power. If the battery has been left unused for more than 2 months, the high-capacity lithium battery pack needs to be fully charged. If it has been left unused for more than 5 months, The high-capacity lithium battery pack needs a battery charging cycle. Use the battery regularly and everything will work normally. Regularly charging the lithium battery pack when it is left for a long time can ensure the best use effect of the high-capacity lithium battery, and Increase usage period.

2. Normal charging: first connect the charging head to the battery pack, and then connect the charging head power cord to 220V AC.

The battery charging time of an electric vehicle should basically be controlled within 10 hours. Charging the battery for too long can easily damage the rechargeable battery. Each time the battery is charged, it should be charged before the battery is used up, so that charging is beneficial. The battery is less harmful and has a longer service life. High-capacity lithium batteries need to be fully charged when charging. When the red light on the charging head lights up, it means that the high-capacity lithium battery has entered the constant voltage float state. Charging status, it does not mean that the high-capacity lithium battery is fully charged at this time (about 70-80% charged).

3. Choose a high-capacity lithium battery charger: Because lithium batteries use constant voltage charging, lead-acid batteries use constant current charging. High-capacity lithium batteries for electric vehicles cannot be charged with a lead-acid battery charger, otherwise the battery will be damaged. The size of the electric vehicle charger must be consistent with the size of the high-capacity lithium battery to be used. Mismatching will cause greater damage to the high-capacity lithium battery and can easily cause safety risks.

4. Pay attention to daily maintenance: when riding uphill, you don’t just rely on electric power to go uphill, but also need to cooperate with the pedals for assistance; on the other hand, even if you don’t need to use it for a long time, you only need to charge the battery once every half a month. In this way, It can extend the service life of high-capacity lithium batteries. On the other hand, the tires must be inflated and the power switch must be turned off immediately when getting off the car.
