Correct charging method for lithium battery of the electric vehicle.

1, electric car lithium battery charging commonly, had better be in accordance with the specification of above, if not, depends on the capacity of lithium-ion batteries and the current of the charger is how to consider, such as 48V/ 20Ah lithium battery, the charger is 5A, will be a little more than four hours, if it is 10A charger is a little more than two hours, 20A charger is one hour.

2, generally newly bought electric car lithium battery is new, capacity is also large, charging time will be longer, will reach more than 10 hours unchanged lamp, later will be faster and faster, about 2 months later will be reduced to 6 hours, then the constant can last for about half a year, battery capacity will continue to decay, 1 year after 3-4 hours can be full, Of course, the battery should probably be replaced or serviced.

3, after buying a car, lithium battery should have about 80% of the power, should be charged at home, the time is to change the charger lamp and then charge 4 hours is appropriate, so three times.

4, electric car lithium battery charging time should not be too long, in order to change the lamp charger after an hour is appropriate. It's better to undercharge, rather than overcharge,  because otherwise the battery will be charged because of the lack of water, swelling up. Causing irreparable damage to lithium batteries.

5. Swap the monomers in the whole group of electric vehicle lithium batteries, and add 3-4 ml of deionized water to each monomer of the battery after the warranty period for each three or four months.

6. The discharge port and charging port of the whole group of electric vehicle lithium battery should be kept clean at all times to prevent copper rust at the contact point, resulting in overheating and damage due to poor contact.

7. The lithium battery of electric vehicle should be used up before charging for the first time, but not exhausted. Electric cars don't get too full when they're new, but they don't get too low either unless they're old or shoddy. When you use it, you should estimate the distance you can run according to the estimate of the business, so as not to run out of electricity or electricity.

8, lithium battery electric vehicle activation does not need a special method, in the electric vehicle running lithium battery will be activated naturally.

9. A regular deep discharge can also help to "activate" the battery and slightly increase its capacity. The usual method is to discharge the battery completely once in a while.
