Nowadays, every family has electric cars or even more, but many people do not know how to charge. As a result, the battery often fails after buying a new car for a year or two, which is directly related to the fact that they do not know how to charge at ordinary times.

1. After buying the car (or replacing the battery), the battery should have about 80% of the power. When you get home, you should charge it. The time is appropriate to charge the battery for 4 hours after the charger changes the light, which takes three times.

2. In the future, you should insist on charging every day (36v over 10km, 48v over 15km), but the charging time should not be too long, and it is better to change the light of the charger one hour later. When charging, it is better to undercharge rather than overcharge, otherwise the battery will be charged because it will bulge and swell after lack of water. Causing irreparable loss to the battery.

3. Do not allow water to enter the battery box, so as to cause the battery in the housing to be electrified.

4. Fully discharge once a month (ride until the “undervoltage” light is on), and then charge continuously for 12 hours.

5. Conditionally exchange the cells of the whole battery. For the batteries that have passed the warranty period (especially in summer), 3-4 ml of deionized water should be added to each cell every three or four months (Wahaha purified water is also acceptable).

6. Once the charger does not turn green or turns green as soon as it is charged, be sure to check whether there is a problem with the charger or water loss.

7. The discharge port and charging port of the whole set of batteries shall be kept clean at any time to prevent copper rust at the contact point, which may cause overheating and damage due to poor contact.

8. If you have a foot, try to start with your foot. Don’t load too much and accelerate slowly. Don’t start the car with power on.

A group of batteries can be used for more than 5 years with correct charging and normal maintenance. Many users only use 1-2 years to replace them, which is mainly caused by improper charging. Therefore, it is important to master the correct charging method. Remember that the battery is not worn out, but charged.

Before using the electric vehicle for the first time, it must be fully charged for 12 hours and charged frequently. If your car is fully charged and can ride for 100 miles, you must recharge it when you ride for about 70 miles. If you ride 30 miles every day, it will be good and harmless. Under normal conditions (people are not often taken and climbing all day), it is usually best to drive to 60% – 70% of the longest mileage in the manual before charging, which can avoid the early capacity loss of the battery and also avoid over discharge.
