How long does it take to charge an electric car battery?

1. After buying a 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 4 hours after the charger is turned on, so it takes three times.

2, after every day (36v ride 10 kilometers, 48v ride 15 kilometers) to insist on charging, but the charging time should not be too long, one hour after the charger is turned on is appropriate. When charging, it is better to undercharge, and do not overcharge, otherwise the battery will be charged because of lack of water, bulging, swelling. It causes irreparable damage to the battery.

3. Do not allow water to enter the battery compartment to cause the battery in the housing to be connected.

4. Completely discharge once a month (ride the “under voltage” light) and then charge for 12 hours.

5, conditional adjustment of the monomer in the whole battery, for the battery after the warranty period (especially in the summer), each 3-4 ml of each cell should be added for each three or four months. Deionized water (Wahaha pure water is also available).

6. Once you find that the charger does not turn green or turn green when you charge, be sure to check if the charger has a problem or lose water.

7. The discharge port and charging port of the whole battery should be kept clean at all times to prevent copper rust from coming to the contact point, resulting in overheating and damage caused by poor contact.

8, as far as possible with the foot to start with the foot, do not load too much, accelerate the gentle. Don't take the car and give it a power start.

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

1, the charging time of the first charge, because the battery car battery is not used at the factory, have not experienced charging and discharging, to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be fully charged, and the subsequent application can be charged a little longer.

2, after the first charge, although it is not the first charge, but the second time is considered a new car charge, this time you can let the battery car run out of power, and then a long time charge, this charge can maintain 8 -9 or even 10 hours, in order to let the battery car chemical reaction for a complete cycle.

3. When the battery car is first charged, the charger may generate heat quickly and the heat is very high. Therefore, especially in summer charging, the charger should not be placed on objects that are prone to heat and burn, and it is best not to put it in the battery car. On the seat, prevent fire.

4. The electric vehicle should run out of electricity before the first charge, but it cannot be used up. When the electric car is newly bought, the power will not be too full, but it will not be too small, unless it is an old battery or a poor quality battery. When you use it, you should estimate the distance that you can run according to the estimation of the merchant, so that you don't have electricity or run out of electricity. When the battery power display has reached the last grid, you should consider not to ride, you have to prepare for charging.

1, charging every day

Even if your electric car lithium battery can be used for 2 to 3 days with a single charge, it is recommended that you charge it every day. Because the used lithium battery in the light cycle, are daily charge will extend the life of lithium batteries of electric vehicles.

2, timely charging

Because the lithium battery will enter the vulcanization process after discharge, if it is charged in time, it can remove the less severe vulcanization. Therefore, the lithium battery should be charged as soon as possible after use, so that the battery is fully charged.

3, regular deep discharge

Regular periodic discharge of the battery also facilitates "activation" of the battery, which can slightly increase the capacity of the battery. The general method is to periodically discharge the battery completely.

The method of full discharge is to ride to the first under voltage protection under normal load conditions on a flat road.

After the battery is under the first under voltage protection, after the battery has passed for a period of time, the voltage is restored to the non-under voltage state. At this time, the battery is fully charged, which will increase the battery capacity.

It should be noted that when the lithium battery is under voltage protection for the first time, please remember not to use the battery. At this time, the damage to the lithium battery is very large.

4, try to use the original charger

In general, chargers from various manufacturers generally have individual needs, so don't change the charger when you are not sure. In addition, do not remove the controller's speed limit, remove the controller's speed limit, although it can improve the speed of some cars, but will reduce the battery life.

In fact, the correct use of electric vehicles lithium batteries. When you buy an electric car, there are usually instructions for use. For your electric car lithium battery can live longer, Xiao Bian reminds you that you must follow the correct use of electric vehicle lithium battery, do not overcharge or over discharge lithium battery.

Every time charging should be 40%-60%, the charging is most reasonable. The battery with charging time of 12AH is 5-8 hours, the battery of 17-20AH is 8-12 hours, and the size can't exceed 12 hours. The first time peacetime, there is no saying. Do not charge 2-3 times a month for a long time.
