What should we do if the battery of the battery car is aging?

Electric vehicles are generally household vehicles, but we often encounter the phenomenon of aging of electric vehicles. For example, it is full of electricity but not far away. This situation is very irritating, so what can we do?

First, let's first check if your electric car battery is still under warranty. Generally speaking, the normal service life of a battery is about 3-8 years. According to the actual situation, generally one battery can use 3 -- 4 years or more is already very good. If the battery expires, it means that the battery is aging, so it is necessary to replace the battery in time.

Second, if the aging is not serious, we can add some distilled water to repair the aging battery, the specific method is as follows:

1. Open the battery cover and remove the 6 helmets.

2. Fill each well with distilled water with a syringe. If 1.28electrolyte is added, the plate may burn out due to excessive acid solubility. For example, when we eat hot pot, why do we eat more salty? That is to say, when water evaporates, salt does not evaporate through water vapor. For the same reason, the acid in the battery will not be evaporated. It's water evaporated, so we just need to add about 20-30ml of distilled water to each well.

3. After filling up, let the battery stand still for half an hour, so that the sponge around the plate fully absorbs water. Then use the resistor discharge to discharge all the electricity in the battery. If there is no resistance, you can use a 12v bulb instead. For example, motorcycle headlights and car turn signals can be used as long as they can discharge to 0v. . How to judge that the battery is almost out of power, the cement resistor is discharged at the beginning of the resistor body, slowly and gradually not hot, then the battery will be out of power. If the light bulb is too direct, as long as the light is slowly turned off, it means that the battery discharge is over. The discharge time depends on the capacity of the battery when it is discharged. We can first maintain the battery when it is not powered. This can shorten the discharge time.

4. After the discharge is finished, the battery is charged. The pulse charging method can be used under the condition that the pulse charging method can effectively remove the vulcanization of the electrode plate and improve the capacity of the battery. Nothing can be replaced by a car charger.

5. After charging is completed, use a syringe to withdraw excess water from each well. A total of 6 holes, completed step by step.

6. Cover the hat and cover, you can use the car.
