Generally speaking, the battery of the electric car also belongs to the consumables, and its life span is about 2-3 years, some vehicles, although the battery can still be used beyond the use of time, but its riding mileage has been greatly reduced.

The battery of an electric car will shorten the life of the battery if it is not used properly. With the increase in the number of charging and discharging, the performance of the electric car battery will be reduced, the battery is required to be replaced regularly.

The battery is composed of a positive pole, a negative pole, and an electrolyte, and the chemical reaction inside the battery is a reversible reaction, which proceeds in the opposite direction during charging and discharging. The smaller the discharge depth of the battery each time you use it, the longer the service life of the battery, so no matter how large the capacity of the battery pack, you should develop a good habit of charging as you use it, often charging so that the battery is often in a saturated state, as far as possible, not to drive with people, when you meet the slope to push, and try to avoid braking more, more to start when driving.

The service life of the battery of the electric car has a lot to do with the owner's daily use and maintenance, so the owner should pay attention to the daily use of the car to maintain a good electric car, and develop the habit of charging as you go, the battery needs to be placed for a long time in the heart of the first full of electricity and regularly replenish the amount of electricity, generally 1-2 months to replenish.

Electric car battery aging judgment

Electric car batteries after a period of time, there will be a decline in range and not durable, it is necessary to determine whether the electric car battery needs to be replaced, determine whether the electric car battery needs to be replaced only need to look at the following 3 points.

1, the electric car range is less than 10km

Ordinary circumstances, the electric car range is about 40-50km or so, and with the growth of the use of time, the range will also decline, when the electric car range down to 10km or less, then basically can be judged as the battery of the electric car to reach end-of-life state, then need to replace the battery. The battery will need to be replaced.

2, the battery is filled with drums

Secondly, the owner needs to check the battery there is no bulging situation, the battery bulging, generally can not be repaired, can only be resolved through the scrapping of the replacement battery. Check whether the battery is bulging operation is to use a screwdriver to remove the battery, and then observe the battery has no bulging place.

3, whether the battery is aging

The last thing is to check whether the battery is aging, if the battery is aging, then generally there will be deformation or leakage, the user only need to observe the surface of the battery can be. If the battery appears to be deformed or leakage, then it proves that the battery is aging. Then it needs to be scrapped and replaced with a new battery.
