China is the world's leading producer and seller of electric vehicles. After years of development, the number of second-wheel electric vehicles in China has reached 350 million, with an annual output of more than 35 million, ranking the first year in the world. As a big production country, the electric vehicle penetration rate of our country is very high, almost every household has.

Nowadays, electric vehicles have become an important means of transportation in people's life, occupying an important position in short distance travel. Compared with private cars, electric cars use batteries to drive, no pollution emissions, can be described as economic and environmental protection. However, there is a problem we have to face, that is battery pollution.

Battery is one of the "three big pieces" of electric vehicle, the importance is self-evident. There are many types of batteries on electric vehicles. The biggest use is the valve-controlled sealed lead-acid battery, which has a high cost performance and low cost. In addition, there are many kinds of batteries used in electric cars, such as nickel-metal hydride batteries, nickel-cadmium batteries, lithium-ion batteries and lithium-polymer batteries.

The battery on the electric vehicle is a wearing part. With the increasing use time, some problems also gradually appear. The most common problem is the aging of the battery, which leads to the reduction of the endurance of the electric vehicle.

Now the pace of life in the city is fast, riding electric vehicles to travel, if the battery capacity is less, it simply cannot meet the demand for use. At this time, many people will think of replacing the battery. There's no need to change it.

Do you need to change the battery for electric cars? Here's a trick: Make the battery last 2 years longer.

1, if the endurance of the electric vehicle attenuation is not very serious, that the battery just began to lose water vulcanization, only need to add distilled water or add a small amount of nano carbon battery activator can be recovered.

2, if the range of the electric vehicle attenuation to half of the new car, it means that the battery plate vulcanization is serious, at this time we can use lead-acid battery repair liquid to increase the endurance of the electric vehicle.

3. The range of electric vehicle is shortened to more than half, indicating that the battery is extremely serious vulcanization, and the effect of adding this repair solution is not obvious, so the battery must be replaced.

The method of adding battery repair solution is very simple, generally with a syringe can be completed. First open the exhaust valve of the lead-acid battery, and then according to the amount of repair liquid added, add the liquid to the battery vent. If the battery loses water seriously, we also need to add supplementary liquid to the internal diaphragm of the battery, cover the battery cover and let it stand for 2 hours after the operation is complete. Wait until the added solution is fully integrated with the electrolyte before charging the battery.

Battery water refill operation can use the battery watering gun, can be a key of water refill, water full induction stop, can effectively ensure the consistency of the water level, there is no need to worry about the problem of uneven water. It can effectively improve the maintenance efficiency of water addition and ensure the consistency of battery unit characteristics after water addition and maintenance. Improve battery efficiency and service life.

Electric vehicles do not use for a long time, we should remember to charge the battery, it is recommended to charge and discharge more than 3 times a month. This is because if the idle time is too long, the battery power will be completely exhausted, which will cause the battery to enter the aging state in advance, and eventually lead to reduced battery life. For the maintenance of electric vehicle battery, what is your opinion or view?
