Nowadays, electric vehicles are favored by consumers because of their advantages of being light and pollution-free. The length of the mileage is one of the main criteria for consumers to measure the quality of electric vehicles. The battery is the decisive factor in the length of the mileage. In many complaints about the quality of electric vehicles, the battery problem accounts for more than 95%. What is the problem?
Manufacturers fight prices, reduce battery costs
The batteries used by electric vehicle manufacturers are generally provided by professional battery manufacturers. The quality of batteries produced by different brands and different manufacturers has advantages and disadvantages. Individual manufacturers have reduced the cost and competed in price wars in order to participate in market competition. The direct consequence is that the battery quality is reduced due to cutting corners.
"Three Guarantees" service is not in place
According to the relevant regulations, the battery as the main component of the electric vehicle has a corresponding "three guarantees" period. In the "three guarantees" period, the battery fails, and the producer should bear the corresponding responsibility. In real life, some merchants or manufacturers have no professional knowledge of battery repair, and do not seriously deal with the battery during the "three guarantees" period. Consumers can only change their batteries.
Consumers don't understand the correct way to use the battery
Some consumers use battery methods improperly. First, they charge for a long time. They think that the longer the charging time is, the more electricity they have. The second is that they lose power for a long time and do not charge until they can't run. The third is when the temperature is too high or too low. Under the charge; Fourth, do not pay attention to the regular inspection and maintenance of the battery.
How to charge and discharge correctly
The correct method of use can play a role in extending the life of the battery to a certain extent. Now let's make a brief introduction to the correct method of use:
First, it is not suitable to ride on the charge
The life of the battery is determined by the number of charge and discharge cycles. The more the number of charge and discharge cycles, the faster the life is reduced. Therefore, you should not charge as long as you ride an electric car. You should recharge it when you are 60%-70% of the maximum mileage of the battery.
Second, the charging time should not be too long
Many electric vehicle users believe that the longer the charging time, the more battery power. This is very wrong. The charging time is generally best after extending the lamp for one hour or less. Long-term overcharging can easily lead to battery deformation and water loss. This directly jeopardizes battery life.
Third, it is best to use smart socket
Many electric vehicle users come home from work to charge, and cut off the power when they go to work the next day. In fact, most chargers cannot guarantee 100% automatic power off when the battery is full. The best way is to buy a smart socket and set the time when charging, so that you can solve the problem of rest and rest at night.
Fourth, it is strictly prohibited to exercise at a loss
Some users continue to recharge when the electric car is not riding, which seriously damages the battery performance. Multiple deep discharges can significantly shorten battery life. If the power is not sufficient on the way, it is best to step on the boost in advance to avoid deep discharge.
5. Do not charge if the temperature is too high or too low.
During the charging process, the battery itself generates a small amount of heat, and charging at an excessive temperature causes the temperature of the bottle to rise and impair the performance of the battery. The temperature is too low. Poor battery acceptance, reduced activity, insufficient battery power, increased charge and discharge times, and shortened battery life.
