Will the rapid charging of electric vehicles affect the battery life?

Studies have shown that as the temperature drops, the working hours of electric vehicle batteries are also shortened. This fall, battery charging stations are quietly rising on the streets of Zhucheng. These electric vehicle quick charging stations have solved the trouble caused by the half-way "small picks" of electric vehicles for many citizens, and have been welcomed by many citizens. However, some citizens have reported that such fast charging may have an impact on the life of the battery.

Everyone in the industry has a "degree" fast charge battery

According to Mr. Zhang, an electric car dealer, the electric car is not charging as fast as possible, but the slower the better. The battery life of the electric car battery is two years under normal use. Fast charging will cause the battery plate to warp. The consequences of deformation, acid concentration increase, etc., thus accelerating the aging of the battery and shortening its life.

It is understood that occasional fast charging can improve the activity of the battery, which is beneficial to the battery to a certain extent.

But everything must be mastered by a "degree". Generally speaking, the charger is normally charged, the battery can be used for 2 to 3 years, and the charger current of the fast charging station is nearly 10 times higher, which seriously exceeds the charging load of the electric vehicle battery, which will damage the internal structure of the battery. Therefore, it is recommended that the electric vehicle user should use the special charger provided by the electric vehicle to charge, and choose the fast charging, which is a choice when it is helpless.

It is difficult for the regulatory authorities to damage the rapid charging.

In response to this problem, the relevant person in charge of the Zhucheng Quality and Technical Supervision Bureau said that at present, there is no manufacturer of fast chargers in the city. They are still unable to test the damage caused by the fast charger to the battery of the electric vehicle, so it is impossible to make a conclusion.

The relevant person in charge of Zhucheng City Administration of Industry and Commerce also said that there are very few complaints from consumers about battery damage caused by fast chargers, and they know very little about this situation.

“After charging with the quick charger, the battery cannot be found on the spot. Even if the battery is slow to charge or does not charge in a few days, it is difficult for the owner to find evidence that the battery is damaged by the quick charger. The situation is more difficult to handle." The relevant person in charge said.
