Will the electric car quickly charge the battery?

I ride an electric car to work every day, sometimes when I go to the middle of the road, I will go to the fast charging station on the side of the road to charge. The voltage displayed on the charging box reached more than 500 volts. I don't know if such charging will have an impact on battery life.

It is very common to have a fast charging station on the street now, and it has also brought convenience to many people riding electric vehicles. However, although the charging effect is good, the charging can run for a long time, but the number of times of charging is increased, and it will cause damage to the battery itself.

The Yangzhou electric vehicle market uses more lead-acid batteries . Generally, lead-acid batteries are charged in two steps. It starts with normal charging and then trickle charging, so that the battery can be fully charged. Trickle charging refers to the continuous small current charging that keeps the battery in an approximately fully charged state, which is used to compensate for the capacity loss caused by self-discharge after the battery is fully charged. However, fast charging does not have a trickle charging process and therefore cannot be sufficient. The life of the battery is greatly related to the number of times of charging. Generally, a battery can charge 300 to 500 times, and the number of times of charging is increased, and the battery life will be exhausted quickly.

In addition, some of the fast chargers are high-current charging, and some are high-voltage charging. The rapid charging causes the battery plate to warp and the acid concentration increases, thereby causing damage to the battery. Moreover, the problem caused by fast charging does not belong to the merchant's three-package agreement, many consumers have eaten dumb losses.

Battery longevity 5 bogey

Do not charge the battery until it is exhausted: the battery is best charged after it is completely used up, otherwise it will speed up the battery attenuation and shorten the life.

If the battery is not full, use it: If this is the case, the battery will produce a kind of “memory”. After that, the battery will not be fully charged, which will affect the mileage and life.

Avoid long-term no need to not charge: the battery will also discharge when not in use, long-term use does not charge the battery, it will weaken the performance of the battery. When not used for a long time, the battery should be charged once every half month or so.

Avoid starting climbing and not assisting: riding in the case of starting, climbing, and heavy load, the discharge of the battery is higher than usual, the current will increase significantly, people are not helpful, it is a kind of damage to the battery.

Avoid exposure to sunlight: If the temperature is too high, the internal pressure of the battery will increase and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the water loss of the battery, and the excessive water loss of the battery will inevitably lead to a decrease in battery activity. Softens, the shell heats up during charging, and the shell is deadly damaged by drums and deformation.
