Fast charging is a method of supplementing electricity that most Oil Electric Hybrid Sedan owners will use, especially for car owners who do not have a personal electric pile at home. Public fast charging piles are almost their only choice.
Will fast charging damage the battery and affect the cruising range of the vehicle? Recently, the editor has been asked this question frequently. I specifically consulted the old driver of the United Oil Electric Hybrid Sedan. Today I will explain it to you.
Batteries have their own service life, that is, the number of charge and discharge times. From the above news, we can see that fast charging has little effect on the battery pack after practice. The specific charging principle will not be explained in detail today, and the conclusion will be directly drawn .
When the Electric Car is charging, the battery management system BMS on the Electric Car will estimate the state of charge of the power battery pack, automatically adjust the charging current according to the condition of the battery pack, ensure that the SOC is maintained within a reasonable range, and prevent overcharging or overcharging. Discharge will damage the battery, so there is no need to worry too much about the damage to the battery caused by fast charging.
When many people use fast-charging charging piles, they only need to fully charge the car before they are at ease. In fact, this concept is wrong.
Car owners should know that when car companies promote Oil Electric Hybrid Sedan, when it comes to fast charging, they basically charge to 80% in half an hour. Why don't they say the full time?
Because the fast charging strategy is to start trickle charging after the maximum current is charged to 80%, and the current will become smaller and smaller. This is to prevent the battery from overcharging and take cautious measures.
Therefore, when you use public fast charging piles, it is best to draw the gun and leave after charging 80%. After all, the efficiency of the latter 20% will decrease and the time will not be wasted.
