First of all, we all know that the working principle of electric vehicle fast charge and slow charge is not the same, fast charge is mainly charged with DC voltage, in this case, DC voltage is greater than the actual battery voltage, a large number of current ions will also flow from the positive electrode to the negative electrode at a very fast and very efficient speed, so as to complete the process of fast charge. That is, in the case of long-term fast charge, the actual battery voltage is very high, in such a high voltage state, will certainly be affected.
Secondly, if you choose fast charge for a long time or frequently, the current or voltage requirements for the battery will be very high, the temperature of the battery pack will also increase, and the speed of battery decay will be very fast under long-term high temperature. The battery can be used for 10 years, and the long-term choice of fast charge may only be used for seven years or even shorter time. Attention should also be paid to charging and maintenance.
Of course, fast charging and slow charging of electric vehicles should be selected according to our daily needs, when the time is relatively tight and the car is in a hurry, you can only choose fast charging, but in the normal life of the car, we still choose slow charging, protect the battery in the range that the battery can withstand, and increase its service life.

All in all, the electric vehicle fast charge for the battery is a certain harm, we in the usual use process, try to let the battery in a relatively mild state, the normal receiving current and voltage, the temperature is stable, so as to extend its service life, reduce unnecessary losses.
Electric vehicle fast charging, first of all need to determine whether the battery has to withstand the function of fast charging. If the battery is to withstand the fast charging function, then such a battery car fast charging is reliable. If the battery does not withstand the fast charging function, then such a battery car fast charging is not reliable, because it will lead to a shorter battery life.
Battery car fast charge is still very reliable, and we have a store that sells battery cars, his door put a battery car fast charge ah, as long as 15 minutes can run a long distance, it is recommended that we usually battery car is best to use less of this kind of fast charge well, often use this kind of fast charge for our battery car is very bad
