Why don't electric cars recommend fast charging?

Speeding is very harmful to the battery. Generally, the current with the charger is about 1.8-2A, and the current of the rapid rush is 9-11A, so it will be very hurt. The principle of the electric vehicle fast charging station is that the current of the fast charging station is about 9A, and the small current is almost 0.5A. However, the household current is about 1.5A-2A, so the current in the home is too low. If the current is low, the charging will be slow, so the low current in the home cannot be quickly charged.

Slow charging of electric vehicles often lasts for more than 6 hours, so in order to slow down, it is often necessary to stop charging overnight. In fact, slow-charge batteries are also recommended by people with experience in the electrochemical industry. It is simple to say that fast charge is very demanding on the quality of the battery, and the reaction conditions of the battery under high current are too harsh and severe, and deviate from equilibrium. Farther, there is a large loss of battery life, the safety factor will be significantly reduced, so do not do as little as possible.

Electric cars are charged at a faster rate. Of course, here, how fast is the fast charge, and how fast is not between the two, I am afraid there is no clear distinction. AC charging generally refers to the way in which single-phase or three-phase AC power is converted to a suitable voltage by means of rectification, filtering, and power factor correction by a charger in the vehicle to charge the power battery.
