Electric vehicles must be equipped with a power battery, which must be charged by means of a charger. Electric passenger cars are generally equipped with on-board chargers. The on-board charger is docked with the AC charging gun, but based on the charging safety regulations, the power cannot be higher than 7kW, that is, it can only be charged 7 kWh in an hour, that is, if the electric car is equipped with a 70-degree battery, it must be charged for 10 hours to complete. This time is too long, and in layman's terms, this is slow charging.
Fast charging, the charger is on the ground, the current power has reached 350kW, and the current charging time for electric vehicles is within 20 minutes, which can be basically completed. In layman's terms, this is fast charging.
Fast charging is conditional:
First, electric vehicles are equipped with power batteries with too small capacity and can only be charged slowly, such as some plug-in hybrid vehicles;
Second, the power battery can accept high-power charging, such as lithium iron phosphate and ternary batteries currently equipped;
Note: The difference between a slow charging pile and a fast charging pile, there is no charger inside the slow charging pile, and there is a charger inside the fast charging pile.
