How Many Kilowatts for a Car Charging Pile?
2 Answers
Charging piles are generally divided into two types: AC piles and DC piles. AC Pile: Typically, the standard is 7KW. Some manufacturers provide portable chargers or three-prong cables with only 2-3KW when purchasing a car, which are not standard piles. DC Pile: Also known as fast-charging piles, they usually come in 15, 20, 30, 45, 60, 100, 150, 200, 250, and 300KW. Charging Time: The charging time for a car depends on the battery capacity of the vehicle. Generally, small and medium-sized electric vehicles can hold up to 18 kWh when fully charged. Current Consumption: To calculate, you need to know the input voltage and current of the charger. Moreover, during charging, the current consumption of the charger constantly changes and does not remain at a fixed value. The calculated result is only a reference value.
I personally think it's quite important to distinguish between home chargers and public chargers. The most common home charging piles are 7kW, plugged into 220V electricity, which can basically replenish 500 kilometers overnight; if you have three-phase electricity, you can also install an 11kW one, which can increase the charging speed by 30-40%. Fast charging piles in shopping malls generally start from 60kW, and the supercharging piles in service areas can now reach 120kW or even 180kW, allowing you to replenish 200 kilometers in the time it takes to drink a cup of coffee. Tesla supercharging stations even go up to 250kW, allowing you to charge more than half in 20 minutes. However, the actual power depends on the car, as many domestic electric vehicles only support up to 80kW, so larger charging piles can't be utilized.
