Are AC Charging Piles And DC Charging Piles Charging At The Same Speed?

 What's the difference between the two
The charging pile is a charging facility that "refuels" electric vehicles, and the scientific name is "non-on-board charger". Charging piles are divided into AC charging piles and DC charging piles, so take 7KW as an example: Is the charging speed of 7KW AC charging pile and 7KW DC charging pile the same? What is the difference between the two?
The 7KW AC charging pile is to input the household 220V AC power to the on-board charger. On-board chargers convert alternating current into direct current and feed it into the vehicle battery. if the conversion efficiency of your on-board charger is 90 percent , the output of your charging pile is 7kWh per hour, and the amount of electricity input into the battery is 7kWh per hour×0.{% 7b9}}.3kWh, which is what we usually call 6.3 kWh.
The 7kW DC charging pile directly outputs direct current from the charging pile, and the power is directly input into the battery in the car through the charging gun, without the conversion of the on-board charger. It is equivalent to putting the car charger externally. If the output power of your 7kW DC charging pile is 7kW, then you can roughly equal the power in the rechargeable battery as 7 kWh per hour, which is slightly faster than the AC charging pile. 그러나, compared to the charging time of 7/8 hours, the charging time of these two is relatively close.
the same power and current level conditions, the effect of DC or AC charging is the same.
No matter what kind of charging, for the car power battery, the final input is direct current, AC charging pile is nothing more than AC to DC equipment in the car, and DC charging pile is directly AC into DC charging battery. On-board charger, DC charging pile (Off-board charger), the most intuitive difference between the two is to move the charger from the inside of the car to the 바깥 차!
