What is the power of a 380V charging pile?
3 Answers
380V charging piles have a power of 40KW. Charging piles are generally divided into two types: AC piles and DC piles: 1. AC piles: Typically have a standard power of 7KW, though some manufacturers provide portable chargers or three-pin cables with only 2-3KW, which are not standard piles; 2. DC piles: Also known as fast-charging piles, usually come in power ratings of 15, 20, 30, 45, 60, 100, 150, 200, 250, and 300KW. Most DC piles now use modular power combinations, offering more flexible benefits and allowing users to freely configure the charging pile power according to their needs. Additional information: The time required to fully charge a car depends on the battery capacity. Generally, small and medium-sized electric vehicles can hold up to 18 kWh of electricity. To calculate the charging time, it's necessary to know the input voltage and current of the charger. However, the current consumption of the charger varies during charging and does not remain constant, so the calculated result is only a reference value.
I use a 380V charging station with 22kW power, and this power selection should be based on the size of the electric car's battery and daily driving distance. For example, if I drive a Tesla Model 3, if the power is too low, it won't be fully charged overnight and won't be usable the next day. 380V represents three-phase electricity, which is common in homes or shopping malls, and the power is not a fixed value; it ranges from 11kW to 50kW. 11kW is suitable for ordinary household electric cars, as it can fully charge overnight, while 22kW or higher is suitable for commercial use or models with frequent travel. When I installed it, I chose 22kW because the current demand was a bit higher, and I had to ensure circuit safety—the home wiring had to be upgraded to three-phase 16A or above. High-power charging is faster, but the electricity cost is also slightly higher. In actual use, I found that charging stations with power exceeding 20kW generate more heat, so better heat dissipation is needed; otherwise, efficiency decreases. In summary, 11kW is generally recommended as a starting point, and the most suitable option should be chosen based on the vehicle's manual and safety regulations.
When selecting a 380V charging station, the power typically ranges from 11kW to 50kW. I recommend starting with household needs. If the community allows the installation of three-phase electricity, prioritize checking the current in amperes: 16A corresponds to 11kW, and 32A corresponds to 22kW, which directly affects charging efficiency. From my experience, higher power means shorter charging times, but you must consider electrical capacity and cost. A friend of mine installed an 11kW unit and saved a lot on electricity bills over a year; I chose a 22kW one, which takes about three hours to charge a 70kWh electric car from zero to full. During installation, pay attention to matching the power with the type of electric vehicle. For example, vehicles with longer ranges are more suitable for high-power charging, but don’t exceed the community grid limits. Power also affects equipment lifespan; high-power charging stations require regular maintenance to reduce overheating issues. Safety first—consult with property management and electricians to ensure everything complies with regulations.
