What is the power of a 380V charging pile?
3 Answers
380V charging piles typically have a power of 40KW. Charging piles are generally divided into two categories: AC piles and DC piles. The time required to fully charge a car depends on the battery capacity of the vehicle. To calculate the charging time, it is necessary to understand the input voltage and current of the charger. Moreover, the current consumption of the charger continuously varies during the charging process and does not remain constant, so the calculated result is only a reference value. Below is some relevant knowledge about charging piles: 1. AC piles: The standard power is usually 7KW, but some manufacturers provide portable chargers or three-prong cables with only 2-3KW, which are not standard piles; 2. DC piles: Also known as fast-charging piles, they typically have power ratings of 15, 20, 30, 45, 60, 100, 150, 200, 250, and 300KW. Currently, most DC piles use modular power combinations, offering more flexible benefits and allowing users to freely combine the power of the charging pile according to their needs.
I just installed a 380V charging station with variable power, typically ranging from 7kW to 22kW. Ours is 11kW, which charges much faster than standard 220V—it only took about 4 hours to fully charge an electric car. If the power is lower, say 7kW, it’s still usable, but commercial-grade 22kW is more time-efficient. The circuit had to be upgraded during installation to avoid tripping; our electrician added new cables, costing over a thousand yuan. It’s incredibly convenient in practice, especially charging overnight—the car is fully charged by morning. Just be mindful of stability; voltage fluctuations in summer can affect efficiency, but regular checks on the connections keep things smooth. Overall, 11kW strikes a good balance.
As an enthusiast, I know that 380V refers to three-phase electricity, and power calculation is related to current. For example, a common 11kW charger has a current of about 16 amps; for a 22kW charger, it can reach 32 amps. The higher the current, the faster the charging—a 22kW charger is nearly twice as fast as an 11kW one. However, you must ensure that your home's electrical panel has sufficient capacity. An 11kW charger is usually enough for an average household, but exceeding that may require applying for an upgrade. Voltage fluctuations affect efficiency—I've measured my home charger with a multimeter, and as long as it stays stable at 380V, there's no issue. I recommend using a smart charger with an app for monitoring to avoid overloads or malfunctions. Don’t overlook routine maintenance—regularly cleaning dust from the plug can extend its lifespan and save you some hassle.
