What is the difference between 220v and 380v charging piles?

[LaEllie]

The differences between 220v and 380v charging piles are as follows: Different input and output voltages: AC (220v) charging piles have a single-phase 220V input voltage; the output power is single-phase 220V/5KW; DC (380v) charging piles have a three-phase four-wire 380VAC power input voltage, and the output is direct current, with the output voltage meeting the battery system requirements of the charging object. Different charging methods: AC (220v) charging piles generally have only one charging mode; while DC (380v) charging piles have two charging methods: regular and fast. The regular method is a 5-hour charging mode, and the fast method is a 1-hour charging mode (selected based on different battery types). Different protection levels: AC (220v) charging piles should meet the relevant regulations in the "Low Voltage Distribution Design Specification" (GB/50053); DC (380v) charging piles (plugs) have a protection level that complies with the IP54 requirements of "GB-4208-1993 Enclosure Protection Level (IP Code)".

When driving an electric vehicle in the city, I noticed that 220V charging stations use single-phase electricity, similar to household sockets. The charging speed is slow, taking almost a full night to charge, making them suitable for daily home use or installation in residential parking areas without complex wiring. On the other hand, 380V stations use three-phase electricity with higher power output, commonly found at fast-charging points in shopping malls or highway service stations, capable of charging up to 80% in just half an hour, ideal for long-distance travel. The core difference lies in voltage and current type—380V stations require stronger wiring support, involve more professional installation, and are costlier, but they're extremely practical for urgent needs. Personally, I think if you commute less, 220V is more economical; if you travel frequently, 380V is more convenient. There's also a difference in electricity costs, but safety aspects are similar for both—just choose the right one for your needs.

From a technical perspective, 220V charging piles use single-phase AC power with relatively low power output, typically around 7kW, resulting in longer charging times as the battery gradually fills up. 380V charging piles operate on three-phase power, capable of delivering higher power outputs up to 22kW or more, with greater current flow enabling significantly faster charging speeds. This difference directly impacts charging efficiency - higher voltage allows quicker current transmission, reducing waiting time. However, installation requires three-phase power line support, which may necessitate home electrical system upgrades at higher costs. Personally, I find 380V fast charging extremely convenient for long-distance travel by avoiding prolonged waits, while 220V chargers are more widely available and better suited for fixed parking spots. Both options maintain good safety standards when using certified brands to ensure stability.

When installing a home charging pile, I chose 220V because it's simpler and safer, with lower voltage and less demanding wiring requirements, making it suitable for older residential areas. On the other hand, 380V requires three-phase electricity, necessitating a professional electrician to check if the circuit is compatible, which is a bit more complicated. The main difference lies in charging speed: 220V takes all night to fully charge, while 380V is much faster in public places, saving time but costing more to install. I feel 220V is sufficient for daily commuting; I only seek out 380V stations when in a hurry. Regarding safety, higher voltage may slightly increase risks, but with proper installation, there's no issue. It's advisable to first assess your home power grid.
