Q: What are single-phase, two-phase, and three-phase electricity? How can I determine which charging method my vehicle supports?

A:
1.Identification Method (via charging port pins)
Single-phase (1-phase): Pins L2 and L3 are empty (only L1 and N are active).
Two-phase (2-phase): L2 has a pin, while L3 is empty.
Three-phase (3-phase): Both L2 and L3 have pins (L1+L2+L3+N).
2.Charging Power Compatibility:Three-phase chargers are backWard compatible with single/two-phase charging, but the actual power depends on the vehicle's capability.
3.Examples:
If the vehicle only supports single-phase 32A (7kW), even when connected to a 32A three-phase (22kW) charger, it will still charge at 7kW.
If the vehicle supports three-phase charging, it can achieve higher power (e.g., 11kW or 22kW).
