The AOHAI EV Charger 22 kW 3-Phase is a charging station/wallbox designed for situations where three phases of grid power are available. With 22 kW of charging power, it is suitable for fast AC charging of electric vehicles at home (if equipped with a 3-phase connection), in the office, in apartment buildings, or in commercial settings. It offers powerful charging speeds, smart features, and safety.

Functional features & benefits
Faster charging capacity : at 22 kW the car charges significantly faster than at 7-11 kW, provided the car has an AC onboard charger that supports this.
Using multiple phases ensures better balance in the connection, potentially lower load per phase and reduced cable and house connection problems.
Smart management system : With APP/WiFi/OCPP support, the user can monitor charging status, schedule charging times, set power, and possibly connect to solar power or battery storage.
Safety & reliability : all important safety mechanisms are present to limit risks (short circuit, leakage, overheating, etc.).
Outdoor installation possible : with sufficient IP protection it can be used outdoors or in less than climatically perfect conditions.
Future-proof : suitable for users investing in more charging power now, or homes with three-phase electricity, which also allows for future EVs or higher charging speeds.
