The AOHAI EV Charger 22 kW 3-Phase is a charging station/wallbox designed for situations where three phases of mains power are available. With 22 kW charging power, it is suitable for fast AC charging of electric vehicles at home (if equipped with a 3-phase connection), at the office, in apartment complexes, or in commercial settings. It offers powerful charging speed, smart features, and safety.
Technical Specifications (Expected / Typical)
| Specification | Typical Value |
|---|---|
| Rated Power | 22 kW AC (three-phase) |
| Connection / Grid Type | 3 phases + N + PE (Three-phase AC connection, usually ± 400 V) |
| Maximum Current per Phase | 32 A (or sometimes 16 A depending on the setting) |
| Voltage | ± 400 V AC ± tolerance (often ±10–15%) |
| Frequency | 50 Hz (sometimes 50/60 Hz compatibility) |
| Connector / Plug | Type 2 plug or socket (depending on version) |
| Protection Class | IP rating between IP54 and IP66 (for outdoor use, splash water/dust resistant) |
| Operating Temperature Range | Approx. –20 °C to +50 °C (or slightly higher depending on brand / environment) |
| Communication / Interface | Possibly via WiFi, Ethernet / LAN, Bluetooth; possibly OCPP protocol for network management, app control, RFID or card readers for access |
| Safety Features | Overcurrent protection, overvoltage/undervoltage monitoring, residual current devices (residual current detection), short-circuit and high-temperature protection, possibly ground-fault detection |
| Mounting Type | Wall mounting; possibly also pole mounting (column) depending on design & application |
| Physical Dimensions / Weight | Moderate size — weight usually between 7-15 kg, robust housing (metal / reinforced plastic parts) |
Functional Features & Benefits
-
Faster charging capacity: with 22 kW, the car charges significantly faster than with 7-11 kW, provided the car has an AC on-board charger that supports this.
-
Use of multiple phases ensures better balance in the connection, potentially lower load per phase, and reduced cable and home connection issues.
-
Smart management system: with app / WiFi / OCPP support, the user can monitor charging status, schedule charging times, set power, and possibly connect with 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 not-climatologically perfect conditions.
-
Future-proof: suitable for users who are currently investing in more charging power, or homes with three phases, allowing for future EVs or higher charging speeds.
The integrated EMS automatically optimizes consumption, storage, and grid load. In the event of a power outage, the system switches to backup power within ≤10 ms.
With a built-in EMS (Energy Management System), support for peak shaving, and flexible charge and discharge settings, energy balance is automatically adjusted to consumption, grid status, and storage.
With an IP66 enclosure, silent passive cooling, and real-time monitoring via app or WiFi, the inverter offers reliability, ease of use, and minimal maintenance requirements.
- Businesses may need to employ various types of legal pages on their websites or mobile apps. Some, like Privacy Policies, are required by law, while others, such as a Terms and Conditions agreement (T&C), are not. Regardless of legal demands, you may find that your company needs one or more legal pages for compliance and optimal operation.
- In this article, we will go over the most common legal pages, walk you through a summary of what each requires, and explain why you may need it. In addition, you'll find a sample template for each type of legal page so you can quickly get started writing your own.
If you still have any questions you would like answered, you can fill out the questionnaire below and we will answer as soon as possible!
