Description
Smart, Flexible EV Charging for Your Home
Take control of everyday electric vehicle charging with the Vorsprung Alpha Max 7.4kW Untethered EV Charger.
Designed for homes and suitable business installations, this smart charging unit combines adjustable power, convenient smartphone controls and an untethered Type 2 socket.
Whether you’re upgrading an existing charging point or planning your first home EV charger installation, the Alpha Max provides a practical solution for electric and plug-in hybrid vehicle owners.
Untethered Design for Greater Flexibility
Unlike tethered EV chargers, the Vorsprung Alpha Max Untethered model does not have a permanently attached charging lead.
Instead, it features a Type 2 socket that connects to a compatible detachable charging cable.
This provides several practical benefits:
- Keep the charging point tidy when not in use.
- Use a suitable cable length for your parking arrangement.
- Replace or change the charging cable separately.
- Support different compatible vehicles using the appropriate cable.
A separate charging cable is required.
Up to 7.4kW Home Charging
The Alpha Max provides charging output of up to 7.4kW using a suitable single-phase electrical supply.
Adjustable power settings between 3.7kW and 7.4kW allow charging to be configured to the needs of the installation.
Compared with charging through a standard domestic three-pin socket, a dedicated 7.4kW home EV charger can significantly reduce charging time.
Actual charging performance depends on your vehicle, electrical supply and installation settings.
Smart Charging with the Powerverse App
Manage charging sessions using the compatible Powerverse smartphone app.
Smart functions include:
- Scheduling vehicle charging sessions
- Monitoring charging activity
- Tracking electricity consumption
- Managing charging times around off-peak electricity tariffs
- Adjusting supported charger settings
These features make the Alpha Max a convenient choice for EV owners looking to manage their charging routine and electricity costs.
Wi-Fi and Ethernet Connectivity
The charger supports both Wi-Fi and Ethernet connections for smart charging functions.
Its OCPP 1.6J compatibility also enables communication with supported charge point management systems.
Secure Charging with RFID Access
Two RFID cards are included to help manage access to the charger.
Authorised users can start and stop compatible charging sessions, making RFID access useful for shared driveways, business premises and other locations where charging access needs to be controlled.
Built-In Electrical Safety Features
The Alpha Max incorporates multiple protective functions designed to support safe EV charging.
These include:
- PEN fault protection
- DC leakage detection
- Type A RCD protection with 6mA DC detection
- Overcurrent protection
- Overvoltage and undervoltage protection
A qualified electrician should assess the electrical installation and confirm the required protection and compliance arrangements before installation.
Weather-Resistant Construction
The IP55-rated enclosure offers protection against dust and water ingress, making the charger suitable for appropriately installed indoor and outdoor locations.
Its compact wall-mounted design provides a practical charging solution for domestic driveways, garages and suitable commercial parking areas.
Compatible with Type 2 Electric Vehicles
The Alpha Max features a Type 2 charging socket, which is widely used for AC charging on electric vehicles sold in the UK.
For vehicles with a Type 1 inlet, compatibility depends on using a suitable and correctly rated Type 2-to-Type 1 charging cable.
