START CHARGING

Option 1. Plug and Charge

1. Insert the charging plug into the EV

2. Charging session starts

Option 2. Using a RFID card (Optional- Depends on the charger/location settings)

1. Insert the charging plug into the EV
2. Tap the RFID card on the charger
3. Waiting for authorization
4. Charging session starts

STOP CHARGING

1. Unplug any time (disconnect the charging plug from EV to stop charging session)
2. Session ended (please return the connector to the holster)

 LOCKED CONNECTOR

In some cases, the EV locks the connector. To unlock the connector, it may be necessary to unlock all doors of the EV, or use the ‘unlock charge connector button’ on the car key, if present.

 STOP

Charging will stop without user interaction:

• In case of alarm/hazard. 
• When the battery is full, the charge session stops automatically.
• When the maximum charge time set by the operator/owner has been reached.

ABOUT THE ZEROVA AX SERIES

The Zerova AX Series is a line of Level 2 AC EV chargers from Zerova Technologies, a subsidiary of Phihong Technology, a Taiwan-based power electronics manufacturer. The AX Series includes two models for the North American market: the AX48, delivering 11.5 kW at 48A, and the AX80, delivering 19.2 kW at 80A. Both models use a SAE J1772 Type 1 connector, compatible with all Level 2 AC-capable electric vehicles in North America.

The chargers are housed in an IP56/NEMA 4-rated enclosure, providing protection against dust and water ingress for both indoor and outdoor installations. The operating temperature range of -30°C to +50°C (-22°F to +122°F) makes the AX Series suitable for year-round deployment in Canadian climates. A 5-inch LCD display provides real-time charging status, and the compact wall-mounted design supports flexible installation across commercial, fleet, residential, and public charging environments. Cable lengths are available in 5 metres standard, with a 7.5-metre option available with optional cable management, giving installers flexibility to reach the vehicle charging socket at a variety of parking configurations.

SMART CHARGING, CONNECTIVITY, AND USER AUTHENTICATION

The Zerova AX Series supports three methods of user authentication: plug-and-charge (auto-start on plug-in), RFID card, and QR code via smartphone. QR code access does not require a dedicated app, making it straightforward for EV drivers at workplace or public charging stations to start a session without pre-registration. RFID cards link to driver or fleet accounts, supporting access control and session-level billing management.

For network integration, the AX Series supports both OCPP 1.6J and OCPP 2.0.1, the standard protocols used across the EV charging industry for remote monitoring, session management, and load control. Connectivity options include both wired Ethernet and wireless, providing flexibility for sites where a fixed network connection may not be available. ISO 15118 support enables automated vehicle-to-charger communication, including plug-and-charge authentication for compatible vehicles.

Fleet operators and site managers can monitor usage, configure settings, and push over-the-air firmware updates through Zerova's management platform or a compatible third-party charge management system. For sites deploying multiple AX chargers, OCPP-based load management allows the network to dynamically distribute available power across charging points, helping operators manage site electricity demand and reduce peak demand costs.

CERTIFICATIONS AND FLEET DEPLOYMENT

Both the AX48 and AX80 carry UL2594 and UL2231-1/-2 safety certifications, CTEP certification, and Energy Star certification for the North American market. Wireless certification is provided under FCC and IC, covering the built-in Wi-Fi and connectivity components. These certifications confirm that the AX Series meets the safety and performance standards required for commercial EV charging installations across Canada and the United States.

The AX Series is well-suited for fleet depot charging, workplace installations, multifamily properties, and commercial parking environments where reliable Level 2 charging is needed across multiple vehicles. The IP56/NEMA 4 enclosure, wide operating temperature range, and OCPP-based network compatibility make it a practical option for organizations building out or expanding their EV charging infrastructure. 7Gen supports fleet operators and organizations across Canada with charging infrastructure planning, site assessment, and access to government incentive programs and financing options for fleet electrification.

CHARGING SPEEDS, PROTECTION, AND LOAD MANAGEMENT IN CONTEXT

Level 2 chargers typically deliver between 3.7 kW and 22 kW, which places the AX80 at the top end of the category and makes both AX models well suited to home, workplace, and depot charging where vehicles park for several hours. For comparison, DC fast chargers deliver from 50 kW up to 350 kW and can bring many EVs to an 80% charge in 30 minutes or less depending on the charger's output and the vehicle, but they require far larger electrical infrastructure, which is why Level 2 remains the standard for most commercial settings.

The AX Series line includes built-in safety mechanisms covering under-voltage protection, over-voltage protection, surge protection, and ground fault monitoring, the protections expected of UL2231-certified charging equipment. The chargers are also equipped with local load management, allowing power output to be dynamically configured to match the site's electrical capacity. For larger deployments, hardware-agnostic energy management platforms can take this further: PowerFlex X, for example, which has onboarded the Zerova AX48 to its network, uses Adaptive Load Management to allocate power across chargers in real time based on site capacity and facility consumption, alongside other distributed energy resources such as solar and battery storage. This approach lets organizations deploy more charging ports with lower upfront electrical costs while still meeting drivers' energy needs.
