CREATING UNIQUE DIGITAL EXPERIENCES

Since 2020

Protects Your Electric Vehicle
Test a charger that is not working or suspected faulty without using your car. Built-in fuses provide protection.
Protection and Earth Testing
Built-in fuses provide protection, and the measurement terminals allow the charger to be checked for short circuits.
Simulates the Vehicle's Communication Unit
Lets you manually emulate your car's communication unit, so it can be used in cable disconnected, cable connected and charging modes.

Electric Vehicle Test Equipment Solutions

This test box lets you step manually and thoroughly through the states used by an SAE J1772 charging station (EVSE). It includes a function to verify operation of the Proximity Pilot (PP) switch controlled by the connector latch, and it can also simulate an earth (ground) fault.

Electric Vehicle Charger Tester

This easy-to-use EV charger tester works without any additional power source. It is simple to operate and can simulate the vehicle’s communication unit, so you can directly check whether the charger detects the charging cable and starts the charging process. Built-in fuses make it safe, protecting against overload and short circuits, and the easily replaceable fuse makes it practical and convenient.

1 – No additional power source required

Connects directly to the EV charger. Supports single-phase and three-phase chargers.

2 – Easy to use

Plug-and-play operation – no separate power connection needed.

3 – Manual triggering

A rotary selector switch lets you manually perform the vehicle's communication functions, simulating cable connection and the start of charging.

4 – Safe

The built-in fuse protects against overload and incorrect connection.

5 – Saves time

Laboratory-type banana connectors make measurements and earth testing easy, allowing fast use alongside other test instruments.

Portable EV Charger Test Unit

This EVSE test unit is fully portable and lets you test your charger without an electric vehicle. You can identify cable faults, signal faults and earth faults within seconds. A selector switch lets you reproduce vehicle states such as ‘vehicle connected’ and ‘charging started’, just like a real car.

Compatible with Type 1 and Type 2 Charging Connectors

Compatible with Type 1 (SAE J1772) and Type 2 (IEC 62196-2) charging connectors, so you can test both single-phase and three-phase chargers without an adapter – saving time during testing.

How to Use

Once the plug is connected, the selector switch functions are as follows:

State A – Cable Disconnected

You can check the earth connection. If you see any voltage at the banana connectors, there is a wiring fault and the charger should not be used with your car. You can see standard device tests in the video.

State B – Cable Connected

The CP voltage varies depending on the device, and you can see the corresponding indicator on your EVSE. If you measure any voltage at the banana connectors, there is a problem, and you should check your EVSE connections.

State C – Charging Started

This step triggers the EVSE and you will see voltage at the banana connectors. If no phase voltage appears, there is a problem with your EVSE.

The tester also has a fuse on each phase, protecting your equipment from unexpected problems when you use it as a load simulator.
