Technically speaking, an AC charging station (also known as “Electric Vehicle Supply Equipment” or EVSE) does not charge your car battery. It provides power to the on-board AC charger in the car. This charger converts the alternating current to direct current. The direct current is used to charge the batteries.
The charging station is an 230 Volt or 400 volt outlet with some extra safety and authentication functions. Because of these safety features, standard measurement tools such as a multimeter will not work. An EV Simulator is needed to validate the correct operation of the charging station.
Before power is provided, communication through a specific communication protocol between the electric car and charging station needs to be established. This ensures safe use of electric power at all circumstances, even in the roughest (weather) environments.
Safe installation, & commissioning
The EV-Simulator simulates an electric car and is used as a tester. The EV simulator supports successful and safe installing, commissioning and periodic testing of charging stations.
When the charging station does not respond correctly, the EV-simulator gives an indication of these irregularities based on light indications (LEDs).
The EV-Simulator is typical used after installation of an EV charging station. It validates the basic functions of the newly installed EV charger. The installation crew can leave the site, knowing the charging station is fully functional, reducing the need to return to the site for inspections and repairs.
