Sonel EVSE-100 Multifunctional analyzer for electric vehicle charging stations

Description

Comprehensive charging station diagnostics with a single instrument

Multifunctional analyzer EVSE-100 is an instrument dedicated to diagnostics of electric vehicle charging stations and cables. Using a single device, we will perform a set of tests on these objects, ending with the generation of a professional report. Through appropriate simulation of CP and PP circuits, the meter can put the station into various operating states. This allows us to verify the correctness of the control system and perform measurements in the field of electric shock protection. We can complete the verification of functionality and safety by simulating errors on the power supply side, i.e. the charging station (ICCB), and charging side of the vehicle (CP circuit).

Sonel MeasureEffect™

The meter is a part of the Sonel MeasureEffect™ platform. It is a comprehensive system that enables you to take measurements, store and manage data, and provides multi-level control of your instruments.

Applications

The meter makes it possible to carry out diagnostics on:

AC electric vehicle charging stations with type 2 connector with socket or fixed charging cable (1-phase and 3-phase),
portable electric vehicle charging stations with type 2 connector (1-phase and 3-phase),
charging cables.
