Electric Vehicle Multifunctional Analyser  - Overview

This multifunctional analyser is an instrument dedicated to the diagnostics of electric vehicle charging cables and stations. Using a single device, it performs a set of tests and generates a professional report. Through appropriate simulation of CP and PP circuits, the meter can put the station into various operating states. This allows the verification of the control system and performs measurements in the field of electric shock protection. It completes 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).
