In combination with the EV-Test100 EV adapter, the MacroEVtest connects to the charging station to allow the verification of the EVSE’s complete functionality and electrical safety in compliance with standards IEC/EN 61851-1 and IEC/EN60364-7-722. EV-Test100 can test charging stations with charging modes 2 and 3 with a Type 2 or other standard connector.

The MacroEVtest controller is attached through a C100EV cable to the EV-Test100 unit, which is connected via a built-in cable with a Type2 plug to a recharging station. The handheld MacroEVtest with its touch screen display simplifies communication with the EV-Test100 unit to simulate the presence of a car being recharged. Before each test, the MacroEVtest display shows how to connect the cables and after the measurement it reports the recharging station’s safety verdict as shown by a green or red thumb symbol.

Built-in tests for charging stations include continuity test of the protection conductor, insulation test, status verification, overall ground resistance, and verification of the RCD’s tripping point for type A, B, and B 6ma. Detectable events and anomalies during the recharging phase include simulation of a fault on the protection conductor, the presence of voltages on the EVSE output connector, and verification of the mechanical lock in the charging station connection (if this function is present). The MacroEVTest can also simulate various fault conditions, including the interruption of the protective conductor (PE) or an error of the CP signal (E). It can also verify the recharging mode and the encoding of the recharge current by monitoring the PWM signal. Rated currents of charging cables can be simulated to 63 amps. All tests can be saved and the data can be transferred via WiFi or optical USB to an external PC.
