Electric Vehicle EVSE Tester

Every EV charging station belongs to the electrical installations on which the initial tests according to DIN VDE 0100-0600 (IEC 60364-6) and repeat tests according to DIN VDE 0105-0100/A1 (IEC 60364-6, Clause 6.5) and VDE 0122-1 (IEC 61851-1) must be carried out by the qualified electricians. The tests of the e-charging station include inspection, measurement and testing in accordance with the standard specifications with additional consideration of the specifications in the manufacturer's technical documentation. The performance of the tests and their results must be documented in a test report. The tests are primarily intended to determine safety against electric shock and thermal effects, against the effects of lightning and over-voltages, but also the functionality of the system. They are intended to ensure that any defects that may exist are discovered early on and can be remedied before any damage occurs.

The first test steps include the visual inspection, the test of continuity and low impedance of the protective conductor and the insulation test. After that, the active measurements are taken at the set charging voltage, including the loop impedance and, for the residual current devices, the RCD tripping time and the RCD tripping current. If a counter is present, the rotating field direction and the correct counter start-up are also checked. To ensure that the communication with the connected vehicle functions correctly, the transmitted CP signal is also checked.
