The number of charging stations in the field is increasing and with it the service effort. In order to verify that a charging station is charging properly and that nothing has been forgotten during (re)commissioning, a final functional test is mandatory after every maintenance or repair. This requirement has created many new challenges for charging station manufacturers and EVSE operator, as in the past one or two real electric vehicles, each with different charging standards, were needed to test charging stations. In addition, in the event of a malfunction, the service technicians found it difficult to identify the causes in a simple manner.
We have developed a solution for this: The comemso Mini-Charger-Tester simulates vehicle signals, communication protocols and load circuits of the charging standards DC-CCS, CHAdeMO and, if required, also AC. In this way, we have effectively put two “vehicles” in one ultra-portable, easy-to-use case. The results are displayed in real time on the touchscreen and additionally stored in the device as a report.
By using comemso Mini-Charger-Tester you ensure that your infrastructure of EVSEs is working properly and safe, does cause no defects, provides fast charging and makes sure that there is accurate billing for you as well as your customers.
HIGHLIGHTS OF MINI-CHARGER-TESTER
