SIMPLIFY YOUR EVSE TESTS / CHARGER TESTS
AT EVSE MAINTENANCE AND SERVICE IN THE FIELD OR AT EVSE END-OF-LINE TEST

Easy to use charging station test, with logged reports and automatable if required. Always best-in-class, since many years.

For DC-CCS, CHAdeMO, AC and even GB/T (DC-China).

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 stations 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 and 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 combined 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. Besides the systems for development we also offer the combined Mini-Charger-Tester for service application, maintenance as well as End-of-Line-testing. New in Generation 3.3: Now with intuitive touch screen, informative reports and even easier operation.

HIGHLIGHTS OF MINI-CHARGER-TESTER

Simulation of conductive electric vehicles according to CCS (DIN 70121, ISO 15118) and CHAdeMO 1.2 or lower (2.0 coming soon); optional AC or GB/T DC-China
Fully automatic EV-Simulation on communication and load circuit
No computer required for on-site testing
Safety test of EVSE (DC-CCS only) to check isolation fault recognition
Special Fault Injection on DC-CCS signal lines (PE cut, CP short)

AN INNOVATION THAT INSPIRES

The award had been created to reward ingenuity, pioneering spirit and the courage to perform unusual feats. comemso is one of the winners of the 2019 Innovation Prize of the district of Esslingen (Baden-Wuerttemberg) with the Mini-Charger-Tester.

SUITCASE

COMBINED
MINI-CHARGER-TESTER
FOR FIELD

If you search for a device that is made for transportability and use on-site, the combined Mini-Charger-Tester is the natural choice. The device simulates vehicle signals of the charging standards DC-CCS and/or CHAdeMO or DC-China, so it represents virtually up to two vehicles in an ultraportable suitcase. This small power package is perfectly suited for maintenance, testing after commissioning / installation and shows you the test results (passed/failed) clearly on its touch display. Furthermore there are features like failure injection, set charging time, etc. The device is generally operated via the touch display. With the associated PC software, all test results can be transferred to your PC as a PDF.

Up to two “vehicles” in an ultra-portable, easy-to-use case
Test results are displayed in real time on the touchscreen and additionally stored in the device
Integrated emulated vehicle load circuit with 300V battery voltage and 6A charging current (fixed setting)
Made for field use: the Mini-Charger-Tester can be powered by an 1 kW sine wave inverter (optional, not included) connected to the 12V cigarette lighter.
See the video at the bottom of the page for a practical example.

TABLETOP

COMBINED
MINI-CHARGER-TESTER EOL
FOR END-OF-LINE-TEST

In case your focus is on End-Of-Line (EOL) testing in production you should opt for this tabletop version: it‘s designed to be operated with an End-of-Line test bench to find out if the EVSE is working as expected. Of course the tabletop can as well be used in field just like the suitcase version, yet with the Mini EoL you combine most advantages of the suitcase with additional features like continuous EoL-testing for up to 8 hours per day under laboratory conditions, adjustable charging time from a few seconds to max. 60 minutes as well as automated charging tests.

Designed to be operated with an End-of-Line test bench
Made for continuous operation (up to 8 hours) under laboratory conditions
Integrated emulated vehicle load circuit with 300V battery voltage and 7A charging current (fixed setting), optimal cooling for continuous operation
Tabletop version, yet still a viable option for field use as well
Adjustable charging time from a few seconds to max. 60 minutes
Automated charging tests, remotely controllable via SCPI commands (UART/RS232 interface)

COMBINED
MINI-CHARGER-TESTER EOL HPC
FOR END-OF-LINE-TEST
WITH HIGH-POWER-CHARGING

Your demands are even higher? If your focus is on End-Of-Line (EOL) testing with high power charging, the Mini-Charger-Tester EOL HPC can still be installed in a single, rollable rack for loads of up to 120 kW. If you need even a higher DC battery emulation for testing the maximum performance of your EVSE you can extend your system using battery emulators to reach DC-loads of up to 500kW 1000V/500A. Please talk with our sales team to select the fitting battery emulation / bi-directional power supply. Like the tabletop version, this rack version is also designed for continuous operation of up to 8 hours per day under laboratory conditions.

Designed to be operated with an End-of-Line test bench
Supports high power charging, up to 120 kW in one 38 HU Rack, emulated EV load circuit adjustable in the range of 250V – 350V battery voltage and 5A – 250A charging current
By using separate battery emulators you can even reach DC-loads of up to 500kW (1000V/500A). But no 500kW mains power is necessary, since the power is regeneratively shifted in a circle – see the block diagram below for an explanation.
Designed for continuous operation (up to 8 hours) under laboratory conditions
Adjustable charging time from a few seconds to infinite
Automated charging tests, remotely controllable via SCPI commands (UART/RS232 interface)
