Comemso Easy Chester

Generation FLEX for CCS, NACS & CHAdeMO with the Variants mobile, EOL & Eichrecht

The new champion in electromobility

The new Easy Chester, previously called “Mini-Charger-Tester”, is designed for mobile use in the field, for service and maintenance. This easy charger
tester completely redesigned generation, which includes Flex technology, is operated intuitively via a touchscreen and also provides comprehensive reports.

The easy-to-use charging station tester

The number of charging stations in the field is increasing, and so is the cost of maintaining them. To ensure that a charging station works as expected, a final functionality test is essential after installation, a service interval or repairs have been carried out. The testers often use two different vehicles to test the charging stations, e.g. one with a CCS connection and the other with CHAdeMO.

To simplify these tests and obtain reliable and reproducible results, comemso offers the portable Easy Chester. The tester can simulate vehicle signals, communication protocols and the output of a small vehicle battery for the charging standards DC-CCS, NACS and CHAdeMO, as well as AC on request (but without load circuit).

The test results are displayed in real time on the touchscreen and can be saved in the device. The Easy Chester can therefore simulate two vehicles with different charging standards, all in an ultra-portable, very easy-to-use device with meaningful test reports. It also provides a standardized vehicle behaviour, as opposed to the individual behaviours of various vehicle brands.

Testing of electrical systems

Testing electrical systems is a very important and preventative tool for increasing reliability and service life.

The standards of the last few decades have enormously increased the requirements for electrical installations. As a result, the importance of testing electrical devices for the field of electrical installation technology has developed into a very important line of work in its own right in the area of electrical installation technology. The following three standards are highly relevant for testing in the field, this means also on site at the respective charging station.

Standards

• Initial tests – DIN VDE 0100-600
  The initial tests are carried out to determine whether the protection of people and property is guaranteed. The test is intended to detect defects that may have been caused during the installation or operation of electrical systems.
• Periodic testing – DIN VDE 0105-100
  Periodic inspections at fixed intervals intended to determine the condition of electrical installations.
•  Testing after repair or modification – DIN VDE 0701-0702
  Testing the electrical safety of electrical devices after repair work and modifications, for example, is regulated by the DIN VDE 0701-0702 standard „Testing after repair, modifications“. There are time specifications for the inspections - for charging stations these are inspections due after one year.

The initial and periodic inspection is not just a matter of safety. Early defects and sources of danger can be detected and resolved thanks to thorough testing procedures.

The advantage of this process is the early detection of initial damage, ageing processes and thus also preventive measures for major repairs.

Testing charging stations the easy way

Operating the Easy Chester is as simple as can be

• Connect the charging cable and press Start to initiate the test
• Track the results on the display

A large memory to save all data even after maintenance

• The Easy Chester offers plenty of memory capacity to store all data
• Evaluate the protocols later from your computer or print them out whenever you like

Power supply made easy

When the charging station has a service panel with an integrated socket, the Easy Chester can be easily operated via this socket (85 - 245 V AC).
With a 1 kW sine wave inverter that can be connected to a 12 V cigarette lighter, the Easy Chester is also easy to operate from a car.

1.  The Easy Chester simulates two different electric vehicles
   With the Easy Chester, you don‘t need a vehicle for testing, as the device can simulate up to two different vehicles.
2. Comprehensive EV simulation
   Fully automatic EV simulation regarding communication and the DC load circuit.
3. Results in real time
   Test results are displayed in real time on the touchscreen and are also saved in the device.
4. Portability
   The Easy Chester is equipped with transport wheels and handles, making it ideal for mobile use.
5. No computer required on site
   No computer is required for on-site testing thanks to the built-in touch display.
6. Recognizing the limits of the charging station
   What is the true charging capacity? The charging station communicates the possible charging capacity to the Easy Chester, from where it is documented and can also be viewed in the test report.
7. Advantages of simulated test vehicles
   By simulating vehicles, it is possible to provide comprehensive test results for service technicians. With a vehicle, this would be quite a challenge.
8. Supports various recurring safety tests
   Leakage current, CP short circuit, PE line break, insulation monitor test, CP communication signal short circuit.
9.  Test report featuring your own company logo
   You have the option of generating your test reports with your own company logo, giving them a personal touch.
