Easy Chester

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.
