Ensuring correct EV and EVSE communication
Charging test systems for charging communication according to DIN 70121 and ISO 15118
Eclipseina offers up-to-date test solutions based on the DIN 70121 and ISO 15118 charging standards for both the vehicle and the charging station. Hardware in the Loop HIL as well as Software in the Loop SIL solutions are offered.
Why do I need a charging test system?
Interoperability testing for EV and EVSE
Do you want to ensure that your electric vehicle can be charged at any charging station or that your charging station can be used by all common vehicles on the market? With interoperability testing, you can ensure that your solution meets the requirements.
Quality assurance during development
Early testing ensures a successful product development. Charging test system can be used during the development phase and thus ensuring quality already at this point. At an earlier stage of development SIL tests are performed and later the test with the hardware is added.
End-of-line testing in electronics production
A targeted test selection for end-of-line testing in your electronics production ensures that the charging communication of the individual charging controllers and control units works properly.
EC-CHARGE-TEST is a test solution for charging points with respect to DIN 70121 and ISO 15118 compliant signal transmission.
The hardware board is connected to the system under test via the connections CP, PE and PP, which are standardized for charging communication. The system under test SUT is either a charging point or an electric vehicle. A BNC connector for CP against PE as well as banana jacks for CP, PE and PP are available as standard connections.
The hardware is supplemented by the corresponding firmware on the hardware board and a PC environment.
The simulation software EC-SIM-EV or EC-SIM-EVSE, supplemented by corresponding test cases, ensures the communication according to DIN 70121 and ISO 15118 and is executing the test cases.
With EC-SIM-EV/SE Eclipseina offers a comprehensive software solution for the hardware EC-CHARGE-TEST. This software for charge point EVSE or electric vehicle EV simulation provides the environment for the integration of DIN 70121 and ISO 15118 compliant signal transmission tests.
The simulation software EC-SIM-EV or EC-SIM-EVSE is composed of the user interface and is completed by the HIL test packages. Together with the test hardware EC-CHARGE-TEST, this solution enables stand-alone testing of the charging communication that takes place between the electric vehicle and the charging station. The test cases of both DIN 70122 and ISO 15118-4/-5 are available.
- PLC communication via control pilot (CP) and protective earth (PE).
- PLC and PWM generation
- For AC and DC charging communication
- Standard compliant simulation software
The test packages cover all test cases from the test standards DIN 70122 and ISO 15118-4/-5:
EC-TESTS-EV contains the test cases for testing the charging communication with the EV electric vehicle
EC-TESTS-EVSE contains the test cases for the test of the communication with the charging station EVSE
In order to meet customer-specific needs, the test packages have been divided into the various sub-aspects and can be selected for electric vehicles EV and for charging stations EVSE based on the following criteria:
- Test according to DIN 70122 resp. ISO 15118-4/-5
- AC charging / DC charging
- SLAC communication / high-level communication via V2G
Customer-specific test cases that go beyond the standard are covered by our expert and test support.
The SIL software provides the environment for the integration of the DIN 70121 and ISO 15118 compliant signal transmission tests. The simulation software EC-SIL-EV or EC-SIL-EVSE consists of the user interface and is complemented by the SIL test packages.
This software in the loop test environment enables a test of the software solution at an early stage of development, e.g. when no hardware is available yet.
The own development software can thus be tested against a simulation environment. For this purpose, an interface description of the individual software functions is provided.
The test packages are integrated into the SIL software environment and cover the V2G test cases from the test standards DIN 70122 and ISO 15118-4/-5.
In order to meet customer-specific requirements, the test packages have been divided into the various sub-aspects and can be selected for electric vehicles EV and for charging stations EVSE on the basis of the following criteria:
- Test according to DIN 70122 resp. ISO 15118-4/-5
- AC charging AC / DC charging DC
Since the SIL tests are performed exclusively on the PC, there is no low-level communication via PWM and also no physical powerline communication. For this reason, in contrast to the HIL test solution, only V2G test cases are available, but not SLAC test cases.
Further customer-specific test cases that go beyond the contents specified in the standard are covered by our expert and test support.

Demonstration of testing the charging communication between EV and EVSE
In most cases, developers lack the counterpart, i.e. either access to the electric vehicle or the charging pole, to fully test their own development samples. During testing, just testing the good case is not enough. You also want to check the reaction in the limit range and the correct behavior in the event of a fault and thus a test environment is needed.
In this video, we show you how such a test can be carried out successfully.
