Charging technology without EMC interference
Mooser can test all your charging systems, including onboard chargers, wallboxes and outdoor chargepoints.
If you say “E” for electromobility, you also have to say “C” for charging infrastructure: without functioning onboard chargers, wallboxes, chargepoints and the like, e- vehicles literally lack the juice. To ensure that this does not happen, Mooser tests these components with the usual thoroughness for their electromagnetic compatibility.
Charging systems: new measurement chambers, proven measurement methods
We test your charging infrastructure for EMC
Do you need EMC measurements of A- or B-samples of onboard chargers during development? Do you want to eliminate interference from your products or subject them to a type approval process? Would you like to test your wallboxes and chargepoints for EMC? Our specialists can resolve your problems. In future, they will also carry out acceptance tests.
Chargepoints for electric vehicles make up part of the critical infrastructure for the mobility transition. . For this reason, the development processes are demanding and the safety and reliability requirements for onboard and stationary chargers are correspondingly high. None of the market players can afford to have problems with electromagnetic interference.
New measurement chambers for chargepoints and wallboxes from 2023
We have been working with electric vehicles for years. We have been working with electric vehicles for years. We offer a broad spectrum of EMC tests on electric traction motors, batteries, inverters and other high-voltage components and we can help you to resolve a variety of different types of problems. Now we have added services for optimising the EMC of the charging infrastructure to our portfolio.
We have already successfully completed our first projects involving onboard chargers in the early stages of development. These included measures and acceptance tests as part of the type approval process. In future, we will also be able to test wallboxes and public chargepoints.
Testing the charging infrastructure using proven measurement methods
During EMC tests of the charging infrastructure, we make use of all our existing measurement expertise and apply the same high standards of precision. The components and systems installed in the vehicles are tested in accordance with the same automotive standards as other high-voltage automotive parts. These include the UN regulation ECE R10, ISO 11452-X, CISPR 25, ISO/TS 7637-4, LV 123, LV 124 and VDA 320, together with manufacturers’ specifications, plus IEC 61980-X and CLC IEC/TS 61980-X (wireless power transfer). We focus both on interference emissions and on immunity to interference from external sources. As we work with these standards and procedures on a day-to-day basis, you can expect the same standards of care and precision in our EMC tests of charging infrastructure. That is our promise to you!
The EMC of wallboxes and chargepoints is also regulated by CE standards for industrial and domestic products. In some cases, these standards require lower field strengths and different test parameters because the interference from the power grid can differ from that caused by a vehicle electrical system, for example. The stationary charging devices connected to the public electricity grid are also tested in accordance with IEC/EN 61000-6-X.
You can benefit from our experience and customer focus
Development testing, eliminating interference, type approval: we offer the same comprehensive portfolio of services for onboard chargers as we do for other high-voltage components. You can benefit from our knowledge in areas such as interference emissions, couplings, immunity to interference and elimination of interference, which we have built up over more than four decades. We will be happy to share our expertise on all aspects of EMC as part of a joint project with the aim of improving your charging devices and chargepoints.
You can also benefit from EMC measurements in our laboratories, because we can assess your charging infrastructure components before the actual test process, identify the ideal test layout to meet your requirements, run tests independently and then discuss the results with you in detail. After this, we will be happy to help you with eliminating any interference in your components. More accurately, a highly qualified Mooser employee will support you and act as your point of contact for the entire project. He will respond to your enquiries and requirements, running the tests and answering any questions you may have..
Frequently asked Questions
Onboard chargers are permanently installed in the vehicle and can therefore have a direct impact on the vehicle’s electronics if they are not EMC-compliant. Although wallboxes and chargepoints are stationary devices, they are connected with the vehicle during the charging process and can therefore introduce electromagnetic interference into the vehicle’s electronic and electrical systems As the charging voltages are generally high, the risk of electromagnetic interference is greater than in low-voltage systems.
The components and systems installed in vehicles are covered by the same automotive EMC standards as other high-voltage automotive parts. These include the UN regulation ECE R10, ISO 11452-X, CISPR 25, ISO/TS 7637-4, LV 123, LV 124 and VDA 320, together with manufacturers’ specifications, plus IEC 61980-X and CLC IEC/TS 61980-X (wireless power transfer). The stationary charging devices connected to the public electricity grid are tested in accordance with IEC/EN 61000-6-X. For this reason, interference emissions are just as important as immunity to external influences.
Wallboxes and chargepoints must also comply with CE standards for industrial and domestic products. In some cases, these standards require thresholds and test parameters in the EMC tests that differ from those of automotive standards. However, the same measurement systems and processes can be used for both CE and automotive standards.
