Electric vehicle charging technology is constantly evolving with new communication protocols, new functionalities like V2G and higher charging speeds. So, testing the charging process needs to evolve with it. With the arrival of a high power grid emulator, the Elaad Testlab is taking an important step in testing electric vehicles that charge and discharge at high power. The system can simulate a complete energy system and can therefore test the influence of heavy equipment and a heavily loaded power grid on each other. But what’s next? What does the future of electric vehicle charging testing look like? And what do you think should be tested now and in the future?
The presenters will enrich you with their in-depth knowledge. See the bottom of this page for more information about the presentations. There will also be a demonstration with Keysight, making the operation of the system concrete. Deepen your knowledge on these topics and join us on April 3!
Charging electric vehicles introduces several challenges for the electricity network in terms of capacity and in the field of power quality. Chargers for electric vehicles are large, non-linear devices with interactions that can lead to disturbances in the electricity network, one of which is supraharmonics. It is essential test the emission and immunity of devices to these disturbances, in order to ensure smooth and sustainable charging. Tim Slangen studied the disturbances caused by electric vehicle chargers in a four year research project in a collaboration between ElaadNL and Eindhoven University of Technology. In 2023 he received his PhD degree for completing his research and started working as Grid Strategist at grid operator Stedin. Here, he is responsible for developing the Power Quality strategy.
Evolution of existing charging standards, the rollout of new charging features (Plug n` Charge, Bi-Directional Power Transfer) as well as the introduction of new Charging Standards (NACS, MCS, ChaoJi) increase the complexity of global EV Charging Systems and Use Cases. To validate the performance of Charging Technology and Grid Edge related products Keysight Technology has developed a wide range of test equipment for that can be tailored to the individual testing application as well as combined to an End-to-End Testing Solution. Wolfgang Kalthoff holds a Master in “Sales Engineering and Product Management” by Ruhr-University in Bochum. Since 2018 he is working for Keysight and in his current role he is leading an international team of talented engineers which drives the global business development of Keysight`s Charging Technology and Grid Edge Test Solutions.
The recently published second edition of IEC 61851-23, together with the new release of SAE J1772, introduces new requirements for DC chargers that aim to improve performance, reliability and user experience of the next generation of DC infrastructure taking into account the evolution from LV-EV systems to HV-EV systems and increasing charger power. The new requirements come along with defined test cases to validate and certify DC-EVSE for compliance with above standards.
Beat Kreuter is the Vice President at DEKRA SE and responsible for the worldwide development of e-Mobility services that address the needs for a seamless charging experience. Beat participates in various working groups of the Open Charge Alliance and CharIN.
The thorough testing and certification of power equipment by an independent third-party is a vital step during its development and before its deployment. It significantly increases the confidence in the use of the product, indicates the level of interoperability with its intended environment and simultaneously reduces the risk of not being fit for purpose and/or violate safety conditions in the field. Apart from the ever-growing testing requirements for high-power EVSEs by themselves (functional, dielectric, EMC, protection, electrical safety, mechanical, climatic environmental, communication compliance, IP, IK, …), their impact on the electrical grid should also be validated and tested thoroughly on a system level (V2G, RfG, Power Quality, …). However, as the power of the EVSEs increase, the fidelity of testing often suffers due to power and performance level requirements exceeding existing testing infrastructure capabilities, resulting in a diminished level of confidence in the end product. In this talk KEMA will discuss the aspects pertaining to keeping high-fidelity testing as the power of EVSEs grow higher towards MegaWatt Charging Systems (MCS) and beyond, while not breaking the bank by requiring exorbitant laboratory infrastructure.
Dr. Erik de Jong is head of the Flex Power Grid Lab at KEMA labs, in Arnhem the Netherlands as well as part-time associate professor at the Eindhoven University of Technology, Electrical Energy Systems research group with focus on power-electronics dominated power grids.
The Elaad Testlabs’ goal is to speed up the transition to electric vehicles, while making sure the charging stations and vehicles are well integrated with the electricity grid. We perform free, advisory tests to help the manufacturers with these new technologies, helping them to implement smart and bidirectional charging functionalities in the right way, do not disturb the voltage of the electricity grid and are immune to voltage deviations. Because of these reasons we always want to be at the front of E-mobility developments, like bidirectional or V2X charging and Megawatt charging systems, and we want to be able to test these systems in an emulated, but near real world test setup. To be able to do this you need the right equipment, test process and knowledge. Thijs will present the changing test process at the Elaad Testlab, the upcoming test and research projects in 2024 and will introduce the new testing and measuring capabilities of the lab. Thijs is the technical lead of the Elaad Testlab, has been working in different roles at ElaadNL since 2012 and has a background in electrical engineer and innovation sciences.
