IAV expands Heimsheim facility into a development centre

IAV has announced significant investments in its home grown R&D infrastructure. The EMC test centre will be complemented with a new complex that includes work stations for 370 users and modern high-voltage testing infrastructure, test fields, and workshops. IAV will thus be taking on the high-voltage integration of future E-series vehicles at the new development site in cooperation with automotive manufacturers.


“For electromobility to take off successfully, e-vehicles need to come onto the market in sufficient variety and at shorter intervals. So development has to pick up speed, and with increasing complexity,” says Katja Ziegler, CFO of IAV.

In addition to the electromagnetic compatibility (EMC) test centre announced last year, the development centre will also include a building complex with 370 workstations for project partners and employees. In addition, there will be test areas and a complete high-voltage (HV) test infrastructure consisting of pre-integration stations, test benches for intelligent charging functions and DC fast-charge test fields. With the help of the HV infrastructure, IAV will support customers in accelerating the integration of high-voltage components into the vehicle and shortening the time to series-production readiness.

The new IAV test centre brings together all the project partners involved. They can jointly test the components in the new buildings, validate the results and further develop the components.

Construction of the development centre near the EMC testing facility began in spring 2021.

Modern high-voltage systems are far more than the interconnection of individual vehicle components. Instead, electric vehicles are characterized by the intelligent interaction of all components, systems and functions. In addition to the components that are anchored in the vehicle, charging stations, mobility providers and the customers themselves – via smartphone – are already interacting with the car.

Due to this complexity, one speaks of “distributed” functions that must harmonize with each other. This is where the work of high-voltage integration begins: It is responsible for ensuring that these distributed functions across all components meet customer expectations. At the same time, the vehicles must always be safe and intuitive for the customer to operate during operation or charging. Therefore, in addition to the classic vehicle tests, the main focus is on short-term and qualified fault analysis to improve vehicle maturity. This agile approach to high-voltage integration makes it possible to keep pace with the rapid pace of electric vehicle development.
