Project InMotion

The transition to electrified mobility requires battery systems that combine high performance, reliability and safety. For the development of its next-generation battery technology, InMotion partnered with VDL ETS to validate battery performance throughout the entire development process, from individual battery cells to a complete 800-volt battery pack.

Developing a high-performance battery system presents challenges on multiple levels. Battery cells must deliver the required power and charging capabilities, modules must perform efficiently under varying thermal conditions, and the complete battery pack must operate safely and reliably under realistic loads. To support these requirements, VDL ETS provided advanced testing facilities and engineering expertise, enabling comprehensive validation at every stage of development.

From cell validation to full-system testing

VDL ETS supported InMotion with a structured testing approach covering the entire battery system. Cell-level testing focused on characterising performance, fast-charging capabilities, thermal behaviour and long-term reliability. At module level, testing provided insight into thermal interactions, voltage distribution and cooling performance, helping to optimise the battery design. The final validation step involved testing the complete 800-volt battery pack under realistic operating conditions, including high-power charging and discharging scenarios and verification of cooling and safety systems.

By combining advanced test infrastructure with hands-on engineering support, VDL ETS enabled InMotion to validate critical design assumptions using real-world test data. The resulting insights into battery performance, thermal management and system reliability helped accelerate development while reducing technical risk.
