InMotion is taking a revolutionary step in the energy transition with 'Electric Refueling', where the battery of their LMP3 race car charges within four minutes. Our engineers supported this TU Eindhoven student team by actually mapping the specific safety risks of this unique design.
When developing the 'Revolution' LMP3 race car, InMotion encountered a critical challenge. Because their battery pack is the only one of its kind, standard risk assessments did not suffice. Invisible hazards such as an electric arc - an electrical discharge with extreme heat generation - posed a real threat to team members working on the installation.
Without exact data on the energy impact during a short circuit, it was impossible to select the right Personal Protective Equipment (PPE). This uncertainty about the cause and impact of electrical risks required an in-depth technical diagnosis to ensure a safe working environment and avoid production stoppages during testing.

Our engineers performed specialist arc calculations on the entire battery pack. By modelling the installation and simulating various scenarios, we mapped out the exact current and heat development in the event of a discharge. This methodology provided the team with the factual underpinning needed when working on complex high-voltage components.
During this analysis, we also assessed whether the distribution boxes complied with the DGUV 203-077 standard. By translating technical findings directly into practice, we made the complex subject matter accessible to the team. This proactive approach ensured that every risk was identified before the car took to the track.
InMotion translated our advice directly into practice, which means that safety around the battery pack is now conclusively established. By determining the exact PPE level per junction box and limiting the impact of electric arcs, we minimised the risks. As a result, the team now has the right equipment and specific safety procedures that seamlessly address the risks of their innovative battery design.
The cooperation results in a stable installation where safety is guaranteed. With the applied labels and the validated final report, InMotion has the assurance that they are working in accordance with the highest standards. This lays the foundation for their next goal: proving the technology at the prestigious 24 Hours of Le Mans.
