Battery systems

Designing a high-performance, long-lasting battery system requires the mastery of a wide range of multidisciplinary competencies: applied electrochemistry; electronics hardware and software; energy conversion; communication; IoT; thermal, mechanical, and vibratory engineering; manufacturing processes; as well as national and international certifications.

Therefore, complete and total control over the design through the manufacturing of lithium-ion batteries requires numerous years of expertise before all the competencies involved throughout the battery value chain can be mastered.

The reliability of the batteries we design is also based on a specific approach to battery safety. That is why we have defined an internal design process and control points that guarantee the reliability of our products over time.

All this know-how and all these fields of expertise have been endorsed by our customers – such as large electric vehicle fleet managers who benefit from our expertise in the field of swappable batteries – over the course of many years.

Faced with the growth of the battery markets, and especially with a mind toward companies that lease urban two- to four-wheel vehicles, we have opted for a #DesignForRepair approach to facilitate the repair of batteries. Our designs incorporate aspects that facilitate disassembly, allowing access to all the components and simplifying reconditioning. Our industrialized repair process includes test and diagnostic benches dedicated to these operations. Indeed, the batteries from fleets are subjected to high-stress conditions and are often mechanically damaged. In order to make it easier to repair and change them, it is necessary to engineer them with a specific design to facilitate their refurbishment. The aim of this approach is to avoid systematically recycling systems that could be repaired.

Battery safety is a major issue for all manufacturers.

Considering the spacing of the components and designing a safe mechanical architecture integrating thermal constraints and mechanical resistances are reliability guarantees that new manufacturers sometimes neglect.

Our 20 years of experience and the rigor of our 360DesignControl process allow us to also integrate high-performance electronic development, enabling us to adapt the BMS to the electrochemical components, including redundant systems. The safety of your batteries is an absolute priority for our teams.
