Optimal handling of SiC electronics
The company’s laminated bus bars offer a compact, low-inductance power distribution solution for EV drivetrains, battery modules, inverters, and charging systems. These custom interconnections reduce parasitic inductance and assembly complexity, improve thermal behavior, and boost reliability. Their multilayer design supports optimized routing, mechanical stability, and EMC in compact systems.
Designed for SiC power electronics, the bus bars use advanced insulation materials like polyimide and polyaramide, ensuring resilience up to 180°C – far above standard 105°C – enabling reliable operation under extreme thermal loads in high-efficiency EV systems.
Reliable protection for battery modules
Mersen’s EVpack-fuses and M-fuses meet the load demands of electric and hybrid vehicles. They interrupt high DC fault currents with low let-through energy, protecting systems and passengers. Compliant with ISO 8820 and UL 248, they cover 100–1,000 VDC and up to 800 A. With breaking capacity under 2 kA, they match DC switchgear specs, ideal for battery packs and distribution units. Compact design and low I²t values support space-saving, high-performance protection.
High-performance thermal management
Vacuum-brazed, liquid-cooled cold plates made by the company ensure efficient thermal management for power modules in EVs, chargers, and inverters. Designed for high heat flux and seam-free watertightness, they offer advancements in thermal conductivity and uniformity. The ECS LV100 MAXX platform lowers pressure loss and supports stable switching in silicon and SiC modules like LV100, XHPTM, and LV NHPD2. Custom-fit to module footprints, these cold plates meet strict thermal limits while enabling compact, high-density designs.
The optimum battery assembly solution
The Infinicell solution made by the company offers OEMs a scalable platform for EV battery cell connections that is reliable, standardized, and provides faster production throughput. Each module integrates prismatic cells, laminated bus bars, liquid cooling, and EVpack fuses into a plug-and-play unit for high-voltage systems. A laser bonder interface enables robust, high-speed cell-to-bus-bar-bonding, over four times faster than wire or ribbon bonding. Further characteristics include built-in safety features and a cost-optimized design.
With deep expertise in power electronics, thermal management, and protection, Mersen aims to drive the next generation of electric mobility. Its compact, reliable, high-performance solutions help OEMs and infrastructure providers build a cleaner, electrified future.
