Recently at the The Battery Show Europe 2026, Sensata’s Electrification Product Group Owner for Automotive and Commercial Equipment Mark McBrine, shared an engineering-focused perspective on a growing challenge in EV systems: high voltage fault management in next generation architectures. Highlights from the session covered: • Traditional protection architectures are reaching their limits as rising battery voltage and power demands push contactor and fuse-based systems beyond their original design envelope. • Fault behavior and energy levels vary widely across EV systems, creating risk scenarios where existing technologies introduce trade-offs between safety, uptime, and system cost. • New approaches like Sensata’s FaultBreak ™ enable ultra-fast, passive, and resettable fault protection, combining contactor switching and fuse-level protection while simplifying system design.
