(P12-15) Upgrade Your Battery Disconnect Switch to Semiconductor Solutions - Compact, Fast, and Safe

This presentation explores the transition from mechanical battery disconnect systems to semiconductor-based battery disconnect units (BDUs) and eFuses in electrified vehicles. Driven by higher charging power, rising battery voltages, and bidirectional energy flows, these solutions offer microsecond-scale fault response, resettable protection, and potential space and weight reductions exceeding 60%. It highlights how Infineon’s semiconductor portfolio, packaging capabilities, and functional safety expertise support this transition, emphasizing system integration as key to realizing these benefits.
