Eaton – Battery disconnect unit

Featuring Breaktor™ circuit protection, the battery disconnect unit (BDU) is designed to efficiently distribute power throughout the electric vehicle (EV) system. The BDU provides improved quality and simplified architecture by combining current switching and resettable bidirectional short-circuit protection with fast actuation (up to 900V).

Enabling reduction of up to 15 components from the PDU assembly, Breaktor’s™ integrated coil driver, economizer, and sensing/triggering circuit reduce overall cost and complexity. Additionally, it’s self-triggering design, diagnostic electronics, and mirror contact help to ensure utmost safety and reliability.
