Smart HV-eFuse for electromobility from Rutronik’s ABU and Vishay

Posted 1 October 2021

The cooperation between the e-mobility specialists of Rutronik‘s Automotive Business Unit (ABU) and Vishay‘s Automotive Division realized a new reference design for a high-voltage (HV) circuit breaker with a maximum breaking capacity of 40 kW.

This resettable and low-loss SiC solution with MOSFETs from ROHM replaces previous options that used mechanical relays. HV switches are an indispensable link within an HV architecture of modern Battery Electric Vehicles (BEV).

They are used to safely and unambiguously separate auxiliary units from the rest of the vehicle‘s electrical architecture on the high-voltage side (400/800V side) – depending on the platform architecture – and thus prevent major damage.
