CONTACTOR ISOLATION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To isolate electrical energy storage components.SOLUTION: A contactor unit includes: an input lead connectable to a first lead of an energy output device; an output lead connectable to a first lead of a voltage bus; a contactor for connection and disconnection between the input lead and the output lead; a driver configured to operate the contactor; a serial data link connectable to a system controller that is external to the contactor unit; and an integrated circuit (IC) positioned within the contactor unit and configured to output to the driver a control command for opening the contactor on the basis of at least one of a current in either the input lead or the output lead and a voltage differential across the contactor, and output a contactor control status via the serial data link.
