MONITORING APPARATUS AND METHOD OF BATTERY CONTACT POINT IN CHARGE/DISCHARGE SYSTEM WITH MULTIPLE BATTERIES CONNECTED IN SERIES

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for monitoring a battery contact point in a charge/discharge system with multiple batteries connected in series.SOLUTION: A monitoring apparatus and method of a battery contact point autonomously diagnoses and measures contact resistances of a contact terminal for directly connecting a battery for charging/discharging and a circuit part in a charge/discharge apparatus for charging/discharging a single secondary battery or multiple secondary batteries connected in series.
