Degradation of Electrical Contactors

contactor schematic

Electrical Contactors are a high voltage and current relay, designed to allow a battery pack to be electrically isolated from the system. Hence in the open state they need to electrically isolate and in the closed state they need to provide a robust low resistance electrical path. Degradation will primarily be an increase in contact … Read more

Tab Materials and Current Flow in Li-Ion Cells

battery cell tab cross-sectional area versus peak current capability

AION Engineering INC Role of Tabs in Current Flow During discharge, the current generated by electrochemical reactions flows through the sequence: Active Material → Conductive Additive → Current Collector → Tab The tab serves as the final current-carrying element in this path. Its current-carrying capacity is therefore a critical factor that affects both electrical efficiency … Read more
