Characterization of the Susceptibility to EMI of a BMS IC for Electric Vehicles by Direct Power and Bulk Current Injection

摘要

In this letter the susceptibility to Electromagnetic Interference of a Battery Management System for Lithium-Ion and Lithium Polymer battery packs employed in emerging electric and hybrid electric vehicles is addressed. For this purpose, the susceptibility to EMI of a BMS front-end integrated circuit is experimentally assessed by the direct power injection and by the Bulk Current Injection method. Experimental results are shown and discussed to highlight different EMI-induced failure mechanisms.
