The susceptibility to Electromagnetic Interference (EMI) of Battery Management Systems (BMSs) for Li-ion and LiPo battery packs employed in emerging electric and hybrid electric vehicles is investigated in this paper. To this purpose, a specif c test board is developed to experimentally assess the EMI susceptibility of a BMS front-end integrated circuit by direct power injection (DPI) and radiated susceptibility measurements. Experimental results are discussed highlighting different EMI-induced failure mechanisms observed during the tests.
