Hybrid and electric vehicles adopt electric motor driven system using rechargeable battery compared to conventional vehicles. These vehicles are eco- friendly les because of no fuel consumption. These chargeable vehicles using alternative power train driven by electric motor need high efficient thermal management system in battery system in high temperature status on going charging and discharging operation . To maintain proper temperature status in battery system, BCS(Battery Cooling System) is adopted. BCS is composed of BLDC motor, inverter, sirocco type wheel and BLWR. Unit and the operating noise of BCS located under the trunk makes NVH problem in vehicle. In this paper, FEA(Finite Element Analysis) and experiment are performed for analyzing NVH characteristics of BCS , verify the noise source of BCS and propose the noise reduced design for BCS NVH problem.
