BATTERY SYSTEM FOR PROTECTING BATTERY MANAGEMENT SYSTEM FROM ELECTROMAGNETIC WAVES

摘要

Disclosed is a system for protecting a BMS from electromagnetic waves, and more particularly, to a system for protecting a BMS from electromagnetic waves to prevent voltage sensing errors due to the electromagnetic waves generated by current from a battery cell. The system includes: a battery having a plurality of battery cells; a power relay assembly intermittently charging and discharging the battery; a battery management system (BMS) connected to the battery cell via a voltage sensing wire to predict a battery's SOC; and a housing surrounding the battery and the power relay assembly with one side of the outside of the housing having a separate section for therein for receiving the BMS so as to partition the BMS and the battery in different spaces.
