Abstract

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.

Claims

1. A battery system for protecting a battery management system (BMS) from the electromagnetic waves generated by one or more battery cells of the battery system, comprising:

a battery including a plurality of battery cells;

a power relay assembly intermittently charging and discharging the battery;

the BMS connected to the battery cell via a voltage sensing wire to predict a battery'"'"'s state of charge (SOC); and

a housing surrounding the battery and the power relay assembly, the housing including a separate section configured to receive within the housing BMS,

wherein one side of the outside of the housing is configured to receive, within the separate section of the housing, the BMS to partition the BMS from the battery and the power relay,

wherein the one side of the outside of the housing configured to receive the BMS is provided with a BMS seating groove configured to receive and seat the BMS therein, the BMS seating groove formed into the one side of the outside of the housing, and

wherein once BMS is received within the BMS seating groove, the BMS does not protrude from a surface of the housing.

2. The battery system of claim 1, wherein the BMS seating groove includes one or more wire apertures through which the voltage sensing wires pass through to the battery.

3. The battery system of claim 2, wherein the wire aperture is formed on a side wall of the BMS seating groove.

4. The battery system of claim 1, wherein the BMS seating groove is formed with the wire apertures through which the voltage sensing wires pass through.

5. The battery system of claim 4, wherein the wire apertures are formed on a side wall of the BMS seating groove.
