DESCRIPTION

A battery current sensor, which is mounted on the positive cable side of each HV battery junction block assembly, detects the current flowing to or from the battery pack. The battery current sensor sends a voltage, which varies between 0 and 5 V in proportion to the amperage, to the IB0 terminal of the battery ECU assembly. Similarly, it sends a voltage, which varies between 0 and 5 V in inverse proportion to the amperage, to the IB1 terminal of the battery ECU assembly. When the voltage at the IB0 terminal is below 2.92 V and the voltage at the IB1 terminal is above 2.08 V, this indicates that the HV battery is being discharged. Additionally, Meanwhile, when the voltage at of the IB0 terminal is above 2.92 V and the voltage at of the IB1 terminal is below 2.08 V, this indicates that the HV battery is being charged. The battery ECU assembly determines the charging and discharging amount of the HV battery based on the voltages input to the IB0 terminal and IB1 terminal and calculates the SOC of the HV battery through the accumulated amperage.
