A HV battery current sensor, which is built into the hybrid battery junction block assembly, is used to detect the HV battery charging and discharging amperage.
The HV battery current sensor outputs voltages that change according to the current value via 2 terminals of the battery ECU assembly. The voltage that changes in proportion to the current value is output using the IB1 terminal, and the voltage that changes in inverse proportion to the current value is output using the IB0 terminal.
