Scheme 278: DESCRIPTION
Scheme 278: DESCRIPTION
  1. The battery current sensor, which is located in the hybrid battery junction block assembly on the positive side of the HV battery, detects the amperage that flows to and from the HV battery. The battery smart unit receives a voltage of between 0 and 5 V that is in proportion to the amperage flowing in the cable. This voltage goes into the IB terminal from the battery current sensor. A battery current sensor output voltage below 2.5 V indicates that the HV battery is being charged, and a voltage above 2.5 V indicates that the HV battery is being discharged. The power management control ECU determines the amount of either charge or discharge amperage that is being received by the HV battery based on the signals that are input to terminal IB of the battery smart unit from the battery current sensor. The power management control ECU also calculates the SOC (state of charge) of the HV battery based on the accumulated amperage.
