Hybrid/EV Battery Current Sensor Power Supply Circuit Short to Ground or Open

DESCRIPTION

A battery current sensor is installed to the positive (+) terminal side of the HV battery and detects current flowing from the HV battery. The battery current sensor outputs voltage, which changes between 0 and 5 V according to the detected amperage, to the IB terminal of the battery voltage sensor. The battery voltage sensor sends signals to the hybrid vehicle control ECU assembly. The hybrid vehicle control ECU assembly determines the charging and discharging amount of the HV battery based on the received signals and calculates the SOC of the HV battery through the accumulated amperage.

CAUTION / NOTICE / HINT

CAUTION:

  • Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
    • Inspecting the high-voltage system
    • Disconnecting the low voltage connector of the inverter with converter assembly
    • Disconnecting the low voltage connector of the HV battery
  • To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
  • After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
  • After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
