KIA Niro: Battery Current Sensor

Specification

Battery Current Sensor

Specification

Description

Battery Current Sensor is integrated into the Power Relay Assembly (PRA) and measures the current
of the high voltage battery during charging or discharging.

Installation

Warning

• Be sure to read and follow the "General Safety Information and Caution" before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
• Be sure to read and follow the "High Voltage Shut-off Procedures" before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.

1. Install in the reverse order of removal.

1. Connect the KDS to the Data Link Connector (DLC).
2. Turn the ignition switch ON.
3. Check the battery current in KDS service data.

Main Fuse

Specification

Description

The main fuse is mounted in the safety plug and protects the high voltage battery and high voltage circuits from overcurrent.
