Battery Current Sensor

COMPONENT PARTS

Battery Current Sensor

The power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the power generation of the generator.
Based on sensor signals, ECM judges whether or not the power generation voltage variable control is performed. When performing the power generation voltage variable control, ECM calculates the target power generation voltage based on the sensor signal. And ECM sends the calculated value as the power generation command value to IPDM E/R.

CAUTION:
Never connect the electrical component or the ground wire directly to the 12V battery terminal. The connection causes the malfunction of the power generation voltage variable control, and then the 12V
battery discharge may occur.
The battery current sensor is installed to the 12V battery negative cable. The sensor measures the charging/
discharging current of the 12V battery.
