System Diagram
System Description
Power generation variable voltage control system has been adopted. By varying the voltage to the generator, engine load due to power generation of the generator is reduced and fuel consumption is decreased.
NOTE: When any malfunction is detected in the power generation variable voltage control system, power generation is performed according to the characteristic of the IC regulator in the generator.
Component Description

Description |
Battery current sensor | The battery current sensor is installed on the battery cable at the negative terminal. The battery current sensor detects the charging/ discharging current of the battery and sends a voltage signal to the ECM according to the current value detected. |
ECM | The battery current sensor detects the charging/discharging current
of the battery. The ECM judges the battery condition based on
this signal.
The ECM judges whether to request more output via the power generation voltage variable control according to the battery condition. When performing the power generation voltage variable control, the ECM calculates the target power generation voltage according to the battery condition and sends the calculated value as the power generation command value to the IPDM E/R. |
IPDM E/R | The IPDM E/R converts the received power generation command value into a pulse width modulated (PWM) command signal and sends it to the IC regulator |
Generator (IC regulator) | The IC regulator controls the power generation voltage by the target
power generation voltage based on the received PWM command
signal.
When there is no PWM command signal, the generator performs the normal power generation according to the characteristic of the IC regulator. |
