Description
1
IPDM E/R
The IPDM E/R converts the received power generation com-
mand value into a pulse width modulated (PWM) command sig-
nal and sends it to the IC regulator.
2
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 con-
trol, the ECM calculates the target power generation voltage
according to the battery condition and sends the calculated val-
ue as the power generation command value to the IPDM E/R.
3
Battery current sensor
The battery current sensor is located on the negative battery
cable terminal. The battery current sensor detects the charg-
ing/discharging current of the battery and sends a voltage sig-
nal to the ECM according to the current value detected.
4
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 per-
forms the normal power generation according to the character-
istic of the IC regulator.
5
Combination meter (charge warning lamp)
The IC regulator warning function activates to illuminate the
charge warning lamp if any of the following symptoms occur
while generator is operating:
·Excessive voltage is produced.
·No voltage is produced.

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
System Diagram
INFOID:0000000009682021
System Description
INFOID:0000000009682022
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.
