System Description

INFOID:0000000006161757

The generator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.

The voltage output is controlled by the IC regulator.

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

System Diagram

INFOID:0000000006161759

System Description

INFOID:0000000006161760

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.

ALMIA0057GB

Component part

Description

Battery current sensor

The battery current sensor is installed on the battery cable at the 
negative terminal. The battery current sensor detects the charg-
ing/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 cur-
rent 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 condi-
tion.
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 pow-
er 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 tar-
get power generation voltage based on the received PWM com-
mand signal.
When there is no PWM command signal, the generator performs 
the normal power generation according to the characteristic of the 
IC regulator.
