How does the PCM adjust the charging voltage?

How does the PCM adjust the charging voltage?

The PCM is able to adjust the charging voltage according to battery temperature by using a signal from the intake air temperature (IAT) sensor. This means that the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.

How does the Battery Control Module ( BCM ) work?

It monitors a battery current sensor, the battery positive voltage circuit, and estimated battery temperature to determine battery state-of-charge (SOC). The BCM performs idle boost and load management operations.

How is the generator controlled by the PCM?

When Generator operation is desired, the PCM sends a 5 volt signal to the voltage regulator via the generator turn on signal circuit. This causes the voltage regulator to begin controlling the generator field circuit. Once the Generator is enabled by the PCM, the voltage regulator controls generator output independently of the PCM.

How to bypass the Generator Battery Control Module?

How to bypass the Generator Battery Control Module on 2006 Chevy truck so that I can get alternator to put out 14 volt all the time. My battery light came on while i was driving than a few minutes later everything shut off. The battery was replaced in january and alternator was replaced in october.. what could be the problem?

How does the PCM control the charging system?

The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running).

It monitors a battery current sensor, the battery positive voltage circuit, and estimated battery temperature to determine battery state-of-charge (SOC). The BCM performs idle boost and load management operations.

Is there such a thing as a smart charging system?

No matter how complex ‘smart’ charging systems appear at first glance, it still comes down to a battery, an alternator and some modules monitoring and controlling voltage regulation. We’re sure you’ve got the smarts to handle that.
