Battery Load
Management
The vehicle may have Electric
Power Management (EPM) that
estimates the battery's temperature
and state of charge. It then adjusts
the voltage for best performance
and extended life of the battery. When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging.
If the vehicle has a voltmeter gauge
or a voltage display on the Driver
Information Center (DIC), you may
see the voltage move up or down.
This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
