Battery Load Management
Th
e vehicle has Electric Power Management
(EPM), which 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. The voltmeter gauge or
the voltage display on the Driver Information
Center (DIC), if equipped, may show the voltage
moving 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.
A high electrical load occurs when several
of the following are on, such as: headlamps,
high beams, fog lamps, rear window defogger,
climate control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.
