Battery Load Management
The vehicle has 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 of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, rear window defogger, climate
control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.
