Battery Load
Management
The 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 thestate 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.
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, and loads plugged into
accessory power outlets.
EPM works to prevent
excessive discharge of the
battery. It does this by
balancing the generator's
output and the vehicle's
electrical needs. It can
increase engine idle speed to
generate more power,
whenever needed. It can
temporarily reduce the power
demands of some accessories.
Normally, these actions occur
in steps or levels, without
being noticeable. In rare cases
at the highest levels of
corrective action, this action
may be noticeable to the
driver. If so, a DIC message
might be displayed. If a battery
message is displayed, it is
recommended that the driver
reduce the electrical loads as
much as possible. See Driver
Information Center (DIC) (Base
Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132.
