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.
