Maintenance 351 Battery management system The battery management system (BMS) monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system may temporarily disable certain electrical features to protect the battery. Those electrical accessories affected include rear defrost, heated/cooled seats, climate control fan, heated steering wheel, audio and navigation system. A message may be displayed on the instrument cluster or center stack display to alert the driver that battery protection actions are active. See the Information displays in the Instrument Cluster and Entertainment Systems chapters for more information. These messages are only for notification that an action is taking place, and do not necessarily indicate that an electrical problem exists or that the battery requires replacement. Electrical accessory installation To ensure proper operation of the BMS, any electrical devices that are added to the vehicle should not have their ground connection made directly at the negative battery post. A connection at the negative battery post can cause inaccurate measurements of the battery condition and potential incorrect system operation. Note: Electrical or electronic accessories added to the vehicle by the dealer or the owner may adversely affect battery performance and durability and may also affect the performance of other electrical systems in the vehicle. When a battery replacement is required, the battery should be replaced with a Ford recommended replacement battery that matches the electrical requirements of the vehicle. After battery replacement, or in some cases after charging the battery with an external charger, the BMS requires eight hours of vehicle sleep time (key off with doors closed) to relearn the new battery state of charge. Prior to relearning state of charge, the BMS may disable electrical features (to protect the battery) earlier than normal. 2013 Explorer (exp) Owners Guide gf, 4th Printing, November 2012 USA (fus)

Battery management system
The battery management system (BMS) monitors battery conditions and
takes actions to extend battery life. If excessive battery drain is
detected, the system may temporarily disable certain electrical features
to protect the battery. Those electrical accessories affected include rear
defrost, heated/cooled seats, climate control fan, heated steering wheel,
audio and navigation system. A message may be displayed on the
instrument cluster or center stack display to alert the driver that battery
protection actions are active. See the
Information displays
in the
Instrument Cluster
and
Entertainment Systems
chapters for more
information. These messages are only for notification that an action is
taking place, and do not necessarily indicate that an electrical problem
exists or that the battery requires replacement.
Electrical accessory installation
To ensure proper operation of the BMS, any electrical devices that are
added to the vehicle should not have their ground connection made
directly at the negative battery post. A connection at the negative
battery post can cause inaccurate measurements of the battery condition
and potential incorrect system operation.
Note:
Electrical or electronic accessories added to the vehicle by the
dealer or the owner may adversely affect battery performance and
durability and may also affect the performance of other electrical
systems in the vehicle.
When a battery replacement is required, the battery should be replaced
with a Ford recommended replacement battery that matches the
electrical requirements of the vehicle. After battery replacement, or in
some cases after charging the battery with an external charger, the BMS
requires eight hours of vehicle sleep time (key off with doors closed) to
relearn the new battery state of charge. Prior to relearning state of
charge, the BMS may disable electrical features (to protect the battery)
earlier than normal.
