2016 Edge Sport Battery Monitoring System?

Recommended Posts

Hi All,

 

Just replaced the OEM battery BXT-90T5-590 with the larger BAGM-48H6-760.  I did not see a battery management system module (BMS) which I believe is usually attached to the negative battery cable.  Also, I did try to reset the BMS by doing the high beam flash 5-7X, apply brakes 3X all within 10 secs but nothing happened.  So, anyone know how to tell if I have a BMS or post a pic?  If I do, do I need Forscan or dealer to reset?  TIA

Yup, that’s my default solution if there are no other options. Thanks very much!

On the 2015+ if a new battery is installed, it has to be reset using a scan tool. The below is from the 2015 Service Manual:

Battery Replacement

If the vehicle battery is replaced, it is very important to perform the BMS Reset using a diagnostic scan tool. If the battery monitoring system reset is not carried out, it holds the old battery parameters and time in service counter in memory. Additionally it tells the system the battery is in an aged state and may limit the Electrical Energy Management system functions For more information, Refer to: Battery and Cables ­ System Operation and Component Description (414­01 Battery, Mounting and Cables, Description and Operation).

Battery Charging or Jump Starting
To charge or jump start the vehicle, connect the positive cable to the battery positive post. It is preferred to connect the
negative cable to a vehicle ground and not the battery negative post. Connecting directly to the negative battery post can
have an adverse effect on the Electrical Energy Management system. For a good connection point, follow the cable from
the battery negative post to the vehicle body connection (typically on the shock tower sheet metal) and connect there.
If the battery is jump started or charged, the BCM must recalibrate the battery state of charge. Engine off load shedding
may occur if the vehicle is operated before the BCM calibrates the new battery state of charge.
NOTICE: DO NOT reset the battery monitoring system using the diagnostic scan tool. This reset is reserved for
new battery installation. Resetting the battery monitoring system will clear the learned battery data, the battery
time in service, and will affect the aging algorithm parameters, which have been learned since the installation of
the battery.

 

some of the caveats noted


Battery State of Charge
The BCM uses the battery current sensor to keep track of the battery state of charge. During a drive cycle the Electrical
Energy Management software adjusts the battery state of charge up during charging, and down during discharge.

 

During rest periods with the key off, and the vehicle enters sleep mode, the BCM automatically recalibrates the Battery
State of Charge. It takes 8 hours in sleep mode, with the vehicle undisturbed, no doors opened or keyless entry buttons
pressed, and the total vehicle current draw less than 300mA, to calibrate the battery state of charge to a high accuracy. If
the system draw has not allowed the battery state of charge to calibrate over the previous 7 days, the state of charge
quality factor changes to identify this and some Electrical Energy Management system functions may be temporarily
turned off until a calibration takes place.

Is the BMS optional or standard equipment on 2015+?  What does it look like and where is it located?

Battery monitoring is standard on all Fords for quite some time now, so yes all 2015+ Edges. It's part of the BCM, not a separate module.
