Re: First Major Repair on Battery

Thanks Bolt - I wasn't sure what the supply chain looked like. I'm on day 6.

Re: First Major Repair on Battery

I'm really relieved to hear that the removal/replacement process was fairly easy; the videos from the factory had me concerned. Would you mind providing an idea of the time elapsed between when Ford decided the battery pack could not be repaired and the replacement battery arrived at your dealership...

Re: Number of battery cells finally discovered....

Hmmm, not nitpicking but I would have bet on 86 cells. I have a transcript from the assistance hotline specifying a cell voltage of 4.07 V and confirming OBD data.

Re: Reported range drop normal?

1) Short answer: This is more or less normal. The 86 mile estimate was based on much more conservative driving than your test drive represented. Jamie has an excellent blog here: http://jamiegeek.myevblog.com/ ... in particular you should read up on the Guess-O-meter. 2) There have been a couple of ...

Re: What's the lowest GOM miles you've arrived home with?

I've hit zero a couple of times and reached my garage in the low singles several times, not always by choice. On a calibration run that I made running up and down my street I hit "open-contactor" about 500wh below the battery depleted warning (the amount can vary, so don't count on that much of a bu...

Re: 2015 FFE Paint colors?

Funny - most people I show my car to just don't get why I bought an electric car, ... but they all love the color,... -I guess I'll just have to accept that I live in an 'old man' community :shock: . [I was doubtful about the color before it leased it, but it's grown on me partly because of the uniq...

Re: System Off to Preserve Battery

I bought a nifty device like that for about the same reason. What you will find is that the cigarette lighter times-out after a period (about a half hour?). This was discussed in an earlier thread. For a lead-acid battery 12.7V is considered 100% SOC. The normal parasitic drain on the 12V battery is...

Re: System Off to Preserve Battery

Generally, that TSB was applied to any car taken in for the SSN recall so I'd be surprised if that's your issue. The TSB specifies .5hr, which is probably the minimum time allotment.

Re: FFE Charger Current after Fully Charged?

The battery system has a cell rebalancing mode where it supplies 100mA (@ 350Vdc [possibly with a modulating waveform?]) to the battery packs. I believe that it enters this mode when it detects cell variation > 20 mV once it reaches full charge. Generally it should not stay in that mode for long alt...

Re: Brakes making a small popping noise

jmueller065 - I'm not sure about the OP, but I think that you're describing the vacuum pump [there's no venturi effect in an electric motor] for the brake's vacuum servo. The accumulator needs to get 'topped-off' occasionally and the car fires off the pump when it thinks you might be wanting to use ...
