Hmm, what happened to "L" mode?

[DYohn]

Hmm, had a software update last night, no PowerUp number just something about "improved DC Fast Charging" referencing a Priority Update number. Got in car to drive this morning and it had charged to 100% rather than my normal 90% (not unusual when software gets updated) but when driving in Engaged, the "L" mode now does not engage. Pressing L while driving seems to do nothing. Not acceptable... Any ideas how to reset?

Probably because you charged to 100%, L mode is disabled until the battery drains to 95%. You should be using one-pedal mode and not L if you want proper regenerative braking with the brake lights going on automatically.

Thanks for that. No, I don't like 1-pd and will stick with what I've been doing for the past 2 years. Actually what I've been doing since 2012 if you count the prior electric cars. I must have missed the 95% requirement but it makes sense.

I must have missed that requirement too. Over 73k miles so far and L has worked normally irregardless of State of Charge.

Yea there is nothing in the owner's manual to support this.

Regen doesn't work when there's nowhere for the power to go. When the battery is full it can't take any more power, so almost no regen at 100%.

Agreed. Such scandal with this L button lately.

Yeah. I'll bet Clara Ford never resorted to that new-fangled One Pedal Drive BS!

It's well established that 100% SOC still leaves headroom in actual battery capacity, so there is no reason why regen does not work at 100% based on battery being "full." Indeed, in the past at 100% regen modes in my car worked fine, and like I said there is nothing in the owner's manual about 1-pd or other regen modes (including standard regen braking) requiring a SOC below 100%. It's only after this latest software update that something was amiss. As an aside, this update also wiped out my PAK settings, car connectivity, and probably a few other things I have not discovered yet.

I am driving across town today and will do a proper test of regen modes.

the "headroom" in the battery is on the bottom end, not the top. think of it as a reserve.

There is also headroom at the top to prevent a battery sitting fully charged.

Thinking about it, even WITHOUT a top buffer, you should still be able to roll out of your garage with 100% and still be able to use regen. Why? Because to get the car moving you have to use power, draining your battery a little, so it will no longer be full.

Of course, I guess Ford could have programed it so that if the battery is still reading '100%' (which mine does even after several miles of driving) it won't allow regen.

Did you actually verify regen was happening and not just blended braking? You won’t be able to tell the difference without a scan tool. It will feel and slow down about the same.

Even if you drive a mile from 100% you can’t put full regen back into the pack because that would overvolt the cells. Only a small amount of regen is safe at very high SoC.

What if you live on top of a hill?
