Power in Kw creates from Regen

[MadMatt]

I searched, didn’t see. Is this able to be seen with a OBDII scanner?

whats the peak energy in kw regen created from a 60-70mph highway decel to a full stop.

reason I ask, high charge/discharge should be avoided in sub zero Celsius temps. Does aggressively using regen affect the battery negatively?

Yes. Peak regen is about 85 kW on the extended pack with a warm battery. Yes, the amount of regen should be limited when the battery is cold. However in practice Ford's strategy with the NCM batteries still allows an excessive amount of regen, up to 60 kW when the battery is at -10ºC. Most other manufacturers severely limit regen when the pack is that cold, but not Ford. It is unknown how much long-term damage this is causing to the packs. The regen limit at -10ºC should be more like 30 kW or less instead of 60 kW.

The programming on the LFP pack is better, from what I've heard it does actually limit regen to minimal levels when the pack is cold.

I've got an LFP, can't say I've noticed a difference however my car is parked in a garage so the majority of the time my trips start with a battery around 10c.

There's no way to limit regen on our side though right? from what i understand, the 3 drive modes affect how aggressively regen kicks in but they all hit the same total power after 3-4 seconds.

If you have LFP you should be fine, the car will limit regen for you. LFP also has a greater ability to keep the pack warm, so it should be less of an issue.

With the NCM packs you have to be more careful about fully letting off 1PD when the pack is very cold, or decelerating in neutral to disable regen.

This brings up an interesting question, We/you know what happens in an ICE vehicle when you accidentally put the tranny in reverse while traveling forward at speed(ouch), what happens in an EV if you do that by accident? Occasionally I put my Mach-E in neutral when braking to help clean up the rear brake rotors and the though has crossed my mind.

You can limit regenerative charging in the same way that people with 1PD limit braking: Lightly apply pressure to the go pedal. It requires practice and some concentration. There is currently no way to change Ford’s default maximum in software. ??

If you put it in reverse while driving, since there’s no transmission (direct drive motor), it won’t do anything but show you a warning on the screen. Once you slow down to something less than 15 miles an hour, then you’ll be able to apply reverse torque even while moving forwards.

The only thing you need to be careful of is not shifting it into park while moving because that could damage the park pawl. But R N D are safe while in motion.

Or throw that sucka' into neutral!

Wouldn’t that be “dat sucka”? ??
