Out of gas! Electric mode?

[Jmitchelltfo]

Thanks, this was purely hypothetical. It would be a nice feature in an emergency though. My PB is currently being built so I‘m not exactly sure how the hybrid works. I understand you do actually travel a fair amount of miles (~20% or so) in electric mode but it must all be in short stretches.

VERY short stretches. ICE will kick in if your right foot touches the accelerator with more than a tickle, unless you are headed down hill.

My PB will switch between battery and ICE at least 20 times during my 12 mile commute every morning.

Highway trips are next to zero electric only, besides coasting up the off ramps.

Not sure if anyone else did it, I managed go .9 miles on a flat road while going 45 mph on EV over the weekend.

You drive it like any other car/truck. The system will flip from ICE to EV mode automatically provided you're going below 50-55mph and the HV battery has at least 50% charge. Sometimes it will enter EV mode at 50% other times it will wait till it reaches 63% charge. Ford programmed it to maintain the HV charge level between 40-63%. The range on EV mode will vary, but you can expect it to go somewhere between .3-1.2 miles depending on the driving conditions, draw on the HV battery, and HV battery charge level when it enters EV mode. Once the HV battery dips below 43% the transiton from EV to ICE happens and it will recharge the HV pack as you drive.

You get the most out of hybrid driving around the 35-45 mph range with long uninterrupted driving with minimal stops allowing you to easily hit 28-30+mpg but in most cases you'll likely see between 21-24mpg average on surface streets. When you get the truck, you might want to enable the EV coach in the cluster and use that for a few months. This will help you get a better idea of how the system behaves when in/out of EV mode. It can also help you get the most of each EV drive cycle.

If it seems like it just doesn't want to transition sometimes you can trick it into EV mode by letting up on the gas and coast or lightly pressing the brake so it enters regenerative braking but will restart the ICE if the HV charge is below 50% and you continue driving or press the throttle enough to demand a torque output higher than the EV drive motor is designed for. The transition from ICE to EV and back is seemless for most and you never notice it as you drive.

There is not a built in method to see the HV charge level, rather you would need to get an OBDII dongle like OBDLink MX+ and find an app that's compatible with Android Auto/Carplay so you can select the specific PIDs to monitor for the HV battery and display it on the infotainment screen, or get a cell phone mount to keep an eye on it to better learn the truck's behavior.

In the F150PB the 12V battery starts the engine. However, you do need enough residual juice in the Traction Battery to get the electrical stuff working. IE if the traction battery is really dead, the truck won't let you start. I have observed about 0.8 miles on the battery, level road, maybe 20 MPH.

I just dealt with a Explorer hybrid today that was ran out of gas while at idle.

Took awhile just to get it started again and it threw multiple codes and disabled some electrical parts when it finally started. It only gave me a couple of attempts before it would not turn over and I had to let it sit so it would reset before trying again.

Got it started and it said something about secondary battery on the dash but luckily after it was turned off for awhile all warning lights were off and it seems to be running normally again.

What a pain!!

I once let my 2006 escape Hybrid run out of gas while idling. The system protected itself. Once 5 gal was added to the gas tank it started right up. The one thing to be aware of is, in my experience, the low pressure fuel pump when let run dry (even for just a second or two) will fail within about 10,000 miles. So consider replacing it after a run out of gas event. As to the High Pressure fuel pump (direct injection pump) I have no background to speak to that pump.

Thanks for the information.

All of these cars a police fleet cars. So luckily I just send them to the shop for repairs.

These officers are super hard on these things and I find them left running often. Plus most are used almost 24-7 and are idle a lot.
