smokewagon Posted November 13, 2014 at 12:52 PM Report Share Posted November 13, 2014 at 12:52 PM Yesterday I drove 26 miles on EV, the HVB less then 25% in the "hybrid mode" so the ICE was about ready to start [sometimes it does at that point in my commute]. I plugged the 120v charger in and got a 100% charge in 3 hours and 59 minutes. It usually is 5hr 20min. How is this possible? Quote Link to comment Share on other sites More sharing options...
larryh Posted November 13, 2014 at 12:56 PM Report Share Posted November 13, 2014 at 12:56 PM If you enable value charge, it may partially charge the HVB prior to the Value Charge time. If you are looking at what MFM reports, it is not always reliable. Quote Link to comment Share on other sites More sharing options...
murphy Posted November 13, 2014 at 02:56 PM Report Share Posted November 13, 2014 at 02:56 PM Yesterday I drove 26 miles on EV, the HVB less then 25% in the "hybrid mode" so the ICE was about ready to start [sometimes it does at that point in my commute]. I plugged the 120v charger in and got a 100% charge in 3 hours and 59 minutes. It usually is 5hr 20min. How is this possible?How cold was the HVB? 120 volts times 12 amps is 1.44 kW. 1.44 kW times 4 hours is 5.76 kWh. I'm ignoring charging inefficiency but If the battery was cold that might be all it could take. How stable is your power? If there was one of those momentary power dropouts, where you can tell that the lights blinked, it may have aborted the charge cycle.

rbort Posted November 13, 2014 at 03:46 PM Report Share Posted November 13, 2014 at 03:46 PM (edited) the HVB less then 25% in the "hybrid mode" What does that mean? Cannot be in hybrid mode unless the HVB was at 0%. Was it at 20% or 0%? My Cmax charges 100% full on 120v from 0% HVB in about 5 hours 45 minutes, at 20% surely it might take 4 hours... -=>Raja.

There are not 2 separate batteries, 1 for EV only driving and 1 for hybrid driving. There is 1 battery and a % of it is reserved for hybrid mode. So Smokewagon is just saying the hyrid portion of the battery (on the MFM screen) was down to 25% of its available power (i.e. really low, below the 50% that is typically maintained).The HVB never gets to 0% charge, that would be extremely detrimental to the battery.

Hybridbear Posted November 13, 2014 at 07:01 PM Report Share Posted November 13, 2014 at 07:01 PM Seems quite fast. I think Murphy might be on to something with the battery temp question. Although, we've found that the car always charges faster than Ford says. The Energi takes 2 hrs & 5 mins at most and usually an "empty" battery takes 2 hrs & 0 mins to 2 hrs & 2 mins. An "empty" Focus Electric battery takes under 4 hours even though Ford's spec is around 5 hours. Quote Link to comment Share on other sites More sharing options...
Hybridbear Posted November 13, 2014 at 07:03 PM Report Share Posted November 13, 2014 at 07:03 PM The car also charges faster than the prediction in MFM. I believe the Ford engineers designed the charge time prediction algorithm to mimic a worst case scenario in terms of other electricity draws, such as battery thermal management, and thus the car almost always charges faster than predicted.

smokewagon Posted November 14, 2014 at 01:19 PM Author Report Share Posted November 14, 2014 at 01:19 PM After driving over 26 mi on the HVB it was completely dead, temps here were 75f the last couple days. I duplicated the same cycle last night and it took 5hr 17m as usual so I guessing it was a MFM fluke. I will watch it close the next few days. smoke Quote Link to comment Share on other sites More sharing options...

Was it at fairly low speeds, below 40? Quote Link to comment Share on other sites More sharing options...
smokewagon Posted November 14, 2014 at 08:35 PM Author Report Share Posted November 14, 2014 at 08:35 PM My speeds vary from 35 mph to 50 mph. I have gotten 30 mi on EV before, with temps in the 80s.I always use eco cruise.I bump it down 2 clicks going up hill and bump it up 2 clicks going downhill.I use climate "vent" most of the time. But you got to have clean glass. pitaTire pressures: left 39 psi, right 40 psi.The car is usually warm when leaving the house. I have an attached garage with a south facing door and the sun warms up the slab all day.I do use the EBH in the winter, set on a timer for 2.5 hours just before departure. [ off peak rate 5.3 cents ]I just started using the "L" selection on the shifter, it works good in a parking lot with 8 speed bumps. smoke, Quote Link to comment Share on other sites More sharing options...
stevedebi Posted November 14, 2014 at 11:14 PM Report Share Posted November 14, 2014 at 11:14 PM I think you are the first person I've seen who uses different PSI on the two sides. It makes sense in some ways, if only one person is to always be in the car. For those who may wonder, at that charge rate, you are using a level 2 (220v) charger. Thanks for the clarifications!

smokewagon Posted November 17, 2014 at 02:49 PM Author Report Share Posted November 17, 2014 at 02:49 PM Different psi is to account for road slope.You are always turning left. smoke Quote Link to comment Share on other sites More sharing options...
