You look like you charge a lot with only 28 fillups in 88k miles.  I went uphill this morning keeping MADMAX just under 35 mph for 1.5 mi. with 193k miles in my Hybrid.  Fully charged I could have gotten 2 miles. :smile2:

HAHAHA...that fuelly is so old.  I guess I should pull it from my signature.  The car does get charged almost every night.

It has been awhile since I've posted in the forums, just wanted to provide an update.

 

C-Max notes = 2013 (build date of June 2013), currently has about 33.5k miles and has been charging via Level 2 since January of this year.

 

  • When I was still charging on Level 1, saw Raja's thread on how to maintain the HVB, but didn't take serious notice until I saw this thread.  In which my kw had already dropped to 4.7.
  • So between the end of 2016 until summer 2017, began following (not 100% but about 80%) Raja's outline on preserving the HVB and his various charging techniques, although on several occasions, I've caught my wife plugging in the car immediately after she had been driving on the freeway.  The capacity now sat around 4.4 - 4.5.
  • From summer of 2017 to current, I get a constant 4.3.  Every now and then will get 4.4, and once got 4.5.  Lowest I've seen has been 4.0 - 4.2 (i had gone 3 weeks w/o checking tire pressure thus it was low, usually keep my tires inflated to around 45/46 psi).
  • So currently still getting around 4.3kw, my range still getting 19 - 22 AER (when the car was new was getting 23 - 26 AER, with a best of 27 once).  And my routes hasn't changed since then, but we've had few road trips.

 

I also wanted to point out to those "new" to PHEVs and BEVs, do extensive research on the thermal management system ((TMS) how the batteries are cooled).  Vehicles like Teslas, Bolt, Volvo XC90 T8, Focus EV, uses liquid cooled technology for the TMS, thus constant charging and heat will be less of an issue in regards to degradation.  In the C-Max and Fusion Energi, it's air cooled, thus heat is a huge factor in battery degradation.  Think of it like your pc/laptop/tablet/cellphone, constant recharging or leaving it plugged in causes serious degradation to the battery and eventually it may not hold a charge (don't think this will ever happen to our cars).
