This is my data sheet for a 1,000 mile plus run between refueling for our Ford C Max Energi which has a 20 mile range on electric drive only. In it I compare the ICE and the EV efficiencies, then at the end I report on the system using 1/3 ICE and 2/3rds EV.
1,011.6 miles 671.4 EV mi 66.37% 340.2 ICE mi
104.7 mpg 162 kWh 199.26 kWh 6.079 gals-e
(97.62 mpg actual gasoline 10.362 gals/April 11th, 2017)
10.362 gals + 6.079 gals e = 16.411 total system gallons
EV 671.4 ev / 6.079 gals ev = 110.445 mpg ev
ICE 340.2 ice / 10.362 gals = 32.831 mpg ice
PHEV 1011.6/16.441 gals e = 61.53 system mpg e
1,000/1011.6 = .988533 MBTU’s
1,000/663.7=1.5067 x 6.008=9.052 g-e = 1.01236 MBTU
1,000/336.3=2.973 x 10.243=30.452 gal= 3.40562MBTU
EV 9.052 gal x 32,777/miles = 297 watt hrs. Per mile
ICE 30.452 gal x 32,777/miles= 998 watt hrs. Per mile
EV cost $15.94 per mile $.023 per 0.1K mi $2.37 per 1K mi $23.74
ICE cost $22.79 per mile $.067 per .1K mi $6.69 per 1K mi $66.99
Cost / MBTU / kWh’s normalized per 1 K mi 1/3rd ICE and 2/3rds EV
EV $15.86 .6749 MBTU 198 kWh’s [totals $38.19, 1.8101 MBTU]
ICE $22.33 1.1352 MBTU 332.6 kWh’s [total 530 kWh’s per 1 K mi]
16.1698 system gallons e, 61.53 mpg e composite average.
