MPGe is based on energy density. it is not a simple addition. A volt has
98MPGe, 38 EPA AER with 38 MPGcs (MPG charge-sustaining)
【在 g*****o 的大作中提到】
: 现在 EPA 的新标法？
: 这基本就是 25 e-mile + 34 MPGGas

not sure about the battery SoC (state of charge), charging speed is somewhat
on the slow side.

230V有的车是2.8-3kw,有的可以到5kw.

assuming T8's battery is on-par with other EV batteries, roughly 4miles/kWh,
then 25 AER translates into 6.25 kWh usable range out of the 9.2 kWh total
capacity (SoC=68%), then charging 6.25kWh with 12 hours on 110V is twice
slower than, for example, a volt (10 hours charging 11kWh out of 16.8kWh
capacity). This is similar with L2 charging.
unless the 9.2kWh number given by goVolvo was the usable range.

发帖数: 26623 | 9 风阻其实不应该比CMAX高太多.CMAX高/宽是1588*1825,老XC90是1784*1935,多出20%,但
是59mpge的话电耗比CMAX高50%.而且CMAX已经3800磅了.

interesting ... I haven't paid attention to MPGe, but this makes sense.
however, EPS's numbers are underestimated for my driving habits. my car
achieves the EPS estimate (0.292*98*10.8=31 AER) only now when the outside
temperature drops below 0C.

finally, I measured the total charging power consumption using a kill-a-watt
. to charge a depleted battery to full for my volt drew 13kWh power from the
outlet. as my usable range now stables at 10.8kWh, that gives me a 83%
charging efficiency.
if I use this numbers, the EPA estimate becomes 0.0292*98*13=37.2 miles, I
guess that's where the 38 AER rating came from.
