Separate names with a comma.
It's true that BAS has provided only minor mpg improvements but there is nothing inherently poor about the efficiency improvements in the 2-mode...
Right. Wrong. I agree that "blended" gas plus electric numbers like the ones reported for PHEVs like the Energi and Volt by CR, NEDC, and Fuelly...
True, but the Prius mpgs are so much better that it's not much of a comparison. There is Prius, and then there is everyone else.... :)
Today's new numbers are: C-MAX hybrid 42 city/ 37 highway/ 40 combined 100 MPGe EV combined C-MAX Energi 40 city/ 36 highway/ 38 combined 88...
The lowest regen braking efficiency number I've seen for a modern plugin car was 39%, supposedly in a LEAF manual, but this may have included...
Probably not. Acceleration and speed are mostly limited by the power output capability of a 4.4 kWh Lithium Ion battery pack that can fit under...
So, you're going to slip the green kayak under the driver-side wheels and the red one under the passenger wheels and then sit on the roof with a...
You just noticed? :)
The MM buffer is very unlikely to run out. It was sized to be good to go up the most demanding mountain passes in the U.S. (North America?). If...
The 25% of the Volt battery reserved by MM is all usable so it's really 150% of the usable portion of the PiP battery.
Regenerative braking like that should be at least 50-60% efficient overall and possibly a bit higher. The losses going through the motor,...
I have little experience with 3rd gen Prius driving in serious mountains but I imagine it should be better than my 2nd gen 2004 Prius and it does...
The Prius Plugin normally only drains the battery down to the low 20% area (23%?) so it uses about 85% - 23% or about 62% of its 4.4 kWh nominal...
Right. MM should set aside a reserve of about 4 kWh (15 miles on a flat road at 60 mph or 150% of the usable capacity of the PiP) that can be...
Right. It sets the minimum target SOC of the battery to about 45% instead of the normal 22%. The engine will try keep it there but the motors can...
MM isn't really needed for driving up long mountain roads at 55 mph. It's needed for driving up the longest and steepest mountain passes at full...
This statement about high altitudes and Prius-style Atkinson Cycle effectiveness is new to me. I'm skeptical about it because a lot of folks are...
I calculated my commute in my 2011 Volt today: 98.5 miles EV at 121.6 MPGe 26.5 miles HV at 51.94 MPG 125 miles total at 94.7 MPGe overall 245...
It takes about 15-20 kW to go 60 mph steady and about 25 - 30 kW to go 70 mph. Maybe 45 - 55 kW to go 100 mph. 75 kW is equivalent to 100 hp.
The NiMH battery used in the regular Prius is usually kept in a narrower charge range of around 40-60%, I think, although they sometimes go...
