I'm no engineer, but it seems to me that ICEV efficiency today - despite the fact that most ICEVs are (IMO) drastically overpowered - is already quite good for a piston engine, thanks to tight microprocessor control. I wonder how much more ICEs can be optimized, even when driving only a range extending genset - whether it's enough to make up for the conversion losses. With fast charging pushing into the hundreds of kW, and EV batteries typically between 50kWh and 100kWh, I see a diminishing need for true hybrids and their complexity. I think we may already be at the point where if you have access to good long distance mass transit (rare in the US, unfortunately) you can sell the ICEV. It might make economic sense for those without good trains to rent an ICEV for long trips. Or perhaps an extended family could share one ICEV among 3 or 4 households. Could, could, could. Easy to say. Now just try to convince the general public to actually do it! :-\ David Roden, EVDL moderator & general lackey To reach me, don't reply to this message; I won't get it.
