Honda Civic Pluggable-feasible???

Re: Honda Civic Pluggable-feasible???
Using EV mode for long periods then using the ICE (from a cold start) would produce a lot more pollution because of cold engine components including the cat converter.
Maybe during highway cruise speeds the ICE could be run at a constant 1500 rpm and power a small generator that powers the electric drive motor. Less pollution, less fuel, more efficiency. Sort of like a diesel-electric locomotive???? Then just run on EV mode in the city from a LIon battery pack.

i wrote the guys at CalCars, who do the Prius plug in conversions and they said the Civic was not really an option. he listed most of the reason given here actually. Prius can just put out more power from their electric motor.

The motor and the the crank shaft are connected together and the system needs a lot of power to spin the crank shaft by the motor.

My bet is we need at least 2 or 3 kW of battery power just to spin the crank shaft.
What a wastefull system!
I agree Ralph's concept, a plug-in series hybrid.

But calling it wastefull is a bit over the top - if not fanning the flames between Honda and Toyota owners.
Many will agree that the Civic's IMA is more than meeting its objective of lowering oil consumption and polution. At this point, Toyota's system has not proven to be significantly better despite being significantly more complex.
Couldn't we just agree that both systems are excellent demonstrations of real progress in automotive technology, and that having more of both is only better for us all?

My comment about "wastefull" is for the converted plug-in vehicle which runs most in electric only mode. I just would like to tell the Honda IMA system is not a good candidate of plug-in.

Re: Honda Civic Pluggable-feasible???
using the current motor on the hch, i could see a plug-in modification as useful. i think it would provide a significant boost to city mpg. my experience shows that it is pretty easy to drain the battery (at least down to 4 bars when forced regen kicks in) in normal city driving. i believe a fellow hch driver did some tests that show that for each bar of forced regen there is a 10% drop in mpg (don't quote me on that but it sounds reasonable). the hch does phenomonally well at highway mpg and pretty darned good at city (can usually get at least 40mpg in city driving without really trying). a battery pack that gave enough reserve juice that eliminated all forced regen and boosted electric assist on acceleration from stationary could theoretically bump the hch's city mpg up by more than a modest amount. those two factors alone account for the hch's big hits in city mpg.
hmmm, any good electric engineers out there who are willing to mod an hch and try it??

Go see the movie "Who Killed the Electric Car", at select theaters now. You'll understand better why no mass production EVs are currently being offered by any auto manufacturer. It's a crying shame.

Hey, that's already how HSD works!
