I have an idea for an electric car that although is not new, I simply
have not seen anyone go in this direction. Since I am only a hobbyist
type of engineer, I and embarrassed to ask if perhaps I am barking up a
wrong tree. Please bear with my ignorance as I ask a few simple
questions and give you a brief description of my ideas.
I do not like the current crop of hybrid cars. although the technology
is better than nothing at all it is only a minor benefit over none at
all, and frankly almost all the hybrid cars would be better off as a
efficient 4 cyl car, without any electrics.
I think they (the car manufs) have it all backwards. I envision an all
electric driven wheel car, with a small 200-400 CC engine running on any
type of fossil fuel (Diesel propane, natural gas, and or petroleum).
this is a small unit designed to run at the most efficient speed (2500
RPM). It runs all the time it is needed to charge the batteries and
also runs the Air conditioner, and any other "power" accessories that
might be needed.
The batteries would be of efficient lithium ion type (probably 1-2
thousand of them). they could be arranged into any needed voltage
levels. As well as the battery power and the electric engine (Could be
dc or AC brushless) there would also be a shared shaft DC engine with
completely different winding sharing the same shaft as the primary
windings. what this secondary winding would do (Either AC or DC) would
be to kick in when a large boost in power (initial acceleration and or
passing at hwy speeds) is needed. I would like to ask if there is any
large capacity capacitors that could be used to store energy and allow
for a dump of 3-7 seconds of boost. Are capacitors available that are
small. lightweight, and of sufficient size that they could be used in a
gang style connection?
The little 200-400 CC engine could be run all the time or only when the
caps are not full. The little engine would first fill the caps, then
maintain the caps charge. After that the engine would charge the Li ion
cells. It is also able to take a charge from the AC wall outlet, so
that during the night your car would be fully charged. The little engine
in the back could be used to charge when an AC wall outlet is not
available and of course during the operation of the car to recharge the
caps. What I really want is a minimum 20 HP equivalent from the main Li
Ion batteries, and a 50 hp boost as the caps dump to the booster winding.
Does any of this make any sense? I do not know if I am describing it
properly, and I beg your indulgence re my lack of formal engineering...
But I am reasonably capable of machine shop use, and I have a couple
of "well off" friends who might be interested in funding a prototype.
Whet I do not know is if such capacitors exist in the size and weight I
might need.
Any ideas, would be appreciated...
If you could.... A CC to my email address of [email protected] would be
appreciated....
Thanks in Advance.
