quries for a battery driven car
I am a doctor by profession but reading about fuel prices and pollution got me in this
i use a electric scooter for last two years and its fine for my daily work as well as for my part to keep earth clean
i want to ask if i put a calcium calcium battery to run a 1000kg gross weight car with a800 cc petrol engine
firstly what battery power i need
secondly at asteady speed of 80kmph will the dynamo can recharge the batteries sothat the speed can be maintained
thirdly what i felt with the scooter was the acceleration and decelaration used lot of battery power so for that can the petrol engine be used for these two and then on steady speeds the car shifts to the traction motor Battery driven technology
if some one knows please answer
Re: Queries for a Battery-Driven Car
0. Also see the other side of global warming and pollution. To begin with, follow this link: http://www.google.co.in/search?hl=en&q=Ayn+Rand+Institute+Global+Warming&meta=. You might use "pollution" in place of "global warming," too.
1. About electric car: I presume you are from India (probably from Maharashtra). If so, see http://en.wikipedia.org/wiki/REVA and the links therein, esp., http://www.revaindia.com. In any case, do have a look at: http://en.wikipedia.org/wiki/Electric_car
BTW, I am not familiar with the Ca-Ca battery technology itself.
2. About recharging. I am amazed at the frequency at which this idea comes up any time electric vehicles are being discussed. Anyway, to answer your query: Your idea violates the second law of thermodynamics.
3. The so-called hybrid cars (of a very reputed Japanese make) were recently introduced in India. They made it work for cars. However, for a scooter, I think the idea may not be so appropriate. In fact, it might make the scooter somewhat bulky, and so, less efficient in using either kind of a drive. Further, recharging a low kVA battery like the one they have in a scooter, using the usual household electricity sockets, would not be a major issue. If the availability of electricity is problematic, and if you must have an electric vehicle, then, for a higher cost (i.e. after discounting the usual subsidies given for the household electricity and taking the burden of non-economy of scale), rather than mount a petrol engine and a dynamo on a scooter, it would be better to use a stationary gen-set like what they routinely use in shops in India.
4. As an aside, I had some ideas to try out in cooperation with a doctor---ideas related to diagnosis, instrumentation and computerized signal processing (like, say, FFT or wavelet analyses). If interested, please get in touch, giving your contact details.

Hi Mr Katarkar,
Good to see a technical brain behind a Doctor. your Idea of recharging while driving is a possibility, the only difference is the way its looked.

GM Goes Beyond Hybrid: Chevy's Electric Car
To show that it’s thinking well past the plug-in hybrid Saturn Vue that it announced in L.A.,
General Motors revealed its first E-Flex system vehicle here today, the
Chevrolet Volt. Though the electrically driven Volt uses a small
gasoline engine to charge its lithium-ion battery pack,
the car is not a hybrid. The Volt only runs on electricity. The battery
pack is recharged via either a wall-outlet, like a “regular” electric
or plug-in hybrid, or an on-board generator.
When
running full electric, Volt can deliver about 40 miles of driving and a
top speed of about 100 mph. However, with its 1.0-liter turbo
four-cylinder driving the 53-kW generator to recharge the batteries,
range increases exponentially: GM claims 640 miles. The carmaker plans
to introduce future versions of E-Flex with other power sources, such
as hydrogen fuel-cell stacks, to keep the battery pack recharged.
I think you would have to wait for some time till the battery technology gets refined.
Cheers!
