#1522 of 1586 EV Battery -- ThunderSky by marketdisc Jan 30, 2008 (9:31 pm)
I have a few questions about batteries for Electric Vehicle, especially by Thunder Sky (TS):   1. Is it really viable? I choose a TS product:   MODEL NO：TS-LFP90AHA   Nominal Capacity ：90AH   Operating Voltage：2.5V～4.25V   Weight：3kg±100g   Dimensions：145×220×68（mm）   Let me assume its votage is 4.00V, then the capacity of a battery is 4V x 90 Ah - 360 Wh. I know a 1.2ton-car driving at 100 km/h needs power of about 13 kw. Then a TS battery can drive the car by 360 Wh / 13 kw= 0.08 hours, i.e. 2.8 km. So to drive 280 km the car needs 100 pieces of batteries, weighting 300 kg. But it is unlikely to drive a car with 300 kg batteris. Was my calculation correct?   2. May I know the installed-based for ThunderSky automobiles, especially in Europe in 2005-2007? Who are its main customers? What sale growth do you expect - Any committed contract?   3. What's the difference for batteries used on Fuel-cell EV, Hybrid EV, and Battery EV?

Replying to: marketdisc (Jan 30, 2008 9:31 pm) No, your calculations are exactly right. Most EVs have a thousand pounds or more of batteries and the makers extrapolate their best case scenario and then multiply it times the battery capacity to get "mileage".   Real world, it's often 1/2 of that.

Replying to: marketdisc (Jan 30, 2008 9:31 pm) Your best bet is to talk to others who have used the Thunder Sky batteries in their EVs. Here's a page with several of them:   http://www.evalbum.com/battb/THUN

Replying to: marketdisc (Jan 30, 2008 9:31 pm) 1. yes batteries are heavy, but the main problem at this point is cost.   2. sounds like you want someone to do investment research for you. contact the company or other sources.
#1526 of 1586 Mitsu finally has a car on the road by larsb Feb 14, 2008 (5:52 am)
This looks like it really might happen:   Mitsu MiEV coming soon to Japan, then the UK? USA when?   When it comes to city cars, the Splash is the future for Suzuki – but can the same be said of Mitsubishi’s new i? Powered solely by electricity, it doesn’t emit any CO2 on the move and sprints from 0-60mph five seconds quicker than the petrol version.   Called the i MiEV (which stands for Mitsubishi innovative Electric Vehicle), the car goes on sale in Japan next year and could make it here after that. Auto Express took a drive to see if it really is a glimpse of tomorrow’s world   Apart from the stickers and a plug-in socket, the exterior is identical to the regular i. Inside, the only changes are the addition of a battery meter, while the auto box is swapped for a selector with two modes – Drive and Eco.   Out goes the 660cc three-cylinder turbo petrol engine and in comes an electric motor running off lithium-ion batteries spread underneath the seats.   Power is identical to the petrol car, at 63bhp, but torque is up from 85Nm to 180Nm. Response is instantaneous, and the i races from 0-60mph in less than nine seconds in virtual silence.   Despite carrying an extra 180kg, it actually handles better than the petrol model, thanks to a lower centre of gravity, and it rides comfortably. Drive hard, though, and the batteries will run out within one hour – which is where Eco mode comes in.   This drops power to 42bhp, and Mitsubishi claims you can travel 100 miles before recharging. Choose the special quick-charge mode, and you can refill the batteries to 80 per cent capacity in half an hour.

#1528 of 1586 slow around here.... by reddroverr Feb 29, 2008 (8:32 pm)
http://www.theautochannel.com/news/2008/02/29/079263.html   Daimler claims that they are first to get the li-ion in practical mode for autos. Don't know if that's true or not. I do know that the hybrid in the piece gets around 30 mpg. Nothing to write home about, but good for a powerful luxury car I suppose.
