Replying to: gagrice (Nov 12, 2007 6:25 pm) Enerdel's battery technology is similar to Altairnano's, no Cobalt or risk of thermal runaway. They also claim that the price of these battery packs will be low enough to allow for drivers to recoup the initial price premium of an EV within 2 years. We'll see but it sounds pretty good.

Replying to: tpe (Nov 20, 2007 5:29 am) Let's hope so, but that statement in itself is pretty vague. Do they give what they based that statement on? I looked at the company. Tiny little thing...perhaps..perhaps.

Replying to: reddroverr (Nov 25, 2007 2:37 pm) "Lithium ion batteries developed by the German company called Li-Tec, which is taking part in a development program with Bosch, "take up 30% less volume than those from Toyota" and "allow you to go three times further for the same weight than French models, " according to Li -Tec director Tim Schaefer. Li-Tec’s ‘Separion’ system consists of two lithium electrodes in an electrolyte, separated by a flexible ceramic membrane that reportedly provides greater thermal stability than has so far been achieved in lithium ion batteries. Their tendency to overheat is what led Toyota to delay installing li-ion batteries in the forthcoming third-generation Prius hybrid. Other consortia besides Bosch are also developing lithium ion battery technologies focused on thermal control." http://puregreencars.com/Green-Cars-News/Technology/Li-Tec-Reports-Lithium-Ion-B- attery-Breakthrough.html

Replying to: reddroverr (Dec 12, 2007 1:07 pm) toshiba Not a lot of specifics in this article other than a 5 minute recharge time and 10 year lifespan. The field of companies conducting R&D on advancing battery technology is definitely getting crowded. |

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? |
