Separate names with a comma.
It depends on the chemistry. There is a huge variety of lithium-ion chemistries available today, many much more advanced than the cobalt-oxide...
The answers you seek can be found by comparing figure 1 (NiMH) with figure 3 (LiIon) in this paper:...
The big gain in switching to lithium-ion is efficiency. The roundtrip of energy in to energy out for NiMH can be as low as 60-70% at high...
Re: Chevy Volt - 230MPG EPA City? Just to clarify some of the issues that have come up in this thread regarding Volt energy consumption in the...
Here in the UK, the REVA G-Wiz electric car and Smith / Tanfield electric trucks are selling like hot cakes (and profitably). It might help that...
They already exist. You can take your pick of lithium-titanate from Altairnano (charges in 10 minutes) of lithium-iron-phosphate from A123...
Not plausible? Tell that to BYD who are selling PHEVs already and manufacturing LiFePO4 batteries for less than $300 per kWh. This is just sour...
BYD have come from no automotive capacity whatsoever in 2003, to selling 14,000 units per month of just one of their models in their range (the...
A new video has been added on EVWORLD showing highway speed EV mode (up to 72 mph) in a PHEV converted Prius: EV WORLD TELEVISON: Cracking...
It sounds to me like their software patch allows the engine to spin without fuelling (ie with force from MG1/2) at highway speeds. Not an...
Sorry if this has already been posted somewhere: Green Car Congress: Software Upgrade to Prius PHEV NiMH Conversion Kit Enables All-Electric...
The quoted 0-60 time of 16s is a mistake in the article online, it is quoted as 13s in the print magazine and elsewhere. @Mike, I take your...
The new VW Polo Bluemotion is out and has just been tested by Autocar: VW Polo 1.2 TDI 75 Bluemotion - Road Test First Drive - Autocar.co.uk...
The lithium-manganese-oxide chemistry that Nissan uses has an energy density of about 140 Wh/kg. That would put the battery pack weight at around...
For interest, some other coefficients of drag: GM's EV1 electric car: 0.195 Daihatsu's UFE-3: 0.168 VW's 1-litre car: 0.159 Apart from the...
The issue is not with lithium batteries themselves, but with Tesla's approach to them. Tesla realised that they could get a high energy density...
I just read that the 2010 PHEV Prius will only be available to fleet customers and not the general public for the first several years (evaluation...
The miles per kWh figure that EV/PHEV manufacturers publish is measured on the same type of driving cycle as the standard (EPA or EU) test driving...
Excellent scoop Ken1784, well found! :) As for the discussion regarding likely battery pack size of the Prius PHEV, the published electricity...
OK, another update on the ECO4's performance. I'm just back from a long weekend visiting Wales, which was a good opportunity to see what it...
