Talk:Electric vehicle
From Silent Revolution
Hey, ive got a few bits to add, that are often discussed or NOT discussed at all. First, here is an excellent report on current Japanese strategy for city commuter EVs http://www.electricdrive.org/index.php?tg=fileman&idx=get&id=36&gr=Y&path=&file=Ishitani.pdf
covers the alliances, the technologies, etc.
Another thing, in your discussion of fast charging : lots of people bring up the point that often the rated power circuit is not available for fast charging, which completely forgets any _charge buffering_. For instance, if you had a solar fast charge station somewhere in the middle of the desert, you would obviously have some economical means of holding the charge, like flywheels ( already in widespread use for grid load balancing and backup power ) that can deliver huge bursts of power. Similarly, if you HAD to have a fast charge option at home or at your fleet park you could d buy some spare stationary storage capacity without uprating your installed line power.

[edit] Shouldn't "energy density" be "specific energy"?
Technically? I've heard them described as "volumetric" versus "gravimetric" densities before.
Since regular "density" is mass/volume, it seems strange to transform that into energy/mass. Much more sensible to make it energy/volume.
"Specific-" always describes the quantity in question in terms of mass, however.
[edit] LiP or LFP?
In "Battery maintenance", it is said that A123 lithium iron phosphate (LiP) batteries, for example, are good for over 7,000 cycles.[1] According to Wikipedia:
- LiP = Lithium-ion polymer
- LiFePO4 or LFP = Lithium-iron phosphate
The linked document does not specify what lithium technology is being used, so I don't know which is wrong, the phosphate or the abbreviation.--87.162.33.113 06:03, 28 January 2009 (CST)
[edit] Two small points
First, by using CFL bulbs etc I am saving enough electricity to power an EV (when I can get one). The savings in gasoline would be pure greenhouse gas savings.
Second, I like the idea of having an EV with enough batteries for local driving. For long distance, rent more batteries near the start of the journey and drop them off near the end. Not only would they power you for the journey, but would recharge your built-in battery as well. And they can be recharged when power is cheap.
