Hi Ryan, This is not our Cal Cars group, although Ron Gremban does have some Energy CS CAN bus equipment in his prototype Prius PLUS. Cal Cars is a non-profit...

Outside of D cells, we have found only one NiMH product that looks good for the PRIUS+: Saft's NHP10-340 -- a 12V, 34 Ah, 6.7 milliohm (1.8% V sag/C), 8.7 kg...
1. The state of CalCars’ NiMH battery pack 1.1. Procurement status 1.1.1. With the exception of the Saft NHP10-340, which is not in volume production, and...
In general, I have refrained from posting messages here that are also posted at CalCars-News. But because this contains significant new information from EDrive...
... I'm glad to hear you're comming arround! Deep down you knew all along, didn't you? ... Here's hoping Toyota has seen the light at the end of the tunnel and...
Thanks Ron for that very complete report. It was comprehensible even to very untechnical me. Sounds like all the lawsuits, etc pushed the market right past...
... Per my recent posts in the yahoo/EVWorld.com group, another factor that has emerged even more clearly has been the worldwide licensing policies of ECD with...
PS, in response to your request for feedback to the post-script: I would be very very enthusiastic about a Ford Escape+ PHEV. Four good things would be: 1. a...
Ron: This is a good summary of the state of the practical battery options as they exist today. I'm glad that you have done this work, but as I said in the...
I HAVE a Ford Escape (very happy with it :) ) I might be willing to put it under the knife -- but we can figure that out later.... I think a Ford Escape is a...
4. Oddly, a car getting 30 mpg (instead of 20) saves more gasoline than a car (like a Prius) getting 45 mpg (instead of 30). -Jim Only if you look at it as...
Bruce, No argument from me on this! :) I wasn't trying to violate any laws of physics!! I guess what I meant was that a car at a lower MPG has a broader ...
By the way: We have already demonstrated in a Chevrolet Suburban that we can have a Plug-In Hybrid with 60 miles of all electric range before it becomes a ...
... OK, suppose a million people own the first type of car and a million people own the second type. You have the resources to get one type of car from the...
Whew--12 posts in a row, most of which, alas, are not on our main subject: the PRIUS+ project, its technology, and to some extent, its technical-strategic...
Of course, you're right, Richard. As you probably realize, the cost of advanced batteries in low volumes is the primary price determinant. That's why we are...
... I tried posting to gridable hybrids but after five days of waiting for two of my posts to appear, or for the moderator to respond to my enquiry, I have...
Let's assume batteries can be had for $300/kwhr (an optimistic, but hopefully realistic assumption). Assume they are good for 1000 cycles. Then that means...
Sorry, I neglected to post this message to the PriusPlus group, you may find it of interest... Subject : "Battery breakthrough threatens fuel cells?" In short,...
Note: I still plan to respond soon to all the responses to my recent battery and possible future directions post, but first: new news! Late last week I...
The Maxwell ucaps have a capacitance of 350F at 2.5 Volts. They are the size of the D-cell, but as Ron says, a bit lighter. Their energy storage is .5CV^2,...
I certainly agree with the notion of keeping an open mind toward UCaps, either Maxwell's or those of any of their worthy competitors: A few comments about...
I've just roughed out a spreadsheet for my school work. If anyone is interested, I can post it, but give me a month or so to clean it up.... It tries to...
In response to all your comments, here are a few more of my thoughts on supercaps: * The major reason for investigating these Maxwell supercaps is that they...
Interesting: the analysis seems simple enough to do but a spread sheet and the assumptions seems interesting. when you get it done, could you email the spread...
... I wonder if these equations absolutely must be the case? Must we expect the caps to function from 0-60? If they can help with acceleration from 0 to 10 or...
