Re: [EVDL] Electronics help anyone
You're going to roll your eyes when I suggest this, but you will thank me later when you do this simple project using one: Run the gauge with an Arduino. The version you will need costs maybe $20 and will do this job simply and easily. Once you get a single project working using an Ardunio, (which will take a bit of work on your part at first) you will be amazed how easy it is to use and how many little projects will be simplified by using one. 1) Get this book and kit: https://www.sparkfun.com/sylviakit (Book is written by a 12 year old girl.) 2) Read the book. 3) Do the simple programs and experiments with the kit that the book tells you, step-by-step, _exactly_ how to do. (This book assumes you know _nothing._) 4) Write a simple custom program for the board (or look up a program for the board on line and simply download it) that solves this particular problem. 5) Install the board in your car, connect it up, and you are done. You can get a much smaller, cheaper, specialized Arduino to do this specific job, but the more generic Arduino "Uno" in the kit will work. There are Arduino's _everywhere_. For example, our Taz 5 3D printer that has all sorts of things happening at once, like three axis motion control, two temperature controls, a variable speed fan, a digital display, a digital knob that controls a menu on the display, reads commands from a computer via USB or runs commands from an SD card, plus things I have forgotten, runs it all _simultaneously_ on an Arduino board that costs about $80. Trust me, if you do this you will be astounded at how simple the whole thing has become and will never look back.

I hit a dead end at edmunds.com. Looking there I find not the 2/3 figure, but an even worse one -- 72.5%. Important distinction though: the Edmunds article is referring not to just EVs, but also to hybrids. Absent any further elucidation on their part, I take that as all types including those which don't plug in and use only liquid fuel (gasoline/petrol). They lump these all together as "alt-fuel," which is bogus unless you somehow consider "not coal" or "not wood" an alternative fuel. That puts things in a different perspective. For your average vehicle buyer, it doesn't take much effort or commitment to switch to a "hybrid" which acts just like a conventional car except that it uses less fuel and doesn't idle when stopped. So, fuel prices have gone down, and folks who bought (probably mostly) Toyota Prii when fuel prices were higher are switching back to -- it turns out -- by and large, small SUVs. Big deal. More: Edmunds doesn't cite their sources, which makes me a little suspicious of this number. So on further research and reflection I have to conclude that there's probably nothing much to see here. If you'd like to read the original article, search for "Hybrid and EV Loyalty Plunges Due to Low Gas Prices."

[EVDL] Thanks for the Smart ED, iMiEV and Leaf Info
Thanks Cor, Dave etc for the thoughtful Smart, iMiEV and Leaf info. Since I already have a Leaf (like it very much but my son latched onto it and would like a smaller commuter car) when I replace my Karmann Ghia EV next month I'll probably buy a iMiEV since I see online service manuals available, individual battery monitoring and the same 100K 8 year battery warranty like the Leaf has (also saw a few Chevy Spark compliance cars but little support). It looks like according to www.batteryuniversity.com that both vehicles(Leaf & iMiEV) use the NMC nickel- manganese- cobalt cathode with lithium substrate and carbon anode by LG Chem? I think the 2016 Smart will too. So the iMiEV should have similar life and both air cooled not complicated water cooled like the Smart ED. I drove a Smart ED and really liked the car but if I can't service it (or get it serviced for a reasonable price) then it's a no-go. I wish Swatch kept it or sold through another company other than Mercedes Benz (most MB wheeler-dealers hate the car - low profits), rather sell $70K foo-foo Mercedes (like the dealer here in Roanoke, VA). I'd take the Smart (convert) plunge if someone made a motor adapter and had a manual transmission but the one's I've seen (ICE) have a crappy auto tranny. I saw an 05' conversion on www.evalbum.com but looks like he spent considerable time and money on it (like my conversion $25K). I'm looking at a iMiEV 2014 5K miles for $9K ... Still hard to sell my conversion - since it'll probably be the last car I'll convert, doesn't make sense to convert anymore though. Mark - Hi folks (original message) I was wondering if it makes sense to convert a Smart Car and does anyone know of a good conversion kit? The problem with the Smart ED as I was looking at a used 2014 is they want a $80 monthly battery rental fee for ten years or $9600 on top of the car price. Also there is *no* service manual available from Mercedes. I called several Smart dealers and they said their service department can't even get a service manual. Also I can't find any way to monitor the individual cells like my Leaf or iMiev And If you buy the battery for an additional $5k the warranty is only 4 years and 50k miles. Battery replacement cost is $29k verified at several dealers. The Leaf and iMiev are 100k 8 year warranty and the Leaf is $5.5k to replace and the iMiev is about $12k a dealer said. I'm thinking of selling my Ghia www.evalbum.com/4346 and buying a used iMiev or Smart ED. I already have a Leaf that my son drives mostly and both EVs are charged from the sun.

Message-ID: Content-Type: text/plain; charset="us-ascii" Everything screams to me that the Smart is a nice car for Leasing but stay away if you want to buy! Every car is going to be an orphan as soon as you buy it and it has very limited space so unless you are lucky with the car and the battery and nothing breaks - it appears that you are on your own or have to fork over whatever ransom Mercedes asks to work on the car for you. For proof, look at the unrealistic battery price, it is several times more than the cost of the battery, so why bother if there are so many better alternatives? I love my Leaf so much, I now have two. Since I need space to work on my electric truck, I am going to sell one. It has some damage but hardly noticeable and does not affect the operation at all. Good battery, still has 12 bars though I suspect will lose bar 12 soon. Car is a 2011 Leaf SV, battery has lived in Washington until 3 months ago when it moved to California, that is why it still has good capacity. Send me an email if you are interested.

Re: [EVDL] Smart Car Conversion Kits?
Someone must have put a light body on a VW pan. If you skip the transmission using hub motors possibly 4 3000 watt units I suspect you could have a very functional and long range EV on a small pack. Total weight though has to be near 1000 pounds. Lawrence Rhodes -- next part -- An HTML attachment was scrubbed...
