P.S. The 53 kWh figure you give for the Tesla Roadster didn't look right to me. I found THIS PDF document from 2007 which gives the 53 kWh figure, but then THIS PAGE, which appears to be more current, gives a figure of 56 kWh, which is more in line with the wh/mi vs speed and range vs speed graphs that I copied from somewhere a while back. I don't remember where I got them. Probably from the Tesla Club chat board.
Charging time pretty much comes down to power delivered, Wh/mile used, and distance driven. I think most EVs get around 3 to 4 miles per kWh, though that figure would be a nice one to include in the chart. Many EVs (probably all the new ones) can be charged at different rates depending on the service available. So charging time is mostly a function of how far you drove (or the car's range if you want charge time from empty to full) and the power delivered by your EVSE. I think the Leaf can charge at either 1.8 kW or 3.3 kW.* The Tesla Roadster can charge at any rate from 18.8 kW (with the HP connector) down to a trickle, since connectors are available for every level of electrical service, and the current can be limited from the touch screen. So what we'd really like to see on the chart is charging rate and Wh/mile Edit: *I don't know the rate for the 440-v. fast charger. Not all Leafs are equipped with the equipment to use those.
hey, evnow, could you update your chart when you have a chance. Tesla has posted specs details here: Model S Options and Pricing | Tesla Motors You have to click the "show more specs" button to get the drop down below the image of the car with exterior measurements, but then it shows interior dimensions and lots of other info that will fill out your chart. You probably need to list the Model S at least 4 times (40kWh, 60kWh, 85kWh, and 85kWh performance/sport) since the range, 0-60 times, even the inverters and such differ. Plus you'll need something for showing with the 10kW charger and the 20kW charger I think.
Thx for the pointer. I'll be listing only the lowest model (the one corresponding to the price I list) - like all other cars. Later I'll move to range of MSRP and other spec items as well. Multiple models become unwieldy.
As you wish, a comprehensive list would be great to have--maybe on Google or something? Esp. when there are such dramatic differences b/w the models. Supercharging available only in 300mi (maybe 230 mile) is a big deal to many buyers.
I knew that. What I don't know is how many kW the 440 v. charger delivers. And of course it will be a long time before fast chargers are available outside major corridors. I don't expect to see them in my lifetime on the secondary roads I take on my way up to Canada, the only road trips I take anymore. I presume you mean super-fast charging? "Supercharging" is I think normally used to refer to a means of getting more power from an ICE.
Supercharging is the term Tesla is using for it's planned series of charging stations--it's supposed to charge at a rate of 160 miles in 30 minutes. Look at the very bottom of the Options Page: Model S Options and Pricing | Tesla Motors
Thanks, Evan. I think that "supercharger" is a poor choice of names, due to the existing meaning of the term. That aside, I would buy the Model S and sell my Prius if there were Superchargers on all the routes I take up to and within Canada. It would not be as convenient as the Prius, because of the enforced half-hour stop after 3 hours of driving. With the Prius I stop for 5 minutes two or three times in a seven-hour drive (the time to my two most frequent destinations). And because of the risk of additional delays if the charger is in use. But I'd accept that in order to go all electric. However, I doubt that any of the small B.C. and Alberta towns that I go through on my way to my hiking destinations will have supercharge stations in this decade. It's great that they are putting them in where they'll get more use, though, to make the car more practical for people in cities who travel the major corridors.
Miles/kW would seem to make a little more sense, to me. though that should be easy for one to figure out on their own. It did prompt me to check the numbers for the Tesla 160mi/40kW = 4.0kW/mi 230/60kW = 3.8kW/mi 300/85kW - 3.5kW/mi 320 (performance)/85kW = 3.8kW/mi (integrates special aero rims and air suspension which lowers the vehicle for improved aerodynamics)
Evan, you've got your units wrong and your fractions upside down. The first line should read: 160mi/40kWh = 4 miles/kWh Etc.
1 km = 0.621371192 mi 1 mi = 1.609344 km 160mi/40kWh = 4.00 mi/kWh = 0.250 kWh/mi = 0.155 kWh/km 230mi/60kWh = 3.83 mi/kWh = 0.261 kWh/mi = 0.162 kWh/km 300mi/85kWh = 3.53 mi/kWh = 0.283 kWh/mi = 0.176 kWh/km 320mi/85kWh = 3.76 mi/kWh = 0.266 kWh/mi = 0.165 kWh/km
thats what i was looking for now you can see what car ( if you do it like this ) is the most eff. ( read te lowist watts per mile/km ) and its al about saving energy
