You can estimate the 'charging MPH' for a 120v 15a outlet. Or any outlet. The max amps is 80% of the nominal. Power: 120v x 15a x 0.8=1.44 kW. You just need to know the pack size (kWh) and (real world) range for that pack (miles). That is enough to let you calculate the Wh/mile. 60 kWh/240 miles

Re: [EVDL] Has Tesla gone too far?

Which models have SAE ports? The only adapter I know of is Chademo. I don't know if that adapter would be disabled in this case. I mention it because I have read that Tesla counts Chademo as a supercharging session in regard to battery usage metrics. There is another controversy that Tesla may be

Re: [EVDL] What to do with used LiOn CALB batteries?

Are these cells still available? How big is each cell physically? I have an inverter charger that can handle lithium...and needs batteries. Any idea on what their capacity looked like when you took them out of the vehicle? Asked differently...how was your range at the end vs when newly installed

Re: [EVDL] EVLN: EV packs optimized 4longevity, Phone Batteries 4co$t

As for electric airplane flight endurance... we have already seen small conventional type aircraft with 1 hour endurance, and experimental type aircraft (100% solar+battery) with multiple day endurance with transpacific and transatlantic flights. On April 5, 2018 5:17:26 PM CDT, EVDL

Re: [EVDL] EVjacker: Stymied by Bolt EV controls> arrested, $20k-bail Austin-TX

That sounds like a plausible scenario. If the car were a Prius Gen 3 put in park, I think the behavior without a key fob is it will stay running but will not allow you to shift out of P. If already in D/drive, the fob is not needed (however the car will warn you) until the car is put back in

Re: [EVDL] Fast Charging... (Flywheel?)

Tesla does load balancing and load limiting at its superchargers. Although most of their stations are rated at 120, 135, or 145 kW, they usually deliver less based on these factors: -utility ordered power limits. Drivers see this when their low SoC cars start out with high kW and in under a

Re: [EVDL] EVLN: GM sez their EVs will be profitable by 2021

I guess that's a good development. Makes one go hmmm when you think about past claims about the GM EV1 (and also EVs in general) being impossible to make profitably. Sunk costs and ongoing R costs can be manageable when you look at them with the right scale. On February 4, 2018 9:19:19 PM

Re: [EVDL] Solar trailer calculation

How about we put solar cells on the road surface and either conductively or inductively transfer the energy to the car? :) No wind problems this way. No large trailers needed either. It would have localized shading by snow and rush hour, though, amongst other issues pointed out elsewhere for

Re: [EVDL] Solar trailer (a 1000-to-1 waste)

Small lightly loaded trailers with little wind resistance can add 50-80 Wh/mile. Taller/heavier trailers can double vehicle energy consumption. On December 29, 2017 2:20:20 PM CST, Bill Dube via EV wrote: >I agree 100%. >Folks forget that it takes significant energy to tow

Re: [EVDL] Solar trailer

Leaf power level demands at 55 mph are easily 4 mi/kWh or 250 Wh/mi (or 13.75 kWh/55 miles at 55 mph). It would be awesome if Leaf energy consumption was as low as you mentioned but most owner experiences indicate otherwise. With your numbers a Leaf could easily do 150 miles. Many owners get

Re: [EVDL] Solar trailer calculation

A solar trailer with a conventional EV is not well suited to sustained highway speed transport. It can however be useful for range extension (if you can charge while driving or use the trailer as a pusher) or for slow charging while camping at non-electric camp sites. Getting 1 kW on a trailer

Re: [EVDL] Solar trailer calculation

If you really want a directly solar powered vehicle, you will want to look at the low profile lightweight solar racers that many university teams put together. These tend to use bicycle-like components. Making it work for a conventional vehicle for sustained highway speeds runs into space,

Re: [EVDL] Combating ICED EV parking spaces

A mix of options would be preferable IMO. L1 outlets in most places, and some L2 stations marked with signs saying 4 hour limits. A notification system that charging is done or that a space is available would be a nice enhancement. One thing is I'm not convinced that providing L1 120v outlets

Re: [EVDL] Towing with a Bolt

A more complex answer is manufacturers promote or don't promote towing abilities as part of market segmentation. In some parts of the world, a vehicle model is tow rated but in other parts the same vehicle isn't rated. Depending on local factors this may either encourage or even force people to

It's a Spaceballs movie reference for the fastest starship speed. Like turning it up to 11 is a reference to the film This Is Spinal Tap. Tesla likes to make certain pop cultural references in their vehicle user interface options for drive motor and fan speed performance settings. On November
