- rlkf 8y agoNo need, because it is simply untrue: Electric vehicles can charge on anything from 1-ph 8A 240V, to 3-ph 32A 400V, all of which can easily be provided by common urban household wiring.
- jblow 8y agoNot sure who is downvoting you. I charged my Tesla Roadster on 120v 15A for like 6 years.
- api 8y agoApparently motels are having to crack down on "extension cording" now. Park near your room, crack a window, free fill up...
- greglindahl 8y agoIt’s just a few dollars, maybe the should try letting people pay?
- lostapathy 8y agowhere are you located that household 3 phase is available? Lots of hobby machinists would kill for that but it just isn’t available most places.
- FullyFunctional 8y agoAnnecdata: all the houses I personally know of in the south bay (North California, USA) area have three phase power, and the oldest was built in the 1940es. Charging a Model S from a 110V 20A outlet is very slow and probably not a very useful option (but I have done it on a visit to LA).
- sokoloff 8y agoThree phase (typically 480/3)? Or split-phase 240 VAC (center-tapped, single-phase 240V)? The latter is extremely common/the standard residential service. The former is extremely uncommon residentially.
- kwhitefoot 8y agoOr even less. I tell my Model S to charge at 5A when I am at home (230 V single phase). Gets me 5 km per hour, 60 km from 18:00 to 06:00 which is fine because I average about 20000 km a year which is less than 60 km a day. On road trips I use the superchargers.
- ThrowawayR2 8y agoPerhaps he's referring to the recommendations that Tesla has: "We recommend installing the Wall Connector with a power output to match the on-board charger of the vehicle, typically a 40, 60 or 90 amp circuit breaker." https://www.tesla.com/support/home-charging-installation#wall-connector https://www.tesla.com/support/home-charging-installation#wal... For comparison, the average home circuit is rated for 15 amps.
- jblow 8y agoLast I checked, most homes in the USA had 220v 30A dryer outlets.
- WillPostForFood 8y agoOur house has a 30A dryer outlet on the second floor. The house is maxed out on a 100A main line. To get another 40A or 50A breaker permitted, and installed would mean new main line, new meter, new main breaker, new breaker box. Bids have come in between $7,000 to $9,000. New homes with 200A service will mostly be ok, but older homes are often underserved electrically.
- thinkcontext 8y agoI had my power upgraded from 100A to 200A for $1800 in DC. Do you have to dig?
- sfifs 8y agoSure here https://www.tesla.com/support/home-charging-installation#outlets-adapters https://www.tesla.com/support/home-charging-installation#out... Most home electricity installations have circuit breakers @ 15 Amps where I live. Wiring typically rated to a max 20 Amps draw before overheating. At a below 15 Amps current draw levels, you'll required an inordinate number of hours of charging for getting mileage on the battery and it's just not practical.
- greglindahl 8y agoMost homes have electric stoves and dryers.
- kwhitefoot 8y agoHow many km do you drive in a year? My 20k km is about 55 km per day which is easily supplied by 5A 230 V to my Tesla S in 12 hours, say from 18:00 to 06:00.
- davidgould 8y agoWhen we first got our electric car we used a cord strung out the window, 12 amps at 120 volts. Not a problem, plug in when you get home, unless you need more than 60 miles this will be fine.
