Prime destined to be doa?

check my math, but if 10kW is ¼ of typical home service, then that'd mean typical homes have 40kW's available. Most homes prior to early 1980's didn't even have 100 amp service. 100amps x 240v is only 24kW's. No?
.

 

That also depends on where you are. 200 A service isn't uncommon in all-electric homes.

But, 20 kW home charging is a thing, with Tesla's products, right now, with dual chargers and a HPWC.

 

yes - on newer residential - but the older stuff is still the Lion's share of panels;

It's likely Toyota is reluctant to even move on to 6kW charging - simply because some still have screw in fuses. Out Montana home still had some of its knob & tube wiring. The lawyers would want to assure Toyota isn't going to be the deep pockets on nuisance residential electrical fire litigation.
.

 

I don't see the need to go much above 8 KW charging at home. For a Model S85, that is about 25 miles of range per hour. I very rarely deplete my battery that much during the day. But I'm not using my car for commercial purposes - but you still don't want to get down to under 50 miles of range (or at least I don't) and that means that 220 mile of range need to be added back and that would take 9 hrs at 8 KW.

As for the Superchargers. When my battery is low (10% range/energy left), the car will take 380 V at nearly 300 A. As the battery starts to get closer to full, the Voltage creeps up to 400 V and the current drops down gradually to 100 A. At that point it is taking about a minute for each additional mile of range added and that's when I leave the supercharger assuming I have enough charge to get home or get to the next charger. The supercharger spoils you - 60 miles of range per hour is too slow to wait for.

 

what is the calculation to get to 8kw charging?

 

220V * 40 A ~ 8 KW

 

thanks! that's pretty reasonable for modern home electrics.

 

Yes, from a 50A breaker on the panel, the car will pull 40A. I think the 80% of rated capacity is for safety / overhead so you don't trip the breaker.

 

The math is 8,000 watts (8 kW) \ 240 volts = 33 amps.

US voltage is 240v.

You can calculate the amp draw for any kW charging circuit by taking the number of watts (multiply the number of kW by 1000) and dividing it by voltage (120 or 240v in the US).

 

I'm not reading through 38 pages to see if someone else commented on this, so if it's already been said, oh well.

It's "buenas noches". With an "a".

 

when this thread started, i thought prime would do fairly well, but now, i'm starting to wonder. the controversy seems unprecedented.

 

Well if you assume the only people that were going to buy the Prime were those on PriusChat, then I'd agree with you. However, since it's being introduced in Japan, Europe and the (entire) US and maybe Canada at the same time, then no, we have no way to know if it's going to be DOA. Is it a great daily driver for those of us in the north and northeast? Yes, particularly if you have a garage. The best thing a Toyota salesman can tell somebody from the north and northeast is you can preheat the car while its in the garage with the door shut. Is it a great second car? Absolutely. Is it going to haul everything you are ever going to want to haul? No. That's what my brother-in-law's truck is for. Or a rental. Are you going to haul everybody you want for the next trip. No. That's what my sister's minivan is for.


Unsupervised!

 

Looks like cheap gas is taking its toll on the regular Prius. This may not bode well for the Prime.
We will just have to wait 12 mos to see who puts their money in the game.

 

I still hinge USA Prime success on availability of more CA green HOV stickers.

There is conflicting info, but apparently Ca. Senate Bill 838 passed and is on Gov Brown's desk, and it allows more green HOV stickers, assuming the Gov signs SB 838 without deleting that provision (which he could in theory). So we shall wait for Gov's signature or lack thereof....

 

brown may veto due to pressure from prospective & present day EV manufacturers GM (Spark), VW (E-tron), Tesla (3models), Hyundai, Nissan Et Al, for the bill deliberately leaving off the very cleanest transportation, bev's.
As far as Lanes being overcrowded, the real issue is extremely poor HOV enforcement as on any given day/evening - one can typically see multiple car's drivers going solo - even during a 6 or 8 mile stretch - taking their chances on the measly $300ish fine. Bump it up! .... start filling the state's coffers with cheater $$. There's a heck of a lot more cheaters in the HOV lanes then there are clean cars.
.

 

Well, the Assembly Bill 1924 failed due to shortcomings re: BEV, and Plug in America objections.

But what passed is a Senate Bill 838.
The Senate Bill simply lifts the green HOV cap and presumably defers more thorough reform of the HOV incentive system until the next session. I have not heard that Plug in America objects to SB838, but who knows what is going on behind the scenes. My "thinking" tells me Toyota, GM, FORD, etc have probably been promised more green HOV stickers for now.

 

if the only reason plug ins sell, is because of hov stickers? the king is dead, long live the king.

 

...these are not my words (but they could be if I only knew how to write):

In the world of electric vehicle sales, a surprising amount of importance falls on carpool lane access in California. This is due to the fact that 50% of the entire nation’s plug-in vehicle sales occur there, with one extra large incentive being access to green and white clean air vehicle stickers which allow them to drive in the carpool lane regardless of passengers.

 

They do also get one of the highest state rebates too.

 

that's the rationale that most will throw out, and it's certainly the most weighty, most likely. But in reality it's kind of like All or Nothing thinking. It really discounts the reasons such as saving gas money (all be at less during low prices) , envirinmentally conscious, technogeekyness, buyers awareness of plug-in longevity, etc.
