7 Kwh in an electric equipped with a 7.2kwh charger on board is a 1 hour recharge. If it's a 365V battery and truly can take 7 Kwh at a 35 to 40 kwh DCFC rate, you are looking at about 9 or 10 minutes to add 7 kwh in a proper fast charge equipped 24 kwh rated battery.LenSatic wrote:

I am probably missing the obvious but why would a Prius not do well with an eclipse. Do priuses have some kind of aversion to temporary darkness lasting 3 minutes??? And why would one deliver electricity to a Prius. They run on gas. Do you mean they somehow broke down?
Not sure how it relates to a prius but yes there are some triple A vehicles in the LA basin that can provide a 7 KWH DCFC charge to a stranded electric vehicle. Enough to get to a charge station etc.
Sounds about right. A fast charge stop for us gets us from 20 percent to 80 percent in about 20 minutes. Ours is a 30KWH battery.
Electric vehicle sales penetration will be close to 5 percent in Southern California this year and probably double that next year so there is probably a need for tow companies to adapt this capability sooner than later. Having said that, EV's have gauges or displays to indicate their state of charge. It should not become a common thing to run out of power. It's all about planning.John & Angela wrote:

It had nothing to do with the eclipse it was the slow moving traffic that caused our problem after the eclipse. Ten MPH was fast! It was one lane of bumper-to-bumper automobiles for 72 miles. Like I said, I don't know why they pulled off, only that they did. Do they have to maintain a certain speed to switch to the battery?

Hmmm. Not a prius expert but they are essentially a Hybrid. They are primarily gas vehicles with a short electric only range. Maybe 45 miles. Like I say, not a Prius expert. But they have normal size gas tanks so I would suspect ranges of 500 to 600 km.
A pure Electric EV would do very well in those type of situations. At slow speeds an EV can easily get double its rated range. They can sit for hours in traffic with the AC on using very little power. However, the infrastructure is not evenly spread around the continent yet so hard to say what charging options would have been available in that area though.John & Angela wrote:

With a few (6 or 10) L2 stations for free most businesses would not even notice a blip in the total electric bill. Although it would most likely bring in more sales.
I wonder how long it will be before the Free Enterprize System prices electricity from EV recharging stations such that it costs about as much (or more, years into the future) per mile - based on some average and ever-changing pricing formula - to drive them as an equivalent size gasoline or diesel powered vehicle?
I can't imagine free or dirt cheap EV "refueling" lasting too long into the future. Cheap refueling electricity is probably viewed as a "loss leader product" right now to get us into the EV buying mood.
Actually by the time the commercial equipment is installed to monitor and collect a fee the cost is probably higher than giving out the electric for free with an open un-metered connection.
Yep. It's already a proven loss leader marketing tool. EV drivers will shop or eat at restaurants where they can hook up and charge for free. It's the coupon cutting crowd that it works for. Ever clip a two for one entree coupon for a restaurant? But it's cheaper for the restaurant to give away a buck worth of power than making a 5 dollar coupon. Lots of people live in Condos where there is no facility to charge an EV. These folks will frequent malls, shopping areas and restaurants where they can charge while going about their daily routine. We do ninety percent of our charging at home but admit that we tend to gravitate to establishments that have charging infrastructure.
Re-rising electricity costs. Maybe. But utility companies also have to compete with private homeowners and business owners capability to make their own power. Solar power and storage products like the Tesla wall will keep the Utility companies "honest". If utility companies charge stupid rates people will just go off grid...or at least those who can depending where they live etc. The average EV usage in North America uses about the equivalent of a residential water heater for a family of 4 so it doesn't take a ton of solar and storage to deal with the energy needs of an EV. I think the next ten years will see a fair amount of growth in home storage. Should be interesting.pnichols wrote:
I'm not a fan of individual solar setups at personal residences. I'd rather see the grid still supplying the bulk of personal residence power - including EV charging - but with grid power becoming cheaper and cheaper as large solar and wind farms feeding the grid come on line more and more across the U.S.. IMHO, that's the most efficient way for non-fossil power to benefit the masses and Planet Earth -> use the huge grid system that is already in place but feed it with solar and wind generated energy. (My thouughts on solar and wind sourcing of power are assuming that nuclear fusion power is still a long way off, or impossible.)
My payback will be five years. That is a 20 percent return on my money. My best investment in quite a while.
I like the idea of distributed solar. Less need for transmission lines into the city or remote areas. My house was built with a 200 amp panel and all the infrastructure to support that power level. Add a battery to the mix and I could easily do fine with 20 or 30 amp service.
That would be 85 to 90 percent reduction in the infrastructure needed for my home. Or to say it another way that 200 amp service could support 8 to 10 homes instead of one. This would reduce grid costs that are currently more than half the cost of power in Southern California.- It's a San Diego based company. It depends on the size of the battery etc. Not cheap though. Anywhere from 25000 to 45000. It can be used as well to supplement the house needs etc. We own a town house so not going to work for us but otherwise would have been neat.

"Cool pics. Thanks for sharing. Are you completely off grid?"
Yep, 100%. That doesn't mean we are self-sufficient, though. Propane is delivered once or twice a year. Basically our home is a scaled-up RV.
About $40,000. Self contained EVSE charger for electric vehicles.
I know that the question wasn't for me but, as a comparison, our whole house system was $45,000. (That was the cost before our tax incentives. I'm not sure what our real cost was. We didn't owe any Fed Income tax for 5 years and, since everything was purchased in AZ, there was no sales tax either.)
