So if the price of power to the charger is $ 0.20 per kwhr, the price of power for 50 kwhr would be $10. I guess he’ll have to charge quite a bit more to make a profit. 

The problem is that "off peak" moves if you shift load. Enough EV charging could create a new peak, for which rates would then rise.Compare to how much power our home can handle vs use at any instance, we will not see everyone turn on their heater at the same second and set them to the same temperature. What I think will happen, is that there is enough overbuild in the local grid to handle the extra load, and with smart meter and time of use rate, we will see prices shift some of the load around and industrial / commercial load will get shift to save money and conserve power at different time of the day.
If they can handle summer AC load they can handle EV charging during off peak, and people will charge during off peak to get a discount.
300 kW means 300 kWh per 60 minutes, or 5 kWh per minute, or a kWh every 12 seconds. So 50 kWh in 10 minutes.
The screen on the charger says the last car was charged 28 kWh in 40 minutes, which is a much more modest rate of about 45 kW.
Just guessing, a house would have about 15 kW of grid capacity planned for it, so one of these 300 kW hyperchargers would require the grid infrastructure of 20 houses.
That 300 kW charger bills at the higher of $0.60/kWh or $0.35/min so the summary on the screen would have translated to $17 or $14, hence the bill was $17.So if the price of power to the charger is $ 0.20 per kwhr, the price of power for 50 kwhr would be $10. I guess he’ll have to charge quite a bit more to make a profit.![]()
In the end driving an EV only consumes a certain amount of energy per mile. Having higher charging capacity or more chargers available doesn't alter that.... One fast charger could use more power than 100 houses(not counting home charging)...
Yes, there are idle fees. Otherwise people would use them as parking spots. This is true at employee subsidized charging all over Silicon Valley.I could see that being profitable.
Ultimately the price ought to be simplified to a single number that can be put on a sign, so consumers can shop by price. Of course it's better for business when consumers don't shop by price.
Does the per-minute cost mean that you have to come back and unplug your car right when it is full to stop the per-minute?
Ideally, yes, however almost all our (NZ) national charging infrastructure is managed and mostly owned by only one private company, thankfully one with a conscience. Certainly in the long term competition will be essential.Ultimately the price ought to be simplified to a single number that can be put on a sign, so consumers can shop by price.

None of our CCS/Chademo (meaning non-Tesla) chargers have an idle fee but I expect that will eventually change. However our Tesla Superchargers do at $1/min, or $2/min if the site is fully utilised. Tesla's energy charges are 50 to 81 cents/kWh, they vary by location.Does the per-minute cost mean that you have to come back and unplug your car right when it is full to stop the per-minute?
That's the bottom line. We are seeing condo complexes looking into chargers, due to owner demand.I worked for Mobil oil and I'm perplexed by this entire thing. I cannot undersrtand how reselling electrical power will make a company more money than pumping millions of gallons of free oil per day, refining it into 300 different and often expensive products and selling those products to every company and person on Earth. The fact is, just so many people are going to charge outside of the home.
Yes, but that is not what BP is saying. Their real profit is in drilling etc. Gas stations are not as big of priority as other businesses. So perhaps chargers can make more money than gas stations.I worked for Mobil oil and I'm perplexed by this entire thing.

Or for people unable to charge at their homes.As @Cujet pointed out, the issue is demand. If people drive less than 40 miles per day, they are not using outside charging stations.
ICE owners driving the same are fueling up once a week at the gas station.
Fast forward 5 to 10 years from now...
The need for these charging stations will be primarily along freeways for the longer trips.
You would be surprised at how many use public charging stations who drive less than 40 miles per day. For one thing if you have a battery with 250 range you may want to charge every day for an hour just to keep the battery near the middle or lower. I see it all the time, in fact it is hard to get a spot where there is free charging. Same guys are in it every single day if they are lucky.As @Cujet pointed out, the issue is demand.

UD, that's why I said 5 to 10 years from now. The demand is already driving multi-home complexes to investigate charger installation.Or for people unable to charge at their homes.

Of course Silicon Valley is a tech bubble, but it is also a leader for the rest of the country. It's starting.
I am curious as to what China does.
Elon started building his network as he introduced cars. It is certainly possible he has someting in the works.
The utilisation can be judged using plugshare.com since the status of many stations is publically available in real time.I wonder what kind of profit 30K charging stalls can generate?
