A mega charger at 1160 kwh or 145x8 could charge a 100KWH electric vehicle like a Model S in about 5 min and 10 seconds. If you had a 100KWH battery in a model 3 you'd improve the range by 25% and if you added a second motor possibly another 11% for 430 miles of range. The 25% increase in energy density is coming. Now the car would have to be wired like the Semi where its as if 8x 145KWH lines and 100KWH batteries have been combined into a single cable and single connector and single station and single vehicle. Now what is interesting is is at 24.8mpg and a flow rate of 10 gallons per minute in the US it would take about 1.44 seconds or about 2 minutes, sometimes considerably slower to fill an equivalent 430 mile take. But given that electrics start out charged every day and there is no equivalent at home- not even if people want at system that would build up compressed natural gas in tanks and transfer it- since there is no equivalent system- the implementation of this system which will likely always have uniform charge rates vice slow sometimes much slower gas pumps will be the last nail the coffin of any claimed advantage for gas cars. The truth is electric cars are already much more convenient than gas cars almost every day of the year. Radically so. And this mega charger will meet electric cars that not only have a lower total cost of ownership but also a lower sticker price and not equal or better range. Further that Trump admin will be gone by then and policies that aim to make up incredibly embarrassing and corrupt lost ground will have hit by then. And its likely that to make this really convenient as that might be a heavy connector and cable for the Semi and to make it safer the car would pull up and the system would engage from underneath the car- not saying this would be the case for the Semi but presumably with self driving semis it will also be an automated system like Tesla's snake charger. This under carriage system is something Tesla has patents for or at least has tried designs. Remember Tesla had the battery swapper system as well. One thing is this might be a bit more than 7 cents a kwh but may not be that much more. Thing is even at 80kwh if you assume you need 3x as much battery in the ground and assume every 3rd charge would be a cycle, across 5K charge cycle life you might need still another 50% bulk discount off retail (80kwh in a couple to few years) to get to 9 cents a kwh just for pack replacements and maybe another 3 cents (or possibly a lot less for the canopy PV provided power.) Maybe 11 kwh- but that might be at cost and not covering real estate etc. But it seems that every charger station will become an automated dealership. You'd probably need 8 foot ball field worth of PV canopy. And even if it recharged 1600 cars a day it wouldn't make more than 20K per day in cash flow of the charging. This is where it just make so much more sense to charge at home. But its also feeds into micro grid.
