I'm I really getting 1364MPG?
 

So I was looking around on electricitymap.org and the electricity grid here in Sweden was releasing around 36gCO2/kWh produced.

And I'm getting about 9km/kWh as far as I can tell. (The instrumentation is a bit lacking) That means only 4gCO2/km or 1364MPG! :D

Of course your power plants don't burn gasoline, but still an awesome number!
Congratulations,

And this is why we need more EVs on the roads. Raise the MPGe and lower the CO2 emissions along as many points of the supply chain as possible.

I just wish range was better.

Rajge is currently adequate for most purposes. Charging needs to get faster. If it takes you <10 minutes to fully recharge from numerous places on a trip, you're at gasoline capabilities. 10 minutes is a rest stop visit for me.

It's all about watts/hour. You can only put so many amps through a wire so you have to keep increasing the volts. It starts to get to be dangerous. No way you can recharge the even bigger batteries on 480 volt superchargers even faster than they do now. So if you want 5 times the current speed on a battery twice as big as a current battery, you start talking about Joe Blow snapping together a cable that has more like 4800 volts. Then lined up like a gas station 10 "pumps" so a 48000 volt feed, just for the equivalent of one average corner station. It's like adding a steel refinery to every neighborhood.

You dont need the 48 kv feed. That's for powering cities via substations. 1.2kv is available and at a measly 30 amps is (suprise) 36 kw. 60 amps is double that. This is typical large manufacturing factory power levels, but it does require a substation close by. Joe Average shouldn't be playing around with these power levels without some serious safety protocols that he can't shortcut.

But you would need need much more than 72kw to refill a 300kw battery in 10 mins like you can refill a gas tank with that kind of range in 10 mins. Obviously you would need 300kw in just 10 mins which would be 6 times 300 or 1800kw or a 30kv feed at 60 amps. That's just to do one car but if 10 wanted to refill at the same time, as is common at the petrol station you would need 10 times the volts or 10 times the amps either way too much.

Bigger batteries for more range just means long charging times and in a home setting that could mean days not hours and certainly never minutes.

Viola! you just described why recharge has to change to be comparable to fuel.
The next question is what do you with all that battery heat?

A ten minute refuel is probably unobtanium, so different schemas are necessary. Do you REALLY need to drive from Reno to Seattle on one tank/charge?

No I think huge batteries are a bad idea, but that's the trend, that's what sells. Also putting them in real full size 4wd trucks and SUVs us going to be what it takes to get people out of real gas full size trucks and SUVs. I like the Model X but it's not realistically a 3 row SUV, putting 3 rows in any other Tesla is just a waste of maybe otherwise useful hatchback space. Then as far as range you should be able to at least drive 4 hours straight at 70 mph and then get a short 10-20 min recharge. So that 280 mile range should fall in the 20-80% battery capacity.

MPG
 

In the USA, Regular Unleaded, 10% Ethanol, Reformulated gasoline contains 111, 836 Btu / gallon.
A kilowatt-hour = 3412 Btu.
Giving 32.7772- kWh/ gallon
Your 9-km would be 5.592 - miles / 1,000-Watts, or 178.816 Wh /mile.
I'd need to know your velocity in order to give you a MPG.
