To get a sense of the scale and throughput difference in the infrastructure and technology all we have to do is compare gas station statistics vs. charger stations.
There are about 10,000 gas stations in CA and approximately 1,200 Tesla Supercharger stations in the State.
How long does it take to load-up with a 300 mile range with each technology?
Gasoline, about 5 minutes plus another 5 for the transaction (in and out of the car, paying, etc.)
Tesla (can't do 300 miles but let's just call it topping off), about 80 minutes.
Round numbers:
One gas pump can service approximately 144 vehicles per day.
A Supercharger station charger can do about 18 vehicles per day.
That's basically a factor of 10 difference in throughput. Which, during an emergency or holiday/high-travel-volume event is an absolutely MASSIVE difference.
If we assume 10 gas pumps per station and 10 chargers per Tesla location, the total number of vehicles that can be serviced per day in CA is:
Gas stations: 14 million cars per day
Tesla Superchargers: 216,000 vehicles per day
That, right there, is the difference. The infrastructure isn't anywhere near the ubiquity, availability and performance of the IC engine fuel delivery infrastructure.
We can deny this all we want, but reality hits you hard when things deviate from the ideal.
I mean, the army could go down neighborhoods distributing gasoline to people in worse case scenarios. What are they going to do, park massive diesel generators to charge electric cars? Not going to happen.
My educated guess is that we need a better energy delivery mechanism for electric cars. It has to be something you can pump into a tank in 5 or 10 minutes. Pushing electrons into a battery, without fundamental advances in technology, seems like a bad long term plan.
I mean, Tesla doesn't have that many cars in the Southern California region in comparison to conventional vehicles and their Supercharger network flops with holiday travel and becomes a liability during emergencies. That's not a good long-term plan. The cost of adding a million EV's will require an absolutely massive investment in the charging network. Ten million and the numbers become almost unthinkable. A hundred million feels like a joke to even consider.
