I think EV sales have fallen because all of the "early adopters", who bought an EV for social status, have already filled the pipeline. Now we see 50% of these people regret the purchase. This is nothing new, any product that is purchased to elevate your social status will eventually run out of customers. the vast majority are more responsible consumers and just don't care about impressing anyone. However our government overlords pass "executive orders" to force people to buy 50% EV's by 2025? In the US that's 7 or 8 million cars per year.
When it comes down to it, is it practical/possible?:
According to Electrly, the electric vehicle charging manufacturer.
Each Tesla uses between 0.24 to 0.30 kWh per mile, or about 4,500 kWh over a year for 15,000 miles of driving. Other electric vehicles use more or less, but within a similar range. At 0.30 kWh per mile, that's 90 kWh for 300 miles of driving for the typical week.
The average American household without an in-home EV charging station consumes about 30 kWh per day, or about 10,720 kWh over a year's time. With just one electric vehicle being charged at home, that total increases to about 15,220 kWh. For two-EV households, that total runs up to nearly 20,000 kWh per year (assuming both drivers commute to work). That's nearly double current electricity usage for such families.
...Two home-charged EVs would eat up nearly half the household's total electricity usage – and require thousands of dollars to upgrade the house's electric panel. Today's 50-kva transformers, which cost about $8,000 each, can power about 60 homes; that number drops closer to 40 if each of those homes houses one electric vehicle, closer to 30 with two EVs using home chargers.
For a city with 120,000 homes, which today may require about 2,000 transformers, the addition of 120,000 home-charged electric vehicles means adding 1,000 transformers, about $8 million. But that's just the tip of the iceberg, because distributing 50 to 100% more household electricity requires generating 50 to 100% more electricity.
50-100% more electricity demand for 8 million cars every year? I don't think so.
