Nonsense. Most older homes have already been upgraded to 200 amp service panels so they can handle modern conveniences like electric clothes dryers and air conditioning.
The real reason car manufacturers are scaling back EV production is we're in a massive recession and on the brink of global war with Russia.
More nonsense. EV's have no trouble climbing hills and the power loss of the "transmission" is much less than ICE vehicles.
The limiting factor is battery size. If an EV has a small battery with limited range then that will also limit the amount of power reaching the motor. If you engineer a perfect storm of bad conditions for example driving to the Yukon with a heavy trailer in sub zero temperatures then your EV will not perform as well as it would on a nice day.
A lot of two bedroom homes only have 100A panels. There are a lot of homes still running on 1970 and less wiring on 100A panels. elder farms home with even less. These homes did not have the power loads we have today. Like I said before , your clients have modern homes in the suburbs. 200A became the minimum standard in the late 70s or early 1980s. Bear in mind if you have a 200A panel, you are not suppose to draw over 160A continous. You add up a washer, a dryer, a stove, a microwave, hot water heater, and a air conditioner/heat pump, and other incidental loads running during your dinner, you might find you are on the border or exceeded safety requirements.
from what I know about the EV charging systems the 120V units for Telsa requires a 20A circuit. And this circuit, it takes 4 days to fully recharge. Telsa's data. Telsa shows their 240A chargers drawing up to 80A running on 240V - thats takes a 100A rated 240V circuit. If you buy the biggest charger (80A), it will take 6 hours to recharge. Smallest charger is 20A and Telsa shows 30 hours to recharge.
Want a super charger ? 480V at 300A or 240V at 600A, not your normal home circuit. 40 minutes to recharge.
Lets talk about the city. Are they going to tear up the sidewalks and install chargers for the folks that park cars on streets ? Lot of places like this. How about high density places like parking buildings. Believe they will have to add electrical capacity.
The batteries are the problems. What good is a powerful electrical engine if you can't power it?. Don't bury you head in the sand.
I have been behind EVs were we have 13 degree grades. They hold everybody up for miles...
I'm not going to argue this anymore. We can agree to disagree.
