I'm guessing you don't only use electricity during daylight and therefore understand that it is not only solar energy from that solar farm that is being delivered to you, no matter what the financial/certificate accounting says.
Most likely if your current panel is limited to 100A, the service wire from the meter to the panel and the wire from the transformer to the meter are both only sized for 100A. If this is the case, it is most likely better to just add a second 100A meter that feeds a new panel with 100A breaker that feeds the vehicle charger. This would be better than ripping into the current service for the house and allows for using a meter that charges one rate during the day and a lower one at night when it is best to charge the vehicle. I went to a meter for my 200A service that charges based on time of day and the savings for charging the car at night were more than offset by paying higher rates during the day on all other electricity uses
, so I would have been better off putting in a second meter and panel.
No need to keep bringing this tired boogeyman back out. EV adoption will not happen overnight, it’ll take 20 years. Plenty of time for us to build out renewables and a resilient grid. We’ll all get to watch it happen, live, I think that’s going to be awesome to see us changing our society for the better.
I bet people were making this same point when electric ranges and electric dryers were popularized.
As any electrician knows, these loads, and electric heating are taken into account when you calculate the service requirements for a home, and for subdivisions. They have been taken into account for decades, whereas electric vehicles were not taken into account when the vast majority of subdivisions were built.
The guy in the video is looking at this totally from the theoretical side, he isn't looking at it from the practical side. His theory is that of course the power companies will sell you more power, but he doesn't address the issue of where all of that extra electricity will come from. It's not like the current plants can just increase production by 30% or more, and you don't just build an electrical plant these days, especially with today's environmental concerns. The same people pushing for electric vehicles are opposing the construction of more plants because of environmental concerns. He looks at the numbers as to what the percentage of actual electricity will be, but he doesn't address how to coordinate all electrical loads, to balance the transmission, to avoid any peak increases. If everyone come home from work and plugs in their vehicles, you create another huge spike in the demand. As for using Norway as an example, they don't have anywhere near the amount of vehicles per capita that we do, and they don't drive the distances that we do. If you look at the numbers, the average Scandinavian drives between 50-60% as ,many miles per year as the average American.
I think you're reading it wrong. There are 2 chargers but they are inside the truck with ER battery. The 80A EVSE that is included with that truck is 80A, and it does need 100A circuit.
Everyone talks about load, but I hadn't heard anyone else bring up the grid implications of harmonic distortion from EVSEs. I wonder if this will be mitigated by the fact that charge initiations are random.
