has anyone done any studies once so ever on how many EVs the grid can take? the grid was never designed for such massive power draw it will melt well before you could get anything out of it and i mean even in a northern climate during winter. if toronto went to EVs exclusively the entire power grid would break from the electrical lines heat generation even if the conditions are in the coldest temperatures on record to help the lines cool down. the good news is it is impossible to get i would say more than 20% EVs on the road before the whole scheme comes crashing down so just need to tough out a few winters
California can't even support its electrical needs without this mandate!
california keeps telling people not to charge their cars due to the heat and ac usage.
not hard to figure out the rest of the country will end up worse off looking at them
EV’s get terrible mileage in the cold, any northern state adopting this is retarded. At least millennials is holding off for now. Washington is full retard ahead and Oregon is considering it, which means yes.
Transmission lines are not going to melt because physics. High voltage travels outside the conductor using the "skin effect" which is why high voltage lines are not insulated (as this would actually impede the flow of electrons on the skin of the wire).
Secondly, those wires are directly exposed to the air, and the marginal thermal buildup in the core of the wire (which again is nearly non-existant due to skin effect) gets quickly dissapated.
The issue would be with the oil-cooled transformers that convert the high voltage to lower voltages and vice-versa. This is where "meltdowns" happen. Usually with a bang.
what is the limit to the skin effect? we are talking putting a load completely out of this world as far as the designers are concerned. also i understand the transformers and such would blow first but i was more pointing out the sheer volume of current required to power those vehicles. if the skin effect gets strong enough would the electricity not be forced into the metal since it would be of less resistance?
You are correct, because we are dealing with alternating current, for a breif time of the duty cycle, the voltage Is insufficient to produce the skin effect. It's worthy of note that power=amps X volts so if your line is at 100kv at peak, and skin effect disappears at (guessing) 10kv, then 10% of the duty cycle is subject to 10% of the load. Which works out to about 1% of overall load actually travelling inside the conductor.
Granted there is a failure point, but without going down a math rabbit hole I will hazard a guess that it would take at least a 1000% load increase above normal to reach critical level.
This is just rough math, I'm sure there are published specs out there somewhere on the capacity of HV lines. It's Sunday and digging sounds like work.
My point being; the power producing stations and distribution substations will fail long before the transmission lines become an issue, since they operate at near-capacity routinely and could not even handle a 100% load increase.
most ive seen is posts by people claiming to be electrical engineers, each neighborhood thats connected to the same grid can handle 10 cars at most.
My county has been experiencing more blackouts in certain areas than normal, finally looked up what whats going on as im never affected and it was in the "richer" part of the county which would be driving all the electrics.
It’s about car maker profits, they get an extra 20,000 per ev sold because of mark ups. And good luck reselling your used ev with 50% battery life.
They’re locking you in to buying new only or paying them 15-20 thousand for a new battery if you buy used.
Will they also ban the resale of non-ev vehicles, will you be able to register it or register one you buy out of state?
