Electric vehicles need LOTS of integrated circuit chips, already in such short supply that there are assembly lines halted for want of such computed chips, even for “fossil-fuel” powered vehicles.

And there are any number of energy distribution problems with the electric vehicles, not the least of which is a power generation and distribution grid that will be wholly inadequate in a span of less than a decade from now.

While using electricity to power a wheeled vehicle is perfectly good engineering, the means of getting this electric generation power to the vehicle means that an uncommonly great reliance has to be on some kind of storage battery, that needs to be recharged to provide for reuse.

Batteries have some HUGE limitations, in that recharge times are always much more that discharge times, that is, two hours run time probably needs 6-12 hour recharge time, depending of the facilities used, because only so much power can be delivered to the battery while charging without causing great problems with excessive heat and resulting damage to all components of the system.

Also, batteries are either very heavy, or very expensive to construct, or both. And means of disposal of spent batteries can be highly hazardous, or the materials difficult to recycle.

Therefore, “on-board” electricity generation systems, which have yet to be invented or perfected, would be the practical path to widespread application of electric vehicles. Perhaps using electric power to MAKE hydrogen from quantities of brackish or sewage water, collecting this hydrogen, and putting it into tanks that can be quickly swapped out at a fueling station, much like a propane tank, and run the vehicle with fuel cells. Or a small thermonuclear pile, making a tiny heat generation plant that is converted into electricity through a closed turbine system driven by steam or other heat exchange medium, producing electric power on the road. Of course, when the vehicle ISN’T running, there has to be some way either to throw all the generating power back into the grid, or throttle the output of the thermonuclear power in a predictable manner.

“Batteries have some HUGE limitations, in that recharge times are always much more that discharge times, “

Tesla can charge 200 miles range in 15 minutes. That is 3 hours of operation in 15 minutes.

That weight also lowers the center of gravity improving road handling.

Electric motors have superior torque, adequate for the heavier weight.

EV’s recover 70% of the energy required to accelerate that extra weight.

“means that an uncommonly great reliance has to be on some kind of storage battery, that needs to be recharged to provide for reuse.”

Compared to the ICE car that has an uncommonly great reliance on a gas tank.

Source, please.
