Technically, Tesla already does this in their cars. There is a mechanical reduction gear.
I agree that many SC locations are inconvenient when towing, but there are plenty of pull-thru or other accessible locations. People tow with the MX and MY currently, and have managed OK.
Racing off the line won't do your range any favors, but towing induces friction and drag, which can be minimized but not avoided.
It depends. Towing around town will be great. Long distance towing of most trailers will require a willingness to spend significantly more time than a ICE truck. If range is cut by half, not only do you have to charge twice as often, you also likely have to charge into the top half of the battery which will be a much slower charging speeds. Having to drop a trailer also adds time. My little utility trailer takes about 5 minutes to hook up and 3-4 minutes to unhook. My pop up trailer took a bit longer and my Dad's camping trailer with a weight distributing hitch took 10-15 minutes to hook up and a bit less to unhook. Doing any of those things in inclement weather is not my idea of a good time. Having to drop a trailer every hour and half to three hours, it will make for a challenging trip. It will be doable, but it is a real consideration. It will be fine for infrequent towing or towing from campground to another campground with the ability to charge overnight, but it really won't be practical for frequent, long distance towing unless the trailer is very aerodynamic.
No perpetual motion, just a reference to a comparable system. The I.C.E. and transmissions of old used gear reduction to keep the engine within the peak RPM range during the different applications. To break the inertia of the vehicle, the gear reduction amplified the torque sacrificing acceleration. Once the inertia had changed to motion the gearing was changed until the desired operating speed allowed for a 1:1 ratio or a fraction:1 overdrive.
I was only aware of the differential between the wheels. Still, the gear that I was suggesting was for breaking the inertia with a "longer lever" to minimize the energy drain during the change of inertia from a dead stop. Tesla has thrilled me with their improvements to the electric motor design. I will honestly be stunned if the Semi or the Cybertruck suffer the same energy losses with this new carbon fiber wrapped motor with the improved design. Rivian, Ford, and Cheby are all WAY behind with the electrics they are using in their vehicles.
There is always energy loss. I bet there is some heat generated in that motor from the regen process!
Would it even be possible to charge with your own panels that have a 12,24V output? I would like that for even at home with a solar carport and without the need for overhead of beefy inverter,charge controller, battery storage needed for traditional charging.
Solar controller would change the voltage to match. At a slight loss, of course. I run my panels at 100v. I have some I can run at 1000v but I only have a half dozen of them and they produce about 4.5v each. Weird surplus stuff is weird ^-^ Was meant to go on the outside of a large solar vehicle in 2009.
