And if your owners manual contains * ? * Use of any single 12v accessory drawing more than 20A exceeds low voltage system capacity and will void powertrain warranty. Evidence of such abuse will consist of a blown 20A fuse sealed deep within the high voltage battery case for your protection...

Agreed. That is why touchscreen is only a secondary control. Accelerator and brake are primary. I think people would understand if they could drive an old tractor, or an old car with throttle quadrants. A set and forget hand throttle seems absurd to us that are so accustomed to a throttle...

That is a nice theory on flat ground with traction. Skid steer implies some skidding, not optimum rolling. For that reason, I cant even say my idea is good enough to defend. I haven't put enough thought into it. Sometimes a bit of wheelslip is necessary because none of the wheels have...

If I were to write Tesla, it would be to suggest scriptable low speed control algorithms. So that each of us could write the control algorithm we want for our individual use. Submit the script to Tesla engineers for first round safety evaluation, and schedule a time for Tesla to upload the...

Crissa, I respect your knowledge and contributions. Just wanted to point out that 240V in a home is not 3 phase and it definitely is a "Household Voltage" in the US even though US household convenience outlets are 120V. 3 phase is used for generation, long distance transmission, and often...

Braking a spinning wheel with no traction is not difficult or hard on the brake. It is easier than any normal traction braking which must convert the momentum of the entire vehicle to heat, rather than just the momentum of a single unloaded wheel. A clutch operates with friction in the same...

I consider this a must have feature. I've not seen how it is done by Toyota, but now I will have to test drive theirs to see. I'm reminded of Grandpas tractor. Pick a slow gear. Set your constant ground speed with the hand throttle quadrant, and control steering with left and right dig...

Whatever current is required to actually operate the winch, at least that much current would also be required to hold the winch on with electromagnets. You've suggested a very heavy copper replacement for... bolts. Or brackets. Seriously, the electromagnet wouldnt even pick it up off the...

Ranked worst to best IMO. Air powered winch is intrinsically at a disadvantage because air is compressible. In a positive displacement motor, the stored power can be released catastrophically if something breaks. If you don't use positive displacement, then you have to use high volume fast...

Lithium Titanate Oxide LTO https://chargedevs.com/newswire/xalt-claims-unprecedented-cycle-life-performance-for-its-new-lithium-titanate-cell-technology/

LTO/LFP for the intermediate battery. High C rate charge and discharge, 30,000 cycles, poor volumetric energy density doesn't matter much for an intermediate battery.

The brakes and lights consume power. So unless we also want to do wireless charging and require a trailer battery, it makes more sense to make physical contact. A wireless system is possible, but maybe more useful as a backup redundant system than relied on as a primary safety system. The...

The low friction way to do this would be embedding charge/communicate contacts within the large rubber gaskets of loading docks. Unfortunately, it is the trailers, not the tractor that make contact with the loading dock. Putting Supercharger style chargers near the cab would massively...

I love this idea! One twist to avoid creating a new part. Why can't the charger BE A car ? More likely a Cybertruck filled right to the top of it's GVWR with extra battery capacity in the bed and cab. A FSD electric Jerry can wandering around a Pilot, or a Loves looking for vehicles to top...

Engineering to the rescue. With FSD and height adjustment, all we need is an automatic coupler, like a 5th wheel, to enable dropping and rehooking a trailer without exiting the cab. I imagine the tow mode screen may have buttons for "Decouple trailer, proceed to available charge point" and...

I don't dispute your analysis. I also maintain my assertion that auxiliary batteries will be a thing. Your analysis only treats an aux battery as a range extender. I believe its true value is as a "stay extender". The electric equivalent of carrying Jerry cans. Yes, you can also use it to...

It may not require Tesla. The built in ability to adjust ride height is enough to make underbody swaps easier. As electric pickups become common, someone will inevitably make a universal pack to fit in the bed and emulate a charger. A subpar solution, but still a solution. Once that is done...

I wonder how the cost of steel ramp compares to a one foot addition to the face of your garage and relocating the rollup door into it? Walls aint permanent, but in this case there doesn't even need to be any demolition. The gap is a perfect place to build in cabinets, maybe an overhead hoist...

Having lots of battery power for days at a time off grid could be a back country game changer. Perhaps a smallish battery, always attached, would provide light weight and high ground clearance, but an "auxiliary slice" bolt on undertray battery would satisfy expedition needs and double as a...

I picked dual motor because my critical use case is off road. Given 4wd, lighter is better. Trimotor has heavier battery and motor. I am not power constrained doing constant 8 mph over rocks. 4 motor could be worse due to more weight, or much better due to 4 wheel torque vectoring. Add in 4...
