The CEO of Ford admits to purchasing and daily driving the Chinese EV Xiaomi Speed Ultra 7. He imported for his personal use; and he doesn't want to give up it. Must be nice. (finance.yahoo.com)

I agree. And for those that need a vehicle because they live in the middle of fucking nowhere, EVs are a good middle ground.

I get why construction teams don't use them, since one bad charging connection overnight can bring the entire project to a grinding halt for the next day. Meanwhile if Joe forgot to gas up the backhoe before leaving last night it's only a minor delay while someone goes to do Joe's job.

For anyone and everyone else, EVs are generally viable and in many cases, a much better choice than the alternatives.

For anyone in a city, the fact that you feel you need a car, is the problem.

    Construction/trades are actually a pretty good use case for the EV pickups. As you say, it is a hard stop if they’re not charged, but a short trip carrying tools and people to the job site and subsequent short trips to the supply house are usually easily within reach. It’s the backhoe with 8 hrs of runtime that’s difficult to replace, and wiring them to the grid is a bad idea because they’re inherently cable-seeking. (In seriousness, I think it’s an idea that can be explored but is largely impractical. What construction site has a 200kw grid connection, what size cables are you using that won’t be “adjusted” by the local tweakers, and how do you handle an accident.)

    All good points, and I especially agree about the cable seeking part (working in IT we refer to it as a fiber seeking backhoe, but the same principle applies).

    As for a grid connection, I'm not sure 200kW is strictly required for just a backhoe, but if we're taking the example to a practical place of EVs running the show rather than diesel, all of the construction equipment charging at once is probably going to need 200kW combined to charge, if not more; so the point stands IMO.

    Just as a mental exercise, thinking about the backhoe specifically, getting it connected to a grid, IMO, would basically require that a temporary structure be erected over where it will be operating to provide a line to the unit from above, since it may need to turn any/all direction(s). Which assumes that it's working in a location where there is free space over the work area, and any time the unit is moved the grid attachment scaffolding would need to go with it.

    I imagine the power line would run up one of the legs of the scaffold, to a mid point, then there would be a tensioner on an "extension cable" (of sorts), to the backhoe to avoid any slack that could be caught up in the normal operation of the vehicle.

    Needless to say, this is a lot more work and bluntly, wildly impractical for construction use.

    I'm just saying it could work, but there's no way in hell any construction company is jumping through the hoops to make it work, even if a backhoe company built one, which they won't because it's wildly impractical and nobody would ever buy one.

    Thinking economically about it, there's probably 10,000 cars being driven for every construction vehicle in use, so it's not exactly a large target to focus on. IMO, one of the bigger areas where we should be trying to save emissions is in marine travel. Specifically large cargo ships. With commerce being as international as it is, and only increasing in demand, those ships are running almost 24/7, usually on diesel or another fossil fuel.

    Solving that problem would probably have a much larger impact than trying to get construction crews off of using diesel in their equipment.

    Just a thought.

    The 200kw is really more about peak output but peak isn’t constant, so a small battery pack would service that part.

    wildly impractical for construction use.

    It could work for some types of long term projects. But probably not worth the development costs.

    Marine is a significant opportunity. Bunker oil is nasty to burn!
