EVs will require new battery technology to replace the role of large diesel vehicles.
They will?
So, what about the current Semi trucks in development? Daimler and Tesla are already making working prototypes.
In USA, long distance semis typically expect to travel 1000 - 1200 km / 24 hours. Not all travel is horizontal or above 15 degrees C. The tractor units also provide power for some loads ( refrigeration, temperature control ), as well as the cabs both during travel and mandatory sleeping breaks. Some EV proponents suggest battery rental and/or quick replacement and autonomous vehicles will overcome those issues. However, a 36 tonne vehicle at speed on an Interstate is likely to puree the occupants of any car unfortunate enough to be hit, even if semi has anti-intrusion skirts. As noted above, a Tesla EV is unlikely to be competitive for long distance freight, but may be for urban delivery roles. It's quite possible urban areas will penalise/expel diesel vehicles over next few years, so upfront/operating costs will become irrelevant.
For other situations truckers will be interested if operating costs are lower, but more particularly once load/distance costs are comparable and initial capital cost is similar. Given the battery thermal management/lifetime issues with "high" charge rates ( even on some current EV batteries ), I'd suggest new battery technology will be the breakthrough. However mass/speed/axle damage to roads will have to be repaired from revenue from somewhere, so heavy EVs can no longer expect RUC and taxation holidays.
