Electric trucks are a hot topic these days. Elon Musk says the Tesla Semi will be shown publicly on October 26. It will have a range of 200 to 300 miles, according to reports. Musk says interest from the trucking industry is so strong, most company executives only ask how many can they get and how soon can they get them. Cummins announced earlier this month that it also is hard at work on electric trucks for hauling freight. Its focus is on Class 7 drayage trucks with a range of 100 miles.
Just as with electric cars, range and recharging times are critical considerations. Tesla has recently filed for a patent on a battery swapping system, which many people think is intended for the Tesla Semi. (It might be, but then again it might not be.) The thinking is that after 200 to 300 miles of driving, the depleted battery could be swapped out for fully charges unit while the driver grabs a cup of high octane coffee prior to heading out on the next leg of a journey. Cummins says its 145 kWh battery can be recharged in only an hour. Better make that an extra large coffee, in that case.
