How long does it take the new Tesla semi truck to charge?
According to Tesla, an electric semi truck's projected range at 82,000 pounds (the company claims federal laws allow EV trucks to weigh up to 2,000 pounds) is 500 miles.
The precise battery capacity has never been disclosed,
but we do know that there will be two versions, one with a 300-mile range and the other with a 500-mile range.
Tesla claims that the Tesla EV trucks would consume less than 2 kWh of energy each mile.
According to Tesla, the energy consumption of its semi-electric trucks is under 2 kWh/mile,
which is roughly eight Model 3s using typical energy.
Tesla has not specified the size of the battery, although the company has previously stated
that it is feasible to charge the Semi's new one megawatt charger (1,000 kW) to 70% capacity in about 30 minutes.
Elon Musk, the CEO of Tesla, stated that the electric vehicle will only use solar energy and that it will cost $1.26 per mile,
as opposed to $1.51 for a diesel truck. When charged at the megacharger, which Tesla would make sure is priced at 7 US cents per kilowatt-hour, Elon Musk,
the CEO of Tesla, stated the Tesla Semi will be $20 per kilometre (12 US cents per mile) less expensive to operate than a diesel truck (in the US).
