Tesla revealed the 'Semi' electric truck earlier this month, promising 400 miles (644km) of charge in just 30 minutes through a new "mega charger" to be manufactured by the company.
In a report published by FT.com, one of Europe's leading energy consultancies has predicted that Tesla's electric haulage truck will need the same energy as up to 4,000 homes to recharge.
John Feddersen, chief executive of Aurora Energy Research, said the energy required for the mega charger to charge a battery in that amount of time would be 1,600 kilowatts.
The amount of energy required to recharge the Tesla truck translates to powering 3,000-4,000 "average" houses, Fedderson added.
While Tesla has installed superchargers for its electric cars, the scope of megachargers by Tesla for haulage trucks is still quite challenging. Tesla has not revealed when it will start offering the network of megachargers despite confirming that the Tesla Semi will be rolled out from 2019.
