Three separate 3kW charger units are fitted to the battery pack and it
takes 20 hours to recharge the huge battery. Using a three-phase electrical
supply it takes eight hours for a full charge.
Hmm. 90 amps on three-phase. What people often forget is that the
National Grid is on record as saying that these kinds of additional
power draw are unsustainable for anything more than a fraction of
vehicles.
(And it's not just the main grid, but also the local supplies and
substations).
