It is also noteworthy that the video assumes that the truck would carry a battery equivalent of 1135 litres of diesel. But driving about 600 km a day at 30l/100km the truck only needs about 180 litres (140 kg) of diesel a day. Even with the 1:20 ratio, that would result in a 2.8 tonnes battery. Still punishing in terms of load capacity but much more realistic to offset through weight savings along the drive train.
