How did Proterra get an electric bus to cover 1,100 miles on a charge? A bigger battery, of course

Proterra Catalyst electric busThe laws of physics tend to be immutable, at least until you get into esoteric disciplines like quantum science. In the case of electric vehicles, one law provides that higher energy capacity in a battery allows a vehicle to travel further. That's the principle electric-bus maker Proterra has used to set a new world record for distance traveled by...
