An electric bus has set a new world record for heavy vehicles, by being able to run 1770 km (1100 miles) on a single battery charge.
The Catalyst E2 Max, built in the US by Proterra, covered this distance in the American company test track without having to stop to recharge the electric battery. The E2 Max broke the previous record of 1630 km (1013 miles), which belonged to a mini-bus.
The E2 Max is the version with maximum battery charge, based on the chassis Catalyst 40. This 13 meters model is available with a number of batteries, the largest of which has a capacity of 660 kWh. It was with this battery that the E2 Max covered the 1770 km, beating the 970 km done with the 440 kWh version last year, and 415 km with the 257 kWh version in 2015.
This autonomy was done on an empty bus. In a normal route, full of passengers and making several stops, the Proterra announces an autonomy of 560 km with the 660 kWh model and 400 km with the 440 kWh model. The American company has 400 electric bus copies circulating in 42 cities.
