A Proterra electric bus just drove 1,100 miles on a single charge

The Catalyst E2 Max went 1,101.2 miles, thanks to a 660kWh battery.

Proterra revealed that one of its Catalyst E2 Max electric buses just set a new world record for the longest distance traveled by an electric vehicle on a single charge. The bus, which packs a hefty 660kWh of storage—equivalent to 11 Chevy Bolts—drove a total of 1,101.2 miles (1,772.2km) at the Navistar Proving Grounds in Indiana. It’s quite an impressive feat, considering the previous record holder was a lightweight experimental single seat EV.

While 1,100 miles is a lot more than an average bus drives in a day, Proterra’s record may prove quite helpful in persuading range-anxious transit authorities to ditch internal combustion in favor of battery power for future fleets.

Of course, the other factor is how long it takes to recharge. This is probably less of an issue with vehicles like buses, delivery trucks, and garbage trucks that spend their lives crawling around cities, since that kind of low-speed, stop-and-go duty cycle plays right into the strengths of an electric powertrain, and the vehicles can recharge at the end of their route. Proterra also developed a high speed charging system for buses (which it’s offering to anyone without licensing fees), although even with its high-voltage system in operation, the 660kWh record-breaking bus would still need at least an hour to get back to a full charge.
