Catalyst E2 Max electric bus drives 1100 miles on a single charge

The battery in the record-setting Proterra Catalyst E2 Max bus has 11 times the energy capacity of the 60kWh battery of a 2017 Chevrolet Bolt EV electric vehicle, which held the previous record.

However, the Green Car Report website commented that the principle Proterra used to set the new world record was simply "higher energy capacity in a battery allows a vehicle to travel further". 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.

"The transit market will be the first to transition completely to battery-electric-powered vehicles".

"As we see incumbents and more companies enter the heavy-duty EV market, it has become very apparent that the future is all-electric, and the Sun is setting on combustion engine technology", said chief executive Ryan Popple.

Catalyst E2 battery packs with the new cell provided by LG Chem will be produced at Proterra's battery facility in Burlingame, California, the company said.

The company sells electric buses to municipal corporations, universities, and commercial transit agencies in the US.

"The makers of this bus prove that really all you need is a bit of ambition and determination". As more and more cities around the world seek a solution to the threat of air pollution, Proterra has shown that an electric battery is a viable source of clean transport. Now, this is a hard comparison to make as a bus is a lot larger than a auto, however, it does show off the triumph Proterra has attained.

Ben Wood, an analyst from CCS Insight, said Proterra's accomplishment could help overcome one of the biggest issues in the adoption of electric vehicles: "range anxiety".

"This record achievement is a testament to Proterra's purpose-built electric bus design, energy-dense batteries and efficient drivetrain".
