Range extension, indeed. Proterra says it has an electric bus that can go as far as 180 miles on a single charge. The South Carolina-based company has cut plug-in bus deals with about a dozen municipalities across North America, this news should get the attention of a few more.

In addition to its current fast-charge battery setup that allows for less weight but also supplies less range and requires more frequent recharging sessions, Proterra is unveiling an extended-range battery configuration. That design can carries a maximum of 321 kWh of energy storage, or more than double the max capacity of the fast-charge battery. You can read more in Proterra's press release below.

Last spring, Proterra made news when it tested a battery-electric bus that traveled 700 miles in 24 hours. Factoring in the energy it took to recharge, the bus got a 27 miles-per-gallon-equivalent rating, which is more than four times the fuel economy of a typical bus (and better than a fair number of passenger vehicles, for that matter).

Last fall, Proterra's China-based competitor, BYD, showed off a 60-foot, 120-person electric bus at Houston's American Public Transportation Association Expo that could travel up to 170 miles on a single charge.

Proterra Introduces Extended-Range Electric Bus, Flexible Battery System

New product options can be customized to meet specific route needs

GREENVILLE, S.C.--(BUSINESS WIRE)--To more fully serve the diverse needs of the North American transit market, Proterra Inc., the leading provider of zero-emission battery-electric buses, has launched a new extended-range product line. With the introduction of the new TerraVolt™ XR extended-range battery, Proterra buses can now be configured to travel up to 180 miles between charges. This newest high energy density battery complements the existing TerraVolt™ FC fast-charge battery which has been extensively tested over nearly one million customer revenue miles.

"Adding extended-range capabilities to our existing portfolio of fast-charge products, enables us to help our customers meet more of their most demanding service requirements. The flexibility of our platform allows our customers to more confidently invest in the future of transit."

These two battery packs are key components of Proterra's revolutionary TerraFlex™ energy system and can be used interchangeably in the Catalyst™ vehicle platform. This system enables customers to select the right amount and type of energy storage to meet specific route requirements. Once customized, operators can easily reconfigure battery packs to meet evolving service needs. Both battery systems are compatible with Proterra's on-route and in-depot chargers, resulting in a platform with ultimate flexibility at the lowest cost.

"Operating successfully in cities across the country, the Proterra Catalyst™ is the most energy-efficient transit bus on the market," said Matt Horton, vice president of sales and marketing at Proterra, Inc. "Adding extended-range capabilities to our existing portfolio of fast-charge products, enables us to help our customers meet more of their most demanding service requirements. The flexibility of our platform allows our customers to more confidently invest in the future of transit."

The fast-charge Catalyst™ FC is now available in configurations carrying between 53 kWh and 131 kWh of energy storage and can be fully recharged in under 10 minutes.

The extended-range Catalyst™ XR is now available in configurations carrying between 129 kWh and 321 kWh of energy storage and can be recharged in a little over an hour.

The new product line continues to deliver on Proterra's promise to be the lightest-weight and most energy-efficient heavy duty platform available.
