The Charging Interface Initiative (CharIN e.V.), an international organization developing and establishing the Combined Charging System (CCS) as the standard for charging battery-powered electric vehicles (EVs) of all kinds, announced that Proterra, a leading innovator in heavy-duty electric transportation, has become its first North American electric bus company member.


Proterra joined CharIN to help ensure heavy-duty EV needs are considered in charging infrastructure standardization discussions domestically and around the globe. The company brings to CharIN transit design, manufacturing and charging expertise, as well as extensive real-world operations experience that will complement and supplement the strong CharIN roster of members and partners.


Already, Proterra vehicles have proven themselves over more than 3.3 million miles of service using the CCS Standard, which leverages passenger market volumes for improved reliability, reduced costs and increased compatibility in yards and across transit agencies. 


By joining CharIN, Proterra is demonstrating its commitment to the development and extension of a successful established standard. Ryan Popple, CEO, Proterra said, “We’re no longer at the dawn of the electric mass transportation revolution, we’re in the midst of it. We will continue to do our part as the North American market leader and champion innovation throughout the electric mobility ecosystem.”
