A company that is building electric vehicle charging stations across Colorado has teamed up with a national trade association representing truck stop operators to make it easier for electric vehicles to recharge nationwide.

ChargePoint and the National Association of Truck Stop Operators announced Friday at a conference in Aurora that they are working together to build high-speed charging stations at more than 4,000 truck stops and travel plazas across the country by 2030.

ChargePoint is the company tapped by the state of Colorado to build build 33 high-speed charging stations along the state’s major transportation corridors. The state awarded a $10.3 million grant in November to ChargePoint, which has built charging stations across the country, Canada and Europe.

The money for the grant came from part of Colorado’s share of the settlement between Volkswagen and the federal government over allegations that the auto company modified computer software to cheat on emissions tests. The stations are expected to be completed by summer.
