Fleet EV Charging Infrastructure with 99% Uptime: Inside Greenlane’s Colton Center – Case Study

Delivered in about eight months from groundbreaking to ribbon cutting, the Colton Greenlane Center is the first of several planned sites along the I-10 EV charging corridor, designed to connect California and Arizona and support the rapid expansion of heavy-duty EV charging infrastructure across the western U.S.

Fleet EV Charging Infrastructure Built for 99% Uptime

For fleet operators, charging uptime is non-negotiable. Commercial EV charging stations must operate reliably to prevent missed routes, delayed deliveries, and revenue loss.

Power Electronics deployed 29 standalone DC fast chargers, forming the backbone of the site’s fleet charging network. Since launch, the system has achieved 99% average uptime under real-world fleet conditions, ensuring dependable performance for daily freight operations.

This level of reliability is essential for electric truck charging, where infrastructure must match the intensity and predictability of diesel operations.

Scalable Electric Truck Charging—No Rip-and-Replace Required

As fleet electrification accelerates, scalable EV charging infrastructure is critical.

The standalone NB240 chargers were initially commissioned at 180 kW each to meet early deployment needs. As utilization increased and next-generation vehicles entered operation, the chargers were field-upgraded to 240 kW without replacing equipment or disrupting operations. This flexible approach enabled seamless expansion while protecting long-term infrastructure investments.

With power levels up to 240 kW and a wide operating voltage range, the platform supports both current and next-generation commercial electric vehicles, ensuring long-term usability.

DC Fast Charging for Fleets: Engineered for Real-World Performance

The Colton Center operates as a public charging station supporting multiple fleet operators. This requires DC fast chargers for fleets that are purpose-built for performance, maintainability, and scalability.

Key capabilities include:

• Modular architecture for scalability and simplified service
• Intelligent power distribution across multiple charging ports
• Compact system design to maximize site efficiency

Together, these features enable a reliable commercial EV charging infrastructure that scales alongside demand without compromising uptime or operational continuity.

EV Charging Corridor Development: Connecting California and Arizona

As the first site in a planned three-location rollout, the Colton Center anchors a broader electric vehicle charging corridor along the I-10. Corridor-based infrastructure is essential for enabling long-haul electric trucking, providing reliable, high-power charging access across major freight routes between California and Arizona.

By combining high uptime, scalability, and strategic placement, the Colton Greenlane Center demonstrates how EV infrastructure for fleets can support the transition to zero-emission transport at scale.

Powering the Next Phase of Fleet Electrification

As demand for electric truck charging infrastructure continues to grow, reliability and scalability will define successful deployments.

Power Electronics is proud to support Greenlane and the fleet operators driving this transition, delivering fleet EV charging solutions that perform from day one and scale for the future of freight
