Project

California Collaborative Advanced Technology Drayage Truck Demonstration Project

This project advanced the development and commercialization of zero- and near-zero emission trucks, building on the success of earlier demonstration efforts. Phase 1 featured trucks with existing technologies, including Kenworth’s CNG range-extended plug-in hybrid electric trucks from the ZECT 2 program and Volvo’s diesel plug-in hybrid electric truck developed with DOE support. In Phase 2, OEMs expanded deployments and introduced additional innovations.

Vehicles/Equipment Funded:

44 pre-commercial Class 8 zero- and near-zero emission drayage trucks and infrastructure was deployed into fleets:
  • 25 BYD battery electric trucks with 100 to 124-mile electric range
  • 12 Peterbilt/Meritor battery electric trucks with 100 to 150-mile electric range
  • 2 Kenworth CNG range extended plug-in hybrid electric trucks with a 50 EV & 200-mile HEV range
  • 3 Volvo diesel plug-in hybrid electric trucks with 30 mile electric/400-mile range
  • 2 Volvo battery electric trucks with 150-mile electric range

Lessons Learned:

  • BYD: Early models faced challenges with telematics software compatibility, battery pack software, and the use of proprietary charging connectors. Starting with the Gen 2 configuration, BYD transitioned to standard CCS1 connectors and rewired power to support lift gates for beverage delivery. These issues were addressed in later versions.
  • Kenworth: Supply chain limitations and other challenges revealed that the commercial vehicle supply chain was not yet ready to support hybrid electric trucks at scale. Ongoing work focused on refining the hybrid drivetrain for reliable operation in both electric and hybrid modes.
  • Peterbilt: Addressed challenges related to charging rates, infrastructure costs, and varying range and efficiency across fleet duty cycles. Improvements included faster onboard charging and enhanced energy storage systems.
  • Volvo: Focused on refining two proven technologies for seamless operation, validating the PHEV battery-engine interface, and continuing to evaluate battery management systems for durability and performance.

Status Updates:

Equipment In-service:
  • BYD: All 25 vehicles deployed
  • Peterbilt: All 12 vehicles deployed
  • Kenworth: Both vehicles deployed
  • Volvo: All three trucks deployed, two battery electric trucks deployed in Fresno on March 2022
