Paccar, Dragonfly Energy Study Battery-Based Idle Reduction
Collaboration Explores Lithium-Powered Options
[Stay on top of transportation news: .]
Battery manufacturer Dragonfly Energy announced a white paper collaboration with Paccar Inc. to explore lithium-powered options for reducing idling and truck fuel costs.
The announcement of the white paper, titled “Reducing Idle Time & Fuel Costs: Lithium Powered Solutions for Commercial Fleets,” took place during a presentation at The Battery Show North America 2025 in Detroit on Oct. 9.
The white paper evaluated the performance, reliability and operational benefits of lithium-powered idle-reduction remedies, such as all-electric auxiliary power units and hybrid systems compared to traditional diesel-powered and AGM-based battery alternatives. The report incorporated real-world fleet trial data and controlled environment testing conducted at the Paccar Technical Center.
“We believe idle reduction remains one of the most immediate and cost-effective ways fleets can reduce fuel consumption and emissions while improving driver comfort. But just as important, the industry is increasingly focused on operational efficiency and maximizing asset utilization,” said Wade Seaburg, chief commercial officer at Dragonfly Energy. “We believe our collaboration with Paccar not only validates the performance of our LiFePO-powered solutions, but also highlights how they help fleets maximize uptime, extend equipment life and get more out of their assets.”

Philip Stephenson, general manager of the Paccar Technical Center, said its collaboration with Dragonfly Energy is focused on helping fleets improve efficiency, driver comfort and reliability.
“This allowed us to evaluate lithium-powered idling mitigation solutions aimed at lowering idle times, extending non-idling sleeper climate control operation and reducing fuel consumption,” he noted.

The white paper also detailed key outcomes for fleets toward lower maintenance costs and extended engine life.
“In practice, reducing preventive maintenance frequency by 25%, from two events to 1.5 per truck annually, saves about $250 per truck each year,” the white paper noted. “For a fleet of 4,000 units, that equates to $1 million in annual maintenance savings, not including the additional value of increased uptime and extended engine lifespan. For fleets outsourcing maintenance, the savings potential is even greater.”
Officials stated that hope is that the report provides fleets with practical insights into how these solutions will perform under demanding operating conditions.
