Dragonfly expands DualFlow Power Pack to 24V platforms
Dragonfly Energy is expanding its DualFlow Power Pack with a new 24-volt configuration, giving fleets another option to reduce idling while supporting driver comfort and protecting chassis batteries.
Announced at the TMC 2026 Annual Meeting & Transportation Technology Exhibition, the updated system is designed to align with the adoption of 24V electrical architectures in North American trucks—especially as OEMs begin to use systems that have been standard in Europe.
The DualFlow system, originally developed in partnership with Werner Enterprises, is built to power sleeper cab “hotel loads” while maintaining battery health. The new 24V platform extends that capability to trucks equipped with higher-voltage chassis systems.
"The chassis batteries still get drained when there's no auxiliary power pack involved," said Wade Seaburg, CCO at Dragonfly. "So we're able to support the truck batteries at 24 volts trickle charge...while still maintaining the entirety of the load that the driver needs for his comfort."
He added that the system is engineered to keep trucks powered through a full 10-hour rest period, supplying energy for in-cab loads like refrigeration and personal electronics.
The DualFlow Power Pack’s 24V configuration includes:
- Alternator charging
- Integrated battery heating for cold-weather operation
- Battery management system to regulate charge and protect electrical components
