Volta Power Systems Partners with Stellar Industries to Reduce Idling on Utility Service and Work Trucks with Li-ion Auxiliary Power System


As 23 states across the US continue to strengthen enforcement of anti-idling regulations to improve urban air quality, Volta Power Systems partnered with Stellar Industries to provide lithium-ion power systems that reduce idling from fleet utility and work trucks. The auxiliary system stores enough energy to provide all-day power for hydraulics, power tools, and multiphase worksite power without idling. Available as an accessory to replace a traditional hydraulic system on a work truck, Stellar Industries offers the Hybrid Power System (HPS) through its American Eagle brand.

“As the need for hybrid technology continues to grow, we are excited to bring the HPS to our customers,” says Tim Worman, product manager at Stellar Industries. “The capabilities of the HPS will enable fleets to upfit their vehicles to meet sustainability targets while providing the power needed to operate their hydraulic equipment. We’re proud to partner with Volta and offer their idle-free lithium-ion systems on our work trucks as our customers find this hydraulic system replacement option easy to use, quiet, and able to meet sustainability strategies.”

Idling is expensive. As of August 2019, 23 states have idling-reduction or restrictive emissions laws  with many increasing enforcement and levying fines. Accounting for reductions on fuel, maintenance, and depreciation from idling, it’s estimated the hybridized system could save operators more than $14,800 per year over a traditional chassis-driven hydraulic system.

“Volta Power Systems is meeting a genuine need for innovation in the work truck industry for reduced emissions at a quarter of the cost of a full-EV solution,” says Jack Johnson, CEO at Volta Power Systems. “These systems are scalable and flexible, meeting the specific power needs of each vehicle regardless of chassis. Whether on a new truck or retrofit, fleet managers can green an entire fleet with a standardized platform.”

Additionally, Volta integrates into vehicles as a complete system including NMC energy storage (the same chemistry used for automotive electric vehicles), under-the-hood generation through a 51V alternator, and distribution to any DC or AC voltage necessary including two and three-phase service.

This collaboration further cements Volta Power Systems’ leadership in automotive-grade energy storage solutions for transportation and recreational vehicles.
