Stellar Industries Launches Emission-Free Hybrid Power Source for Service Trucks
According to Equipment Journal, Stellar Industries has introduced the Hybrid Power Source (HPS), a fully integrated, emission-free power system for service trucks that operates hydraulic tools, cranes, compressors, and stabilizers without relying on the chassis engine.
A New Power Standard for Service Trucks
The HPS combines automotive-grade lithium-ion technology with a modular hydraulic power system to deliver clean, quiet energy at the jobsite. The system provides up to 12.8 kWh of output and up to eight hours of runtime in its slimmest, lightest configuration, which weighs in at 358 kg. Equipment Journal reports the unit can be mounted in the load bed or side pack, making it suitable for new builds and retrofits alike.
Recharging happens automatically through the truck’s alternator while driving, or via a standard 120V connection, reducing idle time and fuel consumption. The system is designed to work with both internal combustion engine and electric vehicle chassis, positioning it as a bridge between current fleets and future zero-emission operations.
Earlier this year, HPS was named a finalist in ConExpo’s Next Level awards. “Our team works hard to bring the needs of our customers to life, and that’s exactly what the HPS stands for. We are continuously improving our products to better serve an industry that continues to push the envelope,” said Tim Davison, Vice President of Sales and Marketing for Stellar.
The system also incorporates integrated thermal protection and a heating system to maintain charging performance in cold conditions, a critical feature for Canadian and northern US field operations.
What It Means for Subcontractors
- Idle reduction compliance: Anti-idle capability helps service companies meet increasingly strict no-idle regulations in US states and Canadian provinces without sacrificing tool performance at the jobsite.
- Retrofit flexibility: At 358 kg and designed for load bed or side pack mounting, HPS can be added to existing service trucks, meaning fleets don’t need to wait for a full vehicle replacement cycle to start reducing emissions.
- Cold-weather readiness: The built-in heating system addresses a real operational gap for crews working in northern climates, where battery performance typically degrades in extreme cold.
- Fleet standardization: Because HPS integrates with Stellar cranes, stabilizers, and compressors as a single power source, it can simplify technician training and reduce service complexity across mixed fleets.
- EV transition runway: Compatibility with both ICE and EV chassis means companies can adopt HPS now and carry the same system forward as they eventually shift to electric truck platforms, protecting the capital investment.
