Volvo Penta Unveils Mobile BESS at IAA Transportation 2026

Volvo Penta is exhibiting its Battery Energy Storage System (BESS) subsystem alongside the Hivolt 380X at IAA Transportation 2026 in Hannover, Germany. Developed in collaboration with Contour Advanced Systems, the Hivolt 380X is a ready-to-deploy mobile BESS unit built around Volvo Penta’s proven battery technology. The system is designed to alleviate power bottlenecks in transport electrification by delivering fast EV charging to locations where permanent infrastructure is unavailable or grid capacity is severely constrained.

For transport and logistics operators, mobile battery-powered charging units can significantly shorten deployment timelines. They bypass the need for lengthy municipal permitting processes, extensive civil works, or reliance on fixed grid connections. Engineered for continuous, heavy-duty use, the Volvo Penta BESS subsystem combines a high-energy-density battery pack with a favorable C-rate for rapid charging and discharging. The system is managed by a robust, automotive-grade battery management system (BMS) that ensures operational performance, longevity, and cybersecurity.

Volvo Penta's partnership model provides the core battery foundation and application expertise, empowering system integrators like Contour Advanced Systems to manufacture specialized, field-ready charging solutions. The resulting Hivolt 380X unit is designed and manufactured in Europe, offering commercial operators a flexible energy storage solution for temporary locations, remote sites, or to supplement limited grid connections during peak EV charging demand.




Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The transition to zero-emission commercial transport is currently constrained by the physical limitations of local electrical grids. Heavy-duty electric trucks require high-power DC fast charging, often necessitating massive grid upgrades, new substations, and extensive trenching. Mobile Battery Energy Storage Systems (BESS) act as an essential buffer for this infrastructure lag. By slowly drawing power from a low-capacity grid connection or intermittent renewable sources, a BESS can store energy over time and discharge it instantly at high C-rates to rapidly charge commercial vehicles. Furthermore, by leveraging the Volvo Group's broader electromobility platform—including its specialized thermal management systems and 600V DC architecture—Volvo Penta ensures these modular units can withstand the aggressive cycling demands of commercial fleet operations while maintaining stringent cybersecurity standards across both the vehicles and the charging ecosystem.
