Volvo Penta launches compact BESS for energy storage

Volvo Penta has introduced a compact, energy-dense BESS subsystem, offering fast-charging, transportable power solutions for construction and mining sectors

Tightening emissions regulations, along with increasing electric demands that surpass grid capacity, have driven a surge in energy storage needs within the construction and mining sectors. To address these challenges, Volvo Penta has introduced its energy-dense and compact Battery Energy Storage System (BESS) subsystem, designed to offer transportable and fast-charging benefits. This solution provides system integrators and BESS manufacturers with a reliable option for deploying energy storage in microgrid scenarios such as quarries, urban restoration sites, and other demanding environments.

Powering future operations 

The construction and mining industries face several energy-related challenges. Some sites have access to grid capacity and electricity but require fast charging or peak shaving solutions to optimise power usage. Others must develop energy strategies to generate or deliver power due to grid limitations, particularly when projects are not sized accordingly from the outset. Additionally, businesses and worksites in transition phases may find themselves neither fully off-grid nor completely secure in their energy capacity for ongoing projects. Volvo Penta’s BESS subsystem presents an effective solution to these challenges, supporting the growing power demands of heavy-duty industries that exceed grid capabilities or face restricted grid connectivity. These energy storage systems can seamlessly integrate with renewables or other power generation assets, ensuring a stable and reliable power supply crucial for large-scale or remote operations transitioning to electrification.

Volvo Penta’s BESS subsystem is particularly well-suited for battery-electric vehicle (BEV) charging, offering a favorable C-rate to facilitate fast charging and grid stability in high-demand applications. Given the frequent capacity and frequency challenges associated with electrification, this subsystem provides a crucial solution to maintain consistent energy availability.

Beyond BEV charging, the BESS subsystem also supports microgrid deployment and peak shaving strategies. Its transportable design enables flexible power solutions for zero-emission construction zones and remote mining sites. These energy storage units can power equipment directly on-site and be relocated for recharging without disrupting operations. Furthermore, they enhance stationary equipment functionality by supporting the energy needs of electric excavators, wheel loaders, and crushers, ensuring continuous uptime in rugged work environments.

At the core of Volvo Penta’s BESS subsystem is an energy-dense battery pack with a high-performance C-rating, allowing for efficient fast charging and discharging. Adapted from the proven battery technology used in both on- and off-highway Volvo Group applications, the subsystem is built to withstand tough environmental conditions, with a high IP rating against corrosion and dust. The system also features a DC/DC converter for auxiliary power, a telematics gateway for real-time monitoring, and a thermal management system that optimises performance in various operating conditions. CAN and DC interfaces, derived from Volvo Group’s expertise, ensure secure and reliable data transfer, while a robust Battery Management System (BMS) enhances overall performance, maximizes battery life, and safeguards cybersecurity.

Each Volvo Penta BESS subsystem provides the essential DC energy supply, while original equipment manufacturers (OEMs) manage the AC setup, container integration, and system configuration. This collaborative approach allows for tailored energy solutions that meet the unique needs of each customer.

Volvo Penta has conducted extensive testing and prototyping with customers and is now ready to bring its production-ready BESS subsystem solutions to the industry. At bauma 2025, the company will showcase how these advanced energy storage solutions can support the transition to electrification in construction and mining. Attendees can visit Volvo Penta’s stand (A4.412) to meet with experts and explore opportunities for integrating BESS technology into their operations.
