Volvo Energy has introduced a new battery energy storage system (BESS) aimed at providing reliable off-grid electricity in response to increasing global demand for portable power, particularly in the face of more frequent extreme weather events.
The PU500 BESS offers around 500 kWh of usable battery capacity, with a total storage potential of up to 540 kWh. Designed for rapid deployment in a variety of settings, it can be used to supply electricity to remote construction sites, disaster response efforts, or off-grid public events such as festivals. The system is positioned to serve areas lacking consistent access to the power grid.
One of the key features of the PU500 is its integrated 240 kW DC fast charger, which Volvo says distinguishes the unit from other battery storage solutions on the market. “With an integrated CCS2 charger, the PU500 is designed to work with all brands of electric equipment, trucks, and passenger cars,” said Niklas Thulin, Head of BESS Product Offer at Volvo Energy. “This ensures that no matter what type of electric vehicle or machinery you rely on, the PU500 can provide the power you need, making it a truly flexible solution for any grid constrained site or location.”
The unit is capable of recharging heavy-duty electric equipment—including trucks and wheel loaders—in under two hours. According to Volvo, the PU500’s daily output can support the charging of up to three electric heavy-duty trucks or 20 electric passenger vehicles, underscoring its potential value in emergency scenarios and temporary work sites.
