Engineering Brief

Portable

A single transportable cabin houses 540 kWh of NCA storage and a 180 kW CCS2 charging stack — easy to relocate around a site.

Plug-and-Play

Standard CEE 100 A AC input, CCS2 charger output and load-balanced dual-port operation make site setup straightforward.

Smart

Software-driven EMS with AI diagnostics, autonomous fault recovery, fire detection and remote console access.

Mission Use Cases

Electric Construction Equipment

Charges Volvo compact electric machines and other CCS2-compatible construction equipment with two simultaneous load-balanced outputs.

On-site DC Fast Charging

On construction and industrial sites without grid access — or with constrained grid capacity — for any CCS2-compatible load.

Site Power and Equipment Loads

Powers on-site electrical equipment via the integrated charger / PCS output, with remote monitoring and predictive maintenance.
