Sws Ps Power Solutions Gmbh

What Sws Ps Power Solutions Gmbh does

SWS PS Power Solutions GmbH is an Austrian private limited company headquartered in Graz that develops and sells the SWS-PowerBox®, an autonomous energy supply system for cooling units on rail freight wagons. The system pairs LFP (lithium iron phosphate) battery technology (up to 80 kWh, operating from -25°C to +40°C) with a hydraulic axle generator that recovers kinetic energy during transit, eliminating diesel-generator dependency for refrigerated container transport. SWS complements the hardware with an IoT-based Remote Monitoring System offering two-way communication, transport run tracking, alarm functions, and remote maintenance, developed in partnership with optiMEAS GmbH. Beyond rail, the company offers SWS Battery Solutions targeting aviation, maritime, robotics, transport, and industrial applications.

The company monetizes primarily through hardware sales of the SWS-PowerBox® and SWS Battery Solutions, supplemented by technical services (hourly rates for inspections, commissioning, troubleshooting), fixed-price service packages, cold-chain training programs, and custom engineering/consulting engagements. Go-to-market is enterprise-direct, targeting rail freight operators, wagon leasing companies, and logistics firms; channels include major industry exhibitions (transport logistic, Connecting Europe Days), on-site training at customer terminals (e.g., VTG's Giovinazzo terminal), LinkedIn presence, and newsletter communications. The company has established a representative office in Taiwan (SWS Asia) to source technologies and broaden its supply chain presence. With 100+ systems deployed across Europe, SWS positions itself as the first mover in climate-neutral refrigerated rail transport, directly aligned with the European Green Deal target of 30% rail freight market share by 2030.

Key strategic partners include VTG (rail logistics), ATP Hydraulics (manufacturing in Küssnacht, Switzerland), optiMEAS GmbH (monitoring technology), the Rail Innovators Group consortium (Railrelease, Raillogix, Combo Wagon Service), FH OÖ (academic DFMA R&D), and the Pro-Rail Alliance. The company received the Innovation Award 2023 in 'Sustainability in Logistics' from CNA e.V., Cluster Bahn Technik, and Logistik Initiative Bayern. SWS is privately held with no disclosed institutional investors, no public listing, and a small named leadership team led by CEO/Managing Director Patrick Sluga.

Core offering

SWS PS Power Solutions GmbH develops and manufactures the SWS-PowerBox®, an autonomous battery system that powers refrigeration units on rail freight wagons during transport. The system relies on LFP (lithium iron phosphate) batteries kept continuously charged by hydraulic axle generators mounted on the wagon, enabling diesel-free, climate-neutral refrigerated transport. A web-based remote monitoring platform provides real-time visibility into battery status, location, and temperature data of the load.

Product overview

SWS Power Solutions offers a portfolio of battery-powered electrification systems for sustainable cold chain logistics, primarily focused on rail freight transport. The core product is the SWS-PowerBox® (available in standard and V-5.0/UF underframe variants), which provides autonomous CO2-free energy supply for temperature-controlled containers on rail wagons through LFP battery technology and kinetic energy recuperation. This is complemented by a Remote Monitoring System (IoT-based platform with two-way communication) and SWS Battery Solutions for broader industry applications. The products share common LFP battery technology and monitoring capabilities, enabling climate-neutral refrigerated transport.
