About Connected Energy

We operate internationally to provide and enable second-life battery energy storage systems.

Our proven technology enables electric vehicle (EV) batteries to have a second life deployed in commercial scale stationary energy storage systems. These systems will have lower capital, cycle and environmental costs compared to first-life energy storage systems. Using our proprietary technology, we are also able to maximise the value of MWhs under our control.

Positioned at the intersection of the energy trilemma, the electrification of transport and the circular economy our team is focussed on positive impact.

Why second-life batteries?

Electric vehicle batteries provide around 10 years of on-board use before their reduced range makes the vehicle impractical. If the batteries are recycled at this point, around 40% of the value embedded in the batteries, and the associated environmental impact, will be wasted.

Industry projections suggest that in 2030 around 1 million tonnes of electric vehicle batteries could become available for reuse and by 2035, global requirements for stationary energy storage could be met by 2nd life batteries.

Giving batteries a second life:
• Realises more value from the embedded resources,
• Displaces the environmental impact of new battery production,
• Delays recycling until processes are more efficient and cost effective.
• Increases the residual value and improves the economics of transport electrification.

How does it all work?

We work with many EV manufacturers, recyclers, funders, energy storage users and policy makers globally to enable the reuse of EV batteries using our E-STOR technology.

Our battery agnostic, E-STOR energy storage systems have been developed to enable thousands of batteries, with varied levels of degradation, to be aggregated, controlled and reused as one stationary energy storage system.

This technology has been proven, commercialised, scaled up and installed in the UK, Belgium, Germany and the Netherlands in collaboration with our network of international partners.

E-STOR is proven in multiple applications, is underpinned by extended warranties, has passed energy sector compliance and validation tests and is ready for further scale up and international deployment as battery availability ramps up.

Future Transport Systems

Connected Energy is wholly owned by Future Transport Systems (FTS). FTS undertakes internal research and development that is funded from internal and other public and private sources. Connected Energy was established to commercialise these developments.

Founded in 2009, FTS delivered some of Europe’s leading e-mobility related pilot projects including major EV fleet and infrastructure trials, strategic studies, technology development and evaluation.
