Our second life story: Thinking ahead for third life battery usage

As one of the leading innovators behind battery energy storage in the UK, Connected Energy has long been at the forefront of EV battery innovation, so we spoke to Operations Manager, Tania Saxby, about the company’s latest forward-thinking plans.


Twelve years ago, Connected Energy’s managing director, Matthew Lumsden had a professional interest in the world of electric vehicles, but was already thinking ahead to what would come next when the EV batteries had run their course in their vehicles.

Today, that vision has become the centre point of our company’s existence. We produce safe, robust solutions for utilising EV batteries, and turning first life batteries from electric vehicles into viable, cost-effective, sustainable second life batteries. But what happens after that?

It’s a question that is starting to pop into the minds of OEMs and other supply chain partners in the battery energy storage and renewable energy sectors, but is there a successful solution just yet?

Leading the way

Operations manager, Tania Saxby, is leading the way in Connected Energy’s efforts to get ahead of the curve once again with the notion of a ‘third life’ in the battery lifecycle that ensures we really can deliver a circular economy when it comes to battery energy storage.

We work with several partners and suppliers in the effort to perfect the third lifecycle stage of a battery and how once it has been through its iteration as an EV battery, and as an energy storage solution, it can be safely and efficiently recycled.

Now the UK doesn’t yet have the facilities to do this safely, effectively, and on a large scale, which is where the RECOVAS project comes in, on which Connected Energy is a proud partner along with EMR, JLR, Bentley, BMW UK, Warwick Manufacturing Group (WMG), Health and Safety Executive, and Autocraft.

We are working on the RECOVAS project, alongside car manufacturers, recyclers, and other battery experts, to scale up the reuse, remanufacture and recycling of EV batteries from their end-of-life state.

Improving sustainability for the long-term

In our current second life stage, Connected Energy successfully ensures that batteries aren’t just thrown into recycling, or disposed of, they are used successfully for energy storage. This gives threefold benefits: enabling efficient storage of renewable energy, managing peak loads or solving capacity issues on site, and helping to improve sustainability for our customers.

The importance of RECOVAS is that we, with our partners, would be able to offer a longer lifecycle with our use of EV batteries for energy storage. Then in turn, hopefully, we can safely reuse, recycle, and remanufacture batteries for additional longevity.

Tania adds: “EV batteries in their first life are expected to last up to ten years. With our storage solution, we can extend that to an additional ten years added to that battery. If we can perfect that third stage, we can add further longevity reducing the need to mine for raw materials and provide a much more sustainable lifecycle for EV batteries already in, and coming, to the market.”


As we develop our battery energy storage solutions, expanding our offering and how diversifying this for different EV batteries coming into their second life stage, we also are impassioned about supporting RECOVAS in ensuring the UK and Europe can successfully utilise a third life stage to further improve our renewable energy development and sustainability efforts.
