PARIS: Connected Energy and Forsee Power have signed an agreement to jointly develop a modular, scalable energy storage system using repurposed electric vehicle batteries, the companies announced Monday.
The partnership will combine Connected Energy’s second-life battery technology with Forsee Power’s ZEN 35 and ZEN 42 battery packs, which are used in roughly 1,500 electric buses across Europe. The deal also includes creating an operating model to support future large-scale deployment.
When EV batteries reach the end of their first life, they can be reused in energy storage systems to support renewable energy projects or commercial power management. This approach extends battery lifespans, reduces waste and provides an additional revenue stream, making EVs more sustainable and cost-effective.
Forsee Power, a global leader in battery systems for electric transport, has equipped more than 4,200 buses worldwide. Connected Energy, founded in 2010, specializes in second-life battery storage with installations across Europe.
“This agreement represents a significant step forward in delivering a new second-life economy for EV batteries,” said Matthew Lumsden, CEO of Connected Energy. “By combining our expertise, we can deliver energy storage technology that offers greater environmental and commercial benefits.”
Christophe Gurtner, chairman and CEO of Forsee Power, said the collaboration aligns with the company’s goal of creating a sustainable battery ecosystem. “The potential is huge,” he added, noting that Forsee will have access to a growing supply of used bus batteries for repurposing.
The first 2.5-megawatt-hour system is expected to be operational in the U.K. by late 2025. Larger projects, each exceeding 25 MWh, are planned for the U.K. and France in the future.
The partnership aims to address rising global demand for energy storage while supporting the transition to a circular battery economy.
