Connected Energy

Connected Energy develops battery energy storage systems through the use of second life electric vehicle batteries. The company’s 300 kW E-STOR battery energy storage system is designed for commercial applications.

The product comes in the form of a 20 ft container and is made using 24 second life Renault EV batteries. The battery system can be used individually or as multiple systems working together as per the customer’s requirements. Furthermore, Connected Energy’s control system communicates directly with all batteries to provide real time monitoring and control. The battery system's modular design makes it possible for batteries to be easily exchanged if required.

The next generation of Connected Energy’s E-STOR battery energy storage systems, released in 2023, range from 1 MW up to 10 MW. The systems are designed for larger, commercial-scale, and industrial applications and will be suitable for both in-front and behind-the-meter applications. 

The company’s batteries are automated and optimized by its cloud-based energy management software. It allows the system to be charged and discharged to complement the site’s operations and responds to multiple parameters on or off-site according to a pre-set hierarchy of priorities. Customers are provided access to the online portal to monitor the performance of the system and the system dashboard visualizes the data.

The company operates from its headquarters in Newcastle, UK, and has also established a technical center in Norwich which undertakes design, development, prototyping, integration, and testing.
