Second life battery solution

Looking for a solution for your second-life batteries? We offer an innovative solution to companies dealing with used batteries that are often seen as liabilities. By transforming these batteries into valuable energy storage systems, we help you turn what was once waste into a marketable asset.

Turning battery liabilities into assets

Enabled by ECO STOR

The challenge of battery replacements
Businesses relying on battery-powered machines or vehicles face costly replacements. Old batteries, classified as “dangerous goods,” come with high recycling expenses and storage challenges.

The Solution: A second life for used batteries
As a leader in second-life battery technology, ECO STOR transforms discarded batteries into valuable, containerized energy storage solutions—delaying recycling costs and maximizing their potential.

The result: New business opportunities
Your used batteries will be considered an asset, and may be used for any desired application, such as fast charging, peak shaving and ancillary services, to either optimize or generate revenue. Use the system for your own energy needs, lease it to customers, or sell it.

Step 1:

Tailor made
We integrate and tailor your batteries into our standard container design. This involves software integration to assure that we can control your batteries, as well as design racks/shelves that fit your batteries physically in our standard system.

Step 2:

First system
You ship the first set of batteries to us in Norway, where we build the initial container, conduct thorough testing and approval processes, and dispatch it to the desired location for commissioning.

Step 3:

Subsequent systems
Upon accumulating sufficient batteries, you can order additional containers. Since your system has been approved, we can avoid transporting batteries to our facilities. Instead, we can ship the completed container directly to the installation site, allowing you to install the batteries conveniently. And also swap batteries once they end their 2nd life.

Bridging the gap towards a circular economy

Amplify your commitment to the green movement with BESS made by repurposed EV batteries. We custom-make tailored BESS to meet your needs. Better for the planet, and better for your energy management.

When the performance of a second life battery is no longer good enough, we remove the battery from the energy management solution and bring it to our recycling facility. Our partner, LiCycle, ensures that as much as 99% of the precious elements in the batteries are recycled and sold to be used for brand-new batteries.

Technical Overview

Dimensions: High cube 20 feet container
Power: Up to 1440kW 400VAC – depending on number of inverters we install
Capacity: Dependent on your battery shape – The most dense container we have made had 2500kWh, the least had 480kWh. The average is approx. 1500kWh
Cooling: We support both air-cooled and liquid-cooled batteries. The container itself is air-cooled as default
Operation Temperature: -20 - +40°C
Lead times: The first system usually takes 6-9 months to develop and deliver, but after that, we can deliver systems in 3-6 months.
Cost: The cost depends on several factors, like how many inverters and how complicated the rack system is. But generally, the cost ends up at 250 – 350 kEUR per system – or 150-200 EUR per usable kWh. We would be able to provide a more accurate quote once we have more information about your batteries.
