Rebaba Raises $4.6 Mn to Expand Energy Storage Using Repurposed EV Batteries

The funding was led by Sistafund and EIT Urban Mobility, with support from existing shareholders and new investors from across Europe. Rebaba will use the money to expand its battery energy storage systems, which use repurposed electric vehicle batteries.

Felix Kruse, co-founder and CTO of Rebaba, said "the company's platform has been designed to work with different types of electric vehicle batteries while using standard components for other parts of the storage system. By keeping the complexity within our core technology, we can assemble the rest of the Rebaba system from standard, locally available components. In practice, this means that essentially any technician, anywhere in the world, can build a Rebaba system."

Rebaba was founded by Paula Runsten and Felix Kruse. The company develops energy storage systems that give used electric vehicle batteries a second life.

Rebaba combines old EV batteries with its own technology to create energy storage systems for homes, businesses, and industrial facilities.

EV batteries are often removed from vehicles before they are completely worn out. This means they can still be useful for other purposes where their size and weight are less important.

According to Rebaba, EV batteries can still have around 70% to 80% of their useful life left when they are taken out of vehicles. The company aims to reuse these batteries instead of letting them go to waste.

Rebaba will use the new funding to expand its CircularHub production facility in Stockholm. The company aims to increase the facility’s annual production capacity to 40 MWh and plans to hire more employees for different roles.

The company is also preparing to open more CircularHubs outside Sweden as it expands into other European markets.
