About Superstream
Superstream develops, designs and manufactures modular battery systems for electric vehicles and machines in motion. Its 48 V 99 Ah and 24 V 198 Ah modules are sealed, connect side by side into one system, and include an onboard display and a connected battery management system that streams charge, voltage and health data. Mechanical and PCB design, embedded battery management firmware and connected fleet applications are developed in-house.
The company serves manufacturers and operators of electric vehicles and machines and says it supplies customers around the world.
Superstream is based in Helsinki, Finland, where both models are designed and assembled. The company was founded in 2020 and grew out of the engineering work its founding team did on electric marine vessels. Its core team lists seven people, and the company describes itself as in a growth phase and hiring.
Product: Modular, connected battery modules (48 V 99 Ah and 24 V 198 Ah) that link into scalable battery systems for electric vehicles and machines.
