Breathe Battery Technologies

Breathe Battery Technologies is a UK battery software company, spun out of Imperial College London in 2019, that builds physics-based battery simulation, cell design, and adaptive charging software for OEM and cell engineering teams. Its API-delivered products — Breathe Design (cell design), Breathe Simulate (validated performance and degradation modelling), and Breathe Charge (embedded adaptive charging, shipped in Volvo EVs) — are consumed through first-party Python client libraries (breathe-simulate, breathe-design) and MATLAB/Simulink integration, backed by a token-authenticated cloud service. The company is venture-backed (Speedinvest among its investors) and profiled in the API Evangelist network for its developer-facing, programmatically accessible battery engineering platform.

Breathe Battery Technologies publishes 1 API on the APIs.io network. Tagged areas include Company, Battery, Battery Simulation, Electric Vehicles, and Energy Storage.

Breathe Battery Technologies’ developer surface includes documentation, API reference, getting-started guide, signup flow, engineering blog, support, authentication, and 11 more developer resources.
