Breathe Charge and Simulate Battery Software

Breathe Battery Technologies is a London-based company founded in 2019 as a spin-out of Imperial College. It develops physics-based software that helps battery and device makers predict cell behaviour and shorten development time.

The product line covers Breathe Discover for cell strategy and candidate selection, Breathe Simulate for cell simulation and degradation analysis, and Breathe Charge for adaptive charging control. Breathe Charge is slated for Volvo's ES90, and OPPO Research Institute is a named customer on the website.

• Cell discovery: Supports battery cell strategy and candidate discovery.
• Cell simulation: Simulates cells and analyses degradation with physics-based models.
• Adaptive charging: Controls charging dynamically to balance speed and cell health.
• Documentation: Offers a knowledge hub, blog and documentation for engineers.
• Laboratories: Operates battery testing laboratories in London to validate models.

• EV and e-motorbike makers tuning fast-charging profiles for new battery packs.
• Battery pack assemblers comparing cell candidates before committing to prototypes.
• Consumer electronics makers extending device battery life through adaptive charging.

Predicts battery performance before costly lab testing, which reduces development spend. Adaptive charging software can shorten charging time without hardware changes. Physics-based models support cell selection and degradation analysis. Pricing pages exist for each product line.

Faster charging and longer battery life are central to EV and consumer electronics competition. Software-defined battery management is gaining attention as manufacturers in Asia scale EV and two-wheeler production, including Vietnamese makers that need cell selection and charging optimisation.
