Volvo Partners with Breathe to Reduce EV Charging Time by 30%

Frustrated by the limitations of traditional battery management, Breathe, a spin-off from Imperial College London, is taking a new approach.

“The current industry standard involves brute force testing,” explains Ian Campbell, CEO of Breathe. “Battery manufacturers essentially test batteries until they fail, then write down the results on a basic datasheet. This approach completely overlooks the complexities of battery electrochemistry and materials.”

Volvo said Breathe’s software reduces charging time from 10 per cent to 80 per cent of battery power by 30 per cent while maintaining the same energy density and range. The company says the improvement in charging time will last for the entire life of the battery without compromising its health.

Unlike pre-determined step-by-step charging, Breathe’s software uses adaptive charging to dynamically control the battery in real time to reduce charging time.

The software uses algorithms to manage the charging process based on the health of the battery to provide an optimal EV charging experience while avoiding the risk of lithium plating, which can impair battery performance and longevity.

Volvo Cars says expansion will be easy as Breathe’s software is fully compatible with the hardware used in Volvo’s new generation of all-electric cars, so there is no need to change the battery pack design or mine additional materials.

Ann-Sophie Ekberg, CEO of the Volvo Cars Technology Fund, said, “Faster charging times in the range where customers typically fast-charge represent an important step in the right direction as we continue to push the boundaries of electric mobility and make electric vehicles more accessible to more people.”
