Volvo EVs to get fast-charge battery tech boost from start-up Breathe 1024 618 Energy Storage Journal

March 21, 2024: Volvo Cars is to use charging software developed by UK start-up Breathe Battery Technologies in its new generation of fully-electric vehicles.

Volvo said on March 12 the algorithm-enabled software is expected to reduce the time it takes to charge a fully-electric Volvo from a 10-80% charging state by up to 30%, subject to battery pack design, while maintaining the same energy density and range.

According to the auto giant, the charging time improvements will last across the full battery life cycle without impacting its health status.

Breathe was spun out of Imperial College London in 2019.

The collaboration is the result of a sourcing agreement for the battery tech firm’s flagship ‘Breathe Charge’ product, and represents the latest investment by the Volvo Cars Tech Fund — the auto firm’s corporate venture capital arm.

Breathe said its software, unlike traditional stepped charging, relies on pre-determined rules using adaptive charging to dynamically control the battery in real-time.

The software manages the charging process in line with the battery’s health while avoiding the risk of lithium plating, which can harm the battery’s performance and lifespan.

Breathe CEO Ian Campbell said deployment of its technology at scale through Volvo opens doors to innovative car designs and performance improvements.
