AI Technical Summary
Technical Problem
Current battery cooling systems fail to effectively manage temperature differences and state of health (SOH) variations among battery modules, leading to non-uniform degradation and inefficient cooling.
Method used
A battery system with a master management unit controlling cooling fans based on temperature, SOH, and state of charge (SOC) of multiple battery modules, using equations to determine optimal rotation speeds and power distribution for each module, ensuring uniform cooling and extended module life.
Benefits of technology
This approach effectively reduces temperature differences and life deviations among battery modules by individually tailoring cooling to each module's state, thereby enhancing battery performance and longevity.
