This project will develop R-AWARE, a recovery period-assisted battery health management that schedules system operation while considering both system/user requirements and battery health. R-AWARE will improve battery health via relaxation-aware battery scheduling of battery charging/discharging, and recovery-based thermal control. It will advance the science of CPS by uncovering a thorough understanding of battery recovery and exploiting it via a recovery-aware scheduler during system operation. Specifically, R-AWARE is grounded on a thorough understanding of the physical recovery effects on battery health — a new dimension for system optimization existing BMSes fail to exploit. R-AWARE then takes a cyber-physical approach for battery health management by adapting its decisions based on various physical properties of batteries/systems/environment. Finally, R-AWARE improves battery health by exploiting the opportunities offered by user behavior/requirements without degrading user experience. A performance goal of the project is to enable a 40% slowdown in battery health degradation. This project is supported by NSF: CNS-1739577.
