Smart Battery Balancing

Battery packs are prone to capacity, thermal, and aging imbalances in their cells, which limit power delivery to the vehicle. Spurred by this issue, we propose a new class of battery balancing systems, called “hybrid battery balancing,” capable of simultaneously equalizing battery capacity and temperature while enabling hybridization with additional storage systems, such as supercapacitors. Our research combines battery equalization and hybridization into a single system, paving the way for a lower cost. Through validation in a small-scale prototype, we have been demonstrating that this hybrid balancing concept can significantly decrease energy losses and battery stress while increasing a vehicle’s range as compared to conventional balancing methods.
