Research on Outdoor Mobile Music Speaker Battery Management Algorithm Based on Dynamic Redundancy

In terms of the battery management system a mobile music speaker, reliability optimization has always been an important topic. This paper proposes new dynamic redundant algorithm based on existing fault-tolerant structure lithium pack. The internal configuration is adjusted according to SOC each battery, and power supply dynamically allocated. selects four batteries experiment with two different algorithms. simulation results show that compared traditional algorithm, extends pack working time by 18.75%, energy utilization rate B1 B4 increases 96.0% 99.8%, respectively. proves can effectively extend improve utilization.
