Research on Lifetime Optimization of Unmanned Ship Lithium Battery Pack Power Supply System Based on Artificial Fish Swarm Algorithm

摘要

New energy is an important direction for the development of unmanned ships. The intermittent and random characteristics of new energy have seriously affected the support of new energy to the load. The access of energy storage devices effectively solves the instability of new energy. This article uses the three lithium battery power supply system as an example to explore the relationship between the service life of the unmanned ship's lithium battery pack power supply system and the battery capacity, charging current, and discharge current. At the same time, the artificial fish swarm algorithm is used to optimize the battery capacity, charging current, and discharge current of the three-lithium battery-powered system to extend the life of the three-lithium battery-powered system.
