Life Optimization of Lithium Battery Based on Fish Swarm Algorithm
Lithium battery has the advantages of high energy density and high energy conversion efficiency.For the energy storage device,its early input cost and service life determine the use cost of lithium battery,so the life of lith-ium battery research is very important.Considering the influence of ambient temperature and charging and dischar-ging current of lithium battery on internal temperature,the life model of lithium battery is derived,that is,the life of lithium battery is related to charging current,discharge current and discharge depth.In order to optimize the life of lithium battery and find the optimal charging current,discharge current and discharge depth,the fish swarm algo-rithm is adopted.In order to verify the feasibility of the proposed algorithm,a simulation model is built,and the sim-ulation results show that the optimization of the life of lithium battery by the proposed algorithm can increase its life and reduce the operating cost of lithium battery.
