Abstract
In order to investigate the effect of thermal management strategy on the temperature and life of battery system,this paper took hybrid ship as the research object,built the equivalent circuit model of battery cell to calculate the heat generation of cell,analyzed the composition structure of battery system,built the thermoelectric coupling model of battery system,and conducted corresponding test and simulation benchmarking for typical operating conditions of hybrid ship.Based on the thermoelectric coupling model,the thermal management strategy of the battery system is built.By calculating and comparing the influence of static strategy and dynamic strategy on temperature characteristic and life of battery system,this research method provides the direction for the thermal strategy research of the hybrid ship battery system.
