Multi-mode Power Distribution Strategy With Dual Criteria for Hybrid Energy Storage System in Electric Vehicles
摘要
Abstract
To address the issue of the power distribution between battery and supercapacitor in hybrid energy storage system,a multi-mode power distribution strategy with dual cri-teria is proposed.Based on the electric vehicle dynamics model,the proposed strategy integrates two parameters,the power in the DC bus and the charge state of the supercapacitor,to dy-namically switch the working mode of the hybrid energy stor-age system.The power settings of battery and supercapacitor are adjusted in accordance with the efficiency model of energy storage system.Finally,the power is distributed within hybrid energy storage system.The research on electric vehicle work-ing condition simulation and power distribution strategy was carried out in an experimental platform of hybrid energy stor-age system.The experimental results indicate that,compared with the fixed proportion distribution strategy,the multi-mode power distribution strategy with dual criteria can reduce the av-erage and maximum power of battery by 16.98%and 24.72%respectively,and enhance the energy utilization rate of the hy-brid energy storage system by 5.35%simultaneously.关键词
