摘要：为了延长蓄电池的使用寿命，采用能量宏观表达法建立了由电池-超级电容构成的HEV复合储能系统模型，提出了非线性比例因子分配控制策略，采用反转规则给出了其控制结构。给出了基于EMR的复合储能系统控制方案，搭建了实验平台。最后对由蓄电池组、超级电容组和DC/DC变换器构成的复合储能系统在特定工况下进行了实验研究，验证了本文所建仿真模型以及所提控制策略的有效性。

Abstract: In this paper, a simulation model for battery/ultra-capacitor hybrid energy storage system was presented by using Energetic Macroscopic Representation (EMR) to improve the battery lifetime. A control strategy namely nonlinear proportion factor dynamic coordination was proposed. A corresponding control structure was deduced from EMR model of HESS through specific inversion rules. Based on EMR control algorithm, the experiment platform was also established. Finally, experiments for HESS consisting of battery pack, ultracapacitor stack and DC/DC converter were conducted under basic modes and specific city drive cycles to verify the effectiveness of established simulation model as well as the proposed control strategy.
Key words: EMR; hybrid energy storage; ultracapacitor; control strategy; bench test
