A New Topology and Control Strategy for a Hybrid Battery-Ultracapacitor Energy Storage System

Xiang, Changle; Wang, Yanzi; Hu, Sideng; Wang, Weida - In: Energies 7 (2014) 5, pp. 2874-2896

This study investigates a new hybrid energy storage system (HESS), which consists of a battery bank and an ultra … lower power rating than those used in the traditional HESS topology. The proposed HESS has four operating modes, and the … battery bank and the bi-directional DC-DC converter operate within their power limits. The proposed HESS is used to improve …

Fluid flow in a porous tree-shaped network: Optimal design and extension of Hess–Murray’s law

Miguel, Antonio F. - In: Physica A: Statistical Mechanics and its Applications 423 (2015) C, pp. 61-71

This paper aims to contribute to the ongoing research on tree-shaped flow structures. Here, we focuses on porous-walled tree-shaped networks, namely the laminar fluid flow. Analytical models are developed for pressure distribution along the porous tree-network and for the hydraulic resistance...

Optimization for a hybrid energy storage system in electric vehicles using dynamic programing approach

Song, Ziyou; Hofmann, Heath; Li, Jianqiu; Han, Xuebing; … - In: Applied Energy 139 (2015) C, pp. 151-162

the best configuration and energy split strategies of a hybrid energy storage system (HESS), including a battery and a … HESS life cycle cost based on a dynamic degradation model of the LiFePO4 battery, which is initially proposed by us. For … shown that the life cycle cost of the HESS initially decreases rapidly with the addition of SCs, though the rate of this …
