Hybrid Energy Storage System

This paper introduces improvement efficiency of battery for air-conditioning (A/C) system. Super-capacitor (SCs) is mounted with Lithium-ion battery called hybrid energy storage system (HESS). The system modeling of heat system in passenger room and battery pack are derived to represent system in mathematic model. The characteristic of power loss relative to discharge rate are examined using several models of Li-Ion battery. The relationship between discharge rate and power loss in battery is tested by experiment kits. A/C system of passenger car is simplified to demonstration kit. Single energy storage system (SESS) and HESS batteries are used as energy storage. The both typed of energy storage are tested with on-off control. HESS outperforms rather than SESS. The efficiency of HESS battery is greater than SESS about 57.57% at peak load and 14.34% at rated load.

Due to the increasing concerns about the environmental and economic issues of traditional ships, all-electric ships with energy storage and renewable energy integration have become more and more appealing for the forthcoming future. In this paper, an optimal energy storage system (ESS) capacity determination method for a marine ferry ship is proposed; this ship has diesel generators and PV panels. ESSs sizing optimization and power system scheduling optimization are simultaneously conducted and it is converted to a mixed-integer quadratic programming (MIQP) model with special modeling techniques. The case study shows that the proposed method is flexible and effective, and the relationships between the ESSs size and the discharge rate, life cycle times, or initial investment cost are investigated.

The battery energy storage system (BESS) market is growing rapidly around the world. Lithium Nickel Cobalt Manganese Oxide (LiNiCoMnO2) is attracting attention due to its excellent energy density, high output power, and fast response characteristics. It is being extensively researched and is finding use in many applications, such as in electric vehicles (EV) and energy storage systems (ESS). The performance and lifetime characteristics of a battery change for varying Ni contents. The consideration of these characteristics of a battery allow for a more reliable battery management system (BMS) design. In this study, various experiments and analyses were carried out using a lithium-ion battery (NCM LIB) with differing Ni contents. In particular, the following two combinations were studied: LiNi0.5Co0.2Mn0.3O2(NCM523) and LiNi0.6Co0.2Mn0.2O2 (NCM622). Various analyses were performed, such as C-rate (C-rate is the charge-discharge rate of a battery relative to nominal capacity) performance tests, hybrid pulse power characterization (HPPC), accelerated deterioration experiments, electrochemical impedance spectroscopy (EIS), parameter estimations of battery equivalent circuits through alternating current (AC) and direct current (DC) impedance, and comparative analyses of battery modeling.
