This paper introduces a hardware platform for automated battery changing and charging for multiple UAV agents. The automated station holds a buffer of 8 batteries in a novel dual-drum structure that enables a “hot” battery swap, thus allowing the vehicle to remain powered on throughout the battery changing process. Each drum consists of four battery bays, each of which is connected to a smartch...

In a 24 x 7 mobile world experiencing a proliferation of handheld devices, battery life can be a limiting factor. In particular, handheld displays consume substantial battery power. One strategy to potentially reduce display battery consumption and support a positive user experience is to adopt emerging display technologies (e.g., OLEDs) that support energy-aware interfaces. The research report...

I I I I advanced lightweight technologies for the Ballistic Missile Defense Organization (BMDO). One of the key technologies was the first use of a multi-cell nickel hydrogen (NiH2) cornmon pressure vessel (CPV) battery. The 5.0 inch diameter, 22 cell, 15.0 ampere-hour NiH2 CPV battery was manufactured by Johnson Controls Battery Group Inc., (JCBGI). Battery test and integration was performed b...

In this paper, battery/ultracapacitor hybrid energy storage system (HESS) is proposed for electric vehicles, it is used to large dc-dc converter by using ultra capacitor and battery. It is also use the dc link for the purpose of maintain the peak voltage value. By the help of battery and ultracapacitor they are operate. The battery is used to charging the capacitor in case of discharge the capa...

Purpose: Polarization voltage of the lithium-ion battery is an important parameter that has direct influence on battery performance. The paper aims to analyze the impedance characteristics of the lithium-ion battery based on EIS data. Design/methodology/approach: The effects of currents, initial SOC of the battery on charge polarization voltage are investigated, which is approximately linear fu...

Lithium-ion batteries are widely used in many electronic systems. Therefore, it is significantly important to estimate the lithium-ion battery's remaining useful life (RUL), yet very difficult. One important reason is that the measured battery capacity data are often subject to the different levels of noise pollution. In this paper, a novel battery capacity prognostics approach is presented to ...

In an electrical energy storage and delivery system, a parallel connection of battery modules can be used to increase the storage capability and power delivery demands. Parallel connection of batteries requires a robust battery management system as batteries may have different operating parameters such as state-of-charge (SoC), open-circuit voltage (OCV), internal resistance or battery chemistr...
