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...

The effects of a pulse charging technique on charge–discharge behavior and cycling characteristics of commercial lithium-ion batteries were investigated by comparison with the conventional direct current (dc) charging. The impedance spectra and cycling voltammograms of Li-ion batteries cycled by both protocols have been measured. The individual electrodes in the batteries have also been examine...

The economic viability of on-road wireless charging of electric vehicles (EVs) strongly depends on the choice of the inductive power transfer (IPT) system configuration (static or dynamic charging), charging power level and the percentage of road coverage of dynamic charging. In this paper, a case study is carried out to determine the expected investment costs involved in installing the on-road...

Full charge capacity (FCC) refers to the amount of energy a battery can hold. It is the fundamental property of smartphone batteries that diminishes as the battery ages and is charged/discharged. We investigate the behavior of smartphone batteries while charging and demonstrate that the battery voltage and charging rate information can together characterize the FCC of a battery. We propose a ne...

This paper presents the investigation of a novel concept involving the combination of piezoelectric and new thin-film battery technology to form multifunctional self-charging, load-bearing energy harvesting devices. The proposed self-charging structures contain both power generation and energy storage capabilities in a multilayered, composite platform consisting of active piezoceramic layers fo...

The charging profile and the quality of the charging system play a key role in the lifetime and the reliability of the battery. In this research, high power 7 Ah LiFePO4-based cells (LFP) have been used to investigate the impact of the fast charging technique on the battery’s lifetime and the charging time. The charging time is an important factor to save time and cost during the battery operat...

Given the limited driving range of battery electric vehicles and lack of sufficient charging infrastructure, locating charging stations is an important decision problem to enable long-distance travels by battery electric vehicles. This paper considers an important political factor in such location problems: the equitable access to charging stations among geographical regions. We propose three t...

1 Corresponding author. ABSTRACT This paper examines the problem of predicting the aggregate grid load imposed by battery health-conscious plug-in hybrid electric vehicle (PHEV) charging. The paper begins by generating a set of representative daily PHEV trips using the National Household Travel Survey (NHTS) and a set of federal and realworld drive cycles. Each trip is then used in a multiobjec...

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...
