The Research of Power Battery with Ultra-capacitor for Hybrid Vehicle

2011
In this note, a novel power battery with ultra-capacitor method is proposed to drive hybrid power system. By using such method, the open problem that high power density and energy density which not be provided simultaneously by the power source of electric vehicles can be solved.

High-power batteries for use in hybrid vehicles

Journal of Power Sources, 2000
Abstract The idea of hybrid vehicles is not a recent development; as early as the 1960s, several have companies attempted to develop bipolar lead/acid batteries for hybrid-electric vehicles [J.L. Arias, J.J. Rowlett, E.D. Drake, Journal of Power Sources, 40 (1993) 63–73.]. Hybrid vehicles have the potential to increase fuel economy by using a primary

Range anxiety reduction in battery-powered vehicles

2016 IEEE Transportation Electrification Conference and Expo (ITEC), 2016
The limited cruising range of Electric vehicles (EVs) and the lack of recharging stations have contributed to what is viewed by potential adopters as range anxiety- contributing to a reserved attitude towards EVs. Within the context of this paper, range anxiety is defined as the concern of the vehicle operator that the EV is running out of energy. Thus,

Advanced batteries for electrically powered underwater vehicles

Proceedings of the 1987 5th International Symposium on Unmanned Untethered Submersible Technology, 2005
Electric propulsion systems have numerous benefits for unmanned, untethered submersibles. However, the low energy density and low specific energy of conventional batteries have made electric systems large and heavy. Four advanced battery technologies, currently under development at Gould, are substantially smaller and lighter than conventional ...

Optimal power sharing between batteries and supercapacitors in electric vehicles

2017 International Conference on Information and Digital Technologies (IDT), 2016
The success of hybrid electrical storage systems which combines batteries and supercapacitors is related to the manner how these devices are managed. In this paper, optimal use of the complementarity between batteries and supercapacitors in electric vehicles is studied.

Power requirements for batteries in hybrid electric vehicles

Journal of Power Sources, 2000
Abstract The operation of batteries in hybrid electric vehicles (HEVs) involves unusual constraints not seen in other applications. This paper reviews the specifications and operational requirements imposed on batteries due to the projected architectures for HEVs as defined by the DOE/PNGV Program.

Review of Battery Systems for Electrically Powered Vehicles

SAE Technical Paper Series, 1968
<div class="htmlview paragraph">Battery performance characteristics for automotive power applications can be described in terms of two parameters, specific power and specific energy. Specific power is related to the speed of vehicles and acceleration. Specific energy is related to range.

High power battery systems for hybrid vehicles

Journal of Power Sources, 2002
Pure electric and hybrid vehicles have differing demands on the battery system of a vehicle. This results in correspondingly different demands on the battery management of a hybrid vehicle. Examples show the differing usage patterns. The consequences for the battery cells and the battery management are discussed.

An Improved Battery Charger for Electric Vehicle with High Power Factor

2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018
The incorporation of active power factor correction (PFC) converter reshapes the line current proportional to the input voltage and reduces the line current harmonics to the recommended IEC 61000-3-2 power quality (PQ) standard for the electric vehicle (EV) battery charger.
