With the rapid development of lithium-ion battery technology, powertrain electrification has been widely applied in vehicles. However, if thermal runaway occurs a pack, venting gas cells will spread and burn rapidly, which poses great threat to safety. In this study, 2D CFD simulation combustion characteristics cell pack is performed, possibility detonation explored. First, numerical model for ...

For the secure usage of battery charging and discharging within electric vehicles, study cell pack equalization technology is essential. Therefore, in this paper, an improved Bidirectional Cuk equalizer (BCEQ) structure based on a variable-domain fuzzy PID (VFPID) control strategy recommended stages. With new topology, only half capacitive inductive components are needed to transfer energy betw...

Innovative vehicle concepts have been developed in the past years automotive sector, including alternative drive systems such as hybrid and battery electric vehicles, so to meet environmental targets cope with increasingly stringent emissions regulations. The preferred hybridizing technology is lithium-ion battery, thanks its high energy density. optimal integration of packs a challenging task ...

The negative impact of the automotive industry on climate change can be tackled by changing from fossil driven vehicles towards battery electric vehicles with no tailpipe emissions. However their adoption mainly depends on the willingness to pay for the extra cost of the traction battery. The goal of this paper is to predict the cost of a battery pack in 2030 when considering two aspects: first...

In manufacturing lithium-ion battery packs for electrical vehicles such as the Chevy Volt, it is critical to create reliable interconnections between battery cells, module-to-module, and module-to-control unit. Such joint connections must possess reliable electrical conductivity and sufficient mechanical strength to ensure battery performance. Ultrasonic metal welding has been adopted for batte...

A unique method has been developed for internally heating hybrid electric vehicle batteries at cold temperatures using high frequency alternating currents (AC). The poor performance of these batteries in cold climates is of major concern because they suffer a huge loss in capacity. Another symptom of this low performance is a dramatic increase in the series resistance of the battery, RB, as the...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper proposes a novel method to find an effective solution for the increasing problems of traffic congestion and environmental pollution through an efficient mode of public transport system. In the proposed topology a combination of dual battery powered plug-in hybrid electric vehicle (PHEV), optimizes the utilization of energy sources dependin...
