A unique method has been developed for internally heating hybrid electric vehicle (HEV) batteries at cold temperatures using alternating current (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(More)
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(More)
A technique has been developed to estimate the internal battery temperature (T bat) of secondary batteries by measuring the series battery resistance (R B) at cold ambient temperatures. Tests were performed on both lead-acid and nickel metal hydride batteries at different cold temperatures to obtain useful plots of R B versus T bat. R B was measured by(More)
A new xylose fermenting yeast was isolated from over-ripe banana by enrichment in xylose-containing medium. The phylogenetic analysis of ITS1-5.8S-ITS2 region sequences of ribosomal RNA of isolate BY2 revealed that it shows affiliation to genus Pichia and clades with Pichia caribbica. In batch fermentation, Pichia strain BY2 fermented xylose, producing 15 g(More)
