The invention provides for a high occupancy or heavy-duty vehicle with a battery propulsion power source, which may include lithium titanate batteries. The vehicle may be all-battery or may be a hybrid, and may have a composite body. The vehicle battery system may be housed within the floor of the vehicle and may have different groupings and arrangements. 1a lithium titanate battery power source, wherein the lithium titanate battery power source includes a plurality of battery packs and is housed within a floor structure of the heavy-duty vehicle such that individual battery packs are individually mounted into cavities within the floor structure.. A heavy-duty vehicle comprising: This application is a continuation of U.S. patent application Ser. No. 12/459,074, filed Jun. 26, 2009, which claims the benefit of U.S. Provisional Application No. 61/076,480, filed Jun. 27, 2008, which applications are entirely incorporated herein by reference.This invention was made with the support of the United States government under the National Fuel Cell Bus program, Project ID numbers GA-04-7001, GA-04-7002 by the Federal Transit Administration (FTA).In recent years, hybrid and electric vehicles, which are provided with a battery, have been proposed, and some of them have been put into practice, to effectively use energy, in particular, regenerative energy as environmental measures. Typically, secondary batteries, which have been put to into practice and installed in vehicles so far, include, for example, lead storage batteries, nickel metal hydride batteries, or high powered lithium ion batteries.The use of such batteries provide many challenges such as thermal degradation, or the requirement of significant volumes or space due to low capacity. Such batteries may be heavy, which can lead to decreased performance of vehicles. Furthermore, the active materials of the electrodes are low in the rate of occluding and discharging ions, and hence efficient charging cannot be achieved ...
