Abstract
Lithium-ion batteries have led features over other types of batteries which are high density, high power density, long life, and environmental friendliness. U.S Advanced Battery Consortium also agrees to state that Li-ion batteries are the most suitable for long-term advanced battery technologies. They are related significantly with vibration, temperature, and pressure . Vibrational of the battery pack must be circumvented from the natural frequency of vehicle suspension system and sprung mass from 0 to 7 Hz, vehicle powertrain,i.e driveline, and gearbox, from 7 to 20 Hz, and the vehicle chassis system from 20 to 40 Hz. Battery pack’s structure through positioning elevation to avoid battery pack damage by the rear impact is discussed in US Patent 7070015. About 288 Li-ion pouch cells of Chevrolet Volt battery pack for 70 % of the battery mass and around 55 % of the pack volume are located in a T-shaped steel vertical tray. The battery pack is stranded over the chassis center under the passenger seats. With this thesis, several designs of lithium-ion battery packing will be examined to select optimum model battery packing which robust, safe in which following the battery packing standards.
