Ph.D. Thesis Rechargeable lithium battery energy storage systems for vehicular applications PhD. Candidate: Tarun Huria UNIVERSITÀ DI PISA Engineering School “Leonardo da Vinci”

Abstract Batteries are used on-board vehicles for broadly two applications – starting-lighting-ignition (SLI) and vehicle traction. This thesis examines the suitability of the rechargeable lithium battery for both these applications, and develops algorithms for runtime prediction of the remaining battery charge. The largest market-share of rechargeable batteries is for the SLI application. Lead-acid batteries rule this market presently, although a handful of lithium SLI batteries have recently appeared on the market. The practicality of different lithium battery chemistries has been evaluated for this application over wide-ranging criteria and it has been found that the batteries based on lithium iron phosphate and lithium titanate oxide chemistries commercially available in the market are the most suitable. Lithium SLI batteries would require a higher initial cost and additional electronic hardware in the form of battery management and thermal management systems, but would last the life-time of the vehicle. In fact, with the decrease in the cost of lithium SLI batteries with higher volumes, over the life-time of the vehicle, the total costs of the existing lead-acid battery and the lithium battery would be about the same.
