The use of batteries in hybrid vehicles
Résumé
This paper details the main functions of hybrid drivelines according to their architecture together with the corresponding characteristics and constraints of the batteries. Battery behavior for different types of hybrid drivelines are presented through experiments conducted on the first marketed hybrid vehicles. The problem of battery ageing is accessed through battery failure modes and testing procedures. The battery depth of discharge (DoD) is highlighted as an important factor in battery ageing, if not properly controlled. Consequently a DoD evaluation method is presented. Experiments and firsts results on a VRLA battery are described.
