This study is in two parts. The first "Thermal study of the battery" provides a mathematical model of the battery, describing air flow pattern and heat transfer of the container, heat generation of the individual monoblocks, ambient temperature and vehicle operation in time; and gives calculation of temperature response in the time domain for various combinations of ambient temperature cycles and vehicle operation. The results show that overheating is unlikely to occur, that overnight garage and indoor charging facilities are preferable in cold climates, and that temperature gradients may cause small differences in lifetime for monoblocks at different positions. The second part is concerned with the "Development of an on board battery charger". Work towards the development of a lightweight charger employing high frequency DC/DC conversion principles is underataken; the charger design is also examined for improvement of battery charge control. Although a complete electrically integrated charger is not achieved, the feasibility of several aspects is demonstrated.
