Within the framework of its development strategy in automotive applications, THOMSON-CSF, has decided to regard an engagement in the area of alternative transportation means as very promising. It has thus initiated the development of various components for electric vehicles. This article will concentrate on the presentation of a drive unit, which has been designed and developed by AUXILEC, a subsidiary of THOMSON-CSF. The drive unit consists of a separately excited synchronous machine with related power electronics and control electronics. Motor and electronics have been developed as an integrated unit for application in small and medium sized personal cars. The drive unit has remarkable performance characteristics such as high efficiency, a large field weakening range and maximum protection against dust and water. In comparison to other solutions such as induction drives or permanent magnet drives it offers advantages concerning requirements for power electronics and computation capacity. The article will also describe other components developed by THOMSON-CSF such as an on-board charger, a static converter and a battery monitoring system. A demonstration vehicle has been equipped with the drive unit and with some of these components. Its characteristics and performance will be resumed at the end of this paper.
