Development and Implementation of the Visteon Integrated Starter-Alternator System with Ultracapacitors

摘要

This paper presents the design, development and implementation of the Visteon Integrated Starter-Alternator (VISA) system. The unique aspect of the vehicle's power system is that it utilizes the 300 volt ultracapacitors energy storage system, which is smaller and lighter than the 300 volt battery source. The under-hood engine package retains the size of the original Mondeo, a salient mechanical feature of the VISA to engine interface. This paper also presents the development and implementation of traction motor controller, the evolution of control strategy for charging and discharging the energy system and the overall power and mechanical system architecture.
