Future Requirements for Alternators 982768

The electrical system of a commercial vehicle is a critical component for reliable vehicle operation. While the demands on today's electrical system have increased dramatically due to higher horsepower engine environments and increased key-off loads, the design of these systems continues to evolve in order to meet these demands. Unfortunately, this design evolution has not kept pace with user expectations for enhanced performance, durability and reduced maintenance of the electrical system. In support of the TMC's S.1 Tomorrow's Truck initiative, this paper offers the following vision of future alternator requirements that will fulfill the expectations of commercial vehicle drivers, maintenance and support personnel. The intent of this vision is that it be used by designers and vehicle manufacturers as a guideline of desirable features for the alternators of tomorrow's truck.
