The trend in FCIM vehicles continues toward variety, complexity, immensity, and unique function. Vehicle, engine, and component manufacturers work together in application of special generators, cranking motors, batteries, and wiring to meet the needs of the engine, vehicle, and operational mode.
Approaches to applying electrical component systems designed to function synergistically on the vehicle are now being investigated. Experimental studies on line-haul highway tractors, using new developments combining components, hardware, instrumentation, and electrical diagnostics, show promise of improvement of generator, cranking motor, and battery life and service. Principles applied in the systems approach should be applicable in FCIM areas.
