Hybrid vehicles in the modern era were developed with a strong primary goal to increase fuel efficiency in the North American market. Over the last 15 years, this market has expanded from zero sales to as high as 3% of total US sales. Most recently, the portfolio of competitive offerings with HEV propulsion systems has grown even more to about 30 models on sale today. Some interesting features and attributes have evolved thru this wider array of products giving the customer much more choice of which characteristics to select to match their needs. Ford�s 3rd generation HEV system will be offered for sale this fall. With it, we have continued our focus on the Fuel Efficiency as the driving force for our efforts. The overall process for the system engineering and some of the relevant subsystem and component contributors to the Fuel Efficiency improvement reflected in the 2013 Model Year Fusion and CMAX Hybrids will be presented.

Plug In Charging Systems are mainly responsible for transferring energy from the electric power grid into one or more vehicle energy storage devices (e.g. batteries). A satisfactorily operating Plug in Charging System has the following three key performance characteristics. First, the charge process starts up easily. Second, it completes the charge process within some expected time. Third, it charges efficiently so that excessive amounts of power are not wasted. When a Plug In Charging System malfunction exists and negatively affects one or more of these key performance criteria, it is the responsibility of the OBD monitoring system to identify the fault and notify the customer. The presentation will discuss the key performance characteristics described above and some of the diagnostic strategies used to detect faults. The discussion will also include an overview of MIL illumination and freeze frame storage capabilities.

Evolving the current state of the art Hybrid Technology for vehicles with plug-in capability will yield three significant results, the displacement of petroleum with electricity for transportation, improved efficiency and reduced emissions. As the technology evolves from the Ford Escape Hybrid Plug-In demo fleet, Ford is in the final stages of development of the C-Max Energi, which will be delivered in 2012 as a highly efficient, full purpose vehicle designed to meet customer expectations without compromise.
