The Ford Focus FCEV Hybrid will be produced in limited numbers auto parts over the next few years so that the vehicles can be used in specially set up customer appraisal fleets that will provide Ford with invaluable real-world experience of this technology. Fuel cell vehicles are not expected to be commercially viable before 2010 but Ford will continue to develop fuel cells as the most viable form of zero emissions vehicle technology.
In most Ford driving modes the new 92 hp (68 kW) fuel cell stack provides the sole source of electrical energy for the Ford Focus FCEV powertrain. However, a new design of battery pack can supply an additional 24 hp (18 kW) of propulsion power whenever higher levels of power are needed. This 216-volt unit not only serves as the starter battery for the entire system, but also provides additional thrust during acceleration. In these situations, the Ford Focus FCEV’s energy management system supplies the extra power required from the battery unit.
