摘要：
This
paper presents a RAPS, namely the regenerative auxiliary power system, for the
vehicle with special accessory power systems. Taking city buses and delivery
trucks as examples, service vehicles keep engines idling to power their
auxiliary devices (e.g., refrigeration systems and hydraulic pumps). The
potential fuel savings brought on by the electrification of these auxiliary
systems are first quantitatively analyzed over a typical drive cycle for a
delivery truck. The RAPS is then designed, and its components are sized in
accordance with the objectives of compactness and cost-effectiveness. By
introducing the proposed RAPS into a conventional delivery truck with an
internal combustion engine, the powertrain can be treated as a hybrid because
of adding an extra battery. As a result, to pursue a high overall efficiency, a
holistic controller is presented for determining how and when to recharge the
battery while minimizing the auxiliary system’s power consumption. More
importantly, the proposed RAPS saves about 7% fuel when compared with
consumption by conventional service vehicles.
