• Urban transit agencies across the United States operate several types of services, inluding paratransit operations and fixed route fleets. The paratransit service operations are unique, since they do not run fixed routes and have relatively long passenger stops. During these stops, passengers onboard the vehicle must be kept comfortable, requiring operation of the heating, ventilation, and air conditioning (HVAC). In a conventional bus configuration, the engine must be idling to power the HVAC compressor and other accessories. Thus, the engine idle time in a paratransit fleet is a substantial portion of the daily operation. This paper describes a research program with goals of lowering paratransit bus emissions, improving fuel economy, and reducing engine idle time. The program concept is electrification of the bus accessories using a high voltage battery and alternator system. With the vehicle engine running, the high voltage battery is charged via the engine driven high voltage alternator. During vehicle stops, the engine can be turned off to reduce emissions, increase fuel economy, and reduce idle time while still having HVAC for passenger comfort powered from the high voltage battery. This paper will describe the modeling, design, installation, and testing phases of the vehicles.
