3.1. ADVISOR 2002 Model of Electric Buses on Unitrans Route ADVISOR 2002 (ADVISOR) simulation software models vehicle emissions and driving capabilities over specified routes and can be applied to buses. This model calculates the total distance travelled, the gasoline equivalent fuel economy (mpg), and the energy use breakdown of mechanical systems in the vehicle [11]. As noted, the XE40 is modeled to determine whether a typical EB is capable of completing the average Unitrans route distance on one charge. The following assumptions are used as inputs to ADVISOR: • Lithium ion, 300 kW capacity battery. • 80% battery round trip efficiency. • Gross weight is 15,454 kg. • Transmission: 85% efficiency. • “Heavy” wheel/axle and accessory. • Max power is 160 kW MC_AC75 motor option, 92% efficiency. • Battery is discharged to manufactures recommended minimum capacity (20%).
