Energy comparison calculations
This comparison is for energy consumed only and does not consider things like the cost of a person required to operate a UPS truck as well as well as leave packages at doors. The fact that a UPS truck is much larger and heavier than the BEAM Transporter is considered in the calculations as aerodynamic drag, frontal area and larger empty weight.
velocity profile
- To begin, a simulated velocity profile of a delivery vehicle was obtained through ResearchGate. This velocity profile was developed in a study of urban freight transport and along with a the following information for an average UPS 'Brown' truck, energy calculations can be made:
- Vehicle empty weight: 16,000 lbs.
- Average distance traveled per day: 50 mi.
- Average delivery stops per day: 150
- Coefficient of rolling friction: 0.01
- Frontal surface area: 0.456 m2
- Drag Coefficient: 0.46
Equations used
To the left are the equations used in calculating the energy require for a standard UPS "Brown" truck to make 150 deliveries over 50 miles and comparing that to the energy required by BEAM Transporter to do the same task.
