The energy consumption of BETs is calculated with a physics-based vehicle model over the drive cycle constructed by Jones et al. , and shown in Figure . The drive cycle was constructed using real-world driving data and features a driving time of 10 hours and 47 minutes over which it covers 600 miles (966 km). The power required at the wheels for a given drive cycle is calculated using Equation 1. The power demand is computed by adding the forces from rolling resistance, aerodynamic drag, gravity and acceleration and multiplying by the velocity of the truck. P wheels (t) = (mgc r cos(θ) + 1 2
