Battery electric vehicles (BEVs) exhibit varying efficiency levels depending on road type characteristics. Key findings show:
1. Optimal Road Types
BEVs perform most efficiently on roads with medium speeds (e.g., arterials and collectors). These include “major collectors,” “minor arterials,” and “other principal arterials,” where steady speeds allow efficient energy use without frequent acceleration/deceleration.
2. High-Speed Roads
Interstates and highways lead to higher energy consumption due to increased aerodynamic drag at elevated speeds. While BEVs maintain a 3.5x efficiency advantage over diesel vehicles even at highway speeds, efficiency still declines compared to lower-speed roads.
3. Low-Speed, Variable Routes
Local roads with frequent stops, speed changes, and idling reduce efficiency due to energy losses from repeated acceleration and limited regenerative braking opportunities.
Additional Factors
- Temperature: Cold weather further reduces efficiency.
- Routing Tools: Apps like Google Maps now offer EV-optimized routes that prioritize energy-efficient roads.
To maximize efficiency, BEV drivers should prioritize routes with moderate speeds and minimal stops.
