Comparison of Electric Vehicle’s Energy Consumption Factors for Different Road Types

Table 3

Energy consumption factor models.

Road type	Calculation equation
Express way	EF=0.247+1.520/𝑣−0.004𝑣+2.992×10^−5𝑣^2
Arterial road	EF=−0.179+0.004𝑣+5.492/𝑣
Secondary road	EF=0.21−0.001𝑣+1.531/𝑣
Branch	EF=0.208−0.002𝑣+1.553/𝑣

Note: EF is the energy consumption factor, kwh/km, and 𝑣 is the average travel speed, km/h.
