Title: Power Consumption Characterization, Modeling and Estimation of
Electric Vehicles

Abstract:
Rapid electric vehicle (EV) penetration gives a threatening challenge in
electric energy generation. An 1,814 kg curb weight full electric vehicle
driving 18,129 km/year consumes electricity energy equivalent to 74% of the
total residential electricity use per person in the US. This implies that
27% more nationwide electricity generation is needed when 70% of passenger
vehicles are replaced with EVs.

This talk introduces the first step toward systematic EV design-time and
runtime optimization. We develop instantaneous power consumption modeling of
an EV by the curb weights, speed, acceleration, road slope, passenger and
cargo weights, motor capacity, and so on, as a battery discharge model. The
model also considers the onboard charger, regenerative braking and so on, as
a battery charge model. To insure model fidelity, we fabricate a lightweight
custom EV, perform extensive measurement, and derive model coefficients
using multivariable regression analysis. We estimate the EV instantaneous
power consumption of a given speed and route profiles and verify the
estimation fidelity with a real test run data.
