Quantifying variability in detailed energy useage on repeated trips in the chevrolet volt

There is a large quantity of data available on the CAN bus of the Chevrolet Volt that can be obtained through the OBD2 connectors on both the passenger and driver side of the vehicle. Although much of this is not available on the console of the vehicle to passengers, it can be logged and collected to analyse various vehicle performance measures and behaviours as well as charging characteristics. A set of pertinent data has been collected simultaneously for approximately 40 vehicle parameters for numerous trips and charging events for the 2012 Chevrolet Volt. The average energy useage for each trip and the trip length have been summarized to illustrate that for the same trip there are a number of variables that can introduce significant variability in the amount of energy used by the vehicle. Individual trips were logged at a sample rate of ~1000 Hz and as many variables as could be controlled were kept constant to illustrate and compare the effects of driving behaviour on the energy useage. Driving at several different constant speeds for the entire trip was compared for total energy useage. It is noted that there is a significant increase in energy usage for a particular trip travelled at a faster speed.
