1. Number of variables: 7


2. Missing data codes:
        Blank cells
The data contained in the repository is the raw data with noise and low resolution. Also, there are missing values. To do simulation discussed in the paper, preprocessing should be performed according to section V of the paper.


3. Variable List            

    A. Name: Time(s)
       Description: Time elapsed, in seconds


    B. Name: Distance(km)
       Description: Distance traveled, in km

    C. Name: Velocity(km/h)
       Description: Velocity of car

    D. Name: Engine_on_off
       Description: "FALSE" indicates that the engine was off
                    "TRUE" indicates that the engine was on

    E. Name: SOC(%)
       Description: State of Charge
                    How much energy remained in the battery, between 0 and 100%

    F. Name: SOC_ref(%)
       Description: The expected state of charge at this time step, given current actual distance        traveled and the value of Lset   

    G. Name: Lset(km)
       Description: The Lset controls how frequently the engine is on to charge the battery to           aid the actual SOC to meet the SOC_ref
