•  The Junior ROTC members, all of whom had no

experience driving electric go-karts, were divided into six

groups.

•

  Each group was assigned to one electric go-kart.•  The members of a group rotated among driving a go- kart,

collecting information, serving as pit workers, and serving as

members of the first-aid crew.

•  The information collected were

  time taken for each of seven laps (twice)

  number of years driving internal combustion vehicles

  number of watt-hours used for each of seven laps

  number of amp-hours used for each of seven laps

•  This year, leading technical universities in Indiana

established a program to prepare the workforce needed to

design, manufacture, and maintain advanced electric

vehicles.

•  To achieve this aim, an Electric Grand Prix go-kart race

was developed to excite young people to commit to a career

in electric vehicle technology, ensuring the development of

the next generation of electric vehicles.

•  Fifty Junior ROTC members were invited to the go-kartrace to learn about electric vehicles and participate in a

study on how experience in driving internal combustion

vehicles and lack of experience in driving go-karts affect

energy usage/efficiency.

INTRODUCTION

METHODOLOGY

•  First, the average of the two measured times was taken.

•  Next, the amount of amp-hours used by each driver was

compared with the time it took each driver to complete the

race and the number of years of the driver’s experience with

internal combustion vehicles.

•  The comparisons provided information on trends or the

lack of trends in how inexperienced drivers use electric

vehicles.

DATA ANALYSIS

•  The analysis showed that the maximum energy usage of

inexperienced drivers was 44.625 W-H/lap.

•  And that the average energy usage of inexperienced

drivers was 30.00 W-H/lap.

•  The analysis also showed that the minimum energy usage

of inexperienced drivers was 19.211 W-H/lap.

•  Also, the analysis showed that, given a driver’s

inexperience with electric vehicles, there is no significant

connection between a driver’s experience with internal

combustion vehicles and his/her ability to drive electricvehicles efficiently.

•  The information on minimum, maximum, and average

energy usage will help us design batteries for future races

 because it gives an estimation of the amount of energy, and

hence the battery capacity, required for each lap in a race.

•  The next experiment in this study will determine, for

experienced drivers, the relationships among the factors that

affect energy efficiency in electric vehicles.

•  We will also develop a race strategy that helps driversknow how to conserve energy and maximize time.

•  The broader goal of the research project is to increase

energy-efficiency in future electric vehicles.
