#### Abstract

The purpose of this device is to increase the capacity in batteries for an electric vehicle (EV) which also increases the distance the vehicle will travel. The need for this device is driven by the Electrathon America which is a competition for EVs to travel the furthest distance in an hour. The conditions for the batteries require the temperature to maintain above 80°F but not to reach 125°F. To accomplish the device was made with dimensions and material thermal resistance to offset the heat transfer conditions the at the EV competition. For the size of the device needed and raceway conditions, a R-value of 1 was calculated. The second part of this device was the structure holding the 70 pounds of batteries. The structure would need to withstand the largest dynamic load from stopping. With the existing frame material a cantilevered beam would hold this load and have a safety factor close to 2. In evaluating this device, the temperature range must maintained by the thermal resistance to increase battery capacity by 20 percent.
