As hybrid and electric vehicles continue to evolve there is a need for better battery
thermal management systems (BTMS), which maintain uniformity of operating
temperature of the batteries in the vehicles. This thesis investigates the use of an
indirect liquid cooled system, which can be applied to hybrid and electric vehicles.
The design is modeled as part of the UOIT EcoCAR. The predominant focus of this
indirect liquid cooled system is the entropy generation in each of the components
within the system, as well as a total system analysis. Four main components of the
system are the battery module, heat exchanger, pump, and throttle. The battery
module coolant tubes and the entire heat exchanger model are developed. Various
parameters are changed in each component, leading to a decrease in entropy
generation depending on the variable changed. Of the four components identified, the
heat exchanger produced the majority of entropy generation, which leads to an overall
increase in system entropy generation. There are many factors to consider when
designing a liquid cooled BTMS. The new model shows a unique ability to improve
system performance by reducing the entropy generation in the BTMS. / UOIT
