Abstract
A battery pack thermal management system for use in an electric car. The battery pack thermal management system includes a plurality of thermistors connected to a plurality of cells of a battery pack. A battery monitor board is connected to the thermistors. The system also includes a manifold and a plurality of cooling tubes connected to the manifold. A tube seal plug is arranged over an end of the cooling tube and an end fitting is arranged on an end of the cooling tube. The thermal management system will cool the battery pack to predetermined temperatures to increase the longevity of the battery pack within the electric vehicle.
