Thermal management of the battery pack

One of the projects I'm working on this summer is the thermal management of our battery pack during rapid charging. Charging the battery pack in less then 11 minutes generates a lot of heat within the pack. To remove that heat and cool down the cells during rapid charging I've designed a cooling shroud to force air through the closely spaced battery cells inside the pack. To overcome the pressure drop inside the pack we're using three centrifugal blowers.
