Abstract
A drain system is described for allowing fluid to drain from a battery pack while maintaining structural integrity of the battery pack. A frame of the battery pack is comprised of several retaining members in which valves are disposed to allow fluid to exit the battery pack. The valves are positioned such that forces normally experienced while driving a vehicle, such as acceleration, deceleration, and turning forces, cause the fluid to flow toward and through the valves.
