System and methods are disclosed incorporating a battery cooling system design that may provide for relatively uniform cooling of an associated battery system. In certain embodiments, a battery cooling system may include a central coolant delivery system configured to circulate liquid coolant through one or more coolant flow channels included in one or more cooling plates. One or more seals may be used to couple the central coolant delivery system to the one or more coolant delivery plates. Embodiments of the disclosed battery cooling system may allow for relatively straightforward manufacturing processes and/or assembly of the cooling system, provide sufficient mechanical strength to support a group of battery packs, reduce the occurrence of liquid coolant leaks, and/or provide for relatively uniform cooling of a group of battery packs.
