Abstract
Systems are disclosed for battery modules/systems with cooling systems. In accordance with disclosed embodiments, the cooling system may be disposed against an external surface of a housing of the battery system. The cooling system may utilize air as a coolant to remove heat generated by cells within the battery module, to prevent the cells from aging prematurely. Embodiments of the cooling system may include manifolds, channels, fins, or a combination thereof, which may route the cooling air along the surface of the battery module housing. Such features may create an isothermal temperature distribution within the battery system.
Claims17
A battery system having a cooling system, wherein the cooling system comprises:
- a cover plate formed from a conductive material;
- a plurality of channels disposed within the cover plate;
- a pair of inlet manifolds configured to convey a coolant into the plurality of channels of the cooling system, wherein a first inlet manifold of the pair of inlet manifolds extends along a first side of the cover plate, wherein a second inlet manifold of the pair of inlet manifolds extends along a second side of the cover plate, and wherein the plurality of channels extends between the first and second sides of the cover plate, wherein the plurality of channels extends over the first inlet manifold and the second inlet manifold, such that an inlet aperture into each respective channel of the plurality of channels opens downwardly into, and fluidly couples the respective channel to, either the first inlet manifold or the second inlet manifold;
- and
- a pair of outlet manifolds configured to convey the coolant out of the plurality of channels.
A system, comprising:
- a battery system, comprising:
- a housing configured to enclose the battery system and formed from a conductive material;
- and
- a plurality of battery modules, each battery module of the plurality of battery modules having a plurality of electrochemical cells;
- and
- a cooling system disposed on an outside of the housing of the battery system, comprising:
