Abstract

- Lithium ion batteries are an important type of battery technology. Most battery assemblies, including lithium ion battery assemblies, include a plurality of individual electrochemical cells. Typically, such electrochemical cells include an anode and a cathode. Typically, the anode includes a metal sheet or foil (usually copper metal) over-coated with a graphitic layer. Similarly, the cathode usually includes a metal sheet or foil (usually aluminum metal) over-coated with a lithium-containing layer. Finally, electrochemical cells include an electrolyte which is interposed between the anode and the cathode. Terminals allow the generated electricity to be used in an external circuit. Electrochemical cells produce electricity via an electrochemical reaction.
- For high power application, a plurality of battery cells are utilized and assembled into a battery module. Moreover, such battery modules are assembled into battery packs which include a cooling system and related electronics for operating the batteries. The cooling systems typically include a plurality of metallic (e.g., copper and/or aluminum) cooling fins interspersed between the battery cells. It turns out that the assembly of such battery modules is fairly difficult with respect to aligning the cooling fins and the battery cells. Moreover, other prior art cooling systems utilize air coolant that impact a plurality of dimples to increase air flow speed.
- Accordingly, there is a need for improved battery pact cooling systems.
- The present invention solves one or more problems of the prior art by providing in at least one embodiment, a cooling system for a battery pack. The cooling system includes a fluid source for providing cooling fluid and a turbulator in which the cooling fluid flows along an average flow direction. The turbulator includes a first support member, a second support member, a third support member, a first plurality of rods positioned between the first support member and the second support member, and a second plurality of rods positioned between the second and the third support members. The first plurality of rods is offset from the second plurality of rods in a direction perpendicular to the average flow direction. Finally, the first plurality of rods and the second plurality of rods disrupt air flow from the fluid source into non-laminar flow. Advantageously, the cooling system and turbulator of the present embodiment, increase air speed and promote the uniform heat balance between the opposite walls in the channel of the turbulator in which cooling fluid flows.
- In another embodiment, a battery pack integrating the cooling system set forth above is provided. The battery pack includes a plurality of battery cells and a plurality of turbulators disposed between adjacent battery cells in the plurality of battery cells in which cooling fluid flows along an average flow direction. Each turbulator includes a first support member, a second support member, a third support member, a first plurality of rods positioned between the first support member and the second support member, and a second plurality of rods positioned between the second and the third support members. The first plurality of rods is offset from the second plurality of rods in a direction perpendicular to the average flow direction. Finally, the first plurality of rods and the second plurality of rods disrupt fluid flow from the fluid source into non-laminar flow.
