Abstract

A micro-channel cooling fin for a battery module and battery is provided. The cooling fin includes a metal plate assembly that defines a plurality of cooling channels therein. The metal plate assembly includes an inlet section for introducing a coolant into the plurality of cooling channels and an outlet section from which the coolant exits the plurality of cooling channels. Each channel has an output temperature and an input temperature such that the output temperature minus the input temperature for each cooling channel is within a predetermined amount.

Description

technical field [0001] In at least one aspect, the present invention relates to cooling systems for battery modules, and in particular to cooling fins for use in such cooling systems. Background technique [0002] Large-capacity rechargeable batteries are currently being researched for use in electric vehicles. The ultimate viability of electric vehicles depends largely on reducing associated costs. Reducing the costs of battery components is particularly important in this regard. [0003] Lithium-ion batteries are an important type of battery technology. Most battery packs, including lithium-ion battery packs, have multiple individual electrochemical cells. Typically, such an electrochemical cell includes an anode, a cathode, and a separator between the anode and cathode. Typically, the anode consists of a metal sheet or foil (usually copper metal) coated with a layer of graphite. Similarly, a cathode typically comprises a metal sheet or foil (usually aluminum metal) o...
