Patent ID: 8623538

Claim:
An automotive battery pack assembly comprising: a battery pack comprising a heat generating source with two or more individual regions, each individual region of said two or more individual regions has a particular temperature regime, said battery pack configured to provide motive power to a vehicular platform; and a thermal management system in thermal communication with said heat-generating source within said battery pack, said thermal management system comprising: a cooling plate placed in thermal communication with said heat-generating source of said battery pack and comprising a plurality of individual channels, wherein each individual channel of said plurality of individual channel has two or more tailored microencapsulated phase change materials placed therein, each tailored microencapsulated phase change material corresponds with said particular temperature regime of each individual region; a fluid conduit configured such that at least a portion thereof is placed in thermal communication with a heat-generating portion of said battery pack; and a fluid medium containing at least one microencapsulated phase change material therein, said fluid medium disposable within said fluid conduit such that an exchange of heat between said heat-generating portion of said battery pack and said at least one microencapsulated phase change material takes place during said thermal communication; wherein said two or more tailored microencapsulated phase change material comprises a plurality of tailored microencapsulated phase change materials one of which is configured to exhibit phase change at a first temperature corresponding to a first temperature regime of a first region of the battery pack and another of which is configured to exhibit phase change at a second temperature that is higher than said first temperature, the second temperature corresponding to a second temperature regime of a second region of the battery pack.
