A battery pack having an active thermal management system for use with a hybrid vehicle is provided. The active thermal management system is self-contained within a housing of the battery pack and includes a thermal channel configured to provide fluid communication between an interior of the housing and an exterior of the housing of the battery pack; a set of thermoelectric devices configured to transfer heat from battery cells of the battery pack to the thermal channel; an insulator arranged between the battery cells and the thermal channel; a device configured to control fluid flow via the thermal channel; and a controller configured to control the device to actively control heat transfer from the interior of the housing to the exterior of the housing of the battery pack to maintain the battery pack at a desired temperature.
