Abstract
A battery pack includes a number of battery modules, a case, a circulation unit and a control unit. The case accommodates the plurality of battery modules therein. The circulation unit is positioned in the case so as to circulate heat generated from the plurality of battery modules. The control unit selects one or more of the number of battery modules and operates the circulation unit using power of the selected battery modules. Accordingly, the temperature equilibrium of the battery pack is implemented by conducting heat from a high-temperature battery module to a low-temperature battery module, so that it is possible to decrease the degree of deterioration and to extend the lifetime of the battery pack.
