Abstract

There is provided a battery pack including a mixed cell and a power device including the same. The mixed cell may include a first cell and a second cell having different electrical characteristics. The electrical characteristics may include at least one of an open circuit voltage characteristic corresponding to a state of charge, an internal resistance, an operation voltage, or a capacity.

Description

technical field [0001] Aspects of the present invention relate to a battery pack including different kinds of cells and an electric device including the battery pack. Background technique [0002] The electric device may include a battery pack for storing energy such as regenerative energy and electric energy generated by an engine when driving a hybrid vehicle. For example, a power device may include a first battery pack and a second battery pack. Electric energy is stored in the first battery pack and the second battery pack, and electric power can be supplied from the first battery pack and the second battery pack to the electrical load. The pack voltage of the first battery pack may be higher than the pack voltage of the second battery pack. [0003] Typically, the first battery pack includes the same kind of battery cells, and the second battery pack also includes the same kind of battery cells. The kind of battery cells forming the first battery pack may be differen...
