摘要： A system for controlling a battery to extend a driving mileage is provided. The system supplies a high voltage required to drive a motor by connecting a plurality of batteries in series by turning off a battery switching unit during engaged of an accelerator and balances voltage between the plurality of batteries. A voltage deviation is managed by connecting the plurality of batteries in parallel by turning on the battery switching unit when the accelerator is disengaged. The system includes a plurality of battery modules and a battery switching unit configured to connect the plurality of battery modules in parallel when an accelerator is disengaged and connect the plurality of battery modules in series when the accelerator is engaged. A motor driving unit is configured to receive an output by the battery switching unit when the accelerator is engaged.

摘要： A battery system improving operation reliability of a swelling current interrupt device (CID) is provided. The battery system includes a cooling plate that forms an appearance of a battery in which the swelling CID interrupting a current flow is mounted and includes a swelling aperture formed therein. The swelling aperture induces an expansion of a pouch in which the swelling CID is embedded. Therefore, since the swelling aperture is formed in the cooling plate, improved operation reliability of the swelling CID than a battery system according to related art in which operation reliability was varied based on a thickness of a pouch cell is obtained.
