Abstract: Disclosed herein are an air duct system for a battery of a vehicle and a controlling method for an air duct system for a battery of a vehicle capable of protecting a vehicle passenger from toxic gases and flames introduced into the vehicle due to a fire of a battery by blocking a ventilation hole for cooling the battery when the fire occurs in the battery.

Abstract: A battery pack may include a case including a bottom plate having a surface to which battery modules are mounted; and a cooling block attached to a bottom portion of the bottom plate and being provided with cooling water for removing heat generated by the battery modules.

Abstract: A high voltage battery apparatus for a vehicle is provided. The battery apparatus is installed in a lower portion of the vehicle and includes a plurality of battery modules and a cooling unit that has a plurality of cavities in which the battery modules are inserted and fixed. The cooling unit has a hollow portion through which cooling water flows, thereby cooling the battery modules using the cooling water.

Abstract: A pouch contact type battery cell is provided. The cell includes a gap filling member that is positioned inside a plurality of cell covers that are made of an aluminum material and enclose two pouches and remove a non-contact gap G for preventing electrical insulation breakdown of the pouches and the cell covers in the contacted state with extending portions of the pouches, respectively. A battery module includes a battery cell unit in which the plurality of pouch contact type battery cells are stacked and a battery system includes the battery module. Accordingly, performance of an electric vehicle or a hybrid vehicle is improved due to a reduction in weight based on the reduction in size and volume.
