  • Publication number: 20140295226
    Abstract: Provided is a cooling apparatus for a cell assembly type battery configured of a plurality of battery cells. The cooling apparatus is to discharge air introduced into an air inlet to an air outlet via a cooling channel between battery cells to cool a cell assembly type battery, in which a cooling channel covering plate covering a portion of the cooling channel is disposed before or behind the cooling channel so that the cooling channel having the flow of cooling air relatively faster than that in any other cooling channel has an introduction amount of air relatively smaller than that into other cooling channels. Therefore, the cooling efficiency may be excellent and each battery cell may be uniformly cooled without large deviation.

  • Patent number: 7259645
    Abstract: Disclosed is a control switch system for a vehicle, using a jog shuttle, by which a driver can rapidly and correctly select and control operation of a sound system in the vehicle even during driving of the vehicle. Since the control switch system uses simple members such as springs and metal balls, the cost of the vehicle decreases.
