Problems solved by technology

[0010] However, the cooling mechanism of such a secondary battery module has an uneven temperature difference between the unit cells due to possible variations in the amount of cooling air supplied to the space between the unit cells.
[0011] Therefore, it is impossible for this secondary battery module to limit characteristics such as charge-discharge characteristics, and the efficiency of the module is lowered.

Embodiment Construction

[0030] refer to figure 1 and figure 2 , The secondary battery module 100 according to one embodiment of the present invention includes a plurality of unit cells 11 separated from each other.

[0031] Each unit battery 11 includes an electrode assembly in which a separator is interposed between positive and negative electrodes so that the secondary battery can be charged and discharged with a predetermined amount of electricity.

[0032] Each unit cell 11 of this embodiment of the present invention has a substantially prismatic shape.

[0033] Battery separators 15 are installed between the unit cells 11 and at the outermost unit cells 11 to maintain the intervals between the unit cells 11 and to support the sides of each unit cell 11 .

[0034] Each battery separator 15 has channels 17 through which cooler cooling air can circulate. The channel 17 is arranged to have at least one tunnel through the body of the battery separator 15 from edge 17a to edge 17b.

Abstract

The invention discloses a secondary battery module, which comprises a unit cell assembly having a plurality of unit cells spaced apart from each other; a case suitable for accommodating the unit cell assembly; and a communication part installed in the case, the communication part It is suitable for the cooling medium to flow into the case between the plurality of unit cells. The casing includes an inlet for temperature-controlled air to flow into the unit cell assembly, an outlet for air to flow out through the unit cells, and communication members arranged perpendicular to the direction of air inflow and outflow with respect to the inlet and outlet so as to communicate with the unit cells, respectively. The flow channel is connected. The secondary battery module of the present invention can optimize the cooling efficiency of the entire unit battery assembly, thereby further improving charge and discharge efficiency.

Description

technical field [0001] The present invention relates to a secondary battery, and more particularly to a cooling structure for a secondary battery module having a plurality of unit batteries. Background technique [0002] Unlike primary batteries, secondary batteries can be recharged. Low-energy batteries are used in a variety of portable electronic devices, such as in cellular phones, laptop computers, and camcorders. Larger-sized batteries are used for electric motors, such as those in gasoline-electric dual-purpose vehicles. [0003] Secondary batteries may be classified into different types according to the shape of the batteries, for example, prismatic batteries and cylindrical batteries. Secondary batteries can be formed into high-energy secondary battery modules when they are used in machines requiring high energy such as fuel-electric vehicles. [0004] The secondary battery module is formed by connecting a plurality of secondary batteries ("unit cells") in series....
