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....
