Abstract

A battery pack capable of efficiently dissipating heat generated from battery cells by increasing heat exchange efficiency using coolant, and not requiring a separate driver for driving the flow of cooling water by causing the cooling water to flow in a natural, uncompelled manner. In one exemplary embodiment, the battery pack (100) includes a plurality of battery cells (200), a cooling part (300) coupled to the plurality of battery cells (200) and including a plurality of cooling plates including a first plate (310) having a coolant inlet opening (311) and a coolant exhaust opening (312), a second plate (320) having a coolant flow passage, and a third plate (330), wherein the plurality of cooling plates (310, 320, 330) is sequentially arranged adjacent the plurality of battery cells (200). The battery back (100) further comprises a coolant reservoir (380) for supplying coolant to the first plate (310) and for receiving the coolant from the first plate (310).

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2010-0052330, filed on Jun. 3, 2010, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments according to the present invention relate to a battery pack. Background technique [0004] Generally, secondary batteries can be charged and discharged and can be used repeatedly. Small-capacity secondary batteries, each of which includes a single unit cell, are widely used in small portable electronic devices such as mobile phones, notebook computers, cameras, camcorders, and the like. On the other hand, large-capacity secondary batteries, each of which includes a plurality of battery cells, can be used as a motor drive power source, such as hybrid electric vehicles (HEV), electric vehicles (EV), and electric motorcycles, and the like. [0005] A battery pack used as a high-capacity motor dri...
