Problems solved by technology

[0009] However, in the related art, since high current flows through connectors applied to high-capacity and high-current battery packs, the connectors are easily heated to high temperatures due to resistance
Therefore, the high-temperature connector may damage the printed circuit board, which is an internal part of the battery pack, or the battery pack case that it touches may melt, and the user is likely to be burned when he or she holds the battery pack with his or her hands.

Abstract

Disclosed is a connector with enhanced heat dissipation efficiency and convenience of use. The connector, according to the present invention, for accomplishing the purpose comprises: a mounting unit electrically connected to a printed circuit board of a battery management unit for managing the voltage of a plurality of battery cells; and a connection unit which includes two or more connection terminals that come in contact with a counterpart connection terminal, and which has an uneven structure formed on the outer surface of the connection terminals.

Description

technical field [0001] The present disclosure relates to a connector, a battery management unit, and a battery pack, and more particularly, to a connector with improved heat dissipation efficiency and ease of use. [0002] This application claims priority from Korean Patent Application No. 10-2019-0105128 filed in Korea on Aug. 27, 2019, the disclosure of which is incorporated herein by reference. Background technique [0003] Recently, secondary batteries capable of charging and discharging have been widely used as energy sources for wireless mobile devices. In addition, secondary batteries are attracting attention as power sources of electric vehicles (EVs) and hybrid electric vehicles (HEVs) proposed as solutions to air pollution such as existing gasoline vehicles and diesel vehicles using fossil fuels. [0004] In small mobile devices, one or two or three battery cells are used per device, while in medium and large devices such as automobiles, due to the need for high p...
