Abstract

The present invention relates to a current measuring apparatus using a shunt resistor and, more particularly, to a current measuring apparatus using a shunt resistor, which can reduce the volume and price of a battery module and a battery pack by integrating two or more of existing busbar-type components, to each of which one shunt resistor is applied, into one busbar module and measuring the voltage of the battery module through a plurality of shunt resistors included in the integrated busbar module, and which can reliably measure a voltage value by measuring the plurality of shunt resistances through a plurality of measuring units, respectively.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0097245 filed with the Korean Intellectual Property Office on Jul. 29, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a current measuring device using a shunt resistor, in particular to a current measuring device using a shunt resistor, wherein two or more busbars including one shunt resistor are integrated into one busbar module, and the measurement is applied to the integrated busbar The voltage across multiple shunt resistors included in to calculate the voltage of the battery module. Background technique [0004] Secondary batteries having high ease of application according to product groups and electrical characteristics such as high energy density have been widely used in electric drive sources or energy storage systems (ESS) using medium-sized...
