Abstract

The present invention relates to an apparatus and method for detecting a defect in a battery pack and, more specifically, to an apparatus and method for detecting a defect in a capacitor provided inside a battery pack. According to the present invention, a noise signal is used to detect a defect in a capacitor, and thus there is an advantage in that the defect in the capacitor inside the assembled battery pack can be conveniently detected. Also, the present invention includes a compact circuit structure for noise signal output, noise signal filtering, and voltage measurement, and therefore has an advantage in that the cost of detecting defects in a capacitor can be reduced.

Description

technical field [0001] This application claims the benefit of Korean Patent Application No. 10-2019-0063998 filed in Korea on May 30, 2019, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to an apparatus and method for detecting a defect of a battery pack, and more particularly, to an apparatus and method for detecting a defect of a capacitor provided in a battery pack. Background technique [0003] Recently, the demand for portable electronic products such as notebook computers, video cameras, and portable phones has increased dramatically, and electric vehicles, energy storage batteries, robots, artificial satellites, and the like have been urgently developed. Thus, high-performance batteries that allow repeated charging and discharging are being actively researched. [0004] Currently commercially available batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, lithium batter...
