Abstract

Disclosed is an insulation resistance measurement device that can carry out failure self-diagnose. In the insulation resistance measurement device having a failure self-diagnosis function according to the present invention, a diagnostic circuit is formed through a first insulation resistance measurement part and a second insulation resistance measurement part that are respectively connected to a positive electrode terminal and a negative terminal of a battery, and a control unit is included that can determine whether there is a failure of the insulation resistance measurement device by using a circuit equation derived from a first and second diagnosis voltage and the diagnostic circuit. According to the present invention, whether there is a failure with an insulation resistance measurement device of a battery can be diagnosed.

Description

Technical field [0001] The present disclosure relates to an insulation resistance measuring device with a fault self-diagnosis function and a fault self-diagnosis method using the device, and more particularly to a battery used in a battery-powered system that requires high voltage for diagnosing Equipment and methods for the failure of the insulation resistance device. [0002] This application claims the priority of Korean Patent Application No. 10-2012-0034907 filed in the Republic of Korea on April 4, 2012 and Korean Patent Application No. 10-2013-0036809 filed on April 4, 2013, which are disclosed Incorporated here by reference. Background technique [0003] Recently, due to the exhaustion of fossil energy and environmental pollution, there is growing interest in electrical products that can be operated with electric energy instead of fossil energy. [0004] Accordingly, with the increasing development and consumption of mobile devices, electric vehicles, hybrid vehicles, powe...
