Abstract

An insulation resistance measurement device having a malfunction self-diagnosis function, and a method for self-diagnosing malfunction by using same are disclosed. The insulation resistance measurement device having the malfunction self-diagnosis function determines whether the insulation resistance measurement device is malfunctioning by means of first and second insulation detection voltages detected when a diagnostic unit is disconnected (insulation resistance measurement mode), and first and second insulation detection voltages detected when the diagnostic unit is connected (malfunction self-diagnosis mode). According to the insulation resistance measurement device and the method, self-diagnosis of whether a malfunction exists is possible by means of an inherent functionality of the insulation resistance measurement device capable of measuring insulation resistance.

Description

technical field [0001] The present disclosure relates to an insulation resistance measuring apparatus and method, and more particularly, to an insulation resistance for diagnosing a malfunction of a device that can measure the insulation resistance of a battery employed by a battery powered system requiring a high voltage, such as an electric vehicle or a hybrid electric vehicle Measuring equipment and a fault self-diagnosis method using the insulation resistance measuring equipment. [0002] This application claims priority to Korean Patent Application No. 10-2012-0030942 filed on March 27, 2012 and Korean Patent Application No. 10-2013-0031933 filed on March 26, 2013, the disclosures of which are hereby incorporated by reference into this article. Background technique [0003] In recent years, due to the depletion of fossil energy and environmental pollution, there has been increasing interest in electrical products that may operate using electrical energy instead of foss...
