Abstract

An apparatus for calculating insulation resistance according to one embodiment of the present invention comprises: a switching unit comprising a first switch and a second switch which are controlled independently of each other; a first protective resistor and a first reference resistor which are connected in series between a positive terminal and ground of a battery when the first switch is turnedon; a second protective resistor and a second reference resistor which are connected in series between a negative terminal and the ground of the battery when the second switch is turned on; a voltagemeasuring unit configured to measure a first detection voltage applied to the first reference resistor, and a second detection voltage applied to the second reference resistor; and a processor configured to determine whether a measurement error has occurred in measured values of the first detection voltage and measured values of the second detection voltage.

Description

technical field [0001] This application claims priority from Korean Patent Application No. 10-2016-0152758 filed in Korea on Nov. 16, 2016, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to an apparatus and method for calculating insulation resistance, and more particularly, to an apparatus and method for quickly and accurately calculating insulation resistance of a battery in consideration of parasitic capacitance of the battery. Background technique [0003] Recently, the demand for portable electronic products such as laptop computers, video cameras, and mobile phones has increased dramatically, and with the widespread development of electric vehicles, energy storage devices, robots, and satellites, research is being conducted on high-performance secondary batteries that can be repeatedly charged. Many studies. [0004] At present, secondary batteries available on the market include nickel-cadmium batteries, nickel-hy...
