Problems solved by technology

[0008] However, when it is desired to use the technology of the above-mentioned prior art, it is necessary to change the insulation resistance measurement circuit already provided in the existing battery, so it is difficult to use it practically.
Not only that, but in the existing literature, each switch needs to be turned on and off in various combinations when performing the measurement, so the steps are complicated, and the operation load, calculation load, etc. will rise unnecessarily

Embodiment Construction

[0046] Next, the method of measuring the insulation resistance of the present invention having the above-mentioned structure will be described in detail with reference to the drawings.

[0047] First, an insulation resistance measurement circuit for an insulation resistance measurement method of sensing insulation breakdown of a battery will be briefly described. Such as figure 1 As shown, the insulation resistance measurement circuit includes: a node P on the positive side, located on the positive side of the battery; a node N on the negative side, located on the negative side of the battery; a node G on the ground side, which is grounded; an insulation measuring part on the positive side , disposed between the positive-side node P and the ground-side node G; the negative-side insulation measurement unit, disposed between the negative-side node N and the ground-side node G. Voltage signals are respectively output from the positive side insulation measurement part and the neg...

Abstract

The present invention provides an insulation resistance measurement method capable of accurately measuring an insulation resistance even though insulation breakdown occurs in both ends of a battery byimproving an insulation resistance measurement algorithm in spite of utilizing an existing insulation resistance measurement circuit as it is in measuring insulation breakdown of the battery.

Description

technical field [0001] The present invention relates to an insulation resistance measurement method and a measurement device, and in more detail, relates to an insulation resistance measurement method and a measurement device. When measuring the insulation breakdown of a battery, the insulation resistance measurement circuit used in the prior art is used as usual. In this case, by improving the insulation resistance measurement algorithm, the insulation resistance can be accurately measured even when the insulation at both ends of the battery is broken. Background technique [0002] Circuits included in most electronic products are basically insulated from the outside in order to prevent accidents caused by electric leakage, or to additionally infiltrate unnecessary noise from the outside. However, in the actual product use site, harsh environmental conditions such as moisture permeating around the product often occur. In particular, when moisture exists near the power suppl...
