Abstract

본 발명은 전지 개별전압 측정장치에 관한 것으로서, n개의 개별 전지와, 개별 전지의 전압을 측정하는 n개의 전압측정모듈과, n개의 전압측정모듈에 온／오프 제어신호, 기준전원, 어드레스와 클럭을 공급하고, 전압측정모듈에서 측정된 n개의 개별 전지의 전압을 더하여 전체 전지 전압을 계산하고, 일정 전압 이하가 된 불량전지의 번호를 표시하는 메인시스템으로 구성된다. 따라서, 개별 전지의 전압을 측정함으로써 개별 전지의 이상유무를 확인하여 이상이 발생된 전지의 번호를 실시간으로 표시할 수 있기 때문에 전체 전지 전압을 측정하지 않아도 이상이 발생된 전지를 찾아서 즉시 교체해 줄 수 있고, 배선 가닥의 수를 줄여 노이즈의 영향을 감소시킨다.The present invention relates to an individual battery voltage measuring apparatus, comprising n individual batteries, n voltage measuring modules for measuring voltages of individual batteries, and n voltage measuring modules with on / off control signals, reference power supplies, addresses, and clocks. It is composed of a main system that supplies the power supply, calculates the total battery voltage by adding the voltages of the n individual cells measured in the voltage measuring module, and displays the number of the defective battery which is below a certain voltage. Therefore, by checking the voltage of individual batteries, you can check the status of individual batteries and display the number of batteries in real time, so you can find and replace the batteries immediately without measuring the total battery voltage. In addition, the number of wiring strands is reduced to reduce the influence of noise.
