SOC OCV

이번 글에서는 SOC 직접 추종 방법 중의 하나인 OCV에 대해서 적어보도록 하겠습니다. OCV - Open Circuit Voltage Method: OCV - Open Circuit Voltage Method . 우선 Open Circuit에 대해서 설명드리겠습니다. Open circuit이란 선이 끊어져 있는 회로 를 의미합니다 2. SOC (State of Charge, 충전량, 충전상태) SOC는 보통 System On Chip으로 많이 알고 계시지만 배터리에서 사용되면 충전량, 혹은 충전 상태를 의미합니다. 3. OCV (Open Circuit Voltage, 개방회로전압) OCV란 배터리에 전기를 흘려 보내지 않고 그냥 두었을 때 걸리는 전력을 의미합니다 Open-circuit voltage (abbreviated as OCV or VOC ) is the difference of electrical potential between two terminals of a device when there is no external load connected, i.e. the circuit is broken or open There are several ways to get Lithium-Ion State of Charge (SoC) measurement or Depth of Discharge (DoD) of a battery. Main methods are SoC estimation using Open Circuit Voltage Method (OCV) and SoC estimation using Coulomb Counting method. Powertech provides accurate coulomb counter devices for PowerBrick LiFePO

Open circuit voltage(OCV) 을 이용해 SoC 를 측정할 때는 batteryvoltage 가 load 없이 floating 상태여야 한다. 차에 설치된 현재 기생 load(CCV 상태) 는 잘못 읽힐 것이다. 수정사항은 load current 를 포함한 CCV 상태에서 SoC 를 측정할 때 만들어져야 한다 - SOC 추출방법 Ⓐ 단자전압 측정에 기초한 SOC 추정 ⓑ OCV의 측정에 기초한 SOC 추정 ⓒ 전류 적산법에 의한 SOC 추정 ⓓ OCV 모델에 기초한 SOC 추정. Cf. OCV (Open Circuit Voltage) 배터리가 전류가 흐르지 않는 안정화된 상태에서 측정한 전압을 의미합니다. * SOH (State of Health The OCV-SoC curves of NMC cells shown in Figure 1(a) change dramatically as the SoCs drop to 0% and gradually increase between 10% and 100% SoC regions, but for LFP cells shown in Figure 1(b), the OCV-SoC curves change dramatically as the SoCs drop to 0% and rise to 100%, and there are wide flat OCV plateau in the middle SoC regions ting the OCV-SOC data. Instead of measuring the OCV after a long relaxation period at different SOC levels that span the en-tire operating range, the data used for the development of the our OCV model are collected by charging/discharging a LiFePO 4 battery cell at 1 20 C rate. The upper and lower cut-off voltage limits are 3.6 V and 2.1 V. Low-current OCV and Incremental-current OCV tests are two common methods to observe the OCV-SOC relationship, which is an important element of the SOC estimation technique. We conducted an experiment where these two OCV tests are run at three different temperatures and based on which, two SOC estimators are compared and evaluated in terms of tracking accuracy, convergence time, and robustness
