Qhov sib txawv ntawm roj sib thooj muaj peev xwm ntxuav roj ntev tab sis tsis hnyav, uas yog qhov zoo tshaj rau cov khoom siv portable thiab cov chaw tsis muaj ntau av. Lub PCB kuj pab kom muaj kev siv zoo ib yam thaum battery ntxuav roj, tshem roj ib yam txog thaum roj los. Cov battery no muaj qhov sib rov ntev, feem ntau siv tau 500-1000 zaug thaum twv 80% ntawm qhov roj tsha tshaj laug. Qhov kev siv ntau yam no ua rau cov cell protected no zoo rau ntau yam kev siv, ntawm cov khoom siv roj loj txog cov khoom siv roj me. Kev tshawb xyuas teperatures hauv muaj kev pab kom siv nyob rau hauv txhua hom chaw, txhob kom tsis muaj kev puag ncig lossis kev phem. Ntawm qab no, qhov size standard ua rau cov battery no siv tau ntau yam thiab siv tau nrog ntau yam khoom. Qhov sib piv ntawm kev siv zoo, kev pab cuam tseeb meej, thiab siv ntev ua rau cov 18650 protected cell no yog qhov kev le solution zoo rau cov neeg siv thiab cov neeg ua haujlwm.

Tus Tswv Txiaj Pov Ntawm Qhov Ke

Qhov kev tiv thaiv PCB uas tau sib cuam tsham rau hauv daim ntawv 18650 lithium battery yog qhov kev tiv thaiv zoo uas txiav tshiab li ib txoj hlua lithium. Qhov chaw tiv thaiv no muaj feem ntau nyob ib ncig thiab tuaj yeem soj ntsuam cov ntaub ntawv zoo li voltage, current, thiab temperature ib txhis. Qhov chaw no muaj qhov cim tshwj xeej rau kev nres thiab kev tso hluav taws xob, kom tsis txhob tso hluav taws xob ntau lossis tsawg dua qhov tseem ceeb. Thaum sau hluav taws xob, PCB yuav tiv thaiv kev sau ntau hluav taws xob los ntawm kev tshav hluav taws xob thaum lub hlua pib txog qhov voltage siab tshaj plaws, feem ntau yog 4.2V. Txawm li cas los xij, thaum tso hluav taws xob, qhov chaw tiv thaiv yuav tiv thaiv kev tso hluav taws xob tshaj tshwv los ntawm kev tshav hluav taws xob thaum voltage hlawv saum qhov 2.5V. Qhov no yog qhov tseem ceeb heev rau kev tiv thaiv lub hlua kom tsis txhob puag cheeb, thiab kom nws tuaj yeem ua haujlwm ntev. Lub circuit kuj muaj kev tiv thaiv rau short-circuit, tshav hluav taws xob tib moment thaum muaj current loj dua zog, kom tsis txhob muaj kev phem, thiab tiv thaiv tus neeg siv.
