Lub ntsiab lus ntawm Battery Protection Board

Kev tiv thaiv kev ua haujlwm ntawm lithium roj teeb feem ntau ua tiav los ntawm kev tiv thaiv Circuit Court board thiab cov khoom siv tam sim no xws li PTC lossis TCO. Lub rooj tiv thaiv kev tiv thaiv yog tsim los ntawm cov hluav taws xob hluav taws xob, uas tuaj yeem saib xyuas qhov hluav taws xob thiab them nqi thiab tawm ntawm cov roj teeb ntawm txhua lub sijhawm hauv ib puag ncig ntawm -40 degree rau ntxiv rau 85 degree . Tam sim no ntawm lub voj tuaj yeem tswj tau qhov kev tawm ntawm lub voj tam sim no; PTC lossis TCO tuaj yeem tiv thaiv kev puas tsuaj rau lub roj teeb hauv qhov kub thiab txias.

Lub rooj tiv thaiv kev tiv thaiv feem ntau suav nrog kev tswj IC, MOS hloov, precision resistor thiab auxiliary ntaus ntawv NTC, ID nco, PCB, thiab lwm yam. Ntawm lawv, cov tswj IC tswj MOS hloov mus qhib thaum txhua yam zoo li qub, kom lub xov tooj sib txuas lus nrog lub sab nraud Circuit Court, thiab thaum lub xov tooj ntawm tes los yog lub voj tam sim no tshaj li qhov teev tseg, nws tam sim ntawd (ntaus milliseconds) tswj lub MOS hloov mus tua, Tiv thaiv kev nyab xeeb ntawm cov hlwb.

NTC yog lub ntsiab lus ntawm Negative temperature coefficient, uas txhais tau hais tias tsis zoo kub coefficient. Thaum lub ambient kub nce, nws cov nqi kuj txo. Siv cov khoom siv hluav taws xob lossis cov khoom siv them nyiaj los teb rau lub sijhawm thiab tswj kev cuam tshuam sab hauv kom tsis txhob them thiab tso tawm.

ID cim xeeb feem ntau yog ib kab lus sib txuas nco, ID yog lub npe luv ntawm Kev Qhia, uas txhais tau tias kev txheeb xyuas, thiab khaws cov ntaub ntawv xws li roj teeb hom thiab hnub tsim khoom. Nws tuaj yeem siv los txo cov traceability thiab kev siv cov khoom.

PTC yog cov ntawv luv ntawm English Positive Temperature Coefficient, uas txhais tau hais tias qhov kub thiab txias coefficient. Nyob rau hauv txoj hauj lwm, qhov zoo kub coefficient ntaus ntawv feem ntau yog hu ua PTC. Hauv cov khoom siv roj teeb, PTC tuaj yeem tiv thaiv qhov tshwm sim ntawm qhov kub thiab txias thiab tsis muaj kev nyab xeeb siab tam sim no. Raws li qhov voltage, tam sim no ceev tus yam ntxwv thiab daim ntawv thov ib puag ncig ntawm lub roj teeb, muaj tshwj xeeb yuav tsum tau rau PTC.

PTC yog ib qho tseem ceeb heev hauv cov khoom siv roj teeb, thiab nws ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb ntawm cov roj teeb. Nws tus kheej kev ua tau zoo thiab kev ua tau zoo kuj yog ib qho tseem ceeb ntawm kev ua tau zoo thiab cov khoom siv roj teeb zoo.

Thaum lub rooj tiv thaiv kev tiv thaiv ib leeg, kev tsim ntawm lub rooj tiv thaiv kev tiv thaiv yuav yog qhov yooj yim, thiab cov txheej txheem yog tias, piv txwv li, qhov teeb meem ntawm lub platform uas yuav tsum tau them sai sai rau hauv kev tsim ntawm lub hwj chim roj teeb tiv thaiv board, lub roj teeb fais fab feem ntau yuav tsum muaj lub platform loj voltage hauv kev siv. , yog li thaum tsim lub rooj tiv thaiv kev tiv thaiv, sim ua kom lub rooj tsav xwm tiv thaiv tsis cuam tshuam rau qhov hluav taws xob tawm ntawm lub xov tooj ntawm tes, kom cov kev cai rau kev tswj IC, precision resistors thiab lwm yam khoom yuav siab heev. Feem ntau, cov ICs hauv tsev tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov khoom lag luam feem ntau, thiab cov khoom lag luam tuaj yeem siv tau tshwj xeeb. Tam sim no sampling resistors yuav tsum siv JEPSUN resistors kom tau raws li qhov yuav tsum tau ntawm high precision, tsis tshua muaj kub coefficient, thiab tsis muaj inductance. Rau kev tsim ntawm ntau lub xov tooj tiv thaiv lub rooj tsavxwm, muaj cov kev xav tau ntau dua, thiab cov khoom siv nrog cov qib sib txawv ntawm qhov nyuaj yog tsim raws li qhov xav tau sib txawv.
