Qhov kawg-ntawm-tso tawm voltage ntawm lithium roj teeb yog ib qho tseem ceeb daim ntawv thov tsis muaj feem xyuam rau lub neej kev pab cuam ntawm lithium roj teeb. Tam sim no, lub nominal voltage ntawm ib lub roj teeb lithium feem ntau yog tsim los ua 3.7V, thiab qhov txiav tawm voltage yog 2.75V. Muaj ob qhov xwm txheej uas ua rau cov chaw tsim khoom nce siab tshaj ntawm qhov kev txiav tawm hluav taws xob mus rau 3.0V. Ib qho yog cov khoom siv hluav taws xob tau txiav txim siab los ntawm cov khoom siv roj teeb lithium, uas feem ntau yog Los ntawm qhov kev xav ntawm kev siv roj teeb zoo dua; qhov thib ob yog txuas nrog cov khoom siv hluav taws xob tshwj xeeb thiab cov khoom siv hluav taws xob. Tau kawg, kuj tseem muaj qhov sib txawv, qhov kev txiav tawm hluav taws xob tuaj yeem tsim kom qis dua, xws li 2.5V thiab 2.4V, tab sis tsis muaj qis dua 2.4V.

Yog hais tias qhov kev khiav hauj lwm kub thaum lub sij hawm tso tawm nyob rau hauv qhov ntau ntawm -20 ~ 60 degree, lub lithium roj teeb nrog ib tug txiav tawm voltage ntawm 2.75V tuaj yeem txuas mus ntxiv, tab sis nws yuav tsum tsis txhob qis dua 2.5V. Raws li tau hais ua ntej, nruab nrab ntawm 2.75V thiab 2.5V Lub sijhawm poob yuav yog ib feem, thiab qis dua 2.5V yuav ua rau muaj kev puas tsuaj loj tshaj plaws, ua rau lub roj teeb siv tsis tau.

Lithium roj teeb pob kuj muaj qhov txiav tawm voltage. Hom roj teeb lithium no qee zaum hu ua "cell lithium roj teeb". Qhov tso tawm qhov hluav taws xob ntawm "cell lithium roj teeb" yuav tsum tsis txhob tsawg dua 2.75 × n (n yog cov roj teeb hauv cov koob), thiab cov khoos phis tawj phau ntawv yog feem ntau siv. Coj tus 6- roj teeb lithium ntawm tes ua piv txwv. Qhov no 6- roj teeb lithium ntawm tes feem ntau txais kev sib txuas ntawm 3 series thiab 2 parallels. Yog li ntawd, qhov tso tawm hluav taws xob ntawm lub roj teeb lithium no yog 2.75V × 3=8.25V, thiab qhov tsawg kawg nkaus tus nqi tsis tuaj yeem qis dua 2.5V. × 3=7.5V.

Qhov tseeb, vim tias cov roj teeb lithium kuj tseem kim, ob qho tib si lithium roj teeb thiab ntau lub roj teeb lithium tau nruab nrog cov pawg tiv thaiv lossis tiv thaiv ICs. teeb liab, tus neeg siv yuav tsum nco ntsoov txoj kev ua haujlwm.
