Kev txiav txim siab zoo yuav tsum daws kom meej qhov kev xav tau ntawm qhov chav siv thiab lub battery kom tau qhov tsim nyog thiab nyob ntev.

Paub Txog 18650 Battery Specifications

Qhov Kub Thiab Qhov Chaw Kuaj

Qhov hluaj li cas ntawm lub 18650, xws li mAh, yuav txiav txim seb thaum twg koj tus tais kheej yuav tig tau ib zaug. Lub tais kheej feem ntau tuaj yeem muaj qhov hluaj li 2000mAh mus rau 3500mAh, lub tais kheej uas hluaj dua feem ntau yuav tso caij ntev dua tab sis tsis yog tias yuav tso siab tsawg dua. Yog koj paub txog qhov siv hluaj ntawm koj tus tais kheej, ces koj tuaj yeem txiav txim seb koj xav tau qhov hluaj siab tshaj plaws lossis qhov tshwm sim uas nyob rau sab xis.

Qhov hluaj hauv chav tuab ceev hlo sib txawv nyob rau hauv qhov kev sib npaug thiab qhov chav tuab. Lub tais kheej uas hluaj dua feem ntau siv cov khoom siv tshwj xeej uas pab ruaj khov qhov hluaj hauv chav tuab 18650. Tab sis, cov kev pab hlo siv no tsis yog tias muaj kev txwv rau qhov tso hluaj, lub sijhawm tso, lossis qhov tsim nyog rau koj qhov kev siv tshwj xeej.

Pep Hluaj Thiab Qhov Tso Hluaj

Tus li ti siv ntau tshaj plaws 18650 tuaj noj yuav muaj voltage tshwj xeeb ntawm 3.6V txog 3.7V, thiab voltage kawg siv tau txog 4.2V, thaum li tshem tsis pub tshem ntau dua 2.5V txog 3.0V. Daim duab ntawm kev tshem yog qhov tseem ceeb rau koj tus tshuab nyob hauv qhov chaw twg thaum li tshem, vim muaj qhov kev siv xwm txheej xwm txheej kom tsim nyog nyob rau hauv qhov chaw siv tag nrho.

Kev paub txog qhov voltage xav tau yog qhov tseem ceeb thaum koj xa li thiab xa tus li rau tus tshuab uas muaj qhov voltage tshwj xeeb. Muaj qhov tshuab tuaj yeem ua haujlwm zoo nyob rau hauv qhov voltage ncig, yog li qhov kev xaiv tus li yog qhov tseem ceeb rau kev tswj haujlwm zoo thiab kho kom tsis txhob muaj kev tshem voltage tsuas mus rau thaum rov qab los, uas tuaj yeem tshem tawm kev ua haujlwm lossis kev sau ntaub ntawv.

Txoj Haujlwm Zoo Thiab Kev Siv Suv Rau Qhov Xyaum

Kev Txheej Li thiab Kev Pab Ntau Zog

Qhov siv zog tagjurr tagjrur ntawm ib 18650 battery txhais nws qhov kev pab tau rau lub sib ntxiv rau cov cuab yeej uas tso caij ntau. Cov cell siv hluas feem ntau muab 5A txog 10A thiab tso caij ntev, thaum cov cell tso caij ntau tuaj yeem muab 20A lossis ntau dua. Sib phim qhov kawg ntawm lub current rau koj cov cuab yeej yuav tsum tau kom tsis txhob muaj qhov voltage sag, tshav rooj loj, thiab lub sijhawm twg lub battery pom tsha nyob tam sim thiaj li tsha tseg thaum cov cell ua haujlwm ntau dua qhov kho los.

Cov kev pab tau ntawm peak current feem ntau loj dua qhov continuous ratings rau sijhawm luv, pab rau cov cuab yeej kom ua haujlwm nrog qhov tso caij ntau nyob ib sijhawm lossis qhov tso caij ntau ib sijhawm. Tab sis, yog tshem tsi rau qhov peak rating rau kev siv ntev yuav tshwm sim tshav rooj loj thiab sijhawm siv pom tsha. Cov kev siv hauv kev lag luam feem ntau xav tau cov cell kho los rau qhov siv ntau, muaj kev saib xyuas tshav rooj zoo dua thiab muaj qhov chaw nruj meej dua.

Cycle Life thiab Durability Considerations

Daim ntawv tsim hauv cheeb tsam yog qhov muaj ntau zaus uas li ti battery tuaj yeem pib thiab tig tawm, thaum twg nws nyob ib feem ntawm qhov tshwm sim tas li, feem ntau yog 80% ntawm qhov tshwm sim dhau los. Cov cell 18650 zoo tuaj yeem tau 500 mus rau 1000+ zaus nyob rau hauv kev siv zoo, tab sis txoj cai siv tseem nyob ntawm qhov tshwm sim, kev siv, thiab cov cuab yeej kuaj mob.

Kev tiv thaiv teb nthuab muaj feem ntau rau kev siv hauv siav thiab kev nyob siav dua. Ntau hnub ntu cell siv los ntawm 0°C mus rau 45°C, thaum cov chav siv siv rau kev lag luam tuaj yeem nce ntau dua. Teb nthuab loj yees tsha tshuaj xyuas qhov tshwm sim thiab tuaj yeem tsim kev phem nyug, ua rau kev tiv thaiv yog qhov tseem ceeb nyob rau hauv kev xaiv thiab kev tsim kho battery.
