Kauj Ruam 1: Tom Qab, Ceev Faj & Ceeb Toom

Ua ntej koj pib qhov no, koj yuav tsum paub tias LiPos ib txwm suav tias yog qee yam "tsis hloov pauv" thiab "txaus ntshai." Qhov no yog vim hais tias siv roj teeb LiPo raug paub tias qee zaum tau tua hluav taws, thiab qee qhov tau hlawv tsev lossis tsheb, thiab muaj xov tooj cua ncaj ncees tswj lub dav hlau tau raug hluav taws thaum lub caij sib tsoo, vim LiPos puas. Thaum lub sijhawm tsim nyog lossis tso tawm qeeb, txawm li cas los xij, LiPos yuav tsis tua hluav taws, txawm tias tso tawm txhua txoj hauv kev mus rau 0V/cell. Nws yog theem * rov ua dua * uas yuav ua rau LiPo tso tawm tag nrho kom raug hluav taws, tsis yog theem tso tawm. Qhov laj thawj yog tias thaum LiPo raug coj los qis dua ~ 3.7V/cell, nws qhov kev tiv thaiv sab hauv rau kev them nqi pib nce ntxiv, qee qhov yog tas mus li. Hauv qab ~ 3.0V/cell qhov kev puas tsuaj ua rau muaj txiaj ntsig txaus los saib xyuas. Hauv qab no ~ 2.5V/xov tooj, feem ntau cov tuam txhab tsim khoom LiPo tau hais tias lub roj teeb yog qhov txaus ntshai heev uas yuav tsum tau rov ua dua. Qhov no yog vim tias lub roj teeb sab hauv tiv rau kev them nyiaj tau nce txaus nyob rau lub sijhawm no uas tus txheej txheem them rov qab yuav zoo heev rau LiPo ntawm qhov qis ntawm qib hluav taws xob, txij li tus qauv 1C (1 x lub roj teeb lub peev xwm) them tam sim no tuaj yeem ua rau muaj kev nyab xeeb tsis muaj cua sov tsim nyob hauv roj teeb. Hauv qab ~ 2.0V/cell LiPo tus nqi ntawm kev puas tsuaj sab hauv tau nrawm dua, hauv qab ~ 1.5V/cell qhov kev puas tsuaj (ntxiv, nce ntxiv hauv kev tiv thaiv sab hauv) tau nce ntau ntxiv, thiab nws tsuas yog zuj zus thiab zuj zus. Tus nqi uas qhov kev puas tsuaj no nce ntxiv tsis yog tawm. Tej zaum nws yog lub zog ua haujlwm ntawm, lossis cuam tshuam nrog lub roj teeb qhov hluav taws xob. Hauv ob qho xwm txheej, nws tsis zoo, thiab yuav tsum tau saib xyuas tshwj xeeb. Tam sim no kuv yuav hais tias kuv tau rov ua tiav kaum ob lub roj teeb. Qee qhov phem tshaj uas kuv tau txuas ntxiv siv yog qis li ~ 1.0V/cell. Kuv tau ua tiav kev them rov qab, txawm li cas los xij, roj teeb qis dua li ob peb mV/cell-tej zaum 10mV/cell, lossis 0.010V/cell. Cov roj teeb no tsis muaj txiaj ntsig, txawm li cas los xij, thiab tawm tus kheej rov qab mus rau ~ 0V/cell tom qab tshem lawv tawm ntawm lub charger. Txhais "rov qab": Ua ntej kuv mus ntxiv, cia kuv txhais qhov kuv txhais li cas thaum kuv hais tias kuv tau "rov qab" cov LiPos no. Kuv tsis txhais hais tias kuv tau kho lawv, lossis thim lawv qhov kev puas tsuaj. Kuv tsis txhais hais tias kuv tau coj lawv rov los zoo li tshiab. Qhov tseeb, kuv txhais tau tias kuv tau them rov qab rau lawv kom nyab xeeb, siv tau nyob qhov twg lawv tuaj yeem siv tau txuas ntxiv. Lo lus ceeb toom: Qhov kuv piav qhia hauv qab no yog qhov kuv rov qab tau cov roj teeb li cas. Siv ceev faj. Yog tias koj lub roj teeb nyob ntawm 0.5V/cell, nws qhov kev tiv thaiv sab hauv nyob siab dua yog tias nws tsuas yog poob rau 1.0V/cell, thiab ob qho ntawm cov xwm txheej no muaj kev tiv thaiv sab hauv nyob deb siab dua li LiPo ntawm 1.5V/cell. Ib zaug ntxiv, nws zoo li kuv tias kev sib raug zoo yog * tsis * tawm. Thiab nco ntsoov: kev tiv thaiv sab hauv siab yog dab tsi ua rau muaj cua sov tuaj (thiab muaj peev xwm tua hluav taws yog tias koj tsis ceev faj), thaum rov them dua. Yog li, yog tias koj sim "rov qab" koj LiPos uas tau tso tawm ntau dhau, koj ua lub luag haujlwm tag nrho ntawm qhov yuav tshwm sim tom ntej. Tau hais tias, Kuv tsis tau muaj teeb meem. Tsuas yog lub roj teeb uas txhawj xeeb rau kuv tiag tiag yog ib qho ntawm ~ 0V/cell, yog li kuv tau saib xyuas nws kom zoo zoo, thiab kuv tau them nws * tshwj xeeb tshaj yog * maj mam.

Kauj Ruam 3: Cov Lus Qhia Tseem Ceeb Ua Ntej Koj Pib Them LiPo Tshaj Tawm

CEEB TOOM: thaum pib theem pib kho, thaum LiPos yog <3.0V/cell, tsis txhob tso lawv tseg. Saib xyuas lawv tas li los ntawm kov lawv kom ntseeg tau tias lawv tsis kub, thiab los ntawm qhov pom/kov kom ntseeg tau tias lawv tsis ua puff (puffing yog qhov qhia ntawm cov pa tso tawm los ntawm kev tsim cua sov sab hauv). Ib zaug> 3.0V/cell, koj tuaj yeem tso lawv rau hauv lub thawv ntim hluav taws uas tsis muaj hluav taws thiab txuas ntxiv cov txheej txheem them nqi raws li tau piav qhia hauv cov kauj ruam hauv qab no. Yog tias <3.0V/xov tooj, kuv nyiam tas li hnov lub roj teeb nrog kuv txhais tes los saib xyuas kev tsim hluav taws xob, thiab kuv ib txwm khaws lub LiPo-nyab xeeb them lub hnab nyob ze rau qhov xwm txheej kuv xav pov LiPo hauv lub hnab thiab khiav sab nraum cia LiPo hlawv hauv thaj chaw nyab xeeb (dua, tseem tsis tau tshwm sim, tab sis kuv tsis xav kom qee yam tsis zoo tshwm sim thawj zaug muaj teeb meem).

LiPo-nyab xeeb them lub hnab tuaj yeem yuav hauv ntau qhov chaw, tab sis Amazon ib txwm muaj qhov kev xaiv zoo thiab xa khoom sai heev, yog li saib Amazon qhov kev tshawb fawb tshawb fawb rau "LiPo them lub hnab" ntawm no.

Kauj Ruam 4: Pib Them (LiPo Yog <3.0V/cell)

Thaum <3.0V/cell, them LiPos ntawm qhov txo qis ntawm 1/20 ~ 1/10 C tus nqi (1/20 ~ 1/10 x lawv lub peev xwm) kom txog thaum lawv siab dua 3.0V/cell. Piv txwv: rau LiPo roj teeb qhia nyob rau sab saum toj ntawm cov lus qhia no, 1/20 C tus nqi yuav yog 1/20 x 1.3Ah = 0.065A. Qhov no yog vim lub roj teeb lub peev xwm, raws li tau hais hauv daim ntawv lo, yog 1300mAh (nyeem ua "mili-amp-hours"), lossis 1.3Ah (nyeem ua "amp-hours"). Yog li, 1/20 C tus nqi them yog 1/20 ntawm 1.3, lossis 0.065A. Tus nqi 1/10 C yog 1/10 x 1.3 = 0.13A. Nco tseg tias txawm hais tias qee tus ntse them nyiaj tuaj yeem them tus nqi qis li 0.05A, ntau tus tsis tuaj yeem them tus nqi qis dua 0.1A. Yog tias koj tsis tuaj yeem teeb tsa koj lub roj teeb kom them tus nqi tam sim no tsawg li qhov koj xav tau, tsuas yog xaiv nws qhov teeb tsa qis tshaj plaws, thiab ua tib zoo saib xyuas lub roj teeb thaum lub sijhawm them. siv NiMh lossis NiCad them teeb ntawm LiPo cov roj teeb, vim tias feem ntau cov ntse them nyiaj muaj cov yam ntxwv nyab xeeb uas tiv thaiv tus neeg siv los ntawm kev sim them LiPo uas qis dua 2.5V/cell, vim qhov no tuaj yeem txaus ntshai yog tias tus nqi them tus nqi raug siv. Txij li txhua yam peb tau ua tom qab teeb tsa qis (thiab nyab xeeb) them tam sim no kom tau LiPo rov qab mus rau qib nyab xeeb, siv NiMH/NiCad teeb tsa tau zoo kom txog thaum peb tau txais lub roj teeb> 3.0V/cell. Thaum siv NIMH lossis NiCad teeb tsa kom tau txais LIPOS saum toj no 3.0V/CELL, *** TSIS TXHOB *** QHOV TSEEM CEEB. Koj yuav tsum tsis txhob tso lawv tseg vim tias NiMh/NiCad qhov kawg ntawm kev lees paub txoj hauv kev tsis sib xws nrog Lithium raws cov roj teeb, thiab yog tias sab laug ntawm lub roj teeb kom txog thaum puv, lub xeev kawg-tsis them nyiaj yuav tsis pom thiab LiPo roj teeb yuav raug them ntau dua kom txog thaum nws (zoo li) tua hluav taws thiab rhuav nws tus kheej.

Kauj Ruam 5: Cov Nuj Nqis Tom Ntej

3.0 ~ 3.7V/cell: Ib zaug saum 3.0V/cell, koj tuaj yeem xaiv nce tus nqi mus rau 1/10 ~ 1/5 C tus nqi kom txog thaum LiPos yog ~ 3.7V/cell lossis siab dua. Tej zaum koj yuav tsum tsis txhob tuav lub roj teeb/xav tsis thoob tas li nyob rau lub sijhawm no, thiab tso LiPo rau hauv lub thawv ntim hluav taws lossis LiPo-nyab xeeb them lub hnab ntawm lub sijhawm no, yog tias xav tau. 3.7 ~ 4.2V/cell: Ib zaug saum toj no kwv yees 3.7V/cell, koj tuaj yeem xaiv nce tus nqi them ntxiv rau 1/2 C tus nqi kom txog thaum lawv puv (4.20V/cell).

Kauj Ruam 6: Rov Qab Los Siv Li Cas

Tam sim no, siv cov roj teeb zoo li qub. Lub roj teeb qis dua tau tso tawm, ntau qhov kev puas tsuaj tas li nws yuav muaj. Yog tias koj siv lub roj teeb (piv txwv li: ya lub dav hlau RC), thiab nws ua haujlwm tau zoo, tom qab ntawd koj tuaj yeem ntseeg tau tias kev them nqi tom ntej ntawm 1C yog qhov tau txais dua. Saib nws nyob rau ob peb hlis tom ntej, txawm li cas los xij, thiab xyuas kom lub roj teeb tsis puff thaum tso tawm lossis them nyiaj. Qhov no yuav yog qhov qhia tias kev tiv thaiv sab hauv ntawm lub roj teeb tseem siab dhau rau kev siv ib txwm muaj thiab tus qauv 1C tus nqi them. Hauv txhua qhov xwm txheej, vim tau tso lub LiPos ntau dhau, koj yuav pom qhov txo qis hauv lawv lub peev xwm (mAh) lossis qhov tso tawm ntau tshaj plaws (piv txwv li: lawv yuav zoo li muaj qhov tso tawm qis C-ntsuas, raws li tau sau tseg los ntawm qis zog tso tawm; txo kev ua haujlwm), raws li lub roj teeb sab hauv kev tiv thaiv yuav tau nce ntxiv, thiab qee qhov kev puas tsuaj tas mus li yuav muaj. Ib qho ntxiv, kev ua neej nyob ntev ntawm LiPo tso tawm ntau dhau (piv txwv li: muaj pes tsawg lub voj voog koj tuaj yeem tawm ntawm nws) yuav raug txo qis. Qhia rau kuv paub tias qhov no ua haujlwm zoo rau koj! Nyob nyab xeeb!
