Kev Taw Qhia:
Hauv cov lus yooj yim, kev sib npaug yog qhov nruab nrab ntawm qhov sib npaug voltage. Khaws qhov voltage ntawmroj teeb lithiumsib xws. Kev sib npaug yog muab faib ua kev sib npaug nquag thiab kev sib npaug tsis siv neeg. Yog li qhov txawv ntawm kev sib npaug nquag thiab kev sib npaug tsis siv neeg ntawm lub rooj tsavxwm tiv thaiv roj teeb lithium yog dab tsi? Cia peb saib nrog Heltec Energy.
Kev sib npaug ntawm lub lithium roj teeb tiv thaiv board
Kev sib npaug zog yog tias cov hlua uas muaj hluav taws xob siab ntxiv zog rau cov hlua uas muaj hluav taws xob qis, yog li lub zog tsis raug pov tseg, hluav taws xob siab tuaj yeem txo qis, thiab hluav taws xob qis tuaj yeem ntxiv. Hom kev sib npaug zog no tuaj yeem xaiv qhov loj ntawm hluav taws xob sib npaug ntawm koj tus kheej. Feem ntau, 2A feem ntau siv, thiab kuj tseem muaj cov loj nrog 10A lossis siab dua.
Tam sim no cov khoom siv sib npaug nquag hauv khw feem ntau siv lub hauv paus ntsiab lus transformer, vam khom cov chips kim ntawm cov chaw tsim khoom chip. Ntxiv rau qhov sib npaug chip, kuj tseem muaj cov khoom siv kim xws li transformers, uas loj thiab kim heev.
Qhov cuam tshuam ntawm kev sib npaug nquag yog qhov pom tseeb heev: kev ua haujlwm zoo, lub zog tsawg dua hloov pauv thiab tsis yaj hauv daim ntawv ntawm cua sov, thiab qhov poob tsuas yog lub kauj ntawm lub transformer.
Qhov kev sib npaug tam sim no tuaj yeem xaiv tau thiab qhov ceev ntawm kev sib npaug yog ceev. Kev sib npaug nquag yog qhov nyuaj dua hauv cov qauv dua li kev sib npaug passive, tshwj xeeb tshaj yog txoj kev transformer. Tus nqi ntawm BMS nrog kev ua haujlwm sib npaug nquag yuav siab dua li ntawm kev sib npaug passive, uas kuj txwv qee qhov kev txhawb nqa ntawm kev sib npaug nquagBMS.
Kev sib npaug ntawm lub lithium roj teeb tiv thaiv board
Kev sib npaug passive feem ntau yog ua los ntawm kev ntxiv cov resistors rau hauv qhov tso tawm. Cov hlua hluav taws xob siab ntawm cov cell raug tso tawm hauv daim ntawv ntawm kev tso cua sov mus rau thaj chaw ib puag ncig, ua tiav cov txiaj ntsig ntawm kev txias lub resistor. Qhov tsis zoo yog tias qhov tso tawm yog raws li cov hlua hluav taws xob qis tshaj plaws, thiab muaj qhov ua tau ntawm kev pheej hmoo thaum them.
Kev sib npaug tsis siv neeg feem ntau yog siv vim nws tus nqi qis thiab txoj cai ua haujlwm yooj yim; nws qhov tsis zoo yog tias nws sib npaug raws li lub zog qis tshaj plaws, thiab tsis tuaj yeem ntxiv cov hlua hluav taws xob qis, ua rau muaj kev pov tseg zog.
Qhov sib txawv ntawm kev sib npaug nquag thiab kev sib npaug passive
Kev sib npaug tsis siv neeg yog qhov tsim nyog rau cov peev xwm me me, qis voltageroj teeb lithium, thaum lub zog sib npaug zoo yog qhov tsim nyog rau cov roj teeb lithium uas muaj zog heev, muaj peev xwm loj.
Cov thev naus laus zis them nqi sib npaug uas siv ntau suav nrog kev them nqi tas mus li ntawm cov resistor sib npaug, kev them nqi on-off shunt resistor sib npaug, kev them nqi nruab nrab ntawm cov roj teeb hluav taws xob sib npaug, kev them nqi hloov pauv capacitor sib npaug, kev them nqi buck converter sib npaug, kev them nqi inductor sib npaug, thiab lwm yam. Thaum them ib pawg roj teeb lithium hauv series, txhua lub roj teeb yuav tsum tau them sib npaug, txwv tsis pub qhov ua tau zoo thiab lub neej ntawm tag nrho pawg roj teeb yuav raug cuam tshuam thaum siv.
| Cov yam ntxwv | Kev sib npaug tsis tu ncua | Kev sib npaug nquag |
| Txoj cai ua haujlwm | Siv zog ntau dhau los ntawm cov resistors | Sib npaug lub zog roj teeb los ntawm kev hloov pauv zog |
| Kev poob zog loj | lub zog pov tseg ua cua sov Me me | kev hloov pauv hluav taws xob zoo |
| Tus nqi | Qis | Siab |
| Kev nyuaj siab | Kev siv tshuab qis, laus zuj zus | Yuav tsum tau tsim qauv hluav taws xob siab thiab nyuaj |
| Kev Ua Haujlwm Zoo | Tsawg, cua sov poob | Siab, yuav luag tsis muaj kev poob zog |
| Siv tau | cov xwm txheej Cov pob roj teeb me me lossis cov ntawv thov pheej yig | Cov roj teeb loj lossis cov ntawv thov ua haujlwm siab |
Lub hauv paus ntsiab lus ntawm kev sib npaug passive yog kom ua tiav qhov txiaj ntsig sib npaug los ntawm kev pov tseg lub zog ntau dhau. Feem ntau, lub zog ntau dhau hauv lub roj teeb overvoltage hloov pauv mus ua cua sov los ntawm lub resistor, yog li ntawd lub roj teeb voltage tseem sib xws. Qhov zoo yog tias lub voj voog sib npaug passive yog yooj yim thiab tus nqi tsim thiab kev siv yog qis. Thiab cov thev naus laus zis sib npaug passive yog mature heev thiab tau siv dav hauv ntau tus nqi qis thiab me me.cov pob roj teeb.
Qhov tsis zoo yog tias muaj kev poob zog loj vim yog kev hloov pauv ntawm lub zog hluav taws xob mus rau hauv cua sov los ntawm kev tiv thaiv. Kev ua haujlwm qis, tshwj xeeb tshaj yog nyob rau hauv cov roj teeb loj, kev pov tseg zog pom tseeb dua, thiab nws tsis haum rau kev siv roj teeb loj, kev ua haujlwm siab. Thiab vim tias lub zog hluav taws xob raug hloov pauv mus rau hauv cua sov, nws yuav ua rau lub roj teeb kub dhau, cuam tshuam rau kev nyab xeeb thiab lub neej ntawm tag nrho lub cev.
Kev sib npaug nquag ua tiav kev sib npaug los ntawm kev hloov lub zog hluav taws xob ntau dhau los ntawm cov roj teeb uas muaj hluav taws xob ntau dua mus rau cov roj teeb uas muaj hluav taws xob tsawg dua. Txoj kev no feem ntau kho qhov kev faib hluav taws xob ntawm cov roj teeb los ntawm kev hloov pauv hluav taws xob, cov khoom siv hloov pauv buck-boost lossis lwm yam khoom siv hluav taws xob. Qhov zoo yog kev ua haujlwm zoo: lub zog tsis raug pov tseg, tab sis sib npaug los ntawm kev hloov pauv, yog li tsis muaj cua sov poob, thiab kev ua haujlwm zoo feem ntau siab (txog li 95% lossis ntau dua).
Kev txuag hluav taws xob: Vim tias tsis muaj kev pov tseg hluav taws xob, nws tsim nyog rau lub peev xwm loj, kev ua haujlwm siabroj teeb lithiumcov kab ke thiab tuaj yeem ua kom lub roj teeb siv tau ntev dua. Siv tau rau cov roj teeb loj: Kev sib npaug zoo yog qhov tsim nyog dua rau cov roj teeb loj, tshwj xeeb tshaj yog hauv cov xwm txheej xws li tsheb fais fab thiab cov tshuab khaws cia hluav taws xob, thiab tuaj yeem txhim kho kev ua haujlwm zoo thiab kev ua haujlwm ntev.
Qhov tsis zoo yog tias kev tsim thiab kev siv ntawm kev sib npaug nquag yog qhov nyuaj heev, feem ntau xav tau ntau yam khoom siv hluav taws xob, yog li tus nqi siab dua. Kev nyuaj ntawm kev siv tshuab: Yuav tsum muaj kev tswj hwm qhov tseeb thiab kev tsim qauv hluav taws xob, uas nyuaj thiab yuav ua rau muaj kev nyuaj ntawm kev txhim kho thiab kev saib xyuas.
