UPS Battery Internal Resistance: Kodi Muyenera Kusintha Liti? | | DFUN

Chidziwitso Chachangu: Zosintha Zamkati Zam'kati

Zimakwera Pamwamba Pa	Momwe Mungagwiritsire Ntchito	Zoyenera Kuchita
Pansi pa 30%	Wamba	Pitirizani kuyendera nthawi zonse
30% - 50%	Penyani	Wonjezerani pafupipafupi kuyendera, kutsatira zomwe zikuchitika
Kupitilira 50%	Bwezerani Posachedwapa	Onjezani ku pulani yolowa m'malo, ikani patsogolo pa bajeti
Kupitilira 100% (2x zoyambira)	Selo Yolephera	Bwezerani mwachangu, samalirani ngati gawo lotsalira

Izi zimagwira ntchito motsutsana ndi zomwe zidajambulidwa ndi selo - osati kuchuluka kwamakampani. Kukaniza mkati mwafakitale kumasiyanasiyana malinga ndi mphamvu, chemistry, ndi mtundu, kotero malo odalirika kwambiri ndi kuwerenga komwe kumayikidwa komwe batire inali yatsopano.

Zomwe Zimakhazikitsa Kukaniza Kwamkati, Osati Nambala Yokhazikika

Kukana kwa batri la VRLA kumaphatikizapo zigawo ziwiri: ohmic resistance (mbale, electrolyte, straps straps) ndi polarization resistance (charge-transfer and ion-diffusion resistance from electrochemical reaction). Nambala yomwe woyesa wam'manja alipoti ndi kuchuluka kwa onse awiri.

Mabatire atsopano ochokera mgulu lofananira lopangidwa mokhazikika mozungulira mtengo wokhazikika. M'zaka za batri - kuwonongeka kwa mbale, kutayika kwa zinthu zogwira ntchito, kuuma kwa electrolyte, sulfation - mtengowo umakwera pang'onopang'ono. Kukaniza kwamkati ndikoyimira kolimba kwa thanzi, koma powerenga motsutsana ndi chiyambi chodziwika.

Factory Internal Resistance by Capacity

Factory mkati kukana correlates mwachindunji ndi mphamvu - mbale zazikulu, kukana kutsika. Mawonekedwe wamba a 12V UPS amasiyana kwambiri ndi njira yaukadaulo:

Mtundu wa Battery Mtundu	Wofananira	wa Factory Internal Resistance (Reference)
Standard AGM VRLA	12V 100Ah	~ 4–6 mΩ
Gel yogwira ntchito kwambiri ya moyo wautali	12V 100Ah	~2–3 mΩ kapena kutsika

Awa ndi milingo yolozera okha. Kusiyanasiyana kwamtundu wamtundu ndi malonda ndikofunikira - nthawi zonse muzitsimikizira motsutsana ndi zolemba za wopanga, ndikujambulitsa muyeso woyikidwa wa batire yatsopano iliyonse ngati maziko enieni a chingwecho.

Lamulo la 50%-Pamwambapa-Baseline

Chiyerekezo chamakampani chomwe chimagwiritsidwa ntchito kwambiri: kukana kwamkati kwa selo kukapitilira 50% yojambulidwa, thanzi lake latsika momveka bwino kotero kuti liyenera kutsatiridwa ndikukonzekera kusintha.

Chitsanzo: batire ya 100Ah yokhala ndi 5 mΩ yoyambira yowerengera 7.5 mΩ patatha zaka zitatu idadutsa mzere wa 50%. Ngati ipitilira kukwera kupitirira kuwirikiza koyambira (10 mΩ), itengeni ngati selo yotsimikizika yolephera.

Chifukwa Chake Kupatuka kwa Maselo ndi Maselo Kuli Kofunika Kwambiri Monga Nambala Yonse

Kupitilira mtengo wamtheradi wa cell imodzi, kusasinthika pamndandanda ndikofunikira. Selo yowerengera 20-30% yokwera kuposa oyandikana nayo imawonetsa kusalinganika kwakukulu kwa paketi, ngakhale isanadutse mzere wa 50% -pamwambapa wokha.

The Wofooka Cell Effect

Chingwe cha batri ndi chodalirika ngati selo lake lofooka kwambiri. Selo imodzi yokana kwambiri:

• Imakoka magawo osagwirizana ndi ma voliyumu ochapira, kuthamanga kwambiri komanso kuchulukira
• Imakomoka koyamba ikatulutsa, zomwe zimagwira ntchito ya chingwe chonsecho
• Imafulumizitsa ukalamba m'maselo oyandikana nawo kudzera mu mphamvu yamafuta ndi magetsi

BMS yophatikizika ya DFUN imazindikiritsa maselo ofooka koyambirira kudzera pakutsata mosalekeza; kuyesa mphamvu kumatsimikizira ngati m'malo kufunikira - kuchokera papulatifomu yomweyo.

Kudumpha Mwadzidzidzi Ndi Chizindikiro Champhamvu Chochenjeza Kuposa Kuwerenga Kwambiri

Kukana kwamkati kumakwera pang'onopang'ono komanso pang'onopang'ono chaka ndi chaka. Kudumpha mwadzidzidzi pakati pa kuyang'ana kawiri motsatizana - osati chiwerengero chachikulu chokha - ndicho chizindikiro champhamvu kwambiri cha kuwonongeka kwakukulu: kutsika kwapang'onopang'ono, kuphulika kwa mbale, kutaya madzi kwakukulu, kapena sulfation yapamwamba. Kuwunika kosalekeza kumagwira kusinthaku nthawi yomweyo; kuyesa kwapachaka kokhazikika kumatha kuphonya kwa miyezi ingapo.

Musadalire Kukaniza Kwamkati Kokha

• Kukana kwanthawi zonse sikutsimikizira kuchuluka kwabwino. Maselo ena amayesa kukana pomwe mphamvu yogwiritsiridwa ntchito yatsika kale.
• Mphamvu yoyandama yanthawi zonse imatsimikizira kukana kwanthawi zonse. Voltage yoyandama nthawi zambiri imayikidwa ndi charger, osati mphamvu yosungidwa ya cell - cell yolimba kwambiri imatha kuwerengabe mphamvu yabwinobwino.
• Kuyesa kutulutsa mphamvu ndiye chowonadi chenicheni. Kutulutsa kosalekeza kwa 0.1C kumagetsi a cutoff kumakhalabe njira yodalirika yotsimikizira mphamvu zenizeni; Zotsatira zochepera pa 80% za kuchuluka komwe adavotera nthawi zambiri zimawonetsa kutha kwa moyo.
• Kuyang'ana kowoneka kumaposa deta. Kuphulika kwamilandu, valavu yoteteza chitetezo, kapena malo owonongeka kwambiri amatanthauza kusintha nthawi yomweyo, mosasamala kanthu za kukana kuwerenga.

M'malo mwa Njira Yogwiritsira Ntchito Tier

Application Tier	Yomwe Yalimbikitsidwa
Mission-critical (data center core, chipatala OR, malonda azandalama)	Lembani pa 30% pamwamba pa zoyambira; kupita ku mapulani olowa m'malo pa 50%. Osadikirira kuyesa kolephera.
General Enterprise / telecom base station	Lembani pa 50% pamwamba pa zoyambira; sinthani pa 100%+ (2x zoyambira). Yang'anani ma cell otsala pang'ono kwambiri poyamba ngati ali ndi bajeti.
Moyo wopangidwa kale wa chingwe	Yambani kukonza bajeti mosasamala kanthu za kukana kuwerengera - moyo wa kalendala ndi moyo wozungulira ndi zinthu zodziyimira pawokha.

Ntchito Zamakampani

Ma Data Center

Pewani kulephera kwa batri la UPS, sungani nthawi ya 24/7, ndikukonzekera zolosera m'malo mosinthana mwadzidzidzi.

Telecom Networks

Yang'anirani masiteshoni akutali mosalekeza, chepetsani magalimoto oyenda, ndikugwira ma cell oyipa asanazime.

Zida Zamagetsi & Magawo

Onetsetsani kudalirika kwa dongosolo la DC ndikuthandizira malipoti otsatiridwa ndi data yopitilira pa selo iliyonse.

Zipatala

Tetezani zida zachipatala zofunika kwambiri ndikuchepetsa chiopsezo cha kuwonongeka kwa batri mosadziwikiratu musanayambe kuzimitsa.

Mafunso Ofunsidwa Kawirikawiri (FAQ)

Kodi pali mtengo wotsutsa wamkati womwe batire ya UPS iyenera kusinthidwa?

Palibe nambala imodzi yomwe imagwira ntchito pamitundu yonse ndi luso. Njira yodalirika ndikufanizira kuwerengera kwa selo lililonse ndi gawo loyambira lomwe lakhazikitsidwa, osati kuchuluka kwamakampani.

Kodi batire ingalepherebe kuyesa mphamvu ngakhale kukana kwamkati kumawoneka ngati kwabwinobwino?

Inde. Maselo ena amasunga kuwerengera kovomerezeka pomwe mphamvu yatsikira kale pansi pazipata zomwe zingagwiritsidwe ntchito, ndichifukwa chake kuyezetsa kutulutsa kwapang'onopang'ono kumakhalabe kofunikira limodzi ndi kuwunika kwa kukana.

Chifukwa chiyani magetsi oyandama angawoneke ngati abwinobwino pa batri yomwe ikufunika kusinthidwa?

Mphamvu yamagetsi yoyandama imasungidwa kwambiri ndi kutulutsa kwa charger m'malo mwa mphamvu ya batri yomwe yasungidwa, kotero kuti selo lolimba kwambiri limatha kuwonetsa kuwerengera kwamagetsi wamba.

Kodi kukana kwamkati kumayesedwa kangati?

Kotala ndizofala kwa malo ofunikira kwambiri; semi-pachaka kwa mabizinesi wamba kapena ma telecom. Kuwunika mosalekeza kwa BMS kumafupikitsa izi kukhala nthawi yeniyeni potsata zomwe zikuchitika.

Kodi dongosolo la DFUN likhoza kuyika selo lomwe likutsalira lisanayambitse?

Inde. Kusasunthika kosalekeza kwa mkati mwa selo imodzi ndi kusinthasintha kwa kutentha kumatha kuwonetsa ma cell omwe akuchedwa masabata kapena miyezi ingapo kuti agwire ntchito yoyendera.
