Yog li no, niaj hnub no peb yuav sim xyuas seb qhov sib txawv ntawm cov kev daws teeb meem lithium rau UPS thiab cov roj teeb hauv koj lub cuab yeej li cas, yuav ua li cas cov kev ua haujlwm ntawm cov roj teeb hauv chav neeg rau zaub mov txawv, vim li cas hauv lub xov tooj Li-Ion lub roj teeb kav ntev li cas. ntau tshaj 2-3 xyoos, thiab nyob rau hauv ib lub chaw cov ntaub ntawv no daim duab yuav nce mus rau 10 los yog ntau tshaj xyoo. Vim li cas qhov kev pheej hmoo ntawm lithium hluav taws kub hauv cov ntaub ntawv chaw / chav tsev neeg rau zaub mov tsawg tsawg.

Yog lawm, kev huam yuaj nrog UPS roj teeb tuaj yeem ua tau txawm tias hom khoom siv hluav taws xob, tab sis cov lus dab neeg ntawm "kev phom sij hluav taws" ntawm cov kev daws teeb meem lithium tsis muaj tseeb.

Tom qab tag nrho, ntau tus tau pom qhov ntawd video ntawm xov tooj ntes hluav taws nrog lub roj teeb lithium hauv lub tsheb txav ntawm txoj kev loj? Yog li, cia peb saib, xam nws tawm, piv ...

Ntawm no peb pom ib qho xwm txheej ntawm kev tswj tsis tau tus kheej cua sov, thermal runaway ntawm lub xov tooj roj teeb, uas ua rau muaj qhov xwm txheej zoo li no. Koj yuav hais tias: NO! Nws tsuas yog lub xov tooj xwb, tsuas yog tus neeg vwm yuav muab qee yam zoo li ntawd rau hauv chav server!

Kuv paub tseeb tias tom qab kawm cov ntaub ntawv no, tus nyeem ntawv yuav hloov nws txoj kev xav txog qhov teeb meem no.

Cov xwm txheej tam sim no hauv kev lag luam data center


Nws tsis pub leejtwg paub tias kev tsim lub chaw khaws ntaub ntawv yog kev nqis peev mus ntev. Tus nqi ntawm cov khoom siv engineering ib leeg tuaj yeem yog 50% ntawm tus nqi ntawm tag nrho cov nqi peev. Lub sijhawm them rov qab yog kwv yees li 10-15 xyoo. Lawm, muaj lub siab xav txo tus nqi tag nrho ntawm cov tswv cuab thoob plaws hauv lub neej tag nrho ntawm cov ntaub ntawv chaw, thiab tib lub sij hawm kuj compact engineering cov cuab yeej, tso tawm ntau qhov chaw ntau li ntau tau rau lub payload.

Qhov kev daws teeb meem zoo tshaj plaws yog kev rov ua dua tshiab ntawm kev lag luam UPS raws li Li-Ion roj teeb, uas tau tshem tawm "cov kab mob me me" ntev ntev los ntawm kev phom sij hluav taws, tsis raug them nqi hluav taws xob algorithms, thiab tau txais ntau cov txheej txheem tiv thaiv.

Nrog rau kev nce hauv lub peev xwm ntawm kev suav thiab cov khoom siv network, qhov kev thov rau UPS tau loj hlob.

Raws li cov saum toj no, rau rooj plaub ntawm kev siv lithium kev daws teeb meem hauv UPS, cov kev pheej hmoo hauv qab no tseem cuam tshuam:

  1. Thermal runaway ntawm lub xov tooj ntawm tes los yog module raws li ib tug tshwm sim ntawm ib tug sab nraud luv luv Circuit Court - ob peb theem ntawm kev tiv thaiv.
  2. Thermal runaway ntawm ib lub xov tooj ntawm tes los yog module raws li ib tug tshwm sim ntawm lub internal roj teeb malfunction - ob peb theem ntawm kev tiv thaiv ntawm lub cell los yog module theem.
  3. Overcharge - kev tiv thaiv los ntawm BMS ntxiv rau txhua qib kev tiv thaiv rau khib, module, cell.
  4. Kev puas tsuaj rau tshuab tsis cuam tshuam rau peb cov ntaub ntawv, qhov kev pheej hmoo ntawm qhov kev tshwm sim yog negligible.
  5. Overheating ntawm khib thiab tag nrho cov roj teeb (modules, cell). Uncritical mus txog 70-90 degrees. Yog tias qhov kub thiab txias hauv chav tsev teeb tsa UPS nce siab dua cov txiaj ntsig no, nws txhais tau tias muaj hluav taws kub hauv lub tsev. Raws li cov ntaub ntawv chaw ua haujlwm ib txwm muaj, qhov kev pheej hmoo ntawm qhov xwm txheej yog qhov tsis txaus ntseeg.
  6. Txo roj teeb lub neej ntawm chav tsev kub siab - kev ua haujlwm mus sij hawm ntev ntawm qhov kub txog li 40 degrees yog tso cai yam tsis muaj qhov txo qis hauv roj teeb lub neej. Cov roj teeb txhuas muaj kev nkag siab zoo rau txhua qhov kev nce hauv qhov kub thiab txias thiab txo lawv lub neej nyob rau hauv kev faib ua feem rau qhov kub thiab txias.
