5. Moyo Wozungulira(unit: nthawi)& Kuzama kwa kutulutsa, DoD
Kuzama kwa kutulutsa: Imawonetsa kuchuluka kwa batire yomwe imatulutsidwa ku kuchuluka kwa batire yomwe idavoteledwa. Mabatire osaya sayenera kutulutsa mphamvu yopitilira 25%, pomwe mabatire akuya atha kutulutsa 80% ya mphamvu zawo. Batire imayamba kutulutsa pamagetsi apamwamba ndipo imasiya kutulutsa pamagetsi otsika. Tanthauzirani zolipiritsa zonse zotulutsidwa ngati 100%. Muyezo wa batri 80% DOD umatanthauza kutulutsa 80% ya mtengowo. Mwachitsanzo, ngati SOC koyambirira ndi 100% ndikuyika pa 20% ndikuyimitsa, ndiye 80% DOD.
Moyo wa batri ya lithiamu-ion udzawola pang'onopang'ono ndi kugwiritsidwa ntchito ndi kusungirako, ndipo zidzakhala zoonekeratu. Tengani mafoni anzeru monga chitsanzo, mutatha kugwiritsa ntchito foni kwa nthawi yayitali, mwachiwonekere mutha kumva batire ya foni "yosalimba", chiyambicho chikhoza kulipira kamodzi patsiku, kumbuyo kungafunikire kulipira kawiri pa tsiku, zomwe. ndiye chisonyezero cha kuchepa kosalekeza kwa moyo wa batri.
Moyo wa batri wa Lithium-ion umagawidwa m'magawo awiri: moyo wozungulira komanso moyo wa kalendala. Moyo wapanjinga nthawi zambiri umayesedwa mozungulira, zomwe zimadziwika ndi kuchuluka kwa nthawi yomwe batire ingachajitsidwe ndikutulutsidwa. Zachidziwikire, pali zinthu pano, nthawi zambiri pa kutentha koyenera ndi chinyezi, ndi mtengo wovotera ndi kutulutsa komweku pakuya kwa mtengo ndi kutulutsa (80% DOD), kuwerengera kuchuluka kwa mizungulira yomwe batire imatsika mpaka 20% za mphamvu zovoteledwa.
Tanthauzo la moyo wa kalendala ndi lovuta kwambiri, batire silingakhale likulipira ndi kutulutsa nthawi zonse, pali zosungirako ndi zosungirako, ndipo sizingakhale nthawi zonse m'malo abwino a chilengedwe, zidzadutsa mumitundu yonse ya kutentha ndi chinyezi. mikhalidwe, komanso kuchuluka kwa kuchulukitsa kwa kulipiritsa ndi kutulutsa kumasinthanso nthawi zonse, kotero moyo weniweni wautumiki uyenera kuyesedwa ndikuyesedwa. Mwachidule, moyo wa kalendala ndi nthawi yoti batire ifike kumapeto kwa moyo (mwachitsanzo, mphamvu imachepa mpaka 20%) pambuyo pa kugwiritsidwa ntchito kwapadera pansi pa malo ogwiritsira ntchito. Moyo wapakalendala umagwirizana kwambiri ndi zofunikira zogwiritsira ntchito, zomwe nthawi zambiri zimafunikira kufotokozedwa kwazomwe zimagwiritsidwa ntchito, momwe chilengedwe, nthawi yosungira, ndi zina zotero.
6. MkatiRkukana(gawo: Ω)
Kukaniza Kwamkati: Zimatanthawuza kukana kwapano komwe kukuyenda kudzera mu batri pamene batire ikugwira ntchito, yomwe imaphatikizapoohmic kukana kwamkatindipolarization mkati kukana, ndi polarization kukana mkati kumaphatikizapoelectrochemical polarization mkati kukanandindende polarization mkati kukana.
Ohmic kukana kwamkatiimakhala ndi ma elekitirodi, electrolyte, kukana kwa diaphragm ndi kukana kukhudzana kwa gawo lililonse.Polarization mkati kukanaamatanthauza kukana komwe kumayambitsidwa ndi polarization panthawi ya electrochemical reaction, kuphatikiza kukana komwe kumachitika chifukwa cha electrochemical polarization ndi polarization yandende.
Chigawo cha kukana kwamkati nthawi zambiri chimakhala milliohm (mΩ). Mabatire okhala ndi kukana kwakukulu kwamkati amakhala ndi mphamvu zambiri zamkati komanso kutentha kwakukulu pakutulutsa ndi kutulutsa, zomwe zingayambitse kukalamba komanso kuwonongeka kwa moyo wa mabatire a lithiamu-ion, komanso kuchepetsa kugwiritsa ntchito kulipiritsa ndi kutulutsa ndi kuchuluka kwakukulu. . Choncho, kukana kwamkati kumakhala kochepa kwambiri, moyo wabwino ndi kuchulukitsa kwa batri ya lithiamu-ion kudzakhala bwino.
