Kodi nthawi yogwira ntchito ya batri ya LiFePO4 ndi yotani komanso nthawi yeniyeni yogwirira ntchito?

Kodi Batri ya LiFePO4 ndi chiyani?
Batire ya LiFePO4 ndi mtundu wa batire ya lithiamu-ion yomwe imagwiritsa ntchito lithiamu iron phosphate (LiFePO4) popanga zinthu zabwino za electrode. Batire iyi imadziwika chifukwa cha chitetezo chake chapamwamba komanso kukhazikika, kukana kutentha kwambiri, komanso magwiridwe antchito abwino kwambiri.

Kodi batire ya LiFePO4 imakhala ndi moyo wautali bwanji?
Mabatire a lead-acid nthawi zambiri amakhala ndi moyo wozungulira wa ma cycle pafupifupi 300, ndipo amakhala ndi ma cycle opitilira 500. Mosiyana ndi zimenezi, mabatire amphamvu a LiFePO4 amakhala ndi moyo wozungulira wopitirira ma cycle 2000. Mabatire a lead-acid nthawi zambiri amakhala ndi moyo wozungulira wa chaka chimodzi mpaka 1.5, omwe amafotokozedwa kuti ndi "atsopano kwa theka la chaka, akale kwa theka la chaka, komanso okonzedwa kwa theka lina la chaka." Pansi pa mikhalidwe yomweyi, paketi ya batire ya LiFePO4 imakhala ndi moyo wokhazikika wa zaka 7 mpaka 8.

Ma batire a LiFePO4 nthawi zambiri amakhala zaka pafupifupi 8; komabe, m'malo otentha, moyo wawo umatha kupitirira zaka 8. Moyo wa batire wa LiFePO4 umaposa nthawi 2,000 zoyatsira magetsi, zomwe zikutanthauza kuti ngakhale atayatsidwa tsiku lililonse, amatha kupitirira zaka zisanu. Pa ntchito zapakhomo, pomwe amayatsidwa magetsi masiku atatu aliwonse, amatha kupitirira zaka zisanu ndi zitatu. Chifukwa cha kutentha kochepa, mabatire a LiFePO4 amakhala ndi moyo wautali m'madera otentha.

Moyo wa batire ya LiFePO4 ukhoza kufika pa ma cycles 5,000, koma ndikofunikira kudziwa kuti batire iliyonse ili ndi chiwerengero cha ma cycles omwe amachajidwa komanso omwe amatuluka (monga ma cycles 1,000). Ngati nambala iyi yapitirira, magwiridwe antchito a batire adzachepa. Kutuluka kwathunthu kumakhudza kwambiri moyo wa batire, kotero ndikofunikira kupewa kutulutsa mphamvu mopitirira muyeso.

Ubwino wa Mabatire a LiFePO4 Poyerekeza ndi Mabatire a Lead-Acid:
Mphamvu Yaikulu: Maselo a LiFePO4 amatha kukhala ndi mphamvu kuyambira 5Ah mpaka 1000Ah (1Ah = 1000mAh), pomwe mabatire a lead-acid nthawi zambiri amakhala ndi mphamvu kuyambira 100Ah mpaka 150Ah pa selo iliyonse ya 2V, ndipo mphamvu zake zimakhala zochepa.

Kulemera Kopepuka: Batire ya LiFePO4 yokhala ndi mphamvu yofanana ndi pafupifupi magawo awiri pa atatu a voliyumu ndi gawo limodzi mwa magawo atatu a kulemera kwa batire ya lead-acid.

Kutha Kuchaja Mofulumira Kwambiri: Mphamvu yoyambira ya paketi ya batire ya LiFePO4 imatha kufika pa 2C, zomwe zimapangitsa kuti itha kuchaja mokwera kwambiri. Mosiyana ndi zimenezi, mabatire a lead-acid nthawi zambiri amafunikira mphamvu pakati pa 0.1C ndi 0.2C, zomwe zimapangitsa kuti kuchaja mwachangu kukhale kovuta.

Kuteteza Zachilengedwe: Mabatire a asidi ya lead ali ndi lead yambiri, yomwe imapanga zinyalala zoopsa. Koma mapaketi a mabatire a LiFePO4 alibe zitsulo zolemera ndipo sayambitsa kuipitsa chilengedwe panthawi yopanga ndi kugwiritsa ntchito.

Zotsika Mtengo: Ngakhale kuti mabatire a lead-acid poyamba amakhala otsika mtengo chifukwa cha mtengo wake, mabatire a LiFePO4 amakhala otsika mtengo kwambiri pakapita nthawi, poganizira nthawi yayitali yogwirira ntchito komanso zosowa zochepa zosamalira. Ntchito zothandiza zikusonyeza kuti mtengo wa mabatire a LiFePO4 ndi wokwera kuwirikiza kanayi kuposa mabatire a lead-acid.
