M'dziko lomwe likukula mwachangu la mabatire, Lithium Iron Phosphate (LFP) yapeza chidwi kwambiri chifukwa chachitetezo chake chabwino komanso moyo wautali wozungulira. Komabe, kuyang'anira magwero a magetsi amenewa mosatekeseka kumakhalabe kofunika kwambiri. Pamtima pachitetezochi pali Battery Management System, kapena BMS. Njira zodzitchinjiriza zotsogolazi zimagwira ntchito yofunika kwambiri, makamaka popewa zinthu ziwiri zomwe zingawononge komanso zowopsa: chitetezo chachargecharge, komanso chitetezo chotulutsa kwambiri. Kumvetsetsa njira zotetezera mabatire izi ndizofunikira kwa aliyense amene amadalira ukadaulo wa LFP posungira mphamvu, kaya ndi makhazikitsidwe apanyumba kapena mabatire akuluakulu amakampani.
Chifukwa Chake Chitetezo Chowonjezera Ndi Chofunikira Pamabatire a LFP
Kuchulukirachulukira kumachitika pamene batire ikupitilizabe kulandila mphamvu kupitilira momwe idazingidwira. Kwa mabatire a LFP, izi sizongowonjezera vuto chabe-ndi ngozi yachitetezo. Kuchuluka kwamagetsi panthawi yacharge kungayambitse:
- Kutentha kofulumira: Izi zimafulumizitsa kuwonongeka ndipo, zikavuta kwambiri, zimatha kuyambitsa kuthawa kwa kutentha.
- Kuchuluka kwamphamvu kwamkati: Kupangitsa kuti ma electrolyte atayike kapena kutulutsa mpweya.
- Kutaya mphamvu kosasinthika: Kuwononga mkati mwa batri ndikufupikitsa moyo wa batri.
BMS imalimbana ndi izi kudzera pakuwunika kwamagetsi kosalekeza. Imatsata ndendende mphamvu yamagetsi ya cell iliyonse mkati mwa paketiyo pogwiritsa ntchito masensa aku board. Ngati magetsi amtundu uliwonse akwera kupitirira malire otetezedwa, BMS imagwira ntchito mwachangu polamula kuti chiwongolero chamagetsi chizidulira. Kudutsidwa mwachangu kwa mphamvu yolipiritsa ndiye njira yoyamba yodzitchinjiriza kuti isaperekedwe mochulukira, kupewa kulephera kowopsa. Kuphatikiza apo, mayankho apamwamba a BMS amaphatikiza ma aligorivimu kuti azitha kuyendetsa bwino magawo oyitanitsa.
Ntchito Yofunika Kwambiri Yopewera Kutaya Kutaya Kwambiri
Mosiyana ndi zimenezo, kutulutsa batri mozama kwambiri - pansi pa malo ake ochepetsera magetsi - kumabweretsanso zoopsa. Kutaya kwambiri m'mabatire a LFP kungayambitse:
- Kuchuluka kwamphamvu kumazirala: Kutha kukhala ndi mphamvu zonse kumachepa kwambiri.
- Kusakhazikika kwamankhwala amkati: Kupangitsa kuti batire ikhale yosatetezeka kuti ikulitsidwenso kapena kugwiritsidwa ntchito mtsogolo.
- Kusintha kwa ma cell : M'mapaketi okhala ndi ma cell ambiri, ma cell ofooka amatha kuthamangitsidwa kupita ku reverse polarity, ndikupangitsa kuwonongeka kosatha.
Apa, BMS imagwiranso ntchito ngati woyang'anira tcheru, makamaka kudzera pakuwunika kolondola kwa state-of-charge (SOC) kapena kuzindikira kwamagetsi otsika. Imalondola kwambiri mphamvu yomwe ilipo ya batri. Pamene mulingo wa voteji wa selo iliyonse ukuyandikira poyambira otsika-voltage, BMS imayambitsa discharge circuit cutoff. Izi zimayimitsa mphamvu yokoka kuchokera ku batri nthawi yomweyo. Zomangamanga zina zamtundu wa BMS zimagwiritsanso ntchito njira zochepetsera katundu, kuchepetsa mwanzeru zotengera mphamvu zosafunikira kapena kulowa munjira yamphamvu ya batri, kuti mutalikitse magwiridwe antchito ofunikira ndikuteteza ma cell. Njira yopewera kutulutsa kwakuya iyi ndiyofunikira pakukulitsa moyo wa batri, ndikusunga kudalirika kwadongosolo lonse.
Chitetezo Chophatikizidwa: Core of Battery Safety
Kuteteza kokwanira komanso kutulutsa kopitilira muyeso si ntchito imodzi koma njira yophatikizika mkati mwa BMS yamphamvu. Makina amakono owongolera mabatire amaphatikiza kuthamanga kwambiri ndi ma aligorivimu otsogola amagetsi anthawi yeniyeni komanso kutsatira kwaposachedwa, kuyang'anira kutentha, komanso kuwongolera kwamphamvu. Njira yachitetezo cha batri yonseyi imatsimikizira kuzindikirika mwachangu komanso kuchitapo kanthu mwachangu pazowopsa. Kuteteza ndalama za batri yanu kumadalira machitidwe anzeru awa.
