M'dziko la mabatire lomwe likukula mofulumira, Lithium Iron Phosphate (LFP) yapeza mphamvu zambiri chifukwa cha chitetezo chake chabwino komanso moyo wautali. Komabe, kuyang'anira magwero amagetsi awa mosamala kumakhalabe kofunika kwambiri. Pakati pa chitetezochi pali Battery Management System, kapena BMS. Dongosolo loteteza laukadaulo ili limagwira ntchito yofunika kwambiri, makamaka popewa zinthu ziwiri zomwe zingawononge komanso zoopsa: chitetezo champhamvu kwambiri ndi chitetezo champhamvu kwambiri. Kumvetsetsa njira zotetezera mabatirezi ndikofunikira kwa aliyense amene amadalira ukadaulo wa LFP posungira mphamvu, kaya m'nyumba kapena m'mafakitale akuluakulu.
Chifukwa Chake Chitetezo Chowonjezera Ndi Chofunikira pa Mabatire a LFP
Kuchaja kwambiri kumachitika pamene batire ikupitiliza kulandira mphamvu kupitirira momwe imachajidwira mokwanira. Pa mabatire a LFP, izi si vuto lokha la magwiridwe antchito—Ndi ngozi yoopsa. Mphamvu yamagetsi yochulukirapo panthawi yodzaza mphamvu ingayambitse:
- Kukwera kwa kutentha mwachangu: Izi zimathandizira kuwonongeka kwa nthaka ndipo, nthawi zina, zimatha kuyambitsa kutayika kwa kutentha.
- Kuchulukana kwa mphamvu mkati: Kumayambitsa kutuluka kwa ma electrolyte kapena kutulutsa mpweya.
- Kutayika kwa mphamvu yosasinthika: Kuwononga kapangidwe ka mkati mwa batri ndikufupikitsa nthawi ya batri.
BMS imalimbana ndi izi kudzera mu kuyang'anira magetsi mosalekeza. Imatsata molondola magetsi a selo lililonse mkati mwa paketi pogwiritsa ntchito masensa omwe ali mkati. Ngati magetsi aliwonse a selo akwera kupitirira malire otetezedwa omwe adakhazikitsidwa kale, BMS imachitapo kanthu mwachangu polamula kuti magetsi azitha kuchotsedwa. Kudula mphamvu yochaja nthawi yomweyo ndiye chitetezo chachikulu kuti chisadzaze kwambiri, zomwe zimaletsa kulephera kwakukulu. Kuphatikiza apo, njira zamakono za BMS zimaphatikizapo ma algorithms kuti azisamalira magawo ochaja mosamala.
Udindo Wofunika Kwambiri Wopewera Kutuluka Mopitirira Muyeso
Mosiyana ndi zimenezi, kutulutsa batire mozama kwambiri—komwe kuli pansi pa malo oyenera ochotsera magetsi—kumabweretsanso zoopsa zazikulu. Kutulutsa madzi ambiri m'mabatire a LFP kungayambitse:
- Kuchepa kwa mphamvu: Kutha kugwira ntchito yonse kumachepa kwambiri.
- Kusakhazikika kwa mankhwala mkati: Kupangitsa batri kukhala losatetezeka pakuyiyikanso kapena kugwiritsa ntchito mtsogolo.
- Kusinthika kwa maselo: Mu ma pack a maselo ambiri, maselo ofooka amatha kuyendetsedwa mu polarity yobwerera m'mbuyo, zomwe zimapangitsa kuwonongeka kosatha.
Apa, BMS imagwiranso ntchito ngati woyang'anira maso, makamaka kudzera mu kuyang'anira molondola (SOC) kapena kuzindikira mphamvu zochepa. Imatsata bwino mphamvu zomwe batire ili nazo. Pamene mphamvu yamagetsi ya selo iliyonse ikuyandikira malire otsika, BMS imayambitsa kudulidwa kwa dera lotulutsa mphamvu. Izi zimayimitsa nthawi yomweyo mphamvu yochokera ku batire. Mapangidwe ena apamwamba a BMS amagwiritsanso ntchito njira zochepetsera mphamvu, mwanzeru kuchepetsa mphamvu zosafunikira kapena kulowa mu batire yotsika mphamvu kuti iwonjezere ntchito yofunikira ndikuteteza maselo. Njira yopewera kutulutsa mphamvu kwambiri iyi ndiyofunikira pakukulitsa moyo wa batire ndikusunga kudalirika kwa dongosolo lonse.
Chitetezo Chogwirizana: Pakati pa Chitetezo cha Batri
Chitetezo chogwira ntchito cha overcharge ndi over-discharge si ntchito imodzi yokha koma njira yogwirizana mkati mwa BMS yolimba. Machitidwe amakono oyendetsera batri amaphatikiza kukonza mwachangu kwambiri ndi ma algorithms apamwamba kuti azitha kutsatira magetsi nthawi yeniyeni komanso nthawi yeniyeni, kuyang'anira kutentha, komanso kuwongolera kwamphamvu. Njira yotetezeka ya batri yonseyi imatsimikizira kuzindikira mwachangu komanso kuchitapo kanthu mwachangu motsutsana ndi zinthu zomwe zingakhale zoopsa. Kuteteza ndalama zomwe mumayika pa batri yanu kumadalira machitidwe anzeru oyendetsera awa.
