Mabatire angapo a lithiamu amatha kulumikizidwa motsatizana kuti apange paketi ya batri, yomwe imatha kupereka mphamvu pazonyamula zosiyanasiyana komanso kuimbidwa nthawi zonse ndi charger yofananira. Mabatire a lithiamu safuna dongosolo lililonse loyang'anira batire (BMS) kulipira ndi kutulutsa. Ndiye chifukwa chiyani mabatire onse a lithiamu pamsika amawonjezera BMS? Yankho lake ndi chitetezo ndi moyo wautali.
Dongosolo loyang'anira mabatire a BMS (Battery Management System) limagwiritsidwa ntchito kuyang'anira ndikuwongolera kuyitanitsa ndi kutulutsa mabatire omwe amatha kuchangidwanso. Ntchito yofunika kwambiri ya lithiamu batire kasamalidwe dongosolo (BMS) ndi kuonetsetsa kuti mabatire kukhala mkati otetezeka ntchito malire ndi kuchitapo kanthu mwamsanga ngati aliyense batire ayamba kupitirira malire. BMS ikazindikira kuti voteji ndiyotsika kwambiri, imachotsa katunduyo, ndipo ngati voteji yakwera kwambiri, imachotsa charger. Iwonanso kuti selo lililonse mu paketi lili pamagetsi omwewo ndikuchepetsa mphamvu iliyonse yomwe ili yokwera kuposa ma cell ena. Izi zimatsimikizira kuti batire silifika ma voltages owopsa kapena otsika-zomwe nthawi zambiri zimayambitsa moto wa batri la lithiamu zomwe timaziwona m'nkhani. Imatha kuyang'anitsitsa kutentha kwa batri ndikuchotsa paketi ya batri isanatenthe kwambiri kuti igwire moto. Chifukwa chake, kasamalidwe ka batire ka BMS imalola batire kutetezedwa m'malo mongodalira pa charger yabwino kapena kugwiritsa ntchito moyenera.
Bwanji osatero't mabatire a lead-acid amafunikira kasamalidwe ka batire? Kapangidwe ka mabatire a lead-acid sangawotchere, kuwapangitsa kuti asagwire moto ngati pali vuto la kulipiritsa kapena kutulutsa. Koma chifukwa chachikulu ndichokhudzana ndi momwe batire imachitira ikakhala yokwanira. Mabatire a asidi amtovu amapangidwanso ndi maselo olumikizidwa motsatizana; ngati selo limodzi liri ndi ndalama zochulukirapo kuposa maselo ena, limangolola kuti zomwe zilipo panopa zidutse mpaka ma cell ena ali ndi mphamvu zokwanira, ndikusunga magetsi oyenera, ndi zina zotero. Mwanjira imeneyi, mabatire a lead-acid "amadzilinganiza" momwe akulipiritsa.
Mabatire a lithiamu ndi osiyana. Elekitirodi yabwino yamabatire a lithiamu omwe amatha kuwonjezeredwa nthawi zambiri amakhala lithiamu ion zakuthupi. Mfundo yake yogwirira ntchito imatsimikizira kuti panthawi yoperekera ndi kutulutsa, ma elekitironi a lithiamu adzathamangira kumbali zonse za ma elekitirodi abwino ndi oipa mobwerezabwereza. Ngati magetsi a selo limodzi amaloledwa kukhala apamwamba kuposa 4.25v (kupatulapo mabatire a lithiamu-voltage), mawonekedwe a anode microporous akhoza kugwa, zinthu zolimba za kristalo zimatha kukula ndikuyambitsa dera lalifupi, ndiyeno kutentha kudzawuka. mofulumira, potsirizira pake kumabweretsa moto. Batire ya lithiamu ikatha, mphamvuyi imakwera mwadzidzidzi ndipo imatha kufika pamlingo wowopsa. Ngati voteji ya selo linalake mu batire paketi ndi yokwera kuposa ya ma cell ena, cell iyi imafika pa voteji yowopsa poyamba pakuchangitsa. Pakadali pano, voteji yonse ya paketi ya batri sinafike pamtengo wonse, ndipo chojambulira sichidzasiya kuyitanitsa. . Chifukwa chake, ma cell omwe amafika pamagetsi owopsa amayamba kuyambitsa ngozi. Chifukwa chake, kuwongolera ndi kuyang'anira kuchuluka kwamagetsi a batire paketi sikokwanira kwa ma chemistries a lithiamu. BMS iyenera kuyang'ana mphamvu ya selo iliyonse yomwe imapanga paketi ya batri.
Chifukwa chake, kuonetsetsa chitetezo ndi moyo wautali wautumiki wa mapaketi a batri a lithiamu, dongosolo labwino komanso lodalirika la kasamalidwe ka batri la BMS likufunikadi.
