Nkhani - Kutayika kwa Mabatire a Lithium a M'nyengo Yachisanu? Malangizo Ofunika ndi Dongosolo Loyang'anira Mabatire

Pamene kutentha kukutsika, eni magalimoto amagetsi (EV) nthawi zambiri amakumana ndi vuto lokhumudwitsa: kuchepa kwa mabatire a lithiamu. Nyengo yozizira imachepetsa kugwira ntchito kwa mabatire, zomwe zimapangitsa kuti magetsi azizimitsidwa mwadzidzidzi komanso kuti mtunda waufupi ukhale wautali—makamaka kumpoto. Mwamwayi, ndi kukonza bwino komanso kudalirika.Dongosolo Loyang'anira Mabatire (BMS)Mavutowa akhoza kuchepetsedwa bwino. Pansipa pali malangizo otsimikizika oteteza mabatire a lithiamu ndikusunga magwiridwe antchito m'nyengo yozizira ino.

Choyamba, gwiritsani ntchito mafunde ochaja pang'onopang'ono. Kutentha kochepa kumachepetsa kuyenda kwa ma ion mkati mwa mabatire a lithiamu. Kugwiritsa ntchito mafunde okwera (1C kapena kupitirira apo) monga momwe zimakhalira nthawi yachilimwe kumapangitsa kuti mphamvu yosalowa m'thupi isanduke kutentha, zomwe zimaika pachiwopsezo kutupa ndi kuwonongeka kwa batri. Akatswiri amalimbikitsa kuti ma ion azitha kuyika pang'onopang'ono mu ma electrode, kuonetsetsa kuti azitha kutchaja mokwanira komanso kuchepetsa kuwonongeka. UbwinoDongosolo Loyang'anira Mabatire (BMS)imayang'anira mphamvu yochaja nthawi yeniyeni kuti ipewe kupitirira muyeso.

Chachiwiri, onetsetsani kuti kutentha kwa chaji kuli pamwamba pa 0℃. Chaji ili pansi pa zero imapanga lithiamu dendrites, zomwe zimawononga maselo a batri ndikuika pachiwopsezo chitetezo. Mayankho awiri othandiza: tengani mphindi 5-10 kuti mutenthetse batri musanayike, kapena ikani filimu yotenthetsera yolumikizidwa ndi BMS.BMS imayamba kugwira ntchito yokhakapena kuzima chotenthetsera pamene kutentha kwa batri kwafika pamlingo wokonzedweratu, kuchotsa machitidwe oopsa monga kutentha kwa moto wotseguka.

Chachitatu, chepetsani kuya kwa kutulutsa (DOD) kufika pa 80%. Kutulutsa mabatire a lithiamu mokwanira m'nyengo yozizira (100% DOD) kumayambitsa kuwonongeka kwamkati kosasinthika, zomwe zimapangitsa kuti pakhale mavuto a "magetsi enieni". Kuletsa kutulutsa pamene mphamvu ya 20% ikupitirirabe kumasunga batire pamalo okwera kwambiri, zomwe zimapangitsa kuti ikhale yokhazikika. BMS yodalirika imathandiza kuwongolera DOD mosavuta kudzera mu ntchito yake yoteteza kutulutsa.

Malangizo ena awiri owonjezera okonza: pewani kusunga nthawi yayitali kutentha kochepa—imikani ma EV m'magaraji kuti batire isatayike kwamuyaya. Pa mabatire osagwira ntchito, kuyitanitsa kowonjezera mpaka 50%-60% pa sabata ndikofunikira kwambiri. BMS yokhala ndi kuyang'anira patali imalola ogwiritsa ntchito kutsatira magetsi ndi kutentha nthawi iliyonse, kuonetsetsa kuti akukonza nthawi yake.

Dongosolo Loyang'anira Mabatire (BMS) lapamwamba kwambiri ndi lofunika kwambiri pa thanzi la batri m'nyengo yozizira. Zinthu zake zapamwamba, kuphatikizapo kuyang'anira nthawi yeniyeni komanso chitetezo chanzeru, zimateteza mabatire kuti asadzazidwe kapena kutayidwa bwino. Mwa kutsatira malangizo awa ndikugwiritsa ntchito BMS yodalirika, eni ake a EV amatha kusunga mabatire awo a lithiamu akugwira ntchito bwino nthawi yonse yozizira.
