Nkhani - Mtundu wa Voltage Wowongolera: Chinsinsi cha EV Battery Compatibility & BMS

Eni ake ambiri a EV amadabwa chomwe chimatsimikizira mphamvu yagalimoto yawo - ndi batire kapena mota? Chodabwitsa n'chakuti yankho liri ndi wolamulira wamagetsi. Gawo lofunikirali limakhazikitsa kuchuluka kwamagetsi komwe kumapangitsa kuti batire igwirizane komanso magwiridwe antchito onse.

Ma voltages okhazikika a EV amaphatikiza makina a 48V, 60V, ndi 72V, iliyonse ili ndi magawo ake ogwiritsira ntchito:

Machitidwe a 48V nthawi zambiri amagwira ntchito pakati pa 42V-60V
60V machitidwe amagwira ntchito mkati mwa 50V-75V
Machitidwe a 72V amagwira ntchito ndi 60V-89V

Olamulira apamwamba amatha kugwira ngakhale ma voltages opitilira 110V, opatsa kusinthasintha kwakukulu.

Kulekerera kwamagetsi kwa owongolera kumakhudza mwachindunji kuyanjana kwa batri la lithiamu kudzera mu Battery Management System (BMS) . Mabatire a lithiamu amagwira ntchito m'mapulatifomu enaake omwe amasinthasintha nthawi yamalipiro / kutulutsa. Pamene mphamvu ya batri idutsa malire apamwamba a wolamulira kapena kugwera pansi pa malo ake otsika, galimotoyo siidzayamba - mosasamala kanthu za momwe batire ilili.

Taganizirani zitsanzo zenizeni izi:

Batire ya 72V lithiamu nickel-manganese-cobalt (NMC) yokhala ndi ma cell 21 imafika ku 89.25V ikayatsidwa kwathunthu, kutsika mpaka pafupifupi 87V pambuyo pakutsika kwamagetsi ozungulira. Mofananamo, batire ya 72V lithiamu iron phosphate (LiFePO4) yokhala ndi maselo 24 imakwaniritsa 87.6V pamalipiro athunthu, ikucheperachepera mpaka 82V. Ngakhale kuti onse amakhalabe m'maleredwe apamwamba a olamulira, mavuto amadza pamene mabatire akuyandikira kutulutsa.

Vuto lofunikira limachitika mphamvu ya batri ikatsika pansi pamlingo wocheperako chitetezo cha BMS chisanayambe. Munthawi imeneyi, njira zotetezera zowongolera zimalepheretsa kutulutsa, zomwe zimapangitsa kuti galimoto isagwire ntchito ngakhale batire ikadali ndi mphamvu zogwiritsidwa ntchito.

Ubalewu ukuwonetsa chifukwa chake kasinthidwe ka batri kuyenera kugwirizana ndi zomwe wowongolera. Kuchuluka kwa ma cell a batire pamndandanda kumadalira mwachindunji kuchuluka kwa ma voltage a controller, pomwe mavoti apano a owongolera amatsimikizira zomwe BMS ili nazo. Kudalirana uku kukuwonetsa chifukwa chake kumvetsetsa magawo owongolera ndikofunikira pamapangidwe oyenera a EV system.

Kuti muthane ndi mavuto, batire ikawonetsa mphamvu yakutulutsa koma osayatsa galimoto, magawo ogwiritsira ntchito owongolera ayenera kukhala malo oyamba ofufuzira. Battery Management System ndi wowongolera ayenera kugwira ntchito mogwirizana kuti awonetsetse kuti akugwira ntchito yodalirika. Pamene ukadaulo wa EV ukusintha, kuzindikira ubale wofunikirawu kumathandiza eni ake ndi akatswili kukhathamiritsa magwiridwe antchito ndikupewa zovuta zomwe zimagwirizana.
