Nkhani - Controller Voltage Range: Chinsinsi cha Kugwirizana kwa Mabatire a EV & BMS

Eni magalimoto ambiri amagetsi amadabwa kuti n’chiyani chimachititsa kuti magetsi a galimoto yawo agwire ntchito - kodi ndi batire kapena injini? Chodabwitsa n’chakuti, yankho lili pa chowongolera zamagetsi. Gawo lofunika kwambiri limeneli limakhazikitsa kuchuluka kwa magetsi omwe amayendetsa mabatire komanso momwe makinawo amagwirira ntchito.

Ma voltages okhazikika a EV akuphatikizapo makina a 48V, 60V, ndi 72V, aliwonse ali ndi magawo enaake ogwirira ntchito:

Makina a 48V nthawi zambiri amagwira ntchito pakati pa 42V ndi 60V
Makina a 60V amagwira ntchito mkati mwa 50V-75V
Makina a 72V amagwira ntchito ndi ma range a 60V-89V

Olamulira apamwamba amatha kuthana ndi ma voltage opitilira 110V, zomwe zimapangitsa kuti zikhale zosavuta.

Kulekerera kwa mphamvu yamagetsi ya chowongolera kumakhudza mwachindunji kuyanjana kwa batri ya lithiamu kudzera mu Battery Management System (BMS). Mabatire a Lithium amagwira ntchito mkati mwa nsanja zinazake zamagetsi zomwe zimasinthasintha panthawi ya chaji/kutulutsa. Mphamvu yamagetsi ya batri ikapitirira malire apamwamba a chowongolera kapena ikatsika pansi pa malire ake otsika, galimotoyo siyamba - mosasamala kanthu za momwe chaji yeniyeni ya batri ilili.

Taganizirani zitsanzo izi zenizeni:

Batire ya 72V lithium nickel-manganese-cobalt (NMC) yokhala ndi maselo 21 imafika pa 89.25V ikadzadza mokwanira, ndikutsika kufika pa 87V pambuyo poti magetsi a circuit atsika. Mofananamo, batire ya 72V lithium iron phosphate (LiFePO4) yokhala ndi maselo 24 imafika pa 87.6V ikadzadza mokwanira, ndikutsika kufika pa 82V. Ngakhale kuti zonsezi zimakhala mkati mwa malire apamwamba a controller, mavuto amayamba mabatire akamayandikira kutuluka.

Vuto lalikulu limachitika pamene mphamvu ya batri yatsika pansi pa malire ochepera a wowongolera chitetezo cha BMS chisanayambe kugwira ntchito. Pankhaniyi, njira zotetezera za wowongolera zimaletsa kutuluka kwa galimotoyo, zomwe zimapangitsa kuti galimotoyo isagwire ntchito ngakhale batriyo ikadali ndi mphamvu yogwiritsidwa ntchito.

Ubale uwu ukuwonetsa chifukwa chake kasinthidwe ka batri kayenera kugwirizana ndi zomwe wolamulira akufuna. Chiwerengero cha maselo a batri motsatizana chimadalira mwachindunji kuchuluka kwa magetsi a wolamulira, pomwe kuchuluka kwa magetsi a wolamulira kumatsimikiza zomwe BMS ikufuna. Kudalirana kumeneku kukuwonetsa chifukwa chake kumvetsetsa magawo a wolamulira ndikofunikira pakupanga makina oyenera a EV.

Pofuna kuthetsa mavuto, pamene batire ikuwonetsa mphamvu yotulutsa koma singathe kuyambitsa galimoto, magawo ogwirira ntchito a wowongolera ayenera kukhala malo oyamba ofufuzira. Dongosolo Loyang'anira Mabatire ndi wowongolera ayenera kugwira ntchito mogwirizana kuti atsimikizire kuti ntchitoyo ndi yodalirika. Pamene ukadaulo wa EV ukusintha, kuzindikira ubale wofunikirawu kumathandiza eni ake ndi akatswiri kukonza magwiridwe antchito ndikupewa mavuto omwe amafanana.
