Charger yamagalimoto (OBC)
Chaja yomwe ili m'bwalo ndiyomwe imapangitsa kuti magetsi azisintha kuti aziwongolera batire lamagetsi.
Pakadali pano, magalimoto amagetsi otsika kwambiri komanso magalimoto amagetsi ang'onoang'ono a A00 amakhala ndi ma charger a 1.5kW ndi 2kW, ndipo magalimoto opitilira A00 ali ndi ma charger a 3.3kW ndi 6.6kW.
Ma AC ambiri amalipira magalimoto amalonda 380Vmagawo atatu mafakitale magetsi, ndi mphamvu pamwamba 10kW.
Malinga ndi kafukufuku wa Gaogong Electric Vehicle Research Institute (GGII), mu 2018, kufunikira kwa ma charger amagetsi atsopano ku China kudafika ma seti 1.220,700, ndikukula kwa chaka ndi 50.46%.
Malinga ndi momwe msika umagwirira ntchito, ma charger okhala ndi mphamvu zokulirapo kuposa 5kW amakhala ndi gawo lalikulu pamsika, pafupifupi 70%.
Mabizinesi akuluakulu akunja omwe amapanga charger yamagalimoto ndi Kesida,Emerson, Valeo, Infineon, Bosch ndi mabizinesi ena ndi zina zotero.
OBC wamba nthawi zambiri imakhala yozungulira mphamvu (zigawo zazikuluzikulu zikuphatikiza PFC ndi DC/DC) ndi gawo lowongolera (monga momwe tawonetsera pansipa).
Pakati pawo, ntchito yaikulu ya dera lamagetsi ndikusintha ma alternating current kukhala okhazikika;Kuwongolera dera makamaka kukwaniritsa kulankhulana ndi batire, ndipo malinga ndi kufunika kulamulira mphamvu pagalimoto dera linanena bungwe voteji zina ndi panopa.
Ma diode ndi ma switching chubu (IGBTs, MOSFETs, etc.) ndi zida zazikulu za semiconductor zomwe zimagwiritsidwa ntchito mu OBC.
Ndi kugwiritsa ntchito zida zamphamvu za silicon carbide, kutembenuka kwa OBC kumatha kufika 96%, ndipo kachulukidwe ka mphamvu amatha kufikira 1.2W/cc.
Kuchita bwino kukuyembekezeka kukwera mpaka 98% mtsogolomo.
Mbiri yodziwika bwino ya charger yamagalimoto:
Kuwongolera kutentha kwa mpweya wozizira
Mu firiji yamagetsi yamagalimoto amagetsi, chifukwa mulibe injini, kompresa iyenera kuyendetsedwa ndi magetsi, ndipo mpukutu wamagetsi wamagetsi ophatikizidwa ndi mota yamagetsi ndi wowongolera amagwiritsidwa ntchito kwambiri pakadali pano, omwe ali ndi mphamvu yayikulu komanso yotsika. mtengo.
Kuchulukitsidwa kwamphamvu ndiye njira yayikulu yachitukukompukutu compressors mtsogolomu.
Kutenthetsa kwa mpweya wa galimoto yamagetsi ndikoyenera kusamala.
Chifukwa cha kusowa kwa injini ngati gwero la kutentha, magalimoto amagetsi nthawi zambiri amagwiritsa ntchito PTC thermistors kutenthetsa cockpit.
Ngakhale kuti njira yothetsera vutoli ndi yofulumira komanso yodziwikiratu nthawi zonse, teknolojiyi ndi yokhwima kwambiri, koma vuto ndiloti mphamvu yogwiritsira ntchito mphamvu ndi yaikulu, makamaka m'malo ozizira pamene kutentha kwa PTC kungayambitse kuposa 25% ya kupirira kwa magalimoto amagetsi.
Choncho, kutentha mpope mpweya wofewetsa luso pang'onopang'ono kukhala njira ina, amene angapulumutse pafupifupi 50% ya mphamvu kuposa PTC Kutentha chiwembu pa kutentha yozungulira pafupifupi 0 ° C.
Pankhani ya mafiriji, bungwe la European Union la "Automotive Air Conditioning System Directive" lalimbikitsa kupanga mafiriji atsopano.makometsedwe a mpweya, ndi kugwiritsa ntchito refrigerant ya CO2 (R744) yokhala ndi GWP 0 ndi ODP 1 yawonjezeka pang'onopang'ono.
Poyerekeza ndi HFO-1234yf, HFC-134a ndi refrigerants ena okha -5 madigiri pamwamba ndi zabwino kuzirala kwenikweni, CO2 pa -20 ℃ Kutentha mphamvu Mwachangu chiŵerengero akadali kufika 2, ndi tsogolo la galimoto yamagetsi kutentha mpope mpweya mphamvu dzuwa. ndiye chisankho chabwino kwambiri.
Table : Kapangidwe kazinthu zamafiriji
Ndi chitukuko cha magalimoto amagetsi komanso kuwongolera kwa mtengo wa kasamalidwe ka matenthedwe, malo amsika owongolera matenthedwe agalimoto yamagetsi ndiambiri.
