Car charger (OBC)
I-on-board charger ine basa rekushandura alternating current kuti itungamire ikozvino kuti ichaja bhatiri remagetsi.
Parizvino, mota dzemagetsi dzakaderera uye A00 mini mota dzemagetsi dzakashongedzerwa ne1.5kW uye 2kW majaja, uye anopfuura A00 mota dzevatakuri dzakashongedzerwa 3.3kW uye 6.6kW majaja.
Yakawanda yekuchaja kweAC yemotokari dzekutengesa inoshandisa 380Vmatatu-chikamu maindasitiri magetsi, uye simba riri pamusoro 10kW.
Zvinoenderana nedata rekutsvagisa reGaogong Electric Vehicle Research Institute (GGII), muna 2018, kudiwa kwemotokari nyowani pabhodhi majaja muChina kwakasvika 1.220,700 seti, nekukura-pagore kwe50.46%.
Kubva pakuona kwechimiro chemusika wayo, majaja ane simba rekubuda rakakura kupfuura 5kW anotora chikamu chikuru chemusika, angangoita makumi manomwe%.
Mabhizinesi makuru ekunze anogadzira charger yemotokari ndiKesida,Emerson, Valeo, Infineon, Bosch uye mamwe mabhizinesi uye zvichingodaro.
Iyo yakajairika OBC inonyanya kuumbwa neyemagetsi dunhu (yakakosha zvikamu zvinosanganisira PFC uye DC/DC) uye yekudzora dunhu (sezvinoratidzwa pazasi).
Pakati pavo, basa guru remagetsi emagetsi nderekushandura ikozvino kuchinja kune yakagadzikana yakananga ikozvino;Iyo control circuit inonyanya kuzadzisa kutaurirana nebhatiri, uye zvinoenderana nezvinodiwa kudzora simba dhiraivha redunhu rinoburitsa imwe voltage uye yazvino.
Diodes uye switching chubhu (IGBTs, MOSFETs, nezvimwewo) ndiwo makuru emagetsi semiconductor zvishandiso zvinoshandiswa muOBC.
Nekushandiswa kwesilicon carbide magetsi emagetsi, shanduko yeOBC inogona kusvika 96%, uye simba remagetsi rinogona kusvika 1.2W/cc.
Iko kushanda kunotarisirwa kuwedzera kuwedzera kusvika 98% mune ramangwana.
Yakajairika topology yemotokari charger:
Air conditioning thermal management
Mufiriji system yemagetsi emagetsi emhepo, nekuti hapana injini, iyo compressor inoda kufambiswa nemagetsi, uye mupumburu wemagetsi compressor wakabatanidzwa nedhiraivha mota uye controller unoshandiswa zvakanyanya parizvino, ine yakakwira vhoriyamu kunyatsoshanda uye yakaderera. mutengo.
Kuwedzera kudzvanywa ndiyo huru yekusimudzira kutungamira kwescroll compressors mune ramangwana.
Motokari yemagetsi airconditioning kudziyisa ndiyo yakanyatsokodzera kutariswa.
Nekuda kwekushaikwa kweinjini senzvimbo yekupisa, mota dzemagetsi dzinowanzo shandisa PTC thermistors kupisa cockpit.
Kunyangwe iyi mhinduro iri kukurumidza uye inongogara tembiricha tekinoroji, iyo tekinoroji yakawedzera kukura, asi chakashata ndechekuti simba rekushandisa rakakura, kunyanya munzvimbo inotonhora apo kupisa kwePTC kunogona kukonzera kupfuura 25% yekutsungirira kwemotokari dzemagetsi.
Naizvozvo, tekinoroji yekupisa yepombi yemhepo yekumisikidza zvishoma nezvishoma yave imwe mhinduro, inogona kuchengetedza ingangoita 50% yesimba pane PTC yekudziya chirongwa pane ambient tembiricha inosvika 0 ° C.
Panyaya dzemafiriji, European Union's "Automotive Air Conditioning System Directive" yakurudzira kugadzirwa kwemafiriji matsva.air conditioning, uye kushandiswa kwezvakatipoteredza refrigerant CO2 (R744) neGWP 0 uye ODP 1 yakawedzera zvishoma nezvishoma.
Kuenzaniswa neHFO-1234yf, HFC-134a uye mamwe mafiriji chete pa -5 madhigirii ari pamusoro ane yakanaka kutonhora mhedzisiro, CO2 pa -20 ℃ kupisa kwesimba rekushandisa simba rinogona kuramba richisvika 2, ndiro remangwana remagetsi emotokari kupisa pombi yemhepo inogadzirisa simba. ndiyo yakanakisa sarudzo.
Tafura: Mafambiro ekuvandudza emidziyo yefiriji
Nekuvandudzwa kwemotokari dzemagetsi uye nekuvandudzwa kwekukosha kweiyo thermal management system, nzvimbo yemusika yemagetsi mota yekudziya yekudziya yakafara.
