Ishaja yemoto (OBC)
Ishaja esebhodini inesibopho sokuguqula i-alternating current ukuthi iqondise yamanje ukuze ishaje ibhethri lamandla.
Njengamanje, izimoto zikagesi ezihamba ngesivinini esiphansi kanye nezimoto ezisebenza ngogesi ezincane i-A00 zihlome kakhulu ngamashaja angu-1.5kW no-2kW, kanti izimoto ezithwala abantu ezingaphezu kuka-A00 zifakelwe amashaja angu-3.3kW no-6.6kW.
Iningi lokushaja kwe-AC kwezimoto zokuhweba ezisetshenziswayo 380Vugesi wezimboni wezigaba ezintathu, futhi amandla angaphezu kuka-10kW.
Ngokusho kwedatha yocwaningo ye-Gaogong Electric Vehicle Research Institute (GGII), ngo-2018, isidingo samashaja emoto yamandla amasha ebhodini e-China sifinyelele amasethi angu-1.220,700, ngezinga lokukhula konyaka nonyaka lika-50.46%.
Ngokombono wesakhiwo sayo semakethe, amashaja anamandla okukhipha angaphezu kuka-5kW athatha ingxenye enkulu yemakethe, cishe u-70%.
Amabhizinisi amakhulu angaphandle akhiqiza ishaja yemoto yiKesida,Emerson, Valeo, Infineon, Bosch kanye namanye amabhizinisi nokunye.
I-OBC evamile yakhiwa ngokuyinhloko isekethe yamandla (izingxenye eziyinhloko zifaka i-PFC ne-DC/DC) kanye nesekhethi yokulawula (njengoba kuboniswe ngezansi).
Phakathi kwabo, umsebenzi oyinhloko wesifunda samandla ukuguqula i-alternating current ibe yamanje eqondile eqondile; Isifunda sokulawula siwukufinyelela ukuxhumana nebhethri, futhi ngokusho kwesidingo sokulawula ukuphuma kwesekethe yedrayivu yamandla i-voltage ethile kanye namanje.
Ama-Diode namashubhu okushintsha (i-IGBTs, ama-MOSFET, njll.) angamadivayisi ayinhloko we-semiconductor yamandla asetshenziswa ku-OBC.
Ngokusetshenziswa kwemishini yamandla e-silicon carbide, ukusebenza kahle kokuguqulwa kwe-OBC kungafinyelela ku-96%, futhi ukuminyana kwamandla kungafinyelela ku-1.2W/cc.
Ukusebenza kahle kulindeleke ukuthi kuqhubeke kukhuphuke kuye kuma-98% esikhathini esizayo.
I-topology ejwayelekile yeshaja yemoto:
Ukuphathwa kokushisa kwe-air conditioning
Ohlelweni lwesiqandisi se-air conditioning yemoto kagesi, ngenxa yokuthi ayikho injini, i-compressor idinga ukushayelwa ugesi, futhi i-compressor kagesi yokuskrola ehlanganiswe ne-drive motor kanye nesilawuli isetshenziswa kabanzi njengamanje, esebenza kahle kakhulu futhi iphansi. izindleko.
Ukwenyuka kwengcindezi kuyisiqondiso esikhulu sokuthuthukiswa kweskrola ama-compressors esikhathini esizayo.
Imoto kagesi yokushisisa i-air conditioning ifaneleka kakhulu ukunakwa.
Ngenxa yokuntuleka kwenjini njengomthombo wokushisa, izimoto zikagesi ngokuvamile zisebenzisa ama-thermistors e-PTC ukushisa i-cockpit.
Nakuba lesi sixazululo sishisa ngokuzenzakalelayo futhi sisebenza ngokuzenzakalelayo, ubuchwepheshe buvuthwe kakhulu, kodwa okubi ukuthi ukusetshenziswa kwamandla kukhulu, ikakhulukazi endaweni ebandayo lapho ukushisa kwe-PTC kungase kubangele ngaphezu kwe-25% yokukhuthazela kwezimoto zikagesi.
Ngakho-ke, ubuchwepheshe be-heat pump air conditioning buye baba yisixazululo esingesinye, esingasindisa cishe u-50% wamandla kunohlelo lokushisa lwe-PTC endaweni yokushisa engaba ngu-0 ° C.
Mayelana neziqandisi, "I-Automotive Air Conditioning System Directive" ye-European Union ikhuthaze ukwakhiwa kweziqandisi ezintsha zeumshini ongenisa umoya, kanye nokufakwa kwesiqandisi esivumelana nemvelo i-CO2 (R744) esine-GWP 0 ne-ODP 1 kuye kwanda kancane kancane.
Uma kuqhathaniswa ne-HFO-1234yf, i-HFC-134a nezinye iziqandisi eziku--5 degrees ngenhla kuphela zinomphumela omuhle wokupholisa, i-CO2 ku- -20 ℃ isilinganiso sokusebenza kahle kwamandla okufudumeza isengafinyelela ku-2, ikusasa lephampu yokushisa yemoto kagesi ye-air conditioning energy ukusebenza kahle. kuyisinqumo esingcono kakhulu.
Ithebula : Ukuthambekela kokuthuthukiswa kwezinto zesiqandisi
Ngokuthuthukiswa kwezimoto zikagesi kanye nokuthuthukiswa kwenani lesistimu yokulawula ukushisa, indawo yemakethe yokuphathwa kokushisa kwemoto kagesi ibanzi.
