Amashanyarazi (OBC)
Amashanyarazi ari mu ndege ashinzwe guhindura insimburangingo kugirango yerekane amashanyarazi kugirango yishyure bateri.
Kugeza ubu, ibinyabiziga by’amashanyarazi yihuta hamwe n’imodoka ya A00 mini y’amashanyarazi bifite ibikoresho cyane cyane 1.5kW na 2kW, kandi imodoka zitwara abagenzi zirenga A00 zifite ibikoresho bya 3.3kW na 6.6kW.
Ibyinshi muri AC kwishyuza ibinyabiziga byubucuruzi bikoresha 380Vamashanyarazi y'ibyiciro bitatu, kandi ingufu ziri hejuru ya 10kW.
Dukurikije imibare y’ubushakashatsi bw’ikigo cy’ubushakashatsi cy’amashanyarazi cya Gaogong (GGII), mu mwaka wa 2018, icyifuzo cy’imodoka nshya z’ingufu zishyirwa mu ndege mu Bushinwa cyageze ku maseti 1.220.700, aho umwaka ushize wiyongereyeho 50.46%.
Urebye imiterere yisoko ryayo, charger zifite ingufu zirenze 5kW zifata igice kinini cyisoko, hafi 70%.
Ibigo bikuru by’amahanga bitanga amashanyarazi ni Kesida,Emerson, Valeo, Infineon, Bosch nibindi bigo nibindi.
Ubusanzwe OBC igizwe ahanini numuzunguruko w'amashanyarazi (ibice byingenzi birimo PFC na DC / DC) hamwe numuzunguruko (nkuko bigaragara hano).
Muri byo, umurimo wingenzi wumuzunguruko w'amashanyarazi ni uguhinduranya imiyoboro ihindagurika; Igenzura ryumuzunguruko ahanini ni ukugera ku itumanaho na bateri, kandi ukurikije icyifuzo cyo kugenzura amashanyarazi asohora amashanyarazi n’umuriro runaka.
Diode no guhinduranya imiyoboro (IGBTs, MOSFETs, nibindi) nibikoresho nyamukuru byingufu zikoreshwa muri OBC.
Hamwe nogukoresha ibikoresho byingufu za silicon karbide, imikorere ya OBC irashobora kugera kuri 96%, naho ubwinshi bwamashanyarazi bukagera kuri 1.2W / cc.
Biteganijwe ko imikorere izakomeza kwiyongera kugera kuri 98% mugihe kizaza.
Ubusanzwe topologiya yumuriro wibinyabiziga ：
Gucunga umuyaga
Muri sisitemu yo gukonjesha ibinyabiziga bikoresha amashanyarazi, kubera ko nta moteri ihari, compressor igomba gutwarwa n’amashanyarazi, kandi compressor yamashanyarazi yinjizwamo na moteri ya moteri na mugenzuzi ikoreshwa cyane muri iki gihe, ifite ubushobozi buke kandi buke igiciro.
Kongera igitutu nicyerekezo nyamukuru cyiterambere cyaimizingo ejo hazaza.
Gushyushya ibinyabiziga bikoresha amashanyarazi birasa nkaho bikwiye kwitabwaho.
Bitewe no kubura moteri nkisoko yubushyuhe, ibinyabiziga byamashanyarazi mubisanzwe bikoresha ubushyuhe bwa PTC kugirango bishyushya cockpit.
Nubwo iki gisubizo cyihuta kandi cyikora ubushyuhe burigihe, ikoranabuhanga rirakuze, ariko ikibi nuko ingufu zikoreshwa ari nini, cyane cyane mubihe bikonje mugihe ubushyuhe bwa PTC bushobora gutera hejuru ya 25% kwihanganira ibinyabiziga byamashanyarazi.
Kubwibyo, tekinoroji ya pompe yubushyuhe bwahindutse buhoro buhoro igisubizo kindi, gishobora kuzigama ingufu zingana na 50% kuruta gahunda yo gushyushya PTC kubushyuhe bwibidukikije bwa 0 ° C.
Ku bijyanye na firigo, "Amabwiriza ya Automotive Air Conditioning System Directive" y’ubumwe bw’ibihugu by’i Burayi yateje imbere iterambere rya firigo nshya kuriubukonje, hamwe no gukoresha firigo itangiza ibidukikije CO2 (R744) hamwe na GWP 0 na ODP 1 yagiye yiyongera buhoro buhoro.
Ugereranije na HFO-1234yf, HFC-134a hamwe nandi ma firigo gusa kuri dogere -5 hejuru gusa bigira ingaruka nziza yo gukonjesha, CO2 kuri -20 ratio igipimo cy’ingufu zo gushyushya kirashobora kugera kuri 2, ni ejo hazaza h’ibinyabiziga bikoresha amashanyarazi pompe ihumeka neza ni ihitamo ryiza.
Imbonerahamwe: Iterambere ryibikoresho bya firigo
Hamwe no guteza imbere ibinyabiziga byamashanyarazi no kuzamura agaciro ka sisitemu yo gucunga amashyuza, umwanya w isoko ryimicungire yubushyuhe bwamashanyarazi ni nini.
