Imwe yeakakosha matekinoroji emagetsi matsva emagetsi mabhatiri emagetsi.Unhu hwemabhatiri hunosarudza mari yemotokari dzemagetsi kune rumwe rutivi, uye kutyaira kwemotokari yemagetsi kune imwe.Chinhu chakakosha chekugamuchirwa uye kugamuchirwa nekukurumidza.
Zvinoenderana nemaitiro ekushandisa, zvinodiwa uye mashandisirwo emabhatiri emagetsi, mhando dzekutsvagisa nekusimudzira mabhatiri emagetsi kumba nekune dzimwe nyika dzinenge: mabhatiri e-lead-acid, nickel-cadmium mabhatiri, nickel-metal hydride mabhatiri, lithium-ion mabhatiri, masero emafuta, nezvimwewo, pakati peiyo kuvandudzwa kwemabhatiri e-lithium-ion kunonyanya kutariswa.
Simba bhatiri rekugadzira kupisa maitiro
Iyo yekupisa sosi, kupisa kwekugadzira chiyero, bhatiri kupisa huwandu uye mamwe ane hukama ma parameter eiyo simba bhatiri module inowirirana zvakanyanya nehunhu hwebhatiri.Kupisa kunoburitswa nebhatiri kunoenderana nemakemikari, mechanical uye magetsi hunhu uye maitiro ebhatiri, kunyanya chimiro che electrochemical reaction.Simba rekupisa rinogadzirwa mubhatiri rinoita rinogona kuratidzwa nebhatiri rekuita kupisa Qr;iyo electrochemical polarization inokonzeresa kuti voltage chaiyo yebhatiri ibve pakuenzanisa kwayo magetsi emagetsi, uye kurasikirwa kwesimba kunokonzerwa nebhatiri polarization kunoratidzwa neQp.Pamusoro pekuita kwebhatiri kuenderera zvinoenderana nemaitiro equation, kune zvakare mamwe emativi maitiro.Maitikiro akajairika anosanganisira kuora kwe electrolyte uye kuzviburitsa kwebhatiri.Iyo yedivi rekuita kupisa kunogadzirwa mune iyi maitiro maQs.Pamusoro pezvo, nekuti chero bhatiri rinenge riine kuramba, Joule kupisa Qj inogadzirwa kana yazvino ichipfuura.Naizvozvo, kupisa kwese kwebhatiri ndiko kuwanda kwekupisa kwezvinhu zvinotevera: Qt=Qr+Qp+Qs+Qj.
Zvichienderana nekuchaja kwacho (kuburitsa) maitiro, zvinhu zvikuru zvinokonzeresa kuti bhatiri riite kupisa zvakasiyanawo.Semuenzaniso, kana bhatiri richiwanzochajiwa, Qr ndiyo inonyanya kukosha;uye padanho rekupedzisira rekuchaja bhatiri, nekuda kwekuparara kweelectrolyte, kuita kwedivi kunotanga kuitika (side reaction heat iQs), bhatiri parinenge rave kuzara nekuchajiswa, Chinonyanya kuitika kuparara kwe electrolyte, uko Qs inotonga. .Iyo Joule kupisa Qj kunoenderana neyazvino uye kuramba.Iyo inowanzoshandiswa yekuchaja nzira inoitwa pasi penguva dzose ikozvino, uye Qj inokosha chaiyo panguva ino.Zvisinei, panguva yekutanga-up uye kukurumidza, ikozvino inenge yakakwirira.KuHEV, izvi zvakaenzana nemakumi emakumi ema amperes kusvika kumazana ema amperes.Panguva ino, iyo Joule heat Qj yakakura kwazvo uye inova sosi huru yekuburitsa kupisa kwebhatiri.
Kubva pakuona kwekudziya kwekutonga kwekutonga, thermal management system (HVH) inogona kupatsanurwa mumhando mbiri: inoshanda uye inongoita.Kubva pakuona kwekupisa kwepakati, masisitimu ekudziya anogona kukamurwa kuita: air-yakatonhorera (PTC Air Heater), mvura-yakatonhorera (PTC Inotonhorera hita), uye chikamu-chinja chekuchengetedza kupisa.
Pakupisa kupisa neinotonhorera (PTC Inotonhorera Heater) sepakati, zvinodikanwa kumisikidza kutaurirana kwekupisa pakati pemodule uye yemvura yepakati, senge bhachi remvura, kuitisa kudziya kusinganange uye kutonhora nenzira ye convection uye kupisa. conduction.Iyo inopisa yekupisa svikiro inogona kuva mvura, ethylene glycol kana kunyange Refrigerant.Kune zvakare yakananga kupisa kupisa nekunyudza chidimbu chedanda mumvura ye dielectric, asi matanho ekudzivirira anofanirwa kutorwa kudzivirira pfupi pfupi.
Passive coolant kutonhodza kazhinji inoshandisa mvura-ambient air heat exchange uye yobva yapinza makokoni mubhatiri yekutsinhanisa kupisa kwechipiri, ukuwo kutonhora kunoshanda kunoshandisa injini inotonhorera-mvura yepakati kupisa inotsinhanisa, kana PTC yemagetsi yekudziya / kupisa mafuta ekudziya kuti iwane kutonhora kwekutanga.Kudziya, kutonhora kwekutanga nemufambi kabhini mhepo / air conditioning refrigerant-liquid medium.
Kune masisitimu ekutonga anopisa anoshandisa mhepo uye mvura sepakati, chimiro chakakura uye chakaomarara nekuda kwekudiwa kwemafeni, pombi dzemvura, zvinopisa kupisa, heaters, mapaipi nezvimwe zvinhu, uye zvakare inoshandisa simba rebhatiri uye inoderedza simba rebhatiri. .density uye simba density.
Mvura inotonhorera yebhatiri inotonhorera inoshandisa inotonhorera (50% mvura / 50% ethylene glycol) kuendesa kupisa kwebhatiri kune air-conditioning refrigerant system kuburikidza nebhatiri inotonhorera, uyezve kune zvakatipoteredza kuburikidza ne condenser.Iyo bhatiri inlet tembiricha yemvura inotonhorera nebhatiri Zviri nyore kusvika kune yakaderera tembiricha mushure mekupisa kupisa, uye bhatiri rinogona kugadziridzwa kuti rimhanye pane yakanakisa tembiricha yekushanda;iyo system musimboti inoratidzwa mumufananidzo.Izvo zvikamu zvikuru zvefiriji system zvinosanganisira: condenser, electric compressor, evaporator, valve yekuwedzera nevhavha yekuvhara, bhatiri inotonhorera (vhavha yekuwedzera nevhavha yekuvhara) uye mhepo inogadzirisa pombi, nezvimwewo;inotonhorera yemvura inotonhorera inosanganisira: yemagetsi pombi yemvura, bhatiri (kusanganisira inotonhorera mahwendefa), bhatiri inotonhorera, pombi dzemvura, matangi ekuwedzera uye zvimwe zvinhu.
