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 kwehutongi hwehutongi hwekudziya, masisitimu ekutonga anogona kukamurwa kuita marudzi maviri: anoshanda uye asingaiti.Kubva pamaonero epakati pekutamisa kupisa, masisitimu ekudziya anogona kukamurwa kuita: mhepo-yakatonhorera, mvura-yakatonhorera, uye nhanho-shanduko yekushisa kuchengetedza.
Thermal manejimendi nemhepo senge kupisa kwepakati
Iyo yekupisa yekupisa svikiro ine simba rakakura pakuita uye mutengo weiyo thermal management system.Kushandiswa kwemhepo semhepo yekufambisa kupisa ndeyekuunza zvakananga mhepo kuitira kuti inoyerera kuburikidza nebhatiri module kuti iwane chinangwa chekupisa kupisa.Kazhinji, mafeni, inlet uye outlet ventilation uye zvimwe zvikamu zvinodiwa.
Zvinoenderana neakasiyana masosi ekutorwa kwemhepo, kune kazhinji anotevera mafomu:
1 Passive kutonhora nekunze kwemhepo yekufema
2. Passive kutonhora / kudziyisa kwevafambi compartment air ventilation
3. Kushanda kutonhora / kupisa kwekunze kana kwemutakuri wemhepo
Iyo passive system dhizaini iri nyore uye inoshandisa zvakananga nharaunda iripo.Semuenzaniso, kana bhatiri richida kudziyiswa munguva yechando, nharaunda inopisa mukamuri yevafambi inogona kushandiswa kufemera mweya.Kana tembiricha yebhatiri yakakwira zvakanyanya panguva yekutyaira uye kutonhora kwemhepo mukamuri yevatakuri isina kunaka, mweya unotonhora unobva kunze unogona kufemerwa kuti utonhorere pasi.
Kune iyo inoshanda sisitimu, yakaparadzana sisitimu inoda kugadzikiswa kuti ipe kupisa kana kutonhora mabasa uye kuve yakazvimiririra kudzorwa zvinoenderana nemamiriro ebhatiri, ayo anowedzerawo kushandiswa kwesimba uye mutengo wemotokari.Kusarudzwa kwemaitiro akasiyana kunonyanya kuenderana nezvinodiwa zvekushandisa zvebhatiri.
Thermal manejimendi ine mvura senge kupisa kwepakati
Pakupisa kupisa nemvura seyepakati, zvinodikanwa kumisikidza kutaurirana kwekupisa pakati peiyo module uye yemvura yepakati, senge bhachi remvura, kuitisa kupisa kusina kunanga 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 fluid kutonhora kunowanzo shandisa mvura-ambient air heat exchange uye yobva yapinza makokoni mubhatiri yekutsinhanisa kupisa kwechipiri, uku kutonhora kunoshanda kunoshandisa injini inotonhorera-mvura yepakati kupisa inochinjanisa, kana magetsi ekudziya / kupisa mafuta ekudziya kuti awane kutonhora kwekutanga.Kudziya, kutonhora kwekutanga nemufambi kabhini mhepo / air conditioning refrigerant-liquid medium.
Iyo thermal manejimendi system ine mhepo uye mvura senge svikiro inoda mafeni, pombi dzemvura, zvinopisa zvinopisa, zvinopisa (PTC air heater), mapaipi uye zvimwe zvishongedzo kuita kuti chimiro chive chakakurisa uye chakaoma, uye zvakare chinopedza simba rebhatiri, array Kuwanda kwesimba uye kusimba kwesimba kwebhatiri kunoderedzwa.
(PTC inotonhoreraheater) Mvura inotonhorera yebhatiri inotonhorera inoshandisa inotonhorera (50% mvura / 50% ethylene glycol) kuendesa kupisa kubva mubhatiri kusvika kune air-conditioning refrigerant system kuburikidza nebheteri inotonhorera, uye zvakare kune zvakatipoteredza kuburikidza ne condenser.Iyo tembiricha yemvura inotengeswa kunze kwenyika iri nyore kusvika kune yakaderera tembiricha mushure mekutsinhana kwekupisa nebhatiri inotonhorera, uye bhatiri rinogona kugadziridzwa kuti rishande pane yakanakisa yekushanda tembiricha renji;iyo system musimboti inoratidzwa mumufananidzo.Zvikamu zvikuru zvefiriji system zvinosanganisira: condenser, electric compressor, evaporator, valve yekuwedzera nevhavha yekumisa, bhatiri inotonhorera (vhavha yekuwedzera nevhavha yekumira) uye pombi dzemhepo, nezvimwewo;kutonhora kwemvura kutenderera kunosanganisira:pombi yemvura yemagetsi, bhatiri (kusanganisira mahwendefa ekutonhodza), mabhatiri anotonhorera, pombi dzemvura, matangi ekuwedzera nezvimwe zvinhu.
