Imwe yematekinoroji akakosha emotokari itsva dzinoshandisa simba mabhatiri emagetsi. Hunhu hwemabhatiri hunosarudza mutengo wemotokari dzemagetsi kune rumwe rutivi, uye huwandu hwemotokari dzemagetsi kune rumwe rutivi. Chinhu chikuru chekugamuchirwa uye kushandiswa nekukurumidza.
Zvichienderana nehunhu hwemashandisirwo, zvinodiwa uye nzvimbo dzekushandiswa kwemabhatiri emagetsi, mhando dzekutsvaga nekugadzira mabhatiri emagetsi munyika nekune dzimwe nyika ndedzinotevera: mabhatiri e lead-acid, mabhatiri e nickel-cadmium, mabhatiri e nickel-metal hydride, mabhatiri e lithium-ion, masero emafuta, nezvimwewo, pakati pazvo kugadzirwa kwemabhatiri e lithium-ion kunonyanya kutariswa.
Maitiro ekugadzira kupisa kwebhatiri remagetsi
Kunobva kupisa, mwero wekugadzira kupisa, kugona kupisa kwebhatiri nezvimwe zvinoenderana nemodule yebhatiri remagetsi zvine hukama hwakanyanya nehunhu hwebhatiri. Kupisa kunoburitswa nebhatiri kunoenderana nehunhu hwemakemikari, mechanical uye emagetsi uye hunhu hwebhatiri, kunyanya hunhu hwe electrochemical reaction. Simba rekupisa rinogadzirwa mukuita kwebhatiri rinogona kuratidzwa nekupisa kwebhatiri Qr; electrochemical polarization inoita kuti voltage chaiyo yebhatiri isiyane ne equilibrium electromotive force yayo, uye kurasikirwa kwesimba kunokonzerwa nekupisa kwebhatiri kunoratidzwa neQp. Pamusoro pekuita kwebhatiri kuenderera mberi zvichienderana ne reaction equation, kunewo mamwe maitiro emativi. Maitiro akajairika emativi anosanganisira kuora kwe electrolyte uye kuzviburitsa kwebhatiri. Kupisa kwe reaction yemativi kunogadzirwa mukuita uku ndiQs. Pamusoro pezvo, nekuti chero bhatiri richava ne resistance, Joule heat Qj inogadzirwa kana magetsi apfuura. Naizvozvo, kupisa kwese kwebhatiri ndiko huwandu hwekupisa kwezvinhu zvinotevera: Qt=Qr+Qp+Qs+Qj.
Zvichienderana nemaitiro chaiwo ekuchaja (kuburitsa), zvinhu zvikuru zvinokonzera kuti bhatiri ribudise kupisa zvakasiyanawo. Semuenzaniso, kana bhatiri richichaja kazhinji, Qr ndiyo inonyanya kukosha; uye padanho rekupedzisira rekuchaja bhatiri, nekuda kwekuora kwe electrolyte, maitiro eparutivi anotanga kuitika (kupisa kweparutivi ndiQs), kana bhatiri rava kuda kuchaja zvakazara uye rakawandisa, Chinonyanya kuitika kuora kwe electrolyte, uko Qs inotonga. Joule heat Qj inoenderana ne current uye resistance. Nzira inowanzoshandiswa yekuchaja inoitwa pasi pe constant current, uye Qj inhamba chaiyo panguva ino. Zvisinei, panguva yekutanga nekukurumidzisa, current inenge yakakwira. Kune HEV, izvi zvakaenzana ne current yemakumi ema amperes kusvika mazana ema amperes. Panguva ino, Joule heat Qj yakakura kwazvo uye inova sosi huru yekuburitsa kupisa kwebhatiri.
Kubva pamaonero ekugona kudzora mashandiro ekupisa, masisitimu ekugadzirisa mashandiro ekupisa (HVH) inogona kukamurwa kuita mhando mbiri: inoshanda uye isingashande. Kubva pamaonero enzvimbo yekufambisa kupisa, masisitimu ekutonga kupisa anogona kukamurwa kuita: inotonhodzwa nemhepo (PTC Air Heater), yakatonhorerwa nemvura (PTC Inotonhorera hita), uye nzvimbo yekuchengetedza kupisa inochinja-chinja chikamu.
Kuti upinze kupisa uchishandisa chinhu chinotonhodza (PTC Coolant Heater) senzvimbo yekupisa, zvakakosha kuti pave nekutaurirana pakati pemodule nechinhu chinotonhodza, senge jaketi remvura, kuti upinze kupisa nekutonhodza zvisina kunanga nenzira ye convection uye heat conduction. Chinhu chinotonhodza kupisa chinogona kuva mvura, ethylene glycol kana kunyange Refrigerant. Kunewo kutamiswa kwekupisa zvakananga nekunyudza danda mumvura ye dielectric, asi matanho ekudzivirira anofanira kutorwa kudzivirira short circuit.
Kutonhodza kusingapindi mvura kunowanzo shandisa kuchinjana kwemhepo inodziya munzvimbo ine mvura uye kunobva kwaisa macocoons mubhatiri kuti vagochinjana kupisa kwechipiri, ukuwo kutonhodza kuchishandisa zvinochinjana kupisa zveinjini zvinodziya-mvura, kana kuti PTC electric heating/thermal oil heating kuti zvitonhodze. Kupisa, kutonhodza kwekutanga nemhepo/mhepo inotonhodza refrigerant-liquid medium.
Kune masisitimu ekuchengetedza kupisa anoshandisa mhepo nemvura senzvimbo, chimiro chacho chakakura uye chakaoma nekuda kwekudiwa kwemafeni, mapombi emvura, ma heat exchangers, ma heaters, mapaipi nezvimwe zvinoshandiswa, uye zvinoshandisawo simba rebhatiri uye zvinoderedza simba rebhatiri.
Sisitimu yekutonhodza bhatiri inotonhodzwa nemvura inoshandisa chinotonhodza (50% mvura / 50% ethylene glycol) kuendesa kupisa kwebhatiri kune sisitimu yekutonhodza mhepo kuburikidza nechitonhodza bhatiri, uye wobva waenda kunzvimbo iri kuburikidza nechitonhodza. Tembiricha yemvura inopinzwa nebhatiri inotonhodzwa. Zviri nyore kusvika patembiricha yakaderera mushure mekutsinhana kwekupisa, uye bhatiri rinogona kugadziriswa kuti rishande patembiricha yepamusoro yekushanda; musimboti wesisitimu unoratidzwa mumufananidzo. Zvikamu zvikuru zvesisitimu yekutonhodza zvinosanganisira: condenser, electric compressor, evaporator, expansion valve ine shut-off valve, battery cooler (expansion valve ine shut-off valve) uye air conditioning pombi, nezvimwewo; circuit yemvura inotonhodza inosanganisira: electric water pombi, battery (kusanganisira ma cooling plates), battery coolers, water pombi, expansion tanks nezvimwe zvinhu.
