Sesimba guru remagetsi emagetsi matsva, mabhatiri emagetsi akakosha zvikuru kumotokari dzemagetsi matsva.Munguva yekushandiswa chaiko kwemotokari, bhatiri ichatarisana nemamiriro ezvinhu akaoma uye anoshanduka ekushanda.Kuti uvandudze huwandu hwekufamba, mota inoda kuronga mabhatiri akawanda sezvinobvira mune imwe nzvimbo, saka nzvimbo yebhatiri pack pamotokari ishoma.Bhatiri inogadzira kupisa kwakawanda panguva yekushanda kwemotokari uye inoungana munzvimbo diki nekufamba kwenguva.Nekuda kwekuremerwa kwemaseru mubhatiri pack, zvakatonyanya kuoma kudzima kupisa munzvimbo yepakati kusvika padanho rakati, zvichiwedzera kusawirirana kwekushisa pakati pemaseru, izvo zvinoderedza kuchaja uye kuburitsa kushanda kwebhatiri uye. kukanganisa simba rebhatiri;Izvo zvinokonzeresa kutiza kwekupisa uye kukanganisa kuchengetedzwa uye hupenyu hwehurongwa.
Kupisa kwebhatiri remagetsi kune simba guru pakuita kwayo, hupenyu uye kuchengeteka.Pakupisa kwakadzika, kupikisa kwemukati kwe lithium-ion mabhatiri kuchawedzera uye simba richaderera.Muzviitiko zvakanyanyisa, electrolyte inotonhora uye bhatiri haigoni kubudiswa.Iko kuderera-kupisa kwekushanda kwebhatiri system kuchakanganiswa zvikuru, zvichiita kuti simba rekubuda kwemagetsi emotokari yemagetsi.Kupera uye kuderedza huwandu.Paunenge uchichaja mota dzemagetsi matsva pasi pemamiriro ekushisa akadzikama, iyo BMS inotanga kupisa bhatiri kune tembiricha yakakodzera isati yachaja.Kana isina kubatwa nemazvo, inotungamira kune instantaneous voltage overcharge, zvichikonzera mukati mepfupi wedunhu, uye humwe hutsi, moto kana kunyange kuputika kunogona kuitika.Iyo yakaderera-tembiricha yekuchaja chengetedzo dambudziko remagetsi bhatiri system inorambidza kusimudzirwa kwemotokari dzemagetsi munzvimbo dzinotonhora kusvika pamwero mukuru.
Battery thermal management nderimwe remabasa akakosha muBMS, kunyanya kuchengetedza bhatiri paki ichishanda munzvimbo yakakodzera tembiricha nguva dzese, kuitira kuchengetedza yakanakisa kushanda mamiriro ebhatiri pack.Iyo thermal manejimendi yebhatiri inonyanya kusanganisira mabasa ekutonhora, kupisa uye kuenzana kwekushisa.Kutonhodza uye kudziyisa mabasa anonyanya kugadziridzwa kuitira zvinogona kuitika zvekunze ambient tembiricha pabhatiri.Tembiricha yakaenzana inoshandiswa kuderedza mutsauko wekushisa mukati mebhatiri pack uye kudzivirira kuora nekukurumidza kunokonzerwa nekupisa kwechimwe chikamu chebhatiri.
Kazhinji kutaura, nzira dzekutonhodza dzemabhatiri emagetsi dzakakamurwa kuita zvikamu zvitatu: kutonhora kwemhepo, kutonhora kwemvura uye kutonhora kwakananga.Mhepo-yekutonhodza modhi inoshandisa mhepo yakasikwa kana mhepo inotonhodza iri mukamuri yevafambi kuti iyerere nepamusoro pebhatiri kuti iwane kuchinjana kwekupisa uye kutonhora.Kutonhodza kwemvura kunowanzo shandisa pombi inotonhorera yakazvimirira kupisa kana kutonhodza bhatiri remagetsi.Parizvino, nzira iyi ndiyo inonyanya kutonhora.Semuenzaniso, Tesla neVolt vese vanoshandisa nzira yekutonhora iyi.Iyo yakananga kutonhora sisitimu inobvisa kutonhora kwepombi yebhatiri remagetsi uye yakananga inoshandisa refrigerant kutonhodza bhatiri remagetsi.
1. Air cooling system:
Mumabhatiri emagetsi ekutanga, nekuda kwehudiki hwavo uye huwandu hwesimba, mabhatiri emagetsi mazhinji akatonhodzwa nekutonhodzwa kwemhepo.Kutonhorera kwemhepo (PTC Air Heater) yakakamurwa kuita zvikamu zviviri: kutonhora kwemhepo yepanyama uye kutonhora kwemhepo (uchishandisa feni), uye inoshandisa mhepo yakasikwa kana mhepo inotonhora mucab kutonhodza bhatiri.
Vamiririri vamiririri vemhepo-yakatonhorera masisitimu ndiNissan Leaf, Kia Soul EV, nezvimwewo;parizvino, mabhatiri e48V e48V micro-hybrid mota anowanzo kurongerwa mukamuri yevafambi, uye anotonhodzwa nekutonhodzwa kwemhepo.Chimiro chemhepo inotonhorera system iri nyore, tekinoroji yakakura, uye mutengo wakaderera.Zvisinei, nekuda kwekupisa kushoma kunotorwa nemhepo, kushanda kwayo kwekuchinja kwekushisa kwakaderera, kuenzana kwekushisa kwemukati kwebheteri hakuna kunaka, uye zvakaoma kuwana kudzora kwakanyatsojeka kwekushisa kwebheteri.Naizvozvo, iyo air-kutonhora sisitimu inowanzoenderana nemamiriro ane pfupi rwendo rwekufamba uye huremu hwemotokari.
Zvakakodzera kutaura kuti kune mhepo inotonhorera system, dhizaini yemhepo duct inoita basa rakakosha mukutonhodza maitiro.Mhepo ducts inonyanya kukamurwa kuita serial air ducts uye parallel air ducts.Iyo serial chimiro chiri nyore, asi kupikisa kwakakura;iyo parallel chimiro chakanyanya kuoma uye chinotora nzvimbo yakawanda, asi kupisa kwekupisa kufanana kwakanaka.
2. Liquid cooling system
Liquid-cooled mode zvinoreva kuti bhatiri rinoshandisa mvura inotonhorera kuchinjanisa kupisa (PTC Inotonhorera Heater)Inotonhorera inogona kupatsanurwa mumhando mbiri dzinogona kubata zvakananga bhatiri sero (silicon mafuta, castor mafuta, nezvimwewo) uye kubata bhatiri sero (mvura uye ethylene glycol, nezvimwewo) kuburikidza nemvura migero;panguva ino, mhinduro yakasanganiswa yemvura uye ethylene glycol inoshandiswa zvakanyanya.Iyo yekutonhodza yemvura inowanzowedzera chiller kune vaviri nefiriji kutenderera, uye kupisa kwebhatiri kunobviswa kuburikidza nefiriji;zvikamu zvaro zvakakosha ndeye compressor, chiller uyepombi yemvura yemagetsi.Sesimba sosi yefiriji, iyo compressor inosarudza huwandu hwekutsinhana kwekupisa kwehurongwa hwese.Iyo chiller inoshanda sekuchinjana pakati pefiriji uye mvura inotonhorera, uye huwandu hwekutsinhana kwekupisa hunosarudza zvakananga tembiricha yemvura inotonhorera.Pombi yemvura inotara mwero wekuyerera kwechitonhodza mupombi.Iyo inokurumidza kuyerera mwero, zviri nani kuita kupisa kwekushisa, uye zvinopesana.
