Sesimba guru remagetsi emagetsi matsva, mabhatiri emagetsi akakosha zvikuru kumotokari dzemagetsi matsva.Munguva yekushandiswa chaiko kwemotokari, bhatiri ichatarisana nemamiriro ezvinhu akaoma uye anoshanduka ekushanda.
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.
Pakupisa kwepamusoro, kana charger ikatadza, inogona kukonzera kemikari ine chisimba mukati mebhatiri uye kuburitsa kupisa kwakawanda.Kana kupisa kunowedzera nokukurumidza mukati mebheteri pasina nguva yekuparara, bhatiri rinogona kubuda, kubuda, kusvuta, nezvimwewo. Muzviitiko zvakakomba, bhatiri rinopisa nechisimba uye rinoputika.
Iyo bhatiri yemafuta ekutonga system (Battery Thermal Management System, BTMS) ndiro basa guru rebhatiri manejimendi system.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.Iyo yakavharwa-loop regulation system inoumbwa nekupisa-kuitisa svikiro, kuyerwa uye control unit, uye tembiricha yekudzora tembiricha, kuitira kuti bhatiri remagetsi rishande mukati meyakakodzera tembiricha renji kuchengetedza mamiriro ayo ekushandisa uye kuve nechokwadi chekuita uye hupenyu hweiyo. bhatiri system.
1. "V" modhi yekuvandudza maitiro eiyo thermal management system
Sechikamu chesimba rebhatiri system, iyo thermal manejimendi system inogadzirwa zvakare zvinoenderana neV "modhi yekuvandudza modhi yeindasitiri yemotokari. Nerubatsiro rwematurusi ekuenzanisa uye nhamba huru yekuongororwa kwebvunzo, nenzira iyi chete inogona budiriro yebudiriro inovandudzwa, mutengo wekuvandudza uye garandi system chengetedzwa.Kuvimbika, chengetedzo uye hupenyu hurefu.
Inotevera ndiyo "V" modhi ye thermal management system development.Kazhinji kutaura, modhi yacho ine matemo maviri, imwe yakachinjika uye imwe yakatwasuka: yakatwasuka axis inoumbwa nemitsetse mina mikuru yebudiriro yemberi uye mutsetse mumwe mukuru wekudzosera kumashure, uye mutsara mukuru kusimudzira mberi., tichifunga nezve reverse yakavharwa-loop verification;iyo vertical axis ine mazinga matatu: zvikamu, subsystems uye masisitimu.
Kupisa kwebhatiri kunobata zvakananga kuchengetedzeka kwebhatiri, saka dhizaini uye kutsvagisa kweiyo thermal management system yebhatiri nderimwe remabasa akanyanya kukosha mukugadzirwa kwebhatiri system.Iyo yekupisa manejimendi dhizaini uye kuoneswa kwebhatiri system inofanirwa kuitwa zvakanyatsoenderana neiyo bhatiri yekupisa manejimendi dhizaini dhizaini, bhatiri thermal manejimendi system uye echikamu mhando, yekupisa yekutonga system chikamu chechikamu, uye yekupisa manejimendi maitiro ekuongorora.Kuti uve nechokwadi chekuita uye kuchengetedzwa kwebhatiri.
1. Zvinodiwa zve thermal management system.Zvinoenderana neiyo dhizaini yekuisa paramita senge nharaunda yekushandisa yemotokari, mamiriro ekushanda emotokari, uye tembiricha hwindo rebhatiri cell, ita ongororo yekuda kujekesa zvinodiwa nebhatiri system yeiyo thermal management system;system zvinodiwa, zvinoenderana neZvinodiwa ongororo inosarudza mabasa eiyo thermal manejimendi system uye zvinangwa zvekugadzira zvehurongwa.Izvi zvibodzwa zvekugadzira zvinonyanya zvinosanganisira kutonga kwebhatiri sero tembiricha, mutsauko wetembiricha pakati pemasero ebhatiri, mashandisiro esimba rehurongwa uye mutengo.
2. Thermal management system framework.Zvinoenderana nezvinodiwa nehurongwa, sisitimu yakakamurwa kuita yekutonhora subsystem, yekudziya subsystem, thermal insulation subsystem uye thermal runaway obstructin (TRo) subsystem, uye zvinodiwa zvekugadzira zvega yega subsystem zvinotsanangurwa.Panguva imwecheteyo Simulation ongororo inoitwa kuti itange kuona dhizaini yehurongwa.Zvakaita sePTC inotonhorera heater, PTC air heater, pombi yemvura yemagetsi, nezvimwewo.
3. Subsystem dhizaini, tanga waona chinangwa chekugadzira chega yega subsystem maererano nehurongwa hwekugadzira, uye wozoita sarudzo yenzira, dhizaini dhizaini, dhizaini yakadzama uye ongororo yekunyepedzera uye kuongororwa kune imwe neimwe subsystem.
4. Zvikamu dhizaini, tanga waona zvinangwa zvekugadzira zvezvikamu zvinoenderana neiyo subsystem dhizaini, uye wozoita yakadzama dhizaini uye yekunyepedzera kuongorora.
5. Kugadzira uye kuyedzwa kwezvikamu, kugadzirwa kwezvikamu, uye kuyedzwa nekuongororwa.
6. Kubatanidzwa kweSystem uye kuongororwa, yekubatanidza subsystem uye kuongororwa kwebvunzo.
7. Kubatanidzwa kweSystem uye kuyedzwa, kubatanidzwa kwehurongwa uye kuongororwa kwekuongorora.
