Itshaja yemoto (OBC)
Itshaja esebhodini inoxanduva lokuguqula umsinga otshintshayo ukuya ngqo ngoku ukutshaja ibhetri yamandla.
Okwangoku, iimoto zombane ezinesantya esiphantsi kunye ne-A00 mini izithuthi zombane zixhotyiswe ubukhulu becala ngeetshaja ze-1.5kW kunye ne-2kW, kwaye iimoto ezingaphezulu kwe-A00 zabakhweli zixhotyiswe nge-3.3kW kunye ne-6.6kW.
Uninzi lwe-AC yokutshaja kwezithuthi zorhwebo isebenzisa 380Visigaba sesithathu sombane wemizi-mveliso, kwaye amandla angaphezulu kwe-10kW.
Ngokutsho kwedatha yophando ye-Gaogong Electric Vehicle Research Institute (GGII), kwi-2018, imfuno yemoto entsha yamandla ebhodini e-China yafikelela kwiisethi ze-1.220,700, kunye nezinga lokukhula konyaka-ngonyaka we-50.46%.
Ngokwembono yokwakheka kwemarike, iitshaja ezinamandla emveliso angaphezu kwe-5kW zithatha isabelo esikhulu semarike, malunga nama-70%.
Awona mashishini aphambili angaphandle avelisa itshaja yemoto yiKesida,Emerson, Valeo, Infineon, Bosch kunye namanye amashishini njalo njalo.
I-OBC eqhelekileyo iqulunqwe ubukhulu becala isekethe yamandla (amacandelo angundoqo aquka i-PFC kunye ne-DC/DC) kunye nesiphaluka solawulo (njengoko kubonisiwe ngezantsi).
Phakathi kwabo, umsebenzi oyintloko wesiphaluka samandla kukuguqula i-alternating current kwi-stable current ngqo; Umjikelo wolawulo ikakhulu ukuphumeza unxibelelwano kunye nebhetri, kwaye ngokwemfuno yokulawula imveliso yesekethe yamandla ombane ethile kunye neyangoku.
I-Diodes kunye neebhubhu zokutshintsha (i-IGBTs, i-MOSFETs, njl.) zixhobo eziphambili ze-semiconductor zamandla ezisetyenziswa kwi-OBC.
Ngokusetyenziswa kwezixhobo zamandla e-silicon carbide, ukusebenza kakuhle kokuguqulwa kwe-OBC kunokufikelela kwi-96%, kwaye ubuninzi bamandla bunokufikelela kwi-1.2W / cc.
Ukusebenza kakuhle kulindeleke ukuba kunyuke ngakumbi ukuya kuma-98% kwixesha elizayo.
I-topology eqhelekileyo yetshaja yemoto:
Ulawulo lobushushu bomoya womoya
Kwinkqubo yefriji ye-air conditioning yemoto yombane, ngenxa yokuba akukho injini, i-compressor kufuneka iqhutywe ngumbane, kwaye i-compressor scroll electric compressor edityaniswe ne-drive motor kunye nomlawuli isetyenziswa ngokubanzi ngoku, enomthamo ophezulu kunye nomgangatho ophantsi. iindleko.
Ukunyusa uxinzelelo lolona lwalathiso luphambili lophuhliso lweskrola compressors kwilixa elizayo.
Isifudumezi somoya kwinqwelo yombane sikufanele ukuqwalaselwa ngakumbi.
Ngenxa yokunqongophala kwe-injini njengomthombo wobushushu, izithuthi zombane zihlala zisebenzisa i-PTC thermistors ukufudumeza i-cockpit.
Nangona esi sisombululo sikhawuleza kwaye sizenzekelayo ubushushu obuqhelekileyo, iteknoloji ikhulile ngakumbi, kodwa i-disadvantage kukuba ukusetyenziswa kwamandla kukhulu, ngakumbi kwindawo ebandayo xa ukufudumala kwe-PTC kunokubangela ngaphezu kwe-25% yokunyamezela kwezithuthi zombane.
Ke ngoko, itekhnoloji yempompo yokufudumeza umoya yomoya ithe ngokuthe ngcembe yaba sisisombululo esisesinye, esinokugcina malunga ne-50% yamandla kuneskimu sokufudumeza se-PTC kubushushu obumalunga ne-0 ° C.
Ngokubhekiselele kwiifriji, i-European Union's "Automotive Air Conditioning System Directive" ikhuthaze ukuphuhliswa kweefriji ezintsha zeinto yokufaka umoya endlini, kunye nokusetyenziswa kwefriji ye-CO2 (R744) ehambelana nokusingqongileyo kunye ne-GWP 0 kunye ne-ODP 1 iye yanda ngokuthe ngcembe.
Xa kuthelekiswa ne-HFO-1234yf, i-HFC-134a kunye nezinye izikhenkcezisi kuphela kwi--5 degrees ngasentla zinesiphumo esihle sokupholisa, i-CO2 ku- -20 ℃ umlinganiselo wokufudumeza amandla okufudumeza usenokufikelela kwi-2, likamva lemoto yombane yempompo yobushushu bomoya osebenza kakuhle. lolona khetho lungcono.
Itheyibhile : Indlela yophuhliso lwemathiriyeli yefriji
Ngophuhliso lwezithuthi zombane kunye nokuphuculwa kwexabiso lenkqubo yokulawula i-thermal, indawo yemarike yolawulo lombane lolawulo lombane lubanzi.
