Njani malunga nokutshaja kwe-DC okanyeUkutshaja ngokukhawuleza kwe-DCkwizithuthi zombane?Kule bhlog siza kufunda ngezinto ezintathu: Okokuqala, zeziphi iindawo eziphambili zetshaja yeDC.Okwesibini, zeziphi iintlobo zeziqhagamshelo ezisetyenziselwa ukutshaja kwe-DC kwaye okwesithathu yintoni imida yokutshaja ngokukhawuleza kwe-DC.
Zeziphi iindawo eziphambili zokutshaja kwe-DC?
Okokuqala makhe sijonge ukuba zeziphi iindawo eziphambili zetshaja yeDC.Iitshaja ezikhawulezayo ze-DCngokuqhelekileyo asebenza kwinqanaba lamandla amathathu okutshaja kwaye ayilelwe ukutshaja iivektha zombane ngokukhawuleza, ngombane ophuma phakathi kwe-50 kilowatts ukuya kwi-350 kilowatts, kunye nokusebenza kwamandla aphezulu i-ac ukuya kwi-DC converter.Isiguquli se-DC ukuya kwi-DC kunye neesekethe zolawulo lwamandla ziba nkulu kwaye zibize kakhulu, yiyo loo nto itshaja ekhawulezayo ye-DC iphunyezwe njengazo zonke iitshaja ezinyanzelisiweyo endaweni yokuba itshaja ezithengiweyo.Ukuze ingathathi indawo ngaphakathi kwesithuthi kwaye itshaja ekhawulezayo inokwabelwana ngayo ngabasebenzisi abaninzi.
Ngoku makhe sihlalutye ukuhamba kwamandla e-DC ukutshaja ukusuka kwitshaja yeDC ukuya kwibhetri yemoto yombane.Kwinqanaba lokuqala, amandla akhoyo atshintshanayo okanye amandla e-ac anikezelwayo yi-ac grid aguqulwa kuqala abe ngumbane othe ngqo.Amandla eDCusebenzisa isilungisi ngaphakathi kwisikhululo sokutshaja seDC.Emva koko iyunithi yokulawula amandla ilungelelanisa ngokufanelekileyo i-voltage kunye neyangoku ye-converter ye-DC ukulawula ukuguquguquka kwamandla e-DC anikezelwe ukutshaja ibhetri.
Kukho i-interlocks yokhuseleko kunye neesekethe zokukhusela ezisetyenziselwa ukucima i-av connector kunye nokumisa inkqubo yokutshaja.Nanini na kukho imeko yempazamo okanye unxibelelwano olungafanelekanga phakathi kwe-ev kunye netshaja, inkqubo yolawulo lwebhetri okanye i-bms idlala indima ephambili yokunxibelelana phakathi kwesikhululo sokutshaja kunye nokulawula amandla ombane kunye nokuhanjiswa kwangoku kwibhetri kunye nokusebenza kwesekethe yokhuseleko imeko yemeko engakhuselekanga.Umzekelo, uthungelwano lwendawo yolawulo ngokukhawuleza lubhekisa kwisikena okanye unxibelelwano lwentambo yombane ngokukhawuleza lubhekiselele kwi-plc esetyenziselwa unxibelelwano phakathi kwe-ev kunye netshaja ngoku unombono osisiseko wendlela itshaja ye-DC eqwalaselwe ngayo.Emva koko ke makhe sijonge kwiindidi ze-DC zetshaja eziphambili kukho iindidi ezintlanu ze-DC zokutshaja iziqhagamshelo ezisetyenziswa kwihlabathi jikelele.
Loluphi uhlobo lweziqhagamshelo ezisetyenziselwa ukutshaja kwe-DC?
Okokuqala yi-ccs okanye inkqubo yokutshaja edibeneyo ebizwa ngokuba yi-combo enye isidibanisi esisetyenziswa kakhulu kwi-us.Eyesithathu sisidibanisi sedemo ye-asha esetyenziswa kwihlabathi jikelele kwiimoto ezakhiwe ngabavelisi baseJapan ubukhulu becala yesine isidibanisi se-ds tesla DC esisetyenziselwa ukutshaja ngokunjalo kwaye ekugqibeleni iChina inesinxibelelanisi se-DC esekwe kumgangatho waseTshayina we-gbt.
Ngoku makhe sijonge ezi ziqhagamshelo nganye nganye inkqubo yokutshaja edityanisiweyo okanye iziqhagamshelo ze-ccs zikwabhekiselele kuzo njenge-combo r edityanisiweyo iziqhagamshelo ezidityanisiweyo kuzo zombini i-ac kunye ne-DC yokutshaja evela kuhlobo loku-1 kunye nohlobo lwesi-2 lwezihlanganisi zokutshaja kwe-ac ngokudibanisa izikhonkwane ezibini ezongezelelweyo umzantsi wokutshaja okuphezulu kwangoku kwe-DC.Izihlanganisi ezivela kuhlobo lwe-1 kunye nohlobo lwe-2 ngokulandelelana zibizwa ngokuba yi-combo 1 kunye ne-combo 2.
Makhe siqale sijonge i-ccs combo 1 isixhumi kwesi silayidi, i-combo ye-1 imoto edibeneyo iboniswe kwicala lasekhohlo kwaye i-inlet yesithuthi iboniswe kwicala lasekunene, i-connector yemoto ye-combo 1 ithathwe kwi-ac yohlobo lwe-1 ikhonkco. kwaye igcina isikhonkwane somhlaba kunye nezikhonkwane zomqondiso ezi-2 ezizezi pilot yolawulo kunye nomqhubi wokusondela ukongeza kwizikhonkwane zamandla zeDC zongezwa ukutshaja ngokukhawuleza ezantsi kwesinxibelelanisi.
Kwi-inlet yesithuthi i-pin configuration inxalenye ephezulu ifana ne-ac yohlobo lwe-1 isidibanisi sokutshaja kwe-ac ngelixa izikhonkwane ezi-2 ezisezantsi zisetyenziselwa ukutshaja kwe-DC ngokufanayo.I-ccs combo izihlanganisi ezimbini zithathwe kuhlobo lwe-ac izihlanganisi ezimbini kwaye zigcina isikhonkwane somhlaba kunye nezikhonkwane ezimbini zesignali ezizezi umqhubi wolawulo kumqhubi okufutshane ukuya kwi-DC izikhonkwane zamandla zongezwa ezantsi kwesidibanisi sokutshaja okuphezulu kwamandla eDC ngokufanayo. .
Kwisithuthi kwelo cala inxalenye ephezulu iququzelela ukutshaja kwe-ac ukusuka kwisigaba sesithathu kunye nakwindawo esezantsi.Unayo i-DC yokutshaja ngokungafaniyo nohlobo loku-1 kunye nohlobo lwe-2 izihlanganisi ezisebenzisa kuphela ukumodareyitha kobubanzi be-pulse okanye isignali ye-pwm kumqhubi wolawulo unxibelelwano lwentambo yombane ye-plc isetyenziswa zombini kwi-combo 1 kunye ne-combo 2 iitshaja kwaye oku kuveliswa kulawulo. .
Unxibelelwano lweentambo zamandla okulingayo bubuchwephesha obuthwala idatha yonxibelelwano kwiintambo zamandla ezikhoyo ezisetyenziselwa ugqithiselo ngaxeshanye zombini umqondiso kunye nokuhanjiswa kwamandla ii-ccs combo tshaja zinokuhambisa ukuya kuma-350 amps kumbane ophakathi kwe-200 ukuya kwi-1000 volts.Ukunika amandla aphezulu emveliso ye-350 kilowatts kufuneka kukhunjulwe ukuba la maxabiso ahlaziywa ngokuqhubekayo ngemigangatho yokutshaja ukulungiselela iimfuno zombane kunye namandla eemoto zombane ezintsha.Uhlobo lwesithathu lwetshaja ye-DC sisidibanisi sesithunzi esiluhlobo lwe-4 eb isidibanisi esinezikhonkwane zamandla ezintathu kunye nezikhonkwane zomqondiso ezintandathu kulo msebenzi.I- shidae moe isebenzisa inethiwekhi yendawo yolawulo okanye i-protocol ye-kin kwiiphini zonxibelelwano zonxibelelwano.
Phakathi kwetshaja kunye nemoto indawo yokulawula unxibelelwano lwenethiwekhi ngumgangatho wonxibelelwano wesithuthi oqinileyo uthatha isigqibo sokuvumela i-microcontrollers kunye nezixhobo ukuba zinxibelelane ngexesha langempela.Ngaphandle komkhosi wekhompyutha njengangoku umbane kunye namanqanaba angoku kunye namandla e-shada moe asuka kwi-50 ukuya kwi-400 volts kunye ne-current ukuya kuma-amps angama-400 ngaloo ndlela enikezela, amandla aphezulu ukuya kuma-kilowatts angama-200 ukutshaja kwixesha elizayo.
Kulindeleke ukuba i-eb ibize ukuya kuthi ga kwi-1,000 volts kunye ne-400 kilowatts iya kuququzelelwa yidemo ngoku.Masiqhubele phambili kwiziqhagamshelo zeshaja ye-tesla, inethiwekhi ye-tesla supercharger e-United States isebenzisa isiqhagamshelo setshaja efanelekileyo ngelixa i-european eyahlukileyo isebenzisa uhlobo lwesi-2 isinxibelelanisi se-minoccurs kodwa nge-DC yokutshaja eyakhelwe-kwinkalo eyodwa ye-tesla isinxibelelanisi sinjengesiqhagamshelanisi esifanayo. ingasetyenziselwa ukutshaja kwe-ac kunye ne-DC yokutshaja i-tesla ngoku.Inikezela nge-DC ukutshaja ukuya kuthi ga kwi-120 kilowatts kwaye oku kulindeleke ukuba kunyuke kwixesha elizayo.
Yeyiphi imida yokuTshaja ngokukhawuleza kwe-DC?
Okokugqibela, iChina inomgangatho omtsha wokutshaja weDC kunye nesinxibelelanisi esisebenzisa inethiwekhi yendawo yokulawula ibhasi.Ibhasi ingene kunxibelelwano inezikhonkwane zamandla ezintlanu ezimbini kumandla eDC kwaye ezimbini zokuhanjiswa kombane oncedisayo ophantsi-voltage kunye neyomhlaba kwaye inezikhonkwane ezine zomqondiso ezimbini zomqhubi wokusondela kwaye ezimbini zonxibelelwano lwenethiwekhi yendawo yolawulo.Ukuza kuthi ga ngoku i-voltage yegama elisetyenzisiweyo kwesi sidibanisi okanye i-750 volts okanye i-1000 volts kwaye okwangoku ukuya kuma-amps angama-250 ixhaswa yile tshaja.Iyakwazi ukubona ukutshaja okukhawulezayo kunomtsalane ngenxa yamandla aphezulu okutshaja ukuya kuthi ga kuma-300 okanye ama-400 ekilowatts.
Oku kukhokelela kumaxesha amafutshane kakhulu wokutshaja kodwa amandla okutshaja ngokukhawuleza awanakunyuswa ngokungenasiphelo, oku kungenxa yemida emithathu yobugcisa yokutshaja ngokukhawuleza.Ngoku makhe sijonge ezi zithintelo kuqala kuyo yonke into ephezulu yokutshaja ngoku kukhokelela kwilahleko ephezulu iyonke kwitshaja nakwibhetri.
Umzekelo, ukuba ukuchasana kwangaphakathi kwebhetri ngu-r kwaye ilahleko kwibhetri ingabonakaliswa ngokulula usebenzisa i-formula i-squared r apho ndingumbane wokutshaja ngoko uya kuqaphela ukuba ilahleko yanda ngokuphindwe kane.Nanini na, umsinga uphinda-phinda okwesibini umda wesibini uvela kwibhetri xa uqala ukutshaja ibhetri.Imeko yokutshaja kwebhetri inokuba kukunyuka ukuya kwimo yentlawulo yama-70 ukuya kuma-80% oku kungenxa yokuba ukutshaja ngokukhawuleza kudala ukushiyeka phakathi kombane kunye nemeko yentlawulo.
Le nto iyanda kwibhetri itshajiswa ngokukhawuleza kungoko.Ukutshaja okokuqala kwenziwa kwindawo engaguqukiyo yangoku okanye ye-cc yokutshaja kwebhetri kwaye emva koko.Amandla okutshaja acuthwa kancinci kancinci kwindawo yokutshaja okungaguqukiyo okanye kwingingqi yokutshaja i-cv ngaphezu koko izinga lokutshaja kweebhetri okanye isantya sokutshaja siyenyuka ngokutshaja ngokukhawuleza kwaye oku kukhokelela ekuncipheni kwexesha lokuphila kwebhetri.
Umda wesithathu uvela kwintambo yokutshaja kuyo nayiphi na itshaja ye-evie kubalulekile ukuba intambo ibe bhetyebhetye kwaye ilula.Ke abantu banokuthwala intambo kwaye bayidibanise nemoto enamandla amakhulu okutshaja iintambo ezityebileyo nezityebileyo ziyafuneka ukuvumela umsinga wokutshaja ongakumbi, kungenjalo uya kufudumala.Ngenxa yelahleko, iinkqubo zokutshaja ngokukhawuleza kwe-DC namhlanje ziyakwazi ukuthumela imisinga yokutshaja ukuya kuthi ga kwi-250 amperes ngaphandle kokupholisa.
Nangona kunjalo, kwixesha elizayo ngemisinga malunga ne-250 amp ere iintambo zokutshaja ziya kuba nzima kakhulu kwaye zingabi bhetyebhetye ukuba zisetyenziswe.Isisombululo siya kuba kukusebenzisa iintambo ezicekethekileyo zangoku ezinikiweyo ezineenkqubo zokupholisa ezakhelwe ngaphakathi kunye nolawulo lwe-thermal ukuqinisekisa ukuba iintambo azitshisi.Kakade ke, intsonkothe ngakumbi kwaye ibiza kakhulu kunokusebenzisa intambo ngaphandle kokupholisa, ngoko ke ukusonga le bhlog kule blog sabona iindawo eziphambili ze-DC okanye itshaja ethe ngqo ngoku ngakumbi sajonga kwiindidi ezahlukeneyo ze-DC connector.
