Kwiminyaka yakutshanje, iimoto zombane (EVs) ziye zanda kakhulu njengezinye iindlela ezihambelana nokusingqongileyo kwiimoto zepetroli zesintu. Ngenxa yoko, imfuno yezikhululo zokutshaja iimoto zombane nayo inyuke kakhulu. Ezi zikhululo zokutshaja zidlala indima ebalulekileyo ekwamkelweni okubanzi kwezithuthi zombane njengoko zibonelela abanini ngendlela efanelekileyo nekhawulezayo yokubiza izithuthi zabo. Kodwa uyenza njani iprototype yebhodi yesekethe eprintiweyo (PCB) kwezi zikhululo zokutshaja?Kule post yebhlog, siza kuphonononga esi sihloko ngokweenkcukacha kwaye sixoxe ngokunokwenzeka kunye neenzuzo zeprototyping PCBs kwizikhululo zokutshaja iimoto zombane.
Ukuchwetheza nge-PCB kuso nasiphi na isicelo kufuna ucwangciso olululo, uyilo, kunye novavanyo.Nangona kunjalo, kwizikhululo zokutshaja iimoto zombane, imingcipheko inkulu ngakumbi. Ezi zikhululo zokutshaja kufuneka zithembeke, zisebenze kwaye zikwazi ukuphatha ukutshaja kwamandla aphezulu. Ke ngoko, ukuyila iPCB yale nkqubo intsonkothileyo kufuna ubuchule kunye nokuqonda iimfuno ezithile zokutshaja kwe-EV.
Inyathelo lokuqala kwi-prototyping yesikhululo sokutshaja isithuthi sombane iPCB kukuqonda iimfuno zokusebenza kwesistim.Oku kuquka ukumisela iimfuno zamandla, iimpawu zokhuseleko, iiprothokholi zonxibelelwano kunye nazo naziphi na ezinye iingqalelo ezikhethekileyo. Nje ukuba ezi mfuno zimiselwe, inyathelo elilandelayo kukuyila iisekethe kunye namacandelo ahlangabezana nezi mfuno.
Inkalo ephambili yokuyila i-PCB yesikhululo sokutshaja i-EV yinkqubo yolawulo lwamandla.Inkqubo inoxanduva lokuguqula igalelo lamandla e-AC ukusuka kwigridi ukuya kumandla afanelekileyo eDC afunekayo ukutshaja iibhetri ze-EV. Ikwajongana neempawu ezahlukeneyo zokhuseleko ezinje ngokhuseleko lwe-overcurrent, ukhuseleko lwesekethe emfutshane, kunye nolawulo lombane. Ukuyila le nkqubo kufuna ingqalelo ngononophelo ukhetho lwamacandelo, ulawulo lwe-thermal, kunye ne-circuit layout.
Enye into ebalulekileyo ekufuneka iqwalaselwe xa uyila iprototype yePCB yesikhululo sokutshaja isithuthi sombane lujongano lonxibelelwano.Izikhululo zokutshaja iimoto zombane zidla ngokuxhasa iinkqubo ezahlukeneyo zonxibelelwano ezifana ne-Ethernet, iWi-Fi okanye uqhagamshelo lweselula. Ezi prothokholi zivumela ukubekwa esweni okude, ukuqinisekiswa komsebenzisi, kunye nokulungiswa kwentlawulo. Ukuphumeza olu jongano lonxibelelwano kwi-PCB kufuna uyilo olunenkathalo kunye nokudityaniswa nenkqubo yolawulo lwamandla.
Kwizikhululo zokutshaja iimoto zombane, ukhuseleko yeyona nto ixhalabisayo.Ngoko ke, uyilo lwePCB kufuneka lubandakanye iimpawu eziqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo. Oku kubandakanya ukukhuselwa kombane, ukubeka iliso kwiqondo lokushisa kunye nokuziva ngoku. Ukongeza, iiPCBs kufuneka ziyilelwe ukumelana nezinto zokusingqongileyo ezinje ngokufuma, ubushushu, kunye nokungcangcazela.
Ngoku, makhe sixoxe ngoncedo lokuchwetheza kwi-PCB yesikhululo sokutshaja isithuthi sombane.Ngokuchwetheza ii-PCBs, iinjineli zinokuchonga iziphene zoyilo kwaye zenze uphuculo phambi kokuveliswa kobuninzi. Ivavanya kwaye ingqinisise isekethe yesikhululo sokutshaja, ukusebenza kunye nokusebenza. Iprototyping inokuvavanya amacandelo ahlukeneyo kunye nobuchwepheshe bokuqinisekisa ukuba uyilo lokugqibela luhlangabezana neenkcukacha ezifunekayo.
Ukongeza, ii-PCB zeprototyping kwizikhululo zokutshaja izithuthi zombane zivumela ukwenziwa ngokwezifiso kunye nokulungelelanisa kwiimfuno ezithile.Njengoko iteknoloji yemoto yombane iguquka, izikhululo zokutshaja zisenokufuna ukuhlaziywa okanye ukufakwa ngokutsha. Ngoyilo lwePCB oluguquguqukayo noluguquguqukayo, olu tshintsho lunokudityaniswa ngokulula ngaphandle kwemfuneko yoyilo ngokutsha olupheleleyo.
Isishwankathelo, Isikhululo sokutshaja se-EV i-PCB prototyping linyathelo elintsonkothileyo kodwa elibalulekileyo kuyilo kunye nenkqubo yophuhliso.Ifuna ukuqwalaselwa ngononophelo iimfuno zokusebenza, iinkqubo zolawulo lwamandla, ujongano lonxibelelwano, kunye neempawu zokhuseleko. Nangona kunjalo, izibonelelo zeprototyping, ezinjengokuchonga iziphene zoyilo, ukusebenza kovavanyo, kunye nokwenza ngokwezifiso, ukodlula imiceli mngeni. Njengoko imfuno yezikhululo zokutshaja iimoto zombane iqhubeka nokukhula, ukutyala imali kwezi zikhululo zokutshaja zePCBs ngumzamo onexabiso.
