Ngingakwazi ukwenza isibonelo se-PCB esiteshini sokushaja imoto kagesi?

Eminyakeni yamuva nje, izimoto zikagesi (EVs) ziye zanda kakhulu njengezinye izindlela ezingahambisani nemvelo kunezimoto zendabuko zikaphethiloli. Ngenxa yalokho, isidingo seziteshi zokushaja izimoto zikagesi sikhule kakhulu. Lezi ziteshi zokushaja zidlala indima ebalulekile ekwamukelweni okusabalele kwezimoto zikagesi njengoba zinikeza abanikazi indlela elula nesheshayo yokushaja izimoto zabo. Kodwa wenza kanjani i-prototype ibhodi lesifunda eliphrintiwe (PCB) lalezi ziteshi zokushaja?Kulokhu okuthunyelwe kwebhulogi, sizohlola lesi sihloko ngokuningiliziwe futhi sixoxe ngokungenzeka kanye nezinzuzo ze-prototyping PCBs eziteshini zokushaja izimoto zikagesi.

Ukwenza iphrothokholi ye-PCB yanoma yiluphi uhlelo lokusebenza kudinga ukuhlela ngokucophelela, ukuklama, nokuhlola.Nokho, eziteshini zokushaja izimoto zikagesi, ubungozi bukhulu nakakhulu. Lezi ziteshi zokushaja kufanele zithembeke, zisebenze kahle futhi zikwazi ukuphatha ukushaja kwamandla aphezulu. Ngakho-ke, ukuklama i-PCB yalolu hlelo oluyinkimbinkimbi kudinga ubuchwepheshe nokuqonda izidingo ezithile zokushaja kwe-EV.

Isinyathelo sokuqala ekwenzeni i-prototyping esiteshini sokushaja imoto kagesi i-PCB ukuqonda izidingo zokusebenza zohlelo.Lokhu kubandakanya ukunquma izidingo zamandla, izici zokuphepha, izivumelwano zokuxhumana kanye nanoma yikuphi okunye ukucatshangelwa okukhethekile. Uma lezi zidingo sezinqunyiwe, isinyathelo esilandelayo ukuklama amasekhethi nezingxenye ezihlangabezana nalezi zidingo.

Isici esibalulekile sokuklama i-PCB yesiteshi sokushaja i-EV wuhlelo lokuphatha amandla.Isistimu inesibopho sokuguqula okokufaka kwamandla e-AC kusuka kugridi kuya kumandla afanele e-DC adingekayo ukuze kushaje amabhethri e-EV. Iphinde isingatha izici zokuphepha ezehlukene njengokuvikelwa kwe-overcurrent, ukuvikelwa kwesekethe emfushane, nokulawulwa kwamandla kagesi. Ukuklama lolu hlelo kudinga ukucatshangelwa ngokucophelela kokukhethwa kwengxenye, ukuphathwa kwe-thermal, nokuhlelwa kwesifunda.

Esinye isici esibalulekile okufanele sicatshangelwe lapho uklama prototype ye-PCB yesiteshi sokushaja imoto kagesi isixhumi esibonakalayo sokuxhumana.Iziteshi zokushaja izimoto zikagesi ngokuvamile zisekela izivumelwano zokuxhumana ezihlukahlukene njenge-Ethernet, i-Wi-Fi noma ukuxhumana kwamaselula. Lawa maphrothokholi anika amandla ukuqapha okukude, ukuqinisekiswa komsebenzisi, nokucubungula inkokhelo. Ukusebenzisa lezi zindawo zokuxhumana ku-PCB kudinga ukuklama ngokucophelela nokuhlanganiswa nohlelo lokuphatha amandla.

Eziteshini zokushaja izimoto zikagesi, ukuphepha yikona okukhathaza kakhulu.Ngakho-ke, imiklamo ye-PCB kufanele ifake izici eziqinisekisa ukusebenza okuphephile nokuthembekile. Lokhu kuhlanganisa ukuvikela amaphutha kagesi, ukuqapha izinga lokushisa kanye nokuzwa kwamanje. Ukwengeza, ama-PCB kufanele aklanyelwe ukumelana nezimo zemvelo ezinjengomswakama, ukushisa, nokudlidliza.

Manje, ake sixoxe ngezinzuzo zokwenza i-PCB yesiteshi sokushaja imoto kagesi.Ngokwenza i-prototyping PCBs, onjiniyela bangakwazi ukubona amaphutha edizayini futhi benze intuthuko ngaphambi kokukhiqizwa ngobuningi. Ihlola futhi iqinisekise ukujikeleza kwesiteshi sokushaja, ukusebenza nokusebenza. I-Prototyping ingaphinda ihlole izingxenye ezihlukene nobuchwepheshe ukuqinisekisa ukuthi umklamo wokugcina uhlangabezana nokucaciswa okudingekayo.

Ukwengeza, i-prototyping PCBs eziteshini zokushaja izimoto zikagesi kuvumela ukwenziwa ngokwezifiso nokuzivumelanisa nezimfuneko ezithile.Njengoba ubuchwepheshe bezimoto zikagesi buthuthuka, iziteshi zokushaja nazo zingadinga ukubuyekezwa noma ukufakwa kabusha. Ngomklamo we-PCB oguquguqukayo noguquguqukayo, lezi zinguquko zingafakwa kalula ngaphandle kwesidingo sokuklama kabusha okuphelele.

Ngokufigqiwe, Isiteshi sokushaja se-EV i-PCB prototyping iyisinyathelo esiyinkimbinkimbi kodwa esibucayi enqubweni yokuklama nentuthuko.Kudinga ukucatshangelwa ngokucophelela kwezidingo zokusebenza, izinhlelo zokuphatha amandla, izixhumanisi zokuxhumana, nezici zokuphepha. Nokho, izinzuzo ze-prototyping, njengokuhlonza amaphutha edizayini, ukusebenza kokuhlola, nokwenza ngendlela oyifisayo, kunezinselele. Njengoba isidingo seziteshi zokushaja izimoto zikagesi siqhubeka sikhula, ukutshala imali kulawa ma-PCB ayisibonelo seziteshi zokushaja kuwumsebenzi onenzuzo.
