Emva kokuqonda uphuhliso lwemarike yenqwaba yokutshaja.- [Malunga neNqwaba yokuTshaja iiMoto zoMbane – Imeko yoPhuhliso lweMarikeSilandele njengoko sijonga nzulu indlela esebenza ngayo isithuba sokutshaja, nto leyo eya kukunceda wenze ukhetho olungcono malunga nendlela yokukhetha isikhululo sokutshaja.

Namhlanje, siza kuqala ngokuxoxa ngeemodyuli zokutshaja kunye neendlela ezisetyenziswa ekuphuhliseni.

1. Intshayelelo kwiimodyuli zokutshaja

Ngokusekelwe kuhlobo lwangoku, olukhoyoiimodyuli zokutshaja ze-evziquka iimodyuli zokutshaja ze-AC/DC, iimodyuli zokutshaja ze-DC/DC, kunye neemodyuli zokutshaja ze-V2G ezibhekisa kwicala elinye. Iimodyuli ze-AC/DC zisetyenziswa kwicala elinyeiinqwaba zokutshaja iimoto zombane, nto leyo eyenza ukuba ibe yeyona modyuli yokutshaja esetyenziswa kakhulu nesetyenziswa rhoqo. Iimodyuli zeDC/DC zisetyenziswa kwiimeko ezifana neebhetri zokutshaja ze-PV zelanga, kunye nokutshaja ibhetri ukuya kwisithuthi, okufumaneka rhoqo kwiiprojekthi zokutshaja zokugcina ilanga okanye iiprojekthi zokutshaja zokugcina. Iimodyuli zokutshaja ze-V2G zenzelwe ukujongana neemfuno zexesha elizayo zonxibelelwano lwegridi yesithuthi okanye ukutshaja kweendlela ezimbini kwizikhululo zamandla.

2. Intshayelelo kwiindlela zoPhuhliso lweeModyuli zokuTshaja

Ngenxa yokusetyenziswa ngokubanzi kwezithuthi zombane, ngokucacileyo iipali zokutshaja ezilula aziyi kwanela ukuxhasa uphuhliso lwazo olukhulu. Indlela yobuchwepheshe yenethiwekhi yokutshaja iye yaba yimvumelwano kwiukutshaja kwesithuthi esitsha samandlaishishini. Ukwakha izikhululo zokutshaja kulula, kodwa ukwakha inethiwekhi yokutshaja kuyinkimbinkimbi kakhulu. Inethiwekhi yokutshaja yinkqubo yendalo ephakathi kwamashishini kunye namacandelo ahlukeneyo, ebandakanya ubuncinci amacandelo obuchwephesha ali-10 afana ne-elektroniki yamandla, ulawulo lokuthunyelwa, idatha enkulu, amaqonga efu, ubukrelekrele bokwenziwa, i-intanethi yemizi-mveliso, ukusasazwa kwesitishi esincinci, ulawulo lokusingqongileyo olukrelekrele, ukuhlanganiswa kwenkqubo, kunye nokusebenza nokugcinwa okukrelekrele. Ukuhlanganiswa okunzulu kwezi teknoloji kubalulekile ukuqinisekisa ukugqibelela kwenkqubo yenethiwekhi yokutshaja.

Umqobo oyintloko wobugcisa kwiimodyuli zokutshaja usekwe kuyilo lwazo lwe-topology kunye nobuchule bokudibanisa. Izinto eziphambili zeemodyuli zokutshaja ziquka izixhobo zamandla, izinto zemagnethi, ii-resistor, ii-capacitors, iitships, kunye nee-PCB. Xa imodyuli yokutshaja isebenza,amandla e-AC amanqanaba amathathuIlungiswa yisekethe yokulungisa amandla asebenzayo (PFC) ize emva koko iguqulwe ibe ngamandla e-DC kwisekethe yokuguqula i-DC/DC. Ii-algorithms zesoftware zomlawuli zisebenza kwiiswitshi zamandla ze-semiconductor kwiisekethe zokuqhuba, ngaloo ndlela zilawula i-voltage yokuphuma kwemodyuli yokutshaja kunye nomsinga wokutshaja ukuze itshaje ipakethi yebhetri. Ulwakhiwo lwangaphakathi lweemodyuli zokutshaja luyinkimbinkimbi, lunezixhobo ezahlukeneyo ngaphakathi kwimveliso enye. Uyilo lwe-topology lumisela ngokuthe ngqo ukusebenza kakuhle kwemveliso kunye nokusebenza kwayo, ngelixa uyilo lwesakhiwo sokusasaza ubushushu lumisela ukusebenza kakuhle kokusasaza ubushushu, zombini zinemida ephezulu yobugcisa.

Njengemveliso ye-elektroniki yamandla enemiqobo yobuchwephesha ephezulu, ukufikelela kumgangatho ophezulu kwiimodyuli zokutshaja kufuna ukuqwalasela iiparameter ezininzi, ezinje ngomthamo, ubunzima, indlela yokusasaza ubushushu, i-voltage yokuphuma, umbane, ukusebenza kakuhle, uxinano lwamandla, ingxolo, ubushushu bokusebenza, kunye nokulahleka kokulinda. Ngaphambili, iipile zokutshaja zazinamandla aphantsi kunye nomgangatho, ngoko ke iimfuno kwiimodyuli zokutshaja zazingekho phezulu. Nangona kunjalo, phantsi komkhwa wokutshaja ngamandla aphezulu, iipile zokutshaja ezikumgangatho ophantsi zinokukhokelela kwiingxaki ezinkulu ngexesha lesigaba sokusebenza esilandelayo seeppile zokutshaja, oko kwandise iindleko zokusebenza kunye nokugcinwa kwexesha elide. Ke ngoko,abavelisi beenqwaba zokutshajaKulindeleke ukuba zinyuse ngakumbi iimfuno zazo zomgangatho weemodyuli zokutshaja, zibeke iimfuno eziphezulu kubuchule bobuchwephesha babavelisi beemodyuli zokutshaja.

Oko kuqukumbela ukwabelana namhlanje ngeemodyuli zokutshaja ze-EV. Siza kwabelana ngomxholo oneenkcukacha ngakumbi kamva ngezi zihloko:

1. Ukulungiswa kwemodyuli yokutshaja
2. Uphuhliso oluya kwiimodyuli zokutshaja ezinamandla aphezulu
