Kubakholwa beprojekthi (Engineering, Procurement and Construction), ukukhetha umnisi wobatteri yelithiyamu obuhle akuyi nje indima yokuthenga - yindlela yokuphatha imikhumbi yokucinga. Kuziprojekthi zokugcina imfuyo yobatteri zokugcina imfuyo yobatteri, amakhotho okukhulu kwezindlela, ukungafaneleka kwesikhathi, nokufa kungakwazi ukubonakala ngokupheleleyo ngokugcina kwezinto zokusebenza. Kodwa, lezi zinto zihlala zibuyela kuselwa kwabasindisi. Umsebenzi owawuselwa ngokungafanele ngumsebenzi wokuselwa kwabasindisi ungase kubangela ukuthi isikhathi sokuvulwa kushintshwe, izinkinga zokuhlanganisa izinhlayo, izinkinga zemiphumela yokubhala, nokukhulu kwezindlela zokusebenza phakathi kwesikhathi sokusebenza. Lezi zindlela zonke ziyathatha umphumela wokuthi umsebenzi wokuzimela (EPC) uzobona ukuthi akhethwe ngokupheleleyo futhi ukuqinisekisa ubuchwepheshe bokusebenza kwesikhathi esithile—futhi lezi zinkinga zonke ziyizidingo zokubalwa ngumsebenzi wokuzimela (EPC) ngokupheleleyo ngokulinganiswe nesikhathi nezindlela zokusebenza. Ezilandelayo kukhona izindlela ezintathu zokuhlola ukuthi abasindisi bakhiyana ngamabhasi e-lithium bakhethwe ngokupheleleyo ukuthi amaprojekthi ayizindaba zokupheleleyo.
Kungani Ukuthi Ukusebenza Kwamaphrojekthi Nokubhalwa Kwamaprojekthi Kuyisidingo
Iqala ngokwesayensi yokuprodukha. Ukuhambisana kwezindawo zokuprodukha kusobala ukuthi umsunguli wakho uzokubona izikhathi zokuprodukha ngokuphelele, ukuhambisa isithu esifanayo ngosuku sonke, nokuvula ukuprodukha ngokwesikhathi sokufuna kwendlela yomphilo waprojekthi. Abamsunguli beshilini (EPCs) kufanele babhalise ubude bekubukwa kwemsunguli: iziphi izinyathelo zokuprodukha zokho zizokwenziwa ngaphandle, ukuthi iphi inani lezinkambo zokuhlinzekwa kuzokwenziwa, futhi ukuthi izinyathelo ezibalulekile zokugcina zizokwenziwa ngaphandle kwezindawo zokuprodukha.
Izindlela eziphikisana nokuqinisa ukuthi umsunguli uyasebenza ngokuphelele kukhona izimboni zokuhlinzekwa okuphelele, ukuthi isithu sikhuluma ngokuphelele, nokuthi kuyasebenza ukuthi kuzokwenziwa ukuchaza okuphelele. Kufanele kubhekwe ukuthi abamsunguli abasebenzisa amathuba amaningi ekuphatheni amasayensi asezingeni eliphelele abazi ukuthi kuzokwenzeka kanjani ukuthi le masayensi ayisiphumo sokuphatha kwezinye izinhlangano – lokhu kuyisibonelo sokuthi abamsunguli beshilini (EPCs) bafuna umsunguli owenziwe ngokuphelele, okuyinto engeyona isibonelo sokuthi abamsunguli beshilini (EPCs) bafuna umsunguli owenziwe ngokuphelele, okuyinto engeyona isibonelo sokuthi abamsunguli beshilini (EPCs) bafuna umsunguli owenziwe ngokuphelele.
Amathuba okuphinde kakhulu akubonisa ukuthi kuyisipho esihle. Abaprojekthi bayaqonda ukuthi umthwakuli wasebenza njani ngokwesikhathi sokusebenzisa amaprojekthi, ukusebenza kwakhe, nokuthandwa kwaqo ngokwesibonelo sokuthi abaphathi basebenzisa nebabhalisi bakhiyise ("ukwakha imali"). Abaprojekthi abanembono emhlabeni wonke bayaqhubeka ngokulungisa ukuthi kufuneka kusoloko kubhalwe noma kubhalwe ngokusha, futhi bayaqhubeka ngokulungisa ukuthi kufuneka kubhalwe ngokusha. Ukuthi kunezinkambo eziningi zeziprojekthi zikubonisa ukuthi kunezindlela ezilungileyo zokubhalwa, ukuthi kuzoyintsha ukuthi kufanele kubhalwe ngokusha, nokuthi kunezinto zonke ezingafuneki ukuthi zibhalwe ngokusha—kuyabuyisa isikhathi sonke isinye sesinye sokugcina iprojekthi.
Izindaba Zokuphepha Okumangalisayo Ezifunekayo Ukuzwa Ngabaprojekthi
Ukufaneleka komuntu kuqinisekiswa ngokucacile ngokusebenzisa izinkomba zomsebenzi. Ama-EPC kuyodingeka abheke irekhodi lomkhiqizi lokuthuthukiswa okuqediwe, ukusebenza okuqhubekayo, futhi okubaluleke kakhulu, ukwamukelwa ngababolekisi nabomshuwalense ("ukukhokhelwa kwebhange"). Abakhiqizi abanomlando omningi wokusetshenziswa kwamanye amazwe banganciphisa ukuxabana okuhlobene nezimali zephrojekthi futhi basheshise inqubo yokuthola imvume; ngokufanayo, ukubonakala komhlaba wonke, ngamashumi ezinkulungwane zamaphrojekthi afakwe emhlabeni wonke, kusho ukuthi abakhiqizi abanjalo banezinqubo zokufaka kahle, ukuqonda kahle imithetho
Ama-EPC adinga ukuhlola ukuthi ngabe kukhona yini izitifiketi ezifanele ezimakethe zawo azikhethile. I-Major Certified ingachazwa kanje:
IEC 62619: Izinga lokuhlukunyezwa ngokushisa, ukulayishwa ngokweqile nokukhishwa okuphoqelelwe kwamabhethri aqukethwe kuwo kanye nokuhlolwa kwephutha langaphakathi kwamabhethri e-lithium asetshenziswa ezimbonini
UL 1973: I-North American Standard enezivivinyo ezigcwele zezinhlelo zokusebenza zokugcina ezihleliwe nge-Thermal Runaway, ukuchayeka emlilweni nokuhlukunyezwa ngokomzimba
UN38.3: Kuyadingeka ukuqinisekisa ukuphepha kokuthumela amabhethri e-lithium. Nakuba ukuphepha kufanele kuqale ezingeni lokuhlanganiswa kohlelo, zonke izinhlaka ngeke zikwazi ukuqinisekisa ukuphepha ngaphandle uma sekuqalile kakade yizakhi ze-EPC kufanele zinake ukuphepha kusukela ekwakhiweni kwemikhiqizo yazo maqondana nokuphathwa kokushisa, ukuthola nokucisha imililo, ukuhlukanisa amaphutha nokunciphisa ingozi yokuq Eqinisweni, ama-EPC angase agxile ekutheni umphakeli uwubhala kahle kangakanani umqondo osebenza ngokuphepha kwawo hhayi nje ekuhlangabezaneni nemigomo yokuphepha okukhulunywa ngayo.
Ukukhetha Abalingani Bebhethri Abasekela Amaphrojekthi Angaphambi Kokulethwa
Nokho, umuzwa wangempela wenani lomlingani othembekile ungase ungaqondakali ngokugcwele kuze kube yilapho enikezwa. Futhi njengoba ama-EPC engase abe yiwona aphethe izitshalo ezansi emgqeni phakathi nomjikelezo wokuphila wesitshalo seminyaka engu-10-15, ukwesekwa kwezobuchwepheshe/izinsizakalo zangemva kokuthengisa kuyizindlela zokuqala ezibalulekile zokunquma ukuthenga.
Ama-EPC kufanele ahlole ukuthi ngabe umenzi unikeza uhla lwezinsizakalo zomjikelezo wokuphila:
Ukuqapha nokuxilonga okukude: Ukuqoqwa kwedatha yesikhathi sangempela kusuka kumaseli, amamojula, i-BMS, ne-PCS ukuze kutholakale ngempela ukungafani ngaphambi kokuba kube ukwehluleka.
Ukuhlanganiswa kwe-BMS ne-EMS: Ukuzisekela kwesofthiwe kuyadingeka - amakhasimende ancike ngokuphelele kwisofthiwe ye-EMS yeqembu lesithathu azohlangabezana nokubambezeleka ngokuhlanganiswa nokudideka mayelana nobunikazi bezobuchwepheshe.
Izingxenye ezisele zokuthutha: Izingxenye - Ukutholakala ngesikhathi esibekiwe kanye nokutholakala esitokisini ngezifunda kanye nokushintshwa kwamayunithi ezakhi, amaseli, amamojula, amakhadi e-BMS nezingxenye ezishisayo.
Inkonzo yasensimini yasendaweni kanye nokugcinwa okuvimbelayo: Amathuba okukhethwa, nokuhlola. Ukucheka isistimu, nokulungisa. Amahlolo esilungisiwe nokuqwalasela.
Ukubhukuda kwezinkundla zokusiza ezizweni nezizwe: Abasebenzisi/abathengi bamasini abaphakathi kwabo abanekhaya lezinkundla zokusiza ebanda lokusebenza kuzoba yinkululeko eyenkulu/kunciphisa izikhathi zokungasebenzi kwezinye zamasini abo.
Sisho ukuthi kufanele siboneleke ngokuphelele isithembiso sokugcina isikhathi eside. Isibonelo, sisho ukuthi i-EPCs zifanele zihlolise isikhondlo sokugcina ubukhulu besithembiso, iziqinisekiso zezindlela zokubala isivinini sokugcina ubukhulu, nokuthi njani okwenzelwa ukubala "isikhathi sokusebenza". Ukubonakala kokuthi kuyisiphi isikhondlo sokwenza kuyakuvumela ukubala okuphelele kwemali futhi kungavunywe izinkinga emva kokusebenza nokulungisa.
Ngenxa yokuthi WTHD
I-Shenzhen Weitu Hongda Industrial Co., Ltd (WTHD), indawo yokuqasha yezinsizakalo zokuphatha izindaba zokusebenza kwe-UPS, izinhlanganisi zokugcina amandla we-solar, nokugcina amandla, iya kwenza umsebenzi wokuthi “indawo yokuqala eyodwa, amabase amathathu” eShenzhen, eFoshan, neHenan, ngokuvumelana nge-ISO 9001, TLC, CE, FCC. Uma ufuna ukwazi inkabanzi ngamabhatari we-lithium okukhetha kwezinsizakalo zokugcina amandla okufanele kwezinsizakalo ze-EPC, sicela ubone isitayela se-engineering se-WTHD.
