▍Siyini Isitifiketi Se-CB?

I-IECEE CB iwuhlelo lokuqala lwangempela lwamazwe ngamazwe lokuqashelwa ngokufanayo kwemibiko yokuhlolwa kokuphepha kwezinto zikagesi. I-NCB (National Certification Body) ifinyelela isivumelwano sezizwe eziningi, esivumela abakhiqizi ukuthi bathole isitifiketi sikazwelonke kwamanye amazwe angamalungu ngaphansi kohlelo lwe-CB ngesisekelo sokudlulisa esinye sezitifiketi ze-NCB.

Isitifiketi se-CB siwumbhalo osemthethweni wohlelo lwe-CB okhishwe i-NCB egunyaziwe, okokwazisa enye i-NCB ukuthi amasampula omkhiqizo ohloliwe ahambisana nezidingo ezijwayelekile.

Njengohlobo lombiko omisiwe, umbiko we-CB ubala izidingo ezifanele ezivela entweni ejwayelekile ye-IEC ngento ngayinye. Umbiko we-CB awuhlinzeki nje kuphela ngemiphumela yakho konke ukuhlolwa okudingekile, ukukalwa, ukuqinisekiswa, ukuhlolwa nokuhlola ngokucacile nokungacacisi, kodwa futhi kufaka phakathi izithombe, umdwebo wesifunda, izithombe nencazelo yomkhiqizo. Ngokomthetho wohlelo lwe-CB, umbiko we-CB ngeke usebenze kuze kube yilapho wethula isitifiketi se-CB ndawonye.

▍Kungani sidinga Isitifiketi se-CB?

1. Ngqolyqaphelazed or vumaedngeilunguamazwe

Ngesitifiketi se-CB kanye nombiko wokuhlola we-CB, imikhiqizo yakho ingathunyelwa kwamanye amazwe ngokuqondile.

1. Guqulela kwamanye amazwe izitifiketi

Isitifiketi se-CB singaguqulelwa ngokuqondile kusitifiketi samazwe angamalungu ayo, ngokunikeza isitifiketi se-CB, umbiko wokuhlola kanye nombiko wokuhlola umehluko (uma kusebenza) ngaphandle kokuphinda ukuhlolwa, okunganciphisa isikhathi sokuhola sokuthola isitifiketi.

1. Qinisekisa Ukuphepha Komkhiqizo

Ukuhlolwa kwesitifiketi se-CB kubheka ukusetshenziswa okuphusile komkhiqizo kanye nokuphepha okubonakalayo uma usetshenziswa kabi. Umkhiqizo oqinisekisiwe ufakazela ukugculisa kwezidingo zokuphepha.

▍Kungani i-MCM?

● Ukufaneleka:I-MCM iyi-CBTL yokuqala egunyaziwe ye-IEC 62133 ejwayelekile yi-TUV RH ezweni laseChina.

● Isitifiketi namandla okuhlola:I-MCM iphakathi kwesiqephu sokuqala sokuhlola nesitifiketi senkampani yangaphandle ye-IEC62133 ejwayelekile, futhi isiqede ukuhlola amabhethri e-IEC62133 angaphezu kuka-7000 kanye nemibiko ye-CB kumakhasimende omhlaba.

● Usekelo lobuchwepheshe:I-MCM inonjiniyela bezobuchwepheshe abangaphezu kwe-15 abakhethekile ekuhlolweni njengokujwayelekile kwe-IEC 62133. I-MCM ihlinzeka amakhasimende ngohlobo oluphelele, olunembile, oluvaliwe losekelo lobuchwepheshe kanye nezinsizakalo zolwazi ezihola phambili.

Ukuphepha kwesistimu yokugcina amandla kuyinto evamile. Njengenye yezingxenye ezibalulekile zesistimu yokugcina amandla, ukuphepha kwebhethri ye-lithium-ion kubaluleke kakhulu. Njengoba ukuhlolwa kokubaleka okushisayo kungahlola ngokuqondile ingozi yomlilo oyenzeka kusistimu yokugcina amandla, amazwe amaningi asungule izindlela zokuhlola ezihambisanayo kumazinga awo ukuze kuhlolwe ingozi yokubaleka okushisayo. Isibonelo, i-IEC 62619 ekhishwe yi-International Electrotechnical Commission (IEC) ibeka indlela yokusabalalisa yokuhlola umthelela wokubaleka okushisayo kweseli; Izinga lezwe laseShayina le-GB/T 36276 lidinga ukuhlolwa kokushisa okushisayo kweseli nokuhlolwa kokushisa okushisayo kwemojuli yebhethri; I-US Underwriters Laboratories (UL) ishicilela amazinga amabili, i-UL 1973 kanye ne-UL 9540A, womabili ahlola imiphumela yokushisa okushisayo. I-UL 9540A yakhelwe ngokukhethekile ukuhlola kusuka kumazinga amane: iseli, imojula, ikhabethe, nokusabalalisa ukushisa ezingeni lokufaka. Imiphumela yokuhlolwa kwe-thermal runnaway ayikwazi nje ukuhlola ukuphepha kukonke kwebhethri, kodwa futhi isivumela ukuthi siqonde ngokushesha ukugijima kwamaseli, futhi inikeze imingcele eqhathanisekayo yomklamo wokuphepha wamaseli anamakhemikhali afanayo. Iqembu elilandelayo lokuhlola idatha yokubaleka okushisayo elokuthi uqonde izici zokubaleka okushisayo esigabeni ngasinye nezinto ezikuseli.Isigaba 1: Izinga lokushisa liyenyuka kancane ngomthombo wokushisisa wangaphandle. Ngalesi sikhathi, izinga lokukhiqiza ukushisa kweseli ngu-0℃/min (0~ T1), iseli ngokwalo alishisi, futhi akukho ukusabela kwamakhemikhali ngaphakathi.Isigaba sesi-2 ukubola kwe-SEI. Ngokukhuphuka kwezinga lokushisa, ifilimu ye-SEI iqala ukuncibilika lapho ifinyelela cishe ku-90℃ (T1). Ngalesi sikhathi, iseli lizoba nokukhululwa okuncane kokuzishisa, futhi kungabonakala kuMfanekiso 1(B) ukuthi izinga lokushisa liyashintshashintsha.Isigaba sesi-3 yisigaba sokubola kwe-electrolyte (T1~ T2). Lapho izinga lokushisa lifinyelela ku-110 ℃, i-electrolyte kanye ne-electrode engalungile, kanye ne-electrolyte ngokwayo kuzokwenzeka uchungechunge lokusabela kokubola, okukhiqiza inani elikhulu legesi. Igesi eqhubekayo yenza ukucindezela ngaphakathi kweseli kukhuphuke kakhulu, kufinyelele inani lokukhululeka kwengcindezi, futhi kuvuleke indlela yokukhipha igesi (T2). Ngalesi sikhathi, igesi eningi, ama-electrolyte nezinye izinto zikhulula, zisuse ingxenye yokushisa, futhi izinga lokushisa elikhulayo liba libi.
