▍Siyini Isitifiketi se-PSE?

I-PSE (Ukuphepha Komkhiqizo Kwezinto Ezisetshenziswa Kagesi Nezinto Zokusebenza) iwuhlelo lwesitifiketi oluyisibopho e-Japan. Kuphinde kubizwe ngokuthi 'Ukuhlola Ukuthobela' okuwuhlelo oluyimpoqo lokufinyelela emakethe ezintweni ezisebenza ngogesi. Isitifiketi se-PSE sakhiwe izingxenye ezimbili: i-EMC nokuphepha komkhiqizo futhi kuwumthetho obalulekile womthetho wokuphepha wase-Japan ezintweni zikagesi.

▍ Izinga Lokuqinisekisa lamabhethri e-lithium

Ukutolikwa kwe-METI Ordinance Yezimfuneko Zobuchwepheshe(H25.07.01)，Isithasiselo 9,Amabhethri esibili e-Lithium ion

▍Kungani i-MCM?

● Izakhiwo ezifanelekayo: I-MCM ifakwe izinsiza ezifanelekayo ezingafinyelela kuwo wonke amazinga okuhlola e-PSE kanye nokuhlolwa kokwenza okuhlanganisa ukujikeleza okufushane kwangaphakathi okuphoqelelwe njll. Isenza sikwazi ukunikeza imibiko yokuhlola eyenziwe ngokwezifiso ngefomethi ye-JET, TUVRH, ne-MCM njll. .

● Usekelo lwezobuchwepheshe: I-MCM inethimba elichwepheshile lonjiniyela bezobuchwepheshe abangu-11 abakhethekile kumazinga nemithetho yokuhlola ye-PSE, futhi iyakwazi ukunikeza imithetho nezindaba zakamuva ze-PSE kumakhasimende ngendlela enembile, ebanzi futhi esheshayo.

● Isevisi ehlukahlukene: I-MCM ingakhipha imibiko ngesiNgisi noma ngesi-Japanese ukuze ihlangabezane nesidingo samakhasimende. Kuze kube manje, i-MCM isiqedele amaphrojekthi we-PSE angaphezu kuka-5000 kumakhasimende esewonke.

Ukuphepha kohlelo lokugcina 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 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 kokucindezela, futhi umshini wokuqeda igesi uyavuleka (T2). Ngalesi sikhathi, igesi eningi, ama-electrolyte nezinye izinto zikhulula, zisuse ingxenye yokushisa, futhi izinga lokushisa elikhulayo liba libi.
