▍ Chii chinonzi cTUVus & ETL CERTIFICATION?
OSHA (Occupational Safety and Health Administration), yakabatana neUS DOL (Department of Labor), inoda kuti zvigadzirwa zvese zvinofanirwa kushandiswa munzvimbo yebasa zviongororwe nekupihwa zvitupa neNRTL zvisati zvatengeswa pamusika. Miyero yekuyedza inoshanda inosanganisira American National Standards Institute (ANSI) zviyero; American Society for Testing Material (ASTM) zviyero, Underwriter Laboratory (UL) zviyero, uye fekitori mutual-recognition sangano zviyero.
▍OSHA, NRTL, cTUVus, ETL uye UL tsananguro yematemu nehukama
OSHA:Kupfupisa kweOccupational Safety uye Health Administration. Iyo mubatanidzwa weUS DOL (Dhipatimendi reVashandi).
NRTL:Kupfupisa kweNationally Recognized Testing Laboratory. Ndiyo inotarisira kubvumidzwa kwe lab. Kusvika parizvino, kune gumi nemasere echitatu-bato rekuyedza masangano akabvumidzwa neNRTL, kusanganisira TUV, ITS, MET zvichingodaro.
cTUVus:Certification chiratidzo cheTUVRh muNorth America.
ETL:Kupfupisa kweAmerican Electrical Testing Laboratory. Yakavambwa muna 1896 naAlbert Einstein, muvambi weAmerica.
UL:Nhoroondo ye Underwriter Laboratories, Inc.

▍ Neiko MCM?
● Tsigiro yakapfava kubva kuhunyanzvi uye tekinoroji:Seyapupu yekuyedza lab yeTUVRH neITS muNorth America Certification, MCM inokwanisa kuita marudzi ese ekuyedza uye nekupa sevhisi iri nani nekuchinjana tekinoroji chiso nechiso.
● Tsigiro yakaoma kubva kune tekinoroji:MCM inoshongedzerwa nemidziyo yese yekuyedza mabhatiri ehukuru-hukuru, diki-hukuru uye chaiyo mapurojekiti (kureva yemagetsi nharembozha, simba rekuchengetera, uye zvigadzirwa zvemagetsi edhijitari), inokwanisa kupa bhatiri rese rekuyedza uye masevhisi etifiketi muNorth America, inovhara zviyero. UL2580, UL1973, UL2271, UL1642, UL2054 zvichingodaro.
Kuchengetedzwa kwesimba rekuchengetedza sisitimu chinhu chinowanzoitika. Sechimwe chezvinhu zvakakosha zvesimba rekuchengetedza sisitimu, kuchengetedzwa kwe lithium-ion bhatiri kunonyanya kukosha. Sezvo kupisa kwekupisa bvunzo kunogona kuongorora zvakananga njodzi yemoto inoitika musimba rekuchengetedza sisitimu, nyika zhinji dzakagadzira dzinoenderana nzira dzekuyedza mumiyero yadzo yekuongorora njodzi yekutiza kwekupisa. Semuyenzaniso, IEC 62619 yakapihwa neInternational Electrotechnical Commission (IEC) inotaura nzira yekuparadzira yekuongorora pesvedzero yekutiza kwekupisa kwesero; Chinese national standard GB/T 36276 inoda kupisa kunotiza kuongororwa kwesero uye kupisa kunotiza bvunzo yebhatiri module; Iyo US Underwriters Laboratories (UL) inoburitsa zviyero zviviri, UL 1973 uye UL 9540A, ese ari maviri anoongorora kupisa kwekupisa mhedzisiro. UL 9540A yakanyatsogadzirirwa kuongorora kubva kumatanho mana: sero, module, kabati, uye kuparadzira kupisa padanho rekuisa. Mhedzisiro yekudziya kwekupisa bvunzo haigone kungoongorora kuchengetedzwa kwese kwebhatiri, asi zvakare inotitendera kuti tikurumidze kunzwisisa kupisa kunotiza kwemasero, uye kupa maparamendi akafanana ekuchengetedza dhizaini yemasero ane makemikari akafanana. Iri rinotevera boka rekuyedza data rekutiza kwekupisa nderekuti iwe unzwisise hunhu hwekupisa kwekupisa padanho rega rega uye zvinhu zviri muchitokisi. Nhanho yechitatu ndiyo nhanho yekuparara kwe electrolyte (T1~ T2). Kana tembiricha yasvika 110 ℃, iyo electrolyte uye iyo yakaipa electrode, pamwe neiyo electrolyte pachayo ichaitika nhevedzano yekuora maitiro, ichiburitsa huwandu hukuru hwegasi. Iyo inoramba ichigadzira gasi inoita kuti kudzvanywa kwemukati mesero kuwedzere zvakanyanya, ichisvika pakudzvinyirira kukosha, uye gasi rinopedza simba rinovhura (T2). Panguva ino, gasi rakawanda, electrolytes uye zvimwe zvinhu zvinoburitswa, zvichibvisa chikamu chekupisa, uye tembiricha inowedzera inova yakaipa.
