▍Yintoni i-PSE Certification?

I-PSE (uKhuseleko lweMveliso yesiXhobo soMbane kunye neMathiriyeli) yinkqubo yoqinisekiso olunyanzelekileyo eJapan. Ikwabizwa ngokuba 'UHlolo lokuThobela' olusisixokelelwano esisisinyanzelo sokufikelela kwimarike kwisixhobo sombane. Isatifikethi se-PSE senziwe ngamacandelo amabini: i-EMC kunye nokhuseleko lwemveliso kwaye ikwangummiselo obalulekileyo womthetho wokhuseleko waseJapan kwisixhobo sombane.

▍Umgangatho weSatifikethi seebhetri ze-lithium

Utoliko lwe-METI Ordinance yeeMfuno zobuGcisa (H25.07.01), iSihlomelo 9, iibhetri zesekondari zeLithium ion

▍Kutheni i-MCM?

● Amaziko afanelekileyo: I-MCM ixhotyiswe ngamaziko afanelekileyo anokuthi afikelele kuyo yonke imigangatho yovavanyo lwe-PSE kunye novavanyo lokuqhuba olubandakanya ukunyanzeliswa kwesiphaluka esifutshane sangaphakathi njl. .

● Inkxaso yobugcisa: I-MCM ineqela leenjineli ze-11 zobuchwephesha ezikhethekileyo kwimigangatho yokuvavanya i-PSE kunye nemimiselo, kwaye iyakwazi ukubonelela ngemigaqo ye-PSE yamva nje kunye neendaba kubaxhasi ngendlela echanekileyo, ebanzi kwaye ekhawulezayo.

● Inkonzo eyohlukeneyo: I-MCM inokukhupha iingxelo ngesiNgesi okanye ngesiJapan ukuhlangabezana neemfuno zabaxumi. Ukuza kuthi ga ngoku, i-MCM igqibe ngaphezulu kwama-5000 eeprojekthi ze-PSE kubathengi bebonke.

Ukhuseleko lwenkqubo yokugcina amandla yinkxalabo eqhelekileyo. Njengenye yezinto ezibalulekileyo zenkqubo yokugcina amandla, ukhuseleko lwebhetri ye-lithium-ion lubaluleke kakhulu. Njengoko uvavanyo lokubaleka kwe-thermal lunokuvavanya ngokuthe ngqo umngcipheko womlilo owenzeka kwinkqubo yokugcina amandla, amazwe amaninzi aphuhlise iindlela zovavanyo ezihambelanayo kwimigangatho yazo yokuvavanya umngcipheko wokubaleka kwe-thermal. Ngokomzekelo, i-IEC 62619 ekhutshwe yi-International Electrotechnical Commission (IEC) ichaza indlela yokusabalalisa ukuvavanya impembelelo ye-thermal runaway yeseli; Umgangatho wesizwe saseTshayina i-GB/T 36276 ifuna ukuvavanywa kobushushu bokufudumala kweseli kunye novavanyo lokubaleka kwe-thermal kwimodyuli yebhetri; I-US Underwriters Laboratories (UL) ipapasha imigangatho emibini, i-UL 1973 kunye ne-UL 9540A, zombini ezo zivavanya iziphumo zokubaleka kwe-thermal. I-UL 9540A yenzelwe ngokukodwa ukuvavanya kumanqanaba amane: iseli, imodyuli, ikhabhinethi, kunye nokusasazwa kobushushu kwinqanaba lofakelo. Iziphumo zovavanyo lokubaleka kwe-thermal azikwazi nje ukuvavanya ukhuseleko olupheleleyo lwebhetri, kodwa zikwavumela ukuba siqonde ngokukhawuleza ukubaleka kwe-thermal yeeseli, kunye nokubonelela ngeeparitha ezifanayo zoyilo lokhuseleko lweeseli ezinekhemistri efanayo. Eli qela lilandelayo lovavanyo lwedatha ye-thermal runaway kukuba uqonde iimpawu ze-thermal runaway kwinqanaba ngalinye kunye nezinto ezikwiseli.
Inqanaba lesi-3 linqanaba lokubola kwe-electrolyte (T1~ T2). Xa ubushushu bufikelela kwi-110℃, i-electrolyte kunye ne-electrode engalunganga, kunye ne-electrolyte ngokwayo iya kwenzeka uthotho lokusabela kokubola, ukuvelisa isixa esikhulu segesi. Igesi eqhubekayo yenza uxinzelelo ngaphakathi kwiseli lunyuke ngokukhawuleza, lufikelele kwixabiso lokunciphisa uxinzelelo, kwaye i-gas exhausting mechanism ivula (T2). Ngeli xesha, igesi eninzi, i-electrolytes kunye nezinye izinto zikhupha, zithatha indawo yobushushu, kwaye izinga lobushushu elikhulayo liba libi.
