▍Kodi PSE Certification ndi chiyani?

PSE (Product Safety of Electrical Appliance & Material) ndi dongosolo lovomerezeka la certification ku Japan. Imatchedwanso 'Compliance Inspection' yomwe ndi njira yovomerezeka yofikira pamsika ya zida zamagetsi. Chitsimikizo cha PSE chimapangidwa ndi magawo awiri: EMC ndi chitetezo chazinthu komanso ndi lamulo lofunikira lalamulo lachitetezo ku Japan pazida zamagetsi.

▍ Certification Standard ya mabatire a lithiamu

Kutanthauzira kwa METI Ordinance for Technical Requirements(H25.07.01), Appendix 9, Lithium ion secondary mabatire

▍Chifukwa chiyani MCM?

● Malo oyenerera: MCM ili ndi malo oyenerera omwe angakhale ndi miyezo yonse yoyezetsa ya PSE ndi kuyesa kuyesa kuphatikizapo kukakamiza mkati mwafupifupi dera ndi zina. Imatithandiza kupereka malipoti osiyanasiyana oyesera mosiyanasiyana mumtundu wa JET, TUVRH, ndi MCM etc. .

● Thandizo laukadaulo: MCM ili ndi gulu la akatswiri 11 akatswiri aukadaulo okhazikika pamiyezo ndi malamulo oyezetsa a PSE, ndipo amatha kupereka malamulo atsopano a PSE ndi nkhani kwa makasitomala mwatsatanetsatane, mwatsatanetsatane komanso mwachangu.

● Ntchito zosiyanasiyana: MCM ikhoza kupereka malipoti mu Chingerezi kapena Chijapani kuti ikwaniritse zosowa za makasitomala. Pakadali pano, MCM yamaliza ntchito zopitilira 5000 za PSE zamakasitomala onse.

Mtundu watsopano wa UL 1642 unatulutsidwa. Njira ina yoyesera yolemetsa imawonjezedwa pama cell athumba. Zofunikira zenizeni ndi izi: Kwa selo la thumba lomwe lili ndi mphamvu zoposa 300 mAh, ngati kuyesedwa kolemera sikunapitirire, akhoza kuyesedwa ndi Gawo 14A kuzungulira ndodo extrusion test.Pouch cell ilibe vuto lolimba, lomwe nthawi zambiri limayambitsa kuphulika kwa ma cell, kuthyoka kwa ma tap, zinyalala zomwe zikuwulukira kunja ndi kuwonongeka kwina kwakukulu komwe kumachitika chifukwa cha kulephera pamayeso amphamvu, ndipo zimapangitsa kuti zikhale zosatheka kuzindikira dera lalifupi lamkati lomwe limayambitsidwa ndi vuto la kapangidwe kake kapena kuwonongeka kwa dongosolo. Ndi kuyesa kozungulira ndodo, zolakwika zomwe zingatheke mu cell zitha kudziwika popanda kuwononga ma cell. Kuwunikiridwaku kudapangidwa poganizira izi. Ikani chitsanzo pamalo athyathyathya. Ikani ndodo yozungulira yachitsulo yokhala ndi mainchesi 25 ± 1mm ​​pamwamba pa chitsanzo. Mphepete mwa ndodo iyenera kugwirizanitsidwa ndi pamwamba pa nsonga ya selo, ndi chigawo choyima cha perpendicular to tabu (FIG. 1). Utali wa ndodo uyenera kukhala wosachepera 5mm m'lifupi kuposa m'mphepete mwachitsanzo choyesera. Kwa ma cell okhala ndi ma tabo abwino ndi oyipa mbali zotsutsana, mbali iliyonse ya tabu iyenera kuyesedwa. Mbali iliyonse ya tabu iyenera kuyesedwa pazitsanzo zosiyanasiyana.  Kuyeza makulidwe (kulolera ± 0.1mm) kwa maselo kumayenera kuchitidwa asanayesedwe molingana ndi Zowonjezera A za IEC 61960-3 (Maselo achiwiri ndi mabatire omwe ali ndi alkaline kapena ena omwe si- ma electrolyte acidic - Ma cell achiwiri a lithiamu ndi mabatire - Gawo 3: Ma cell a prismatic ndi cylindrical lithiamu sekondale ndi mabatire
