Momwe mungawonetsere chitetezo chamkati cha mabatire a lithiamu-ion,
Mabatire a Lithium Ion,

▍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.

Pakalipano, ngozi zambiri zachitetezo cha mabatire a lithiamu-ion zimachitika chifukwa cha kulephera kwa dera lachitetezo, zomwe zimapangitsa kuti batire yotenthetsera kuthawa ndipo imayambitsa moto ndi kuphulika. Chifukwa chake, kuti muzindikire kugwiritsa ntchito motetezeka kwa batire ya lithiamu, kapangidwe kake kachitetezo ndikofunikira kwambiri, ndipo mitundu yonse ya zinthu zomwe zimayambitsa kulephera kwa batire ya lithiamu ziyenera kuganiziridwa. Kuphatikiza pa kupanga, zolephera zimayamba chifukwa cha kusintha kwa zinthu zakunja, monga kuchulukitsa, kutulutsa kwambiri komanso kutentha kwambiri. Ngati magawowa akuyang'aniridwa mu nthawi yeniyeni ndipo njira zodzitetezera zidzatengedwa zikasintha, zochitika za kuthawa kwa kutentha zingathe kupewedwa. Kukonzekera kwa chitetezo cha batri ya lithiamu kumaphatikizapo zinthu zingapo: kusankha kwa maselo, mapangidwe apangidwe ndi mapangidwe a chitetezo cha BMS. Chifukwa cha mankhwala osiyanasiyana, chitetezo chimasiyanasiyana muzinthu zosiyanasiyana za cathode za batri ya lithiamu. Mwachitsanzo, lithiamu iron phosphate imakhala ngati olivine, yomwe imakhala yokhazikika komanso yosavuta kugwa. Lithium cobaltate ndi lithiamu ternary, komabe, ndizomwe zimakhala zosavuta kugwa. Kusankhidwa kwa olekanitsa ndikofunikanso kwambiri, chifukwa ntchito yake ikugwirizana mwachindunji ndi chitetezo cha selo. Chifukwa chake posankha ma cell, osati malipoti ozindikira okha komanso momwe wopanga amapangira, zida ndi magawo ake ziyenera kuganiziridwa. Chifukwa cha mphamvu zambiri zamabatirewa, kutentha komwe kumapangidwa poyitanitsa ndi kutulutsa kumakhala kwakukulu. Ngati kutentha sikungatheke panthawi yake, kutentha kumachulukana ndipo kumabweretsa ngozi. Chifukwa chake, kusankha ndi kapangidwe ka zida zotsekera (ziyenera kukhala ndi mphamvu zamakina komanso zofunikira zoletsa fumbi komanso zosalowa madzi), kusankha kwa njira yozizira ndi zina zamkati zamatenthedwe, kutulutsa kutentha ndi kuzimitsa moto ziyenera kuganiziridwa.
