Ukuqinisekisa njani ukhuseleko lwangaphakathi lweebhetri ze-lithium-ion,
Iibhetri zeLithium Ion,

▍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.

Okwangoku, uninzi lweengozi zokhuseleko lweebhetri ze-lithium-ion zenzeke ngenxa yokungaphumeleli kwesiphaluka sokukhusela, okubangela ukuba i-thermal runway yebhetri kwaye ibangele umlilo kunye nokuqhuma.Ke ngoko, ukuze uqaphele ukusetyenziswa okukhuselekileyo kwebhetri ye-lithium, uyilo lwesekethe yokhuseleko lubaluleke kakhulu, kwaye zonke iintlobo zezinto ezibangela ukusilela kwebhetri ye-lithium kufuneka zithathelwe ingqalelo.Ukongeza kwinkqubo yokuvelisa, ukungaphumeleli ngokusisiseko kubangelwa utshintsho kwiimeko ezigqithisileyo zangaphandle, ezifana nokugqithisa, ukukhutshwa ngokugqithisileyo kunye nokushisa okuphezulu.Ukuba ezi parameters zibekwe esweni ngexesha langempela kwaye amanyathelo okukhusela ahambelanayo aya kuthathwa xa atshintsha, ukuvela kwe-thermal runaway kunokugwenywa.Uyilo lokhuseleko lwebhetri ye-lithium lubandakanya iinkalo ezininzi: ukukhethwa kweeseli, ukuyila kwesakhiwo kunye nokuyila ukhuseleko olusebenzayo lwe-BMS.Kukho izinto ezininzi ezichaphazela ukhuseleko lweseli apho ukhetho lwezixhobo zeseli lusisiseko.Ngenxa yeempawu zeekhemikhali ezahlukeneyo, ukhuseleko luyahluka kwizinto ezahlukeneyo ze-cathode zebhetri ye-lithium.Ngokomzekelo, i-lithium iron phosphate imile okwe-olivine, ezinzileyo kwaye akukho lula ukudilika.I-Lithium cobaltate kunye ne-lithium ternary, nangona kunjalo, ziyisakhiwo esinemaleko ekulula ukuwa.Ukukhetha ukwahlula kubaluleke kakhulu, njengoko ukusebenza kwayo kuhambelana ngokuthe ngqo nokhuseleko lweseli.Ke ngoko ekukhetheni iiseli, ayizizo kuphela iingxelo zokubhaqwa kodwa nenkqubo yemveliso yomenzi, imathiriyeli kunye nemilinganiselo yazo iyakuqwalaselwa.Ngenxa yamandla aphezulu ezi bhetri, ubushushu obuveliswayo xa itshaja kwaye ikhutshwa bukhulu.Ukuba ubushushu abukwazi ukuchithwa ngexesha, ubushushu buya kuqokelela kwaye bubangele iingozi.Ngoko ke, ukukhethwa kunye noyilo lwezixhobo ezivaliweyo (Kufuneka ibe namandla athile omatshini kunye neemfuneko zothuli kunye neemfuneko zokungena kwamanzi), ukukhethwa kwenkqubo yokupholisa kunye nokunye ukufakwa kwe-thermal yangaphakathi, ukutshatyalaliswa kobushushu kunye nenkqubo yokucima umlilo kufuneka kuthathelwe ingqalelo.
