Iibhetri ze-Lithium-ion zokuGcinwa kwamandla (i-GB / T 36276-2023) yakhululwa ekupheleni kukaDisemba 2023 kwaye iya kuphunyezwa ngoJulayi 1, 2024. Ngophuhliso olukhawulezayo lwemarike yokugcina amandla ebhetri ye-lithium-ion kwiminyaka yamuva nje, iingozi nazo bezisenzeka rhoqo. Ngokusekelwe kule nto, xa kuthelekiswa nenguqu ye-2018, isakhiwo esipheleleyo senguqu entsha sihlala singatshintshi, kodwa iimfuno zobugcisa zingqongqo, kwaye iimfuno zokuvavanya zibanzi.

Isakhiwo se-hierarchical yenkqubo yokugcina amandla ngolu hlobo lulandelayo: iiseli zixhunyiwe kwi-series kunye ne-parallel ukuze zenze imodyuli yeseli, iimodyuli zeeseli zixhunyiwe kwi-series kunye ne-parallel ukwenza i-cell cluster, i-cell cluster ixhunyiwe ngokufana ukwenza amandla ebhetri. inkqubo yokugcina, kunye neenkqubo zokugcina amandla ebhetri ziqhagamshelwe ngokunxuseneyo ukwenza isikhululo sokugcina amandla ebhetri. Ukusebenza kunye nokhuseleko lwenkqubo yebhetri ngundoqo wesiseko sokusebenza kwesikhululo sokugcina amandla. I-GB / T 36276-2023 ihlanganisa iiparitha eziphambili zokusebenza kunye nokhuseleko lokusebenza ukusuka kwinqanaba leeseli, iimodyuli ukuya kumaqela, kwaye ichaza ngokucacileyo iimfuno kwinqanaba ngalinye leebhetri.

Ngenxa yeengxaki zendawo, siya kubonisa utshintsho oluphambili phakathi kweenguqulelo ezintsha kunye nezindala kwiindawo ezimbini. Lo mbandela ugxininisa kwiinguqulelo eziphambili kwiiseli.

Isishwankathelo

Lilonke, inguqulelo entsha ye-GB/T 36276 ibone utshintsho oluninzi. Umzekelo:

• Ngokwenziwa komsebenzi, zonke iimfuno zesalathisi sokusebenza ziphakanyisiwe.
• Ukuhamba ngebhayisikili, ubushushu bomjikelezo butshintshiwe kwi-45 ° C ukunciphisa ixesha lokujikeleza.
• Kubaleka i-thermal, iye yatshintshwa ibe yi-dual-trigger ngokugqithiswa kunye nokufudumeza, kunye novavanyo lwe-thermal runaway emva kokuhamba ngebhayisikili yongezwe.
• Ukhuseleko, iimeko zokuvavanya nazo ziqinisiwe, iimfuno zokuchasana komgca we-short-circuit zihlanjululwe, kwaye i-extrusion force iye yanda.
• Ukuze iimveliso zisetyenziswe kwiindawo eziphakamileyo ngaphezu kwe-2000m, ukusebenza okongeziweyo kunye nokuvavanywa kokhuseleko lokuphakama kuyafuneka.

Iimfuno zovavanyo ezingqongqo zenza umngeni omkhulu kubavelisi. Abavelisi kufuneka baqonde ngokukhawuleza iimfuno zomgangatho omtsha kwaye benze utshintsho loyilo olujoliswe kuyo kwiimveliso zabo ukuqinisekisa uvavanyo olugudileyo kunye nokuthotyelwa.

Kwinyanga ezayo, siya kukutolikela utshintsho kwimodyuli yeseli kunye neengxenye zeqela leeseli ze-GB/T 36276-2023. Hla umamele!
