Ubuzima busanzwe bwisi bushingiye cyane kumikorere (ubushyuhe, kwishyuza protocole, gusohora ubujyakuzimu) kuruta imiterere yonyine.

Ese ingirabuzimafatizo zifite umutekano muke kuruta selile prismatic?

Umwirondoro wumutekano uratandukanye kuruta kurutonde. Ingirabuzimafatizo zirimo kunanirwa munzu zikomeye ariko zitanga umuvuduko mwinshi imbere mugihe cyumuriro - bishobora kuviramo guhumeka. Ingirabuzimafatizo zananirwa cyane kubyimba buhoro buhoro, zitanga umuburo ugaragara, ariko ibipfunyika byoroshye ntabwo bitanga uburinzi bwimbere. Sisitemu ikozwe neza igera kumutekano ugereranije utitaye kumiterere ukoresheje imicungire yubushyuhe ikwiye, igishushanyo mbonera, hamwe na sisitemu yo gucunga bateri.

Ni ukubera iki telefone zigendanwa zikoresha selile mu gihe EV zikunda prismatic?

Porogaramu yibanze itwara imiterere yo guhitamo. Terefone zigendanwa zorohereza byibura umubyimba nuburemere mubidukikije byubukanishi - ingirabuzimafatizo zuzuye muri ibi bipimo. Imodoka zamashanyarazi zishyira imbere ubuzima bwikizunguruka, ubushyuhe bwumuriro, hamwe nigihe kirekire cyo gukanika hejuru yo kuzigama uburemere buke {{3} cells selile prismatic zitanga serivisi nziza. Ariko, ibidasanzwe birahari: EV zimwe (zimwe na zimwe za Nissan Leaf variants) zikoresha neza ingirabuzimafatizo, mugihe terefone zigendanwa zishobora kwerekana utugingo ngengabuzima duto cyane kugirango twongere igihe kirekire.

Ni bangahe guhitamo imiterere ya bateri bigira ingaruka kubiciro rusange?

Guhitamo imiterere bigira ingaruka kuri 15 - 30% bya sisitemu ya bateri yose irenze amafaranga yakoreshejwe na selile. Prismatic selile igura 15-20% kurenza kilowatt-isaha ariko bisaba ibikoresho byubufasha bworoshye. Isakoshi ya selile ibika ikiguzi cya selile ariko isaba sisitemu zo guhunika hamwe nubuyobozi bwumuriro. Kurwego rwa sisitemu, itandukaniro ryibiciro rigabanuka kugera kuri 5-15% bitewe nubunini bwibicuruzwa nibisabwa nubushyuhe. Imikorere no kwizerwa bigira ingaruka kurenza ibiciro bitaziguye muguhitamo imiterere.

Ibyingenzi

Prismatic na pouch selile byerekana uburyo butandukanye bwo gupakirakuri lithium - ion chimie - igikonoshwa cyurukiramende rukomeye hamwe na laminates yoroheje - buriwese ahindura imikorere itandukanye aho guhagararira ikorana buhanga / rito.

Ingufu zingirakamaro zishyigikira ibishushanyo mbonera.

Ibyiza byo gucunga ubushyuhe nibyiza bya prismaticBinyuze mu cyuma gishushe cyo gukwirakwiza ubushyuhe, butuma imbaraga - zisohora ingufu mu gukoresha amamodoka n’inganda aho ingirabuzimafatizo zikenera uburyo bunoze bwo gukonjesha

Imiterere y'ibiciro iratandukanye: selile yamashanyarazi itanga 15 - 20% igiciro gito cyo gukora ariko isaba sisitemu nini - ishoramari murwego rwo gushyigikira imashini no gucunga amashyuza-ibiciro byose bya sisitemu bihurira muri 5-15% mubipimo

Ibisabwa bisabwa gutwara uburyo bwiza bwo guhitamomurwego rutandatu rwicyemezo: imiterere yimbaraga, ibidukikije byubukanishi, imbogamizi zumwanya, ingano yumusaruro, ubuzima bukenera ubuzima, hamwe namabwiriza yumutekano - nta format "nziza" isanzwe ibaho murwego rwo gukoresha
