Ikigereranyo cya Leta yubuzima (SOH)
SOH ya bateri nayo irashobora kugaragazwa nkigihe cyayo. Igihe cya bateri gishobora kugabanywamo ubwoko bubiri bushingiye kumikoreshereze itandukanye: igihe cyo kubika nigihe cyo kubaho.
Ubuzima bwo kubika bugaragaza gusaza nibisubizo bya bateri mugihe cyo kubika. Mugihe cyo kubika, ubushobozi bwa bateri buragabanuka kuburyo budasubirwaho, kandi igipimo cyo gusohora - kiratandukanye cyane bitewe nububiko. Kubwibyo, kwihuta cyangwa kwihuta kwa bateri yo gusaza biterwa nububiko. Ubushyuhe bwo kubika nikintu gikomeye kigira ingaruka kumara igihe cyo kubika no kwikorera - gusohora. Ugereranije n'ubushyuhe bwo mucyumba, ubushyuhe bwo kubika bateri burenze butera reaction kuruhande (nka ruswa), kandi gutakaza ibyuma bya casi birakabije; mugihe ku bushyuhe buke, ikwirakwizwa ryibintu hamwe n’amashanyarazi bigabanuka, bityo bikagabanya umuvuduko wa batiri. Ikindi kintu kigira ingaruka kububiko bwa bateri igihe cyose ni agaciro ka SOC mugihe cyo kubika bateri (hano, SOC isobanurwa nkigipimo cya ion kuri electrode). Ku bushyuhe bumwe bwo kubika ariko ububiko butandukanye bwa SOCs, inzira yo gusaza ya bateri iratandukanye. Kuri SOCs ndende, ubusumbane bunini bubaho kuri interineti ya electrode / electrolyte, iteza imbere amashanyarazi.
Ubuzima bwa cycle bwerekana ingaruka zo gukoresha bateri (kwishyuza no gusohora) kuri bateri. Gusaza kwa bateri bibaho ubudahwema mugihe cyo kwishyuza no gusohora. Ubushyuhe nubu mugihe cyo gukoresha bateri bigira ingaruka mubuzima bwikizunguruka. Byongeye kandi, ibintu bigira ingaruka kubuzima bwa bateri nabyo bigira ingaruka mubuzima bwizunguruka, nkuko reaction zifitanye isano zititaye niba bateri ikoreshwa cyangwa iruhutse. Gukoresha Bateri ni inzira idasanzwe; ubushyuhe bwiyongereye bwihutisha ibyo bitekerezo, bityo byihuta gusaza kwa batiri. Usibye izi mpinduka, ibipimo bijyanye nubuzima bwinzira ni imikorere ya bateri yumuriro. Umubare w'amafaranga yatakaye mugihe cyo gusohora rimwe (guhinduka muburyo bwo kwishyurwa) nikintu gikomeye gifite ingaruka zikomeye kubusaza bwa batiri. Iyi phenomenon ahanini iterwa no kwangirika kwa electrode nziza no gushiraho firime ya SEI mugihe kinini - kwishyuza no gusohora.
1. Ibisobanuro bya Leta yangiza (SOH) muri Batteri
Ibisobanuro bitandukanye bya SOH birashobora gukomoka mubitekerezo bitandukanye. Kugeza ubu, ubusanzwe bukoreshwa mubushakashatsi bwa bateri burimo ubusobanuro bwimbere bwimbere, ubujyakuzimu bwibisobanuro bisohoka, hamwe nubusobanuro bwamafaranga asigaye.
(1) Uburyo bwo Kurwanya Imbere Uburyo bwo Gusobanura
Imiterere ya bateri yubuzima igenda yangirika uko irwanya imbere ryiyongera buhoro buhoro. Imiterere yubuzima bwa bateri (SOH) irashobora gusobanurwa ukurikije iyi sano:
Muri formula, RNEW igereranya bateri imbere mugihe cyo gukora; REOL yerekana kwihanganira imbere kurangiza igihe cya bateri; na R byerekana bateri yimbere imbere muburyo bwubu.
Urufunguzo rwiki gisobanuro ni ukubona agaciro nyako kuri bateri imbere. Ibyiza byayo nibisubizo byukuri byo gupimwa, ariko ibibi byayo nuko itita kubushobozi bwa bateri yagenwe, ibyo bikaba bigira ingaruka cyane kubuzima bwa bateri (SOH).
(2) Ibisobanuro byimbitse yo gusohora (SOH)
Ubujyakuzimu bwo gusohora (SOH) bwa bateri bivuga igipimo cyubushobozi bwasohowe na bateri nubushobozi bwayo. Iri gereranya rihwanye ninshuro inshuro bateri ishobora kwishyurwa; ni ukuvuga, uko ubujyakuzimu bugenda busohoka, ni inshuro inshuro zishobora kwishyurwa. Kubwibyo, SOH irashobora gusobanurwa ukurikije ubujyakuzimu bwo gusohora nka: ijanisha ryumubare usigaye wa remarge kugeza ku mubare ntarengwa wo kwishyurwa ku bujyakuzimu bwatanzwe.
(3) Ibisobanuro byubushobozi busigaye
Leta ishinzwe (SOH) isobanurwa ukurikije ubushobozi busigaye bwa bateri. Nyuma yigihe cyo gukoresha, ubushobozi busigaye bwa bateri burashobora gupimwa neza. Noneho rero, reka Cnew ibe ubushobozi ntarengwa bwa bateri iyo idakoreshejwe, na Cnorm ibe ubushobozi bukoreshwa bwa bateri. Noneho, SOH irashobora gusobanurwa nk ...
