1. Kumenyekanisha bateri ya lithium-ion
1.1 Leta ishinzwe (SOC)
Leta yishyurwa irashobora gusobanurwa nkuburyo ingufu zamashanyarazi ziboneka muri bateri, ubusanzwe zigaragazwa nkijanisha.Kuberako ingufu z'amashanyarazi ziboneka zitandukanye hamwe no kwishyuza no gusohora ibintu, ubushyuhe hamwe nubusaza, ibisobanuro bya leta yishyurwa nabyo bigabanijwe mubwoko bubiri: Absolute State-Of-Charge (ASOC) na Reta-ya-ishinzwe (RSOC) .
Mubisanzwe, intera ya reta yishyurwa ni 0% - 100%, mugihe ari 100% mugihe bateri yuzuye kandi 0% mugihe irangiye.Imiterere yuzuye yishyurwa nigiciro cyerekanwe kibarwa ukurikije igiciro cyagenwe cyagenwe cyagenwe mugihe bateri yakozwe.Imiterere yuzuye ya bateri nshya yuzuye yuzuye ni 100%;Nubwo bateri ishaje yashizwemo byuzuye, ntishobora kugera 100% mugihe cyo kwishyuza no gusohora ibintu bitandukanye.
Igishushanyo gikurikira cyerekana isano iri hagati ya voltage nubushobozi bwa bateri kubiciro bitandukanye byo gusohora.Iyo igipimo cyo gusohora kiri hejuru, nubushobozi bwa bateri.Iyo ubushyuhe buri hasi, ubushobozi bwa bateri nabwo buzagabanuka.
Igicapo 1. Isano iri hagati ya voltage nubushobozi mubipimo bitandukanye byo gusohora nubushyuhe
1.2 Umuvuduko mwinshi wo kwishyuza
Umuvuduko mwinshi wumuriro ujyanye nibigize imiti nibiranga bateri.Amashanyarazi yumuriro wa batiri ya lithium mubisanzwe ni 4.2V na 4.35V, kandi agaciro ka voltage ya cathode nibikoresho bya anode bizatandukana.
1.3
Iyo itandukaniro riri hagati yumubyigano wa bateri na voltage ntarengwa yo kwishyuza iri munsi ya 100mV naho amashanyarazi yo kugabanuka akagabanuka kuri C / 10, bateri irashobora gufatwa nkumuriro wuzuye.Imiterere yuzuye yo kwishyuza iratandukanye nibiranga bateri.
Igishushanyo gikurikira kirerekana bateri isanzwe ya lithium yishyuza iranga umurongo.Iyo ingufu za bateri zingana na voltage ntarengwa yo kwishyuza hanyuma amashanyarazi akagabanuka kugeza kuri C / 10, bateri ifatwa nkumuriro wuzuye
Igishushanyo 2. Batiri ya Litiyumu yishyuza iranga umurongo
1.4 Umuvuduko ntarengwa wo gusohora
Umuvuduko ntarengwa wo gusohora urashobora gusobanurwa nogukata-gusohora voltage, ubusanzwe ni voltage mugihe leta yishyuye ari 0%.Agaciro ka voltage ntabwo ari agaciro gahamye, ariko ihinduka hamwe nuburemere, ubushyuhe, gusaza cyangwa izindi mpamvu.
1.5 Gusohora byuzuye
Iyo ingufu za bateri ziri munsi cyangwa zingana na voltage ntoya, birashobora kwitwa gusohora byuzuye.
1.6 Igipimo cyo kwishyuza no gusohora (C-Igipimo)
Igipimo cyo kwishyuza-gusohora nikigereranyo cyumuriro-usohora ugereranije nubushobozi bwa bateri.Kurugero, niba ukoresheje 1C kugirango usohore isaha imwe, nibyiza, bateri izasohoka burundu.Ibiciro bitandukanye-bisohoka bizavamo ubushobozi butandukanye bukoreshwa.Mubisanzwe, urwego rwo hejuru rwo kwishyuza-gusohora, nubushobozi buke buboneka.
1.7 Ubuzima bwinzira
Umubare wizunguruka bivuga umubare wamafaranga yuzuye no gusohora bateri, ushobora kugereranywa nubushobozi bwo gusohora nubushobozi bwo gushushanya.Iyo ubushobozi bwo gusohora bwuzuye bungana nubushobozi bwo gushushanya, umubare wizunguruka ugomba kuba umwe.Mubisanzwe, nyuma yincuro 500 zokwirukana-gusohora, ubushobozi bwa bateri yuzuye yuzuye izagabanuka 10% ~ 20%.
Igicapo 3. Isano iri hagati yigihe cyizuba nubushobozi bwa bateri
1.8 Kwirekura
Kwisohora kwa bateri zose biziyongera hamwe no kwiyongera kwubushyuhe.Kwisohora ubwabyo ntabwo ari inenge yo gukora, ahubwo biranga bateri ubwayo.Ariko, kuvura bidakwiye mubikorwa byo gukora nabyo bizatera kwiyongera kwikuramo.Mubisanzwe, igipimo cyo kwikuramo kizikuba kabiri mugihe ubushyuhe bwa bateri bwiyongereyeho 10 ° C. Ubushobozi bwo kwisohora bwa bateri ya lithium-ion bugera kuri 1-2% buri kwezi, mugihe iyindi bateri zitandukanye zishingiye kuri nikel ari 10- 15% buri kwezi.
Igicapo 4. Imikorere yikigereranyo cyo kwisohora cya batiri ya lithium mubushyuhe butandukanye
