Batiri ya Litiyumubivugwa ko bitoroshye, mubyukuri, ntabwo bigoye cyane, byavuzwe byoroshye, mubyukuri, ntabwo byoroshye.Niba ukora muriyi nganda, birakenewe rero kumenya amwe mumagambo asanzwe akoreshwa munganda za batiri ya lithium, muricyo gihe, ni ayahe magambo asanzwe akoreshwa munganda za batiri ya lithium?
Amagambo asanzwe akoreshwa mubikorwa bya batiri ya lithium
1.Ibiciro-Igiciro / Gusohora-Igipimo
Yerekana uburyo bugezweho bwo kwishyuza no gusohora, mubisanzwe ubarwa nkububasha bwububasha bwa nomero ya bateri, mubisanzwe byitwa C. Nka bateri ifite ubushobozi bwa 1500mAh, hateganijwe ko 1C = 1500mAh, iyo isohotse hamwe 2C nayo isohoka hamwe numuyoboro wa 3000mA, 0.1C yishyurwa kandi isohoka irishyurwa kandi ikarekurwa na 150mA.
2.OCV: Gufungura umuyaga wumuzunguruko
Umuvuduko wa bateri muri rusange werekana kuri voltage nominal (nanone yitwa voltage yagenwe) ya batiri ya lithium.Umuvuduko w'izina wa bateri isanzwe ya lithium ni 3.7V, kandi twita na voltage yayo ya 3.7V.Kuri voltage muri rusange tuvuga kuri voltage yumuzunguruko wa batiri.
Iyo bateri ifite 20 ~ 80% yubushobozi, voltage iba yibanze kuri 3.7V (hafi 3.6 ~ 3.9V), hejuru cyane cyangwa ubushobozi buke cyane, voltage iratandukanye cyane.
3.Ingufu / Imbaraga
Ingufu (E) bateri ishobora kuzimya iyo isohotse kurwego runaka, muri Wh (amasaha ya watt) cyangwa KWh (amasaha ya kilowatt), hiyongereyeho 1 KWh = 1 kWh y'amashanyarazi.
Igitekerezo cyibanze kiboneka mubitabo bya fiziki, E = U * I * t, nabyo bingana na voltage ya bateri igwijwe nubushobozi bwa bateri.
Kandi formulaire yimbaraga ni, P = U * I = E / t, yerekana ingano yingufu zishobora kurekurwa mugice cyigihe.Igice ni W (watt) cyangwa KW (kilowatt).
Batare ifite ubushobozi bwa mAh 1500, kurugero, ifite voltage nominal ya 3.7V, bityo ingufu zihuye ni 5.55Wh.
4. Kurwanya
Nkuko kwishyuza no gusohora bidashobora kugereranywa no gutanga amashanyarazi meza, hariho ukurwanya imbere.Kurwanya imbere bitwara imbaraga kandi birumvikana ko bito bito birwanya imbere.
Kurwanya imbere kwa bateri gupimwa muri miliohms (mΩ).
Imbere yimbere ya bateri rusange igizwe na ohmic imbere yo kurwanya imbere hamwe na polarisiyasi yimbere.Ingano yo kurwanya imbere imbere iterwa nibikoresho bya bateri, inzira yo gukora, ndetse n'imiterere ya bateri.
5.Ubuzima
Kwishyuza Bateri no gusohora rimwe byitwa cycle, ubuzima bwikizamini nikimenyetso cyingenzi cyimikorere ya bateri.Igipimo cya IEC giteganya ko kuri bateri ya terefone igendanwa ya litiro, 0.2C isohoka kuri 3.0V na 1C ikishyura kuri 4.2 V. Nyuma y’inshuro 500 inshuro nyinshi, ubushobozi bwa batiri bugomba kuguma hejuru ya 60% yubushobozi bwambere.Muyandi magambo, ubuzima bwa cycle ya batiri ya lithium ni inshuro 500.
Igipimo cy’igihugu giteganya ko nyuma yizunguruka 300, ubushobozi bugomba kuguma kuri 70% yubushobozi bwambere.Batteri ifite ubushobozi buri munsi ya 60% yubushobozi bwambere igomba gusuzumwa muri rusange.
6.DOD: Ubujyakuzimu
Byasobanuwe nkijanisha ryubushobozi bwasohotse muri bateri nkijanisha ryubushobozi bwagenwe.Byimbitse gusohora bateri ya lithium muri rusange, igihe gito cya bateri.
7.Gabanya amashanyarazi
Umuvuduko w'amashanyarazi ugabanijwemo kwishyuza voltage yo kurangiza no gusohora voltage yo kurangiza, bivuze ko imbaraga za bateri idashobora kwishyurwa cyangwa gusohora kure.Amashanyarazi yo guhagarika amashanyarazi ya batiri ya lithium muri rusange ni 4.2V naho voltage yo gusohora ni 3.0V.Birabujijwe kwishyuza cyane cyangwa gusohora bateri ya lithium irenze voltage yo guhagarika.
8.Gusezerera
Yerekeza ku gipimo cyo kugabanuka kwubushobozi bwa bateri mugihe cyo kubika, byagaragajwe nkigabanuka ryijanisha ryibirimo kuri buri gice cyigihe.Igipimo cyo kwisohora cya batiri isanzwe ya lithium ni 2% kugeza 9% / ukwezi.
9.SOC (Leta ishinzwe)
Yerekeza ku ijanisha ryamafaranga asigaye ya bateri kumafaranga yose ashobora gusohoka, 0 kugeza 100%.Yerekana amafaranga asigaye ya bateri.
10.Ubushobozi
Yerekeza ku mbaraga zishobora kuboneka muri litiro ya batiri mugihe runaka cyo gusohora.
Inzira y'amashanyarazi ni Q = I * t muri coulombs kandi igice cyubushobozi bwa bateri cyerekanwe nka Ah (amasaha ampere) cyangwa mAh (amasaha ya milliampere).Bivuze ko bateri ya 1AH ishobora gusohoka mumasaha 1 hamwe numuyoboro wa 1A mugihe byuzuye.
