Ni igiki ciza: Ibarabara ry’i Litiyumu canke Ibanga ry’Ubushobozi buhambaye?
Umuntu mu mugwi wacu w’abagurisha yaranrungikiye iki kibazo c’ugushakashaka mu ndwi iheze. Abarongozi b’amasoko baraguma babibaza, rero biboneka ko dukeneye kuvyishura ataco bimaze.
"Litiyumu" ni ubuhinga bwa shimi. "Ubushobozi bwinshi" ni ubunini. Bateri ishobora kuba - kinini cane ni. Ariko ndazi igituma iki kibazo kiguma kiduga. Uriko uraba amajambo, umwe avuga ko "litiyumu 500Ah" ku madolari 15.000, uwundi avuga "ubushobozi bwinshi 1000Ah" ku madolari 8.000. Ica kabiri kimeze nk’ibateri incuro zibiri ku giciro c’igiciro.
Si uko biri. Niwagura ushingiye kuri iyo nzira, uzomenya igituma mu mezi nka 8 igihe uriko uragura abazogusubirira.
Umubare w'ubushobozi ku Label
Naciye nicara mu makoraniro menshi cane aho umuntu akura urupapuro rw’ibara ry’agahama maze akavuga ku rugero rwa Ah nk’aho yoba ari we ashiraho iyo mpari.
Umurongo - ntashobora gutanga ubushobozi bwo gutanga amakuru ataco usenyemeza . 50% uburebure bw'ibisohoka ni igipimo c'ibikorwa nimba ushaka ubuzima bubereye. 1000Ah umurongo w'imbere-iri package iguha 500Ah. LFP ikora 80-90% DOD isanzwe-a 500Ah itanga 400-450Ah ku musi mu myaka 8-10.
Twarasubiyemwo ububiko bw’ibicuruzwa vyakonje muri Guangdong umwaka uheze. 800Ah uburongozi bw’ibikamyo, amasaha 3 yo gukora ku -18℃imbere y’uko duhindura. Twarashize muri 600Ah LFP n’ubushuhe bw’ubushuhe{6}} amasaha. Amakamyo nyene, inzira nyene. Iryo zina ryagabanutse 25%, inguvu nyazo zishobora gukoreshwa hafi incuro zibiri.
Ibara rituma rirushiriza kuba ribi. Ishirahamwe ry’ubuhinga bwa none (cbea.com) ryagerageje iki -LFP ifise ubushobozi 67% ku -20℃, imbere y’igihe - iragabanuka kugera kuri 40-50%. Tangurira ko hejuru y'urugero rw'ugusohoka n'umurongo wawe "ubushobozi bwinshi" ni ukuguha 20-25% vy'ivyo ikimenyetso kivuga.
Iyindi nzira y'ubushobozi
Ivyuma bibiri vy’ivyuma, akarorero kamwe, ubushobozi bumwe. Murazigerageza. Pack A ingero 660mAh. Pack B ipima 605mAh.
Barungike mu nzinguzingu 50-100. Pack A igabanuka kuri 580mAh, igwa. Pack B ifise 590mAh.
Pack A yari ifise ibintu vy’inyongera vy’ubuhinga bwa electrode bituma haba imibare y’intango ariko igatera imbere mu gushika ku ntumbero y’igihe kirekire. Imyimenyerezo isanzwe, cane cane ku baguzi bahiganwa ku giciro.
Uko wobifata:
gusaba amakuru y’ubuzima bw’ingendo ku burebure bw’ugusohoka kwawe, si ayabo. Basubiramwo inzinguzingu 3000 ku 50% DOD. Ukoresha 80% ku musi. None iyo nomero ni iyihe?
Igiharuro kimwe kivuye mu injeniyeri muri Shenzhen- inyuma y’imyaka 2, uguhinduka kw’umuriro kw’ingingo ngenderwako gukwiye kuguma munsi ya 30mV. Ububisha kuruta ivyo busobanura uguhuza kw’ingingo mbi canke uguhuza kwa BMS zidakwiye.
LFP vs NMC vs LTO
NMC ifise uburemere bwinshi bw'inguvu. 150-250 Wh/kg n'i 90-160 ku LFP.
LFP (Ifoto ya Litiyo)
Urutonde rw'ubushuhe:~270 degree
Ubuzima bwa Cycle:2000-4000
NMC (Nickel Manganese Cobalt)
Urutonde rw'ubushuhe:~210 degree
Ubuzima bwa Cycle:1000-1500
Ico kinogo 60- ni co gituma abahinguzi b’ibikoresho vy’ubuhinga bwa none b’Abadagi bava muri NMC. Isesengura rimwe rivuye kuri gabelstapler - mitmittendorf.com-NMC ifise ingorane zo guturika ku bijanye no kwinjira canke gushuha cane iyo LFP idafise. Ubuzima bw’ingendo bwa NMC bumara 1000-1500. LFP ikora 2000-4000.
LTO ni iyo gusumba . 10,000+, igura mu minota 10, ikora ku -40℃. Komatsu na Toyota L&F barayikoresha mu Buyapani kugira ngo babe uruhererekane rw’ubukonje. Ariko amadolari 150-200/kWh n’amadolari 70-100 ku LFP. Gusa birafise insiguro nimba gufata umwanya wo guhagarara ataremewe.
Ku 90% vy’ibikorwa vy’imbere: LFP. Nimba umuntu asunika NMC kugira ngo akore ivy’umubiri, nimubaze igituma.
Igice c'Amahera
LFP ntiyihenda imbere y'imbere. 48V ikoresheje amadolari 14.000-18.000. Abarongozi ni amadolari 6.000-9.000.
Ariko multi- imbere y'igihe-iri busobanura 3 ku kamyo. Ivyo ni amadolari 18.000-27.000 y’amabateri, hamwe n’icumba c’amabateri, umwuka, gutera imbere, guhindura ibikorwa.
LFP: bateri imwe. Igiciro c’akaryo mu gihe c’akaruhuko. Nta bikorwa remezo vyo guhindura.
Inyishu: amezi 18-28.
Texas 3PL, 50- Inyuma y'ubwato-$2.9 miliyoni mu myaka 8, kwishura ku kwezi kwa 31 (roork.com). Intsinzi nini ntiyari inguvu. Yari ikuraho iminota 15-20 ku guhindura.
Ingurube z'umutuku
Nta nyandiko z’inkomoko y’ingingo.
Iyo bitazokubwira aho utugingo ngengabuzima tuva, wiyumvire ko udashaka ko umenya.
BMS sples sples zitamenyekana.
Ivyinshi mu vyo kunanirwa- igice. Niba badashobora gusigura igenzura ry'ingingo, rikaba ry'urugero, uburinzi bw'ubushuhe, uburinzi buke bw'ivyuma{3}} gerageza tecceur - baguze iyo ihendutse kuruta izindi.
Igaranti ikuraho ikibazo cawe co gukoresha.
Ububiko bw’amabuye? Gushariza neza? Soma ivyo gukuraho. Nabonye garantiya iri munsi ya 0℃. Mu bikorwa vy’uruzitiro rukanye.
Ubushobozi bwashizwe kuri C/20 igihe uriko urakura C/5.
100Ah ku rugero rwa 5-amp ntibisigura 100Ah ku nshuro y’amano 20. Bishobora kuba 80Ah canke bike.
Guhuza
- Ububiko bw'ibintu, vyinshi- shift: LFP, ubunini bw'ugupfuka n'ibice 15-20%.
- Ububiko bukonje: LFP ifise ugushushanya, IP67. BMS itegerezwa kuba ifise - gerageza fura dosiye- Guca munsi ya 0℃bituma haba litiyumu ihoraho.
- 24/7 ata madirisha yo gushaja: LTO iyo ingengo y’imari iremeza.
- Inyuma/guhagarara munsi ya 100 -150 inzira/umwaka: Abarongozi bashobora gukora iyo umwanya udabujijwe.
Inyishu
Ku ngandaibikoresho vyo gukoresha mu gukoresha amashimwe menshi-LFP, ubunini bw'ibikorwa vyawe. Si kubera ko ari ivy’agaciro. Ubutunzi bw’ubuzima bw’ubuzima ubu burakunda cane.
CATL na BYD bafise ibice birenga 55% vy’uguhingura amabateri ya litiyumu kw’isi yose. LFP ni igice c’iterambere (SNE Ubushakashatsi biciye kuri cinevpost.com, 2024). Uburongozi bw'abajakubagira. Ntaco bimaze.
Niba ukiriko ugura imbere-ba ku bikoresho vy’agaciro kanini- ibikoresho vyo guhindura, uba uriko urakora neza ku nomero mbi.
Ibibazo vyihariye ku ruzitiro rw'ubukonje, hejuru-inga, canke guhuza ibiharuro- twebwe dushobora gukoresha imibare n'ibipimo vyawe.
