Ubushuhe bwo Gukoresha Ni Ibiki?

Ni idirisha ry’ubushuhe aho litiyumu - iyo mu vy’ukuri yemerewe gushaja no gusohoka ata BMS itera umugera canke ingingo zica zica mu gacerere. Ibiharuro ubona kuri benshi mu baguzi-barle 18650/21700 urutonde rw'amakuru (ikaduze –20℃megrade 60 , usaba 0 degre 4 digre 45 ) si ibinyoma, ariko ni imibare "y'isoko". Ubuzima nyabwo ni bwo burusha.

Nakuyeho ububasha buhagije bwihishije-buto amapaki n'amabateri y'amazi n'amabateri e- kugira ngo menye: urupapuro rw'amakuru ni vyo vyiyumviro, imva ni umugenzo.

Ubushuhe bwo kubika ni bwo gace kashobora kurokoka mu gihe ataco rikora. Ushobora gusiga akazu keza ka NMC kuri –40℃mu mwaka kandi bizoba vyiza iyo ubishushe. Ubushuhe bwo gukoresha ni igihe umuriro uriko uratemba. Aho niho mu vy’ukuri ubuhinga bwa shimi butegerezwa kuba imbere muri jellyroll, kandi ubuhinga bwa shimi ni diva ku bushuhe.

Igiharuro kiri musi ya 0 degre 0 kandi uriko urashira icuma ca litiyumu ku anode - bishobora gusubirana, ubushobozi- Gukora, kandi rimwe na rimwe uratera imbere iyo amadendrite akura. Kwirukana kuri –30 degre ? Ico gice ntikizopfa, kizoca gusa: amataratara y’umuriro nk’amasazi nk’ayasazi, y’imbere, kandi ushobora kumbure 60–70 % y’ubushobozi. Mukare n’ubundi kandi birahimbarwa. Nta kibi kigumaho.

99 % vy’ingingo z’abaguzi: 0℃gushika kuri 45 degre , rimwe na rimwe 0–60℃iyo uwubikora ariko yumva ubutwari. Ikintu cose gikanye → litiyumu. Igiharuro cose ca BMS kiragabanya umuriro ku rugero rwo hejuru 0–2℃. Hariho amapaki y’abashinwa y’abashinwa ataco akora, kandi ni co gituma ubona amabateri menshi cane apfutse - Amabateri mu bibanza vy’uguhagarara kw’i Harbin buri mpera y’umwaka.

Hariho ibidasanzwe, birashoboka:

Gusukura, Tadiran, canke utugingo ngengabuzima tw’indege dufise ama electrolytes y’ibintu vy’agaciro bishobora kwicara kuri –20℃, ariko uriha mu zuru.

LTO (litiyumu titanate) iratwenga – 30 degrés yihuta. Down iruhande? Ica kabiri c’inguvu n’igiciro incuro zibiri. Uca ugaragaza LTO gusa nimba uriko urakora bisi za Siberia canke vyihuta- ibibanza vyo muri Norvege.

Igitigiri c’amazi co hejuru ni co gikunda kuba 45℃kuko hejuru y’aho, ukukura kwa SEI n’ugubora kw’umuyagankuba biragenda. Suzuma akazu ka NMC811 ku 55 degrees buri musi kandi uzobona ko rigabanuka kuri 80 % SOH mu mezi atatu aho kumara imyaka itatu.

Operating Temperature

Utugingo ngengabuzima twinshi turaboneka –20 kugeza ku 60 degre 60 , hariho degre imwe –30 ubu. Ibara gusa rituma utugingo ngengabuzima tugira ubunebwe (IR irengeye, umuriro wo hasi munsi y’umuzigo, ubushobozi buke bwo gukoresha). Ubushuhe buratuma bigenda vyihuta, ariko igice kimwe c'ideni 70 c'ideni ntikizoca kigica - ibice vy'ipulasitike bishobora, naho.

LFP ni umwami w’ubushuhe. Nabonye ama module ya CATL akora akora 65℃ataco amenagura icuya. NMC/NCA muri ubwo bushuhe? Abayitandukanya batangura kugabanuka kandi uri umusi umwe mubi ku bijanye no gutera umwuka.

Uzosanga utugingo ngengabuzima twirata "–40℃gushika ku 85 degree." Birahari. Ivy’igisirikare, amavuta na gazi, n’abahinguzi bamwebamwe ba EV barabigura. Ico ako gatabu kadasemerera: 20–30 % y’uburemere bw’inguvu, 2–4× igiciro, kandi kenshi n’ubuzima bw’ingendo bugabanya ubuzima kubera ko umuyagankuba wuzuye ibintu bitangaje. Uriha urutonde, uratakaza ibindi vyose. Bikoreshe gusa iyo drone itegerezwa gutangura kuri – 35℃muri Alaska canke igihe satellite yawe idashobora gutanga igikoresho co gushusha.

Shira isandugu yirabura y’izuba ry’i Texas ku 38℃→ cellule recekale igera kuri 65 degree. Ivyiza - Ipaki 300 kW mu ci → ΔT ku 25 degre 25 mu minota cumi mbere n’ugukonjesha kw’amazi. Siga ipikipiki hanze muri –15℃mu rushana ijoro → ubushuhe nyamukuru ni –13℃ku gitondo, kandi oya, BMS ntizogureka ngo wisonzeshe- Gushushanya gushika igikoresho co gushusha kivyuka.

Tesla, BYD, mu vy’ukuri umuntu wese afise umutima ukunze, ashushanya iyo pack iri mu nzira ija ku gikombe ca Supercharger mu rushana, aca akuraho ububasha mu ci. Igitigiri cawe ca AliExpress e{-scooter? Amahigwe masa.

Operating Temperature

Ubuhinga	Igiciro gisanzwe	Gusohoka mu mubiri	Ivyiyumviro
NMC / NCA	0–45 degree	–20–60 degree	Inguvu nyinshi, umwamikazi w'ubushuhe
LFP	0–60℃(bimwe 65)	–20–65 degree	Indwara n’umutekano, yanka ububasha bukomeye
LTO	–30–55 degree	–40–65 degree	Amakarita aho hose, abika igice c'inguvu .
"Icigwa ca Military"	–40–85 degree	–40–85 degree	Kuba ari ko biri, birababaza sasita .

Umurongo w'abantu: ufate imipaka y'urutonde rw'amakuru nk'amategeko akomeye yo gushaja, amabwirizwa yoroshe yo gukuraho, n'ibinyoma vy'ukuri ku "ivyo mu vy'ukuri bishika mu mashamba."

Gumana ipaki yawe iri hagati ya 15–35℃uko bishoboka kwose kandi izogukunda mu bihe igihumbi. Ibindi vyose ni ukugenzura ivyonona.
