Ubujyakuzimu ni ubuhe?

Ubujyakuzimu bwo gusohora ni ijanisha ryubushobozi wakuye muri bateri. Niba utangiye byuzuye ukabigeza kuri 20%, ibyo ni 80% DoD. Biroroshye bihagije.

Impamvu umuntu wese yitaye kuriyi mibare ni ubuzima bwinzira. Datasheet ya bateri yose iguha igipimo cyizunguruka, ariko urwo rutonde ntacyo bivuze utazi DoD rwageragejwe kuri. Akagari kagizwe ninzinguzingo 4000 kuri 50% DoD irashobora kuguha gusa inzinguzingo 1200 niba uyikoresha ubusa buri gihe. Nabonye imishinga itwikwa nibi. Umuntu agaragaza sisitemu ishingiye kumutwe wumubare wumubare udasomye neza, kandi nyuma yimyaka ibiri ipaki irakomera.

Tradeoff Ntamuntu Wifuza Kuvuga

Dore ikintu. Shallow amagare yongerera ubuzima, ariko kandi bivuze ko uriha ubushobozi utigeze ukoresha. Sisitemu ya 100 kWh igarukira kuri 60% DoD iguha 60 kWh kuri buri cyiciro. Urashobora kugura paki ntoya ukayikoresha cyane. Niba ibyo byumvikana biterwa nigiciro cyakagari, ikiguzi cyo gusimbuza, imbogamizi zurubuga, hamwe nizindi mpinduka zigera kuri cumi nagatanu. Nta gisubizo kiboneye kuri bose.

LFP selile yahinduye imibare kuriyi. Imyaka itanu irashize, gukoresha NMC kugeza 90% DoD byasabye ibibazo. Uruhande rwa cathode ruratandukana. Gutakaza Oxygene, kwangirika kwimiterere, abantu bose basanzwe bakekwa. LFP ntabwo ifite ubwo buryo bwo kunanirwa kuri DoD yo hejuru. Urashobora kuyisunika cyane nta gihano kimwe. Niyo mpamvu imishinga myinshi yo kubika ihagaze yimukiye muri LFP nubwo ingufu zingana ari mbi.

Niki Mubyukuri Yica Utugari kuri High DoD

Uruhande rwa anode ruhangayikishwa kumpande zombi za reta yishyurwa. Hasi hafi ya zeru, urimo gukuramo lithium muri grafite ishaka rwose kuyifata. Igice cya SEI kiracika kandi kivugurura. Igihe cyose ivuguruye, irya lithium nyinshi kandi ubushobozi bukagabanuka. Hafi ya 100%, cyane cyane kumafaranga yihuse, ushobora guhura na plaque. Ntabwo bikabije ari byiza kuramba.

Kwangirika kwa Cathode biterwa cyane na chimie. NMC111 irahagaze neza kuruta NMC811 kuri voltage ndende, ariko NMC811 iguha ubwinshi bwingufu. Cathodes yo hejuru - nikel irashaka kurekura ogisijeni mugihe uyitandukanije nigihe runaka. Iyo ogisijeni ikora na electrolyte kandi ikabyara ubushyuhe. Komeza ukore ibyo kandi selile ishaje vuba.

Guhangayikishwa na mashini bifite akamaro kuruta uko abantu benshi babibona. Graphite irabyimba iyo uyitanze. Silicon anode irabyimba cyane. Amagare maremare asobanura impinduka nini nini, guhangayikishwa cyane na electrode, amahirwe menshi yo gusiba cyangwa guturika. Bimwe muri silicon nshya - kuvanga anode bifite ibibazo nyabyo nibi.

Uburyo Sisitemu Ikemura Imipaka ya DoD

Buri sisitemu yo gucunga bateri ifite min na max SoC. BMS ntizakwemerera kujya hanze yiryo dirishya. Ibyo umukiriya yita "0%" mubyerekanwe birashoboka ko 5% cyangwa 10% nyabyo SoC. Ibyo bita "100%" birashobora kuba 95%. Ababikora bakora ibi kugirango bubake.

Ingorabahizi nuko ubushobozi bugabanuka mugihe runaka. Akagari katangiye kuri 100 Ah gashobora kuba kuri 85 Ah nyuma yimyaka itatu. Niba BMS yawe igikoresha ubushobozi bwumwimerere agaciro, kubara kwa DoD ni bibi. Sisitemu nziza isubiramo buri gihe. Sisitemu ihendutse ntabwo.

Ubushyuhe butera ikindi cyuma. Akagari kuri dogere 0 gashobora gutanga 60% gusa yubushobozi bwacyo nubwo wagerageza gukuramo 100% DoD. Litiyumu ntishobora kugenda vuba bihagije. Sisitemu zimwe zitandukanya imipaka ya DoD mu buryo bwikora iyo hakonje. Abandi bakwemerera kugerageza ukananirwa.

Ibyo mbwira abakiriya

Kubika grid, 80% DoD nibisanzwe. Ubona gukoresha neza utishe selile. Amafaranga yinjira muri porogaramu akenera inzinguzingo nyinshi kumunsi arashobora kujya kuri 70% kugirango abungabunge ubuzima. Imbaraga zububiko zicaye ubusa umwanya munini zirashobora kugura 90% cyangwa irenga mugihe kidasanzwe gikenewe.

Ububiko bw'izuba butuye ni 80 - 90%. Tesla Powerwall ikora hafi 100% ikoreshwa, ariko bakoresha selile zabo hamwe nimibare yabo ya garanti. Abandi-baterankunga bakunda guhuza ibitekerezo.

EV ziri ku ikarita. Ibyerekanwe 0-100% kurubaho rwawe ntabwo bihuye nimbibi zifatika. Ababikora bahisha ubushobozi kumpande zombi. Ni bangahe biterwa nigishushanyo mbonera nuburyo garanti ya garanti iteye.

Umurongo wo hasi nuko DoD ihitamo igishushanyo, ntabwo ari umubare uhamye. Uhitamo ukurikije ubukungu, kwihanganira ingaruka, hamwe nibisabwa. Umuntu wese ukubwira ko hari igisubizo kimwe cyukuri kuri buri kibazo ntabwo yakoze imishinga ihagije.
