Chabwino n'chiti: Battery Lithium kapena High Capacity Battery?
Wina m'gulu lathu lamalonda adanditumizira funsoli sabata yatha. Oyang'anira zogula amapitiliza kufunsa, kotero zikuwoneka kuti tikuyenera kuthana nazo mwachindunji.
"Lithium" ndi chemistry. "Mkulu mphamvu" ndi kukula. Batire likhoza kukhala zonse-zambiri mwa zabwino ndi. Koma ndikudziwa chifukwa chake funsoli likupitilira. Mukuyang'ana zolemba, wina akuti "lithium 500Ah" pa $ 15,000, wina akuti "kuchuluka kwa 1000Ah" pa $ 8,000. Yachiwiri ikuwoneka ngati batire kawiri pa theka la mtengo.
Si. Ngati mumagula kutengera malingaliro amenewo, mupeza chifukwa chake pafupifupi miyezi 8 mukamagula zosintha.
Nambala ya Mphamvu pa Label
Ndakhala m'misonkhano yambiri pomwe wina amakoka pepala ndikulozera pa Ah ngati amathetsa mkangano.
Lead{{0}asidiyo sangathe kupereka kuchuluka kwake popanda kudziwononga yekha. 50% kuya kwake ndi malire ake ngati mukufuna moyo wabwino. Phukusi lanu la 1000Ah lead{{4}acid limakupatsani 500Ah. LFP imayendetsa 80-90% DOD nthawi zonse-paketi ya 500Ah imapereka 400-450Ah tsiku lililonse kwa zaka 8-10.
Tinaonjezeranso nyumba yosungiramo zinthu zoziziritsa kukhosi ku Guangdong chaka chatha. 800Ah lead-acid pamalori ofikira, maola 3 akuthamanga pa -18 digirii tisanasinthe. Timayika 600Ah LFP ndi kutentha. 6.5 maola. Magalimoto omwewo, njira zomwezo. Dzinali linatsika ndi 25%, mphamvu zenizeni zogwiritsidwa ntchito pafupifupi kuwirikiza kawiri.
Kuzizira kumaipitsa. China Battery Industry Association (cbea.com) idayesa izi-LFP imakhala ndi mphamvu 67% pa -20 degrees , lead-acid imatsika kufika 40-50%. Ikani izo pamwamba pa malire otulutsa ndi asidi "wapamwamba" wa lead-acid akukupatsani 20-25% ya zomwe chizindikirocho chikunena.
The Other Capacity Trap
Mapaketi awiri a lithiamu, chitsanzo chomwecho, mphamvu zofanana. Inu muwayese iwo. Phukusi A ndi 660mAh. Phukusi B ndi 605mAh.
Kuthamanga iwo kwa 50-100 mkombero. Paketi A imatsikira ku 580mAh ndikugwa. Paketi B imakhala ndi 590mAh.
Paketi A inali ndi zowonjezera maelekitirodi zomwe zimathandizira manambala oyamba koma osakhazikika-kwanthawi yayitali. Zochita wamba, makamaka kuchokera kwa ogulitsa akupikisana pamtengo.
Momwe mungagwire:
funsani zambiri za moyo wanu pakuya kwanu kwenikweni, osati kwawo. Amatchula maulendo a 3000 pa 50% DOD. Mukugwiritsa ntchito 80% tsiku lililonse. Nanga nambala ndi chiyani?
Metric imodzi yochokera kwa injiniya wa ku Shenzhen-padutsa zaka 2, kusiyana kwa magetsi a ma cell kuyenera kukhala kosachepera 30mV. Kutalikirapo kumatanthawuza kusalinganiza bwino kwa ma cell kapena kusakwanira bwino kwa BMS.
LFP vs NMC vs LTO
NMC ili ndi mphamvu zochulukirapo. 150-250 Wh/kg poyerekeza ndi 90-160 pa LFP.
LFP (Lithium Iron Phosphate)
Thermal Runaway:~ 270 digiri
Moyo Wozungulira:2000-4000
NMC (Nickel Manganese Cobalt)
Thermal Runaway:~ 210 digiri
Moyo Wozungulira:1000-1500
Kusiyana kwa digirii 60-ndi chifukwa chake opanga ma forklift aku Germany adachoka ku NMC. Kuwunika kumodzi kochokera ku ma cell a gabelstapler-mittendorf.com-NMC ali ndi chiopsezo chophulika pakulowa kapena kutenthedwa kwambiri komwe LFP ilibe. Moyo wozungulira wa NMC umayenda 1000-1500. LFP imapanga 2000-4000.
LTO ndiyosiyanako. 10,{1}} mikombero, imalipira pakadutsa mphindi 10, imagwira ntchito mpaka -40 degrees . Komatsu ndi Toyota L&F amazigwiritsa ntchito ku Japan pochita kuzizira. Koma $150-200/kWh motsutsana ndi $70-100 ya LFP. Ndizomveka ngati kulipiritsa nthawi yocheperako sikuvomerezeka.
Pa 90% ya ntchito za forklift: LFP. Ngati wina akukankhira NMC kuti agwire ntchito, afunseni chifukwa chake.
Gawo la Money
LFP ndiyotsika mtengo mukamagula kale. 48V paketi imakhala $14,000-18,000. Lead-acid ndi $6,000-9,000.
Koma multi-shift lead-acid amatanthauza mabatire atatu pagalimoto imodzi. Ndi $18,000-27,000 m'mabatire, kuphatikiza chipinda cha batri, mpweya wabwino, chokwera, chosinthira.
LFP: batri imodzi. Malipiro a mwayi panthawi yopuma. Palibe zosinthika.
Kubweza: Miyezi 18-28.
Mlandu wa Texas 3PL, 50-mathirakiti amtundu wa $2.9 miliyoni omwe apulumutsidwa pazaka 8, kubweza mwezi wa 31 (ugowork.com). Kupambana kwakukulu sikunali mphamvu. Zinali kuchotsa mphindi 15-20 pakusinthana.
Mbendera Zofiira
Palibe zolembedwa zapa foni.
Ngati sangakuuzeni komwe maselo amachokera, lingalirani kuti sakufuna kuti mudziwe.
Zolemba za BMS sizikudziwika.
Zambiri zolephera-zofala. Ngati satha kufotokoza za selo, -kawonedwe kake, kuteteza kutentha, kutsika-kutsekera kwa temperecha-agula yotsika mtengo kwambiri.
Chitsimikizo sichimaphatikizapo nkhani yanu yogwiritsira ntchito.
Kusungirako kozizira? Kuchapira mwachangu? Werengani zopatula. Ndawona zitsimikizo zilibe pansi pa 0 digiri. Mu ozizira unyolo ntchito.
Mphamvu zovotera C/20 mukamakoka C/5.
100Ah pa 5-amp draw sikutanthauza 100Ah pa 20-amp draw. Itha kukhala 80Ah kapena kuchepera.
Kugwiritsa Ntchito Ntchito
- Nyumba yosungiramo zinthu zokhazikika,-zosintha zambiri: LFP, zokhala ndi mashifiti okhala ndi 15-20% malire.
- Kusungirako kozizira: LFP yokhala ndi kutentha kophatikizika, mpanda wa IP67. BMS ikuyenera kukhala ndi-kutchinga kocheperako-kuchapira pansi pa digiri 0 kumayambitsa kuwonongeka kosatha kwa lithiamu plating.
- 24/7 opanda mawindo olipira: LTO ngati bajeti ilola.
- Kusunga zosunga zobwezeretsera/zoyimirira zosachepera 100-zozungulira 150/chaka: Lead-acid itha kugwirabe ntchito ngati malo sakuchulukirachulukira.
Yankho
Za mafakitalekunyamula zinthu zomwe zikuyenda masinthidwe angapo-LFP, makulidwe a ntchito yanu. Osati chifukwa ndi zamakono. The lifecycle economics tsopano ili m'malo mwake.
CATL ndi BYD ali ndi 55% ya kupanga batire ya lithiamu padziko lonse lapansi. LFP ndiye gawo lakukula (SNE Research kudzera cnevpost.com, 2024). Lead{{5}asidi imakhala yomveka pamene lithiamu imawononga 5x zambiri. Zilibenso.
Ngati mukugulabe lead{{0}asidi pazida zogwiritsidwa ntchito kwambiri-ndikukulitsa nambala yolakwika.
Mafunso enieni okhudza baridi chain, -kuthamanga kwambiri, kapena kugwilizana ndi kubweza ngongole{1}tikhoza kugwiritsa ntchito manambalawa ndi ma parameters anu ogwiritsira ntchito.
