Yini engcono: Ibhethri ye-lithium noma ibhethri elinamandla amakhulu?

Othile ethimbeni lethu labadayisi ungidlulisele lo mbuzo wosesho ngesonto eledlule. Abaphathi bokuthengwa kwempahla balokhu beyibuza, ngakho-ke ngokusobala sidinga ukubhekana nayo ngqo.

"I-Lithium" i-chemistry. "Umthamo ophezulu" uwusayizi. Ibhethri lingaba womabili{2}}amaningi amahle. Kodwa ngiyazi ukuthi kungani lo mbuzo ulokhu uvela. Ubheka izingcaphuno, enye ithi "lithium 500Ah" ngo-$15,000, enye ithi "umthamo ophezulu 1000Ah" ngo-$8,000. Eyesibili ibukeka njengebhethri eliphindwe kabili ngesigamu senani.

Akunjalo. Uma uthenga ngokusekelwe kulowo mqondo, uzothola ukuthi kungani cishe ezinyangeni ezingu-8 lapho uthenga izinto ezishintshayo.

What Is Better: A Lithium Battery Or High Capacity Battery?

Inombolo Yekhono Kulebula

Ngihlale emihlanganweni eminingi kakhulu lapho othile ekhipha ishidi elithile futhi akhombe isilinganiso sika-Ah njengokuthi sixazulula ingxabano.

I-asidi yomthofu{{0}ayikwazi ukuletha umthamo olinganiselwe ngaphandle kokuzibhubhisa. 50% ukujula kokukhishwa kuwumkhawulo osebenzayo uma ufuna ukuphila okuphusile. Iphakethe lakho le-asidi elingu-1000Ah{4}lokuhola likunikeza u-500Ah. I-LFP isebenzisa u-80-90% DOD ngokujwayelekile-iphakethe le-500Ah liletha u-400-450Ah nsuku zonke iminyaka engu-8-10.

Sifake kabusha i-warehouse yezimpahla eziqandisiwe e-Guangdong ngonyaka odlule. 800i-Ah lead-i-acid emalolini afinyelelekayo, amahora angu-3 esikhathi sokusebenza ku- -18℃ngaphambi kokushintshana. Sifaka u-600Ah LFP ngamahora okushisa. 6.5. Amaloli afanayo, imizila efanayo. I-nameplate yehle ngo-25%, amandla angempela asebenzisekayo acishe aphindeka kabili.

Ukubanda kwenza kube kubi kakhulu. I-China Battery Industry Association (cbea.com) ihlole lokhu-I-LFP ibamba u-67% womthamo -ku-20℃, i-lead-yehla ye-asidi ibe ngu-40-50%. Beka lokho phezu komkhawulo wokukhipha kanye ne-lead-acid yakho "yezinga eliphezulu" ikunika u-20-25% walokho okushiwo ilebula.

Capacity Retention at Low Temperatures

Enye I-Capacity Trap

Amaphakethe amabili e-lithium, imodeli efanayo, umthamo olinganiselwe ofanayo. Uyabavivinya. Iphakethe A lilinganisa i-660mAh. Iphakethe B lilinganisa i-605mAh.

Bagijime imijikelezo engama-50-100. Iphakethe A lehla liye ku-580mAh futhi liyehla. Iphakethe B libamba ku-590mAh.

I-Pack A yayinezithasiselo ze-electrode ezithuthukisa izinombolo zokuqala kodwa ezifaka engozini-ukuqina kwesikhathi eside. Okuvamile, ikakhulukazi kubahlinzeki abancintisana ngentengo.

Indlela yokuyibamba:

cela idatha yempilo yomjikelezo ekujuleni kwakho kwangempela kokukhishwa, hhayi kwabo. Bacaphuna imijikelezo engu-3000 ku-50% DOD. Usebenzisa u-80% nsuku zonke. Ithini inombolo pho?

Imethrikhi eyodwa evela kunjiniyela wase-Shenzhen-ngemuva kweminyaka engu-2, ukuhluka kwamandla eseli kufanele kuhlale ngaphansi kuka-30mV. Ububanzi kunalokho kusho ukufana kwamaseli okungalungile noma ukulingana kwe-BMS okwanele.

I-LFP vs NMC vs LTO

I-NMC inokuminyana kwamandla okuphezulu. 150-250 I-Wh/kg uma iqhathaniswa no-90-160 we-LFP.

I-LFP (Lithium Iron Phosphate)

I-Thermal Runaway:~ 270 degrees

I-Cycle Life:2000-4000

I-NMC (Nickel Manganese Cobalt)

I-Thermal Runaway:~ 210 degrees

I-Cycle Life:1000-1500

Lelo gebe elingu-60-le-degree yingakho abakhiqizi baseJalimane be-forklift basuka ku-NMC. Ukuhlaziywa okukodwa okuvela kumaseli e-gabelstapler-mittendorf.com-NMC anengozi yokuqhuma ekungeneni noma ekushiseni ngokweqile i-LFP engenayo. Impilo yomjikelezo we-NMC igijima ku-1000-1500. I-LFP yenza i-2000-4000.

I-LTO ihlukile. 10,{1}} imijikelezo, ishaja ngamaminithi angu-10, isebenza kufika ku--40℃. I-Komatsu kanye ne-Toyota L&F bayisebenzisela e-Japan uchungechunge olubandayo. Kodwa u-$150-200/kWh uma uqhathanisa no-$70-100 we-LFP. Kunengqondo kuphela uma ukushaja isikhathi sokuphumula kungamukelekile.

Ku-90% wezicelo ze-forklift: LFP. Uma othile ephusha i-NMC ukuze iphathe izinto ezibonakalayo, mbuze ukuthi kungani.

Ingxenye Yemali

I-LFP ayishibhile ngaphambili. 48I-V pack isebenzisa u-$14,000-18,000. I-lead-acid ingu-$6,000-9,000.

Kodwa i-multi-shift lead-i-asidi isho amabhethri angu-3 iloli ngalinye. Lokho kungu-$18,000-27,000 wamabhethri, kanye negumbi lebhethri, umoya omncane, ukuphakamisa, ukushintshanisa ukusebenza.

I-LFP: ibhethri elilodwa. Inkokhelo yamathuba ngesikhathi sekhefu. Ayikho ingqalasizinda eshintshayo.

Lead-Acid (multi-shift) vs. LFP

Inkokhelo: izinyanga ezingu-18-28.

Total Cost of Ownership Projection (USD)

Ikesi le-Texas 3PL, 50-imikhumbi yamaloli-$2.9 million ukonga eminyakeni engu-8, inkokhelo ngenyanga 31 (ugowork.com). Ukuwina okukhulu bekungewona amandla. Ibisusa imizuzu eyi-15-20 ngokushintshana ngakunye.

Amafulegi Abomvu

Awekho amadokhumenti omthombo weseli.

Uma bengakutsheli ukuthi amaseli avelaphi, thatha ngokuthi abafuni ukuthi wazi.

Imininingwane ye-BMS ayicacile.

Ukwehluleka okuningi{0}okuyingxenye ethambekele. Uma bengakwazi ukuchaza-ukugadwa kwezinga, ukuvikelwa kwezinga lokushisa,{3}}ukuvala izinga lokushisa eliphansi{4}}bathenge eshibhe kakhulu.

Iwaranti ayifaki icala lakho lokusebenzisa.

Isitoreji esibandayo? Ukushaja okusheshayo? Funda okungafakwanga. Ngibone iziqinisekiso zingenalutho ngaphansi kwedigri engu-0. In izicelo chain abandayo.

Amandla alinganiselwe ku-C/20 uma udonsa u-C/5.

I-100Ah ekutoweni kwe-5-amp akusho ukuthi i-100Ah ku-20-amp draw. Kungaba ngu-80Ah noma ngaphansi.

Ukufaniswa Kohlelo

I-warehouse evamile,-amashifu amaningi: LFP, isayizi yokufakwa kwamashifu ngo-15-20% wemajini.
Isitoreji esibandayo: I-LFP enokushisa okuhlanganisiwe, indawo ebiyelwe nge-IP67. I-BMS kufanele ibe -neshajile yezinga eliphansi lokuvala-ukushaja okungaphansi kuka-0℃kubangela umonakalo ongunaphakade we-lithium plating.
24/7 ngaphandle kwamawindi ashajayo: LTO uma ibhajethi ivuma.
Ukwenza ikhophi yasenqolobaneni/okubekwe eceleni ngaphansi kwemijikelezo engu-100-150/ngonyaka: I-lead-asidi ingase isebenze uma isikhala singavinjelwa.

Impendulo

Okwezimboniukuphatha okubalulekile okusebenzisa amashifu amaningi-i-LFP, enosayizi womsebenzi wakho. Hhayi ngoba imfashini. I-lifecycle economics manje isivuna yona.

The Answer

I-CATL ne-BYD ibambe ngaphezulu kwama-55% wokukhiqizwa kwebhethri le-lithium emhlabeni jikelele. I-LFP ingxenye yokukhula (SNE Research via cnevpost.com, 2024). I-lead{{5}i-asidi yenza umqondo lapho i-lithium ibiza ngokuphindwe ka-5 ngaphezulu. Ayisekho.

Uma usathenga{{0}i-asidi{0}ye-asidi yezinto ezisetshenziswa kakhulu-eziphezulu, ulungiselela inombolo engalungile.

Imibuzo eqondile mayelana ne-cold chain,{0}}umjikelezo ophezulu, noma ukuhambisana kwe-retrofit{1}}singasebenzisa izinombolo ngezimiso zakho zokusebenza.
