Libetri tsa lithium-ion: tataiso ea ho reka sekepe

Andrew o hlalositse hore na ke hobane'ng ha boleng bo lokela ho khethoa ha u kenya libeteri tsa lithium-ion, le libeteri tse ntle ka ho fetisisa tsa lithium iron phosphate 'marakeng tseo re li khethileng.
Libetri tsa lithium li bobebe haholo ho feta lead-acid, 'me ha ho lumeloa hore li na le matla a ka bang habeli a acid ea lead.
Senotlolo sa ho kenya betri ea lithium-ion e atlehileng e le kannete, bakeng sa ba batlang ho sebelisa theknoloji e ncha ea betri kapa esita le ho inehela liketsoaneng tsa motlakase, ke ho sebelisa mokhoa o ka holimo oa lithium-ion battery monitoring system (BMS) ka mokhoa o tšoanang. boleng ba maemo a pele.
BMS e ntle ka ho fetisisa e tla ikamahanya le boemo ba ho kenya, ha BMS e mpe ka ho fetisisa e tla ba tšireletso e thata ho qoba ho senyeha ho feletseng.
Haeba sepheo sa hau ke ho ba le sistimi e bolokehileng, e tšepahalang le e tšoarellang ea ho boloka matla ka sekepeng, u se ke oa leka ho boloka chelete ho BMS.
Empa ho mpefatsa boemo, tabeng ea lisebelisoa tsa lithium-ion, ha nako e ntse e ea, ho sebelisa lisebelisoa tse theko e tlaase, tse entsoeng hampe ho ke ke ha senya chelete e ngata feela, empa hape ho baka kotsi e kholo ea mollo ka sekepeng.
Betri ea LiFePO4 e bapatsoa e le "plug-in" e loketseng ea "lead-acid" ea betri ntle le tlhoko ea lisebelisoa tse eketsehileng tsa ho tjhaja.
Ho boleloa hore e lumellana le li-charger tsohle tsa lead-acid le li-converter tsa DC-to-DC tse teng hona joale 'marakeng.Ba na le BMS e hahelletsoeng ka har'a eona e ka hlokomelang le ho laola mesebetsi ea bona ea ho tjhaja le ho lahla ho netefatsa polokeho e kholo, ts'epo le bophelo bo bolelele.
LiFePO4 e bobebe ka 35% ho feta libeteri tse lekanang le tsa lead-acid le 40% e nyane ka boholo.E na le matla a ho ntša metsi a mangata (<1kW/120A), sekhahla sa tefiso ea 1C le bokhoni ba ho fana ka li-cycle tse 2,750 tlas'a 90% DoD, kapa ho fihla ho 5,000-50%.% DoDpotoloho.
Khampani ea Madache Victron e tsejoa ka lihlahisoa tsa eona tsa boleng bo phahameng ba motlakase, e fana ka li-betri tsa "plug-in" tsa LFP tsa 60-300Ah, tse loketseng lisebelisoa tsa 12.8 kapa 25.6V, ha li lokolloa ho 80% ea DoD kapa ho fihlela ho 5,000 cycles, e ka khona. fana ka 2,500 Feela 50% ka potoloho.
Li-tag tse bohlale li bolela hore li ka sebelisa mojule oa Bluetooth o kopaneng bakeng sa ho beha leihlo hole, empa li hloka BMS ea kantle ea Victron VE.Bus.
Moeli oa hona joale oa ho tsoa ke 100A ka 100Ah, 'me palo e phahameng ea libeteri tse tsamaisanang ke 5.
Libetri tsena tsa plug-in tse ncha tsa LFP li na le BMS e hahelletsoeng kahare le radiator e ikhethang ho pholisa betri ha e ntse e tjhaja.
Betri ea IHT "plug-in" 100Ah LiFePo4 e tsoang ho mofuta o tsebahalang oa LFP Battle Born United States e ka amohela ho tjhaja 1C le 100A discharge current (200A tlhoro ka metsotsoana e 3 feela) ntle le tšenyo.
Li boetse li kenyelletsa BMS e kentsoeng kahare e ka laolang litekanyo tsa motlakase, mocheso, ho leka-lekana ha betri, le ho fana ka tšireletso ea potoloho e khuts'oane.
Theknoloji ea thepa ea Firefly e kenyelletsa foam e entsoeng ka carbon-based porous le lisele tse likete tse bulehileng tse abang electrolyte ea sulfuric acid sebakeng se pharaletseng ho ntlafatsa katleho ea lik'hemik'hale tsa loto.
"Microbattery" mohahong oa electrolyte ea carbon foam e ka finyella sekhahla se phahameng sa ho ntša metsi, ho eketsa matla a matla le ho lelefatsa bophelo ba potoloho (<3x).
E boetse e lumella ho tjhaja kapele ha ho bapisoa le libeteri tsa khale tsa lead-acid, tse loketseng ha li tjhaja ho tsoa mohloling o lekanyelitsoeng oa ho tjhaja joalo ka solar kapa alternator.
Li-fireflies li hanana le sulfate haholo 'me li ka sebelisoa ka li-charger tse tloaelehileng tsa mekhahlelo e mengata le li-alternator regulator.
Libetri tsena tse tebileng tsa absorption glass fiber mat (AGM), ho boleloa hore carbon cathode e eketsa kamohelo ea tefiso, kahoo e potlakisa ts'ebetso ea ho tjhaja ka bongata, e eketsa palo ea lipotoloho tse teng le ho fokotsa sulfation e senyang ea lipoleiti.
Betri ea kristale e etellang pele ke acid e tiisitsoeng ea lead lead (SLA) e sebelisang elektrolyte e ncha, e sa senyeheng ea SiO2 e tla khanya ha nako e ntse e ea, e etsa hore e be matla le ho ntlafatsa ts'ebetso.
Letlapa le phahameng la lead-calcium-selenium electrode plate le electrolyte li bolokoa ka har'a pad ea microporous, kahoo lebelo la ho tjhaja betri le habeli ho feta SLA e tloaelehileng, ho tsoa ho tebile, potoloho e ba teng khafetsa, 'me e sebelisoa ho feta. mocheso o feteletseng ho feta libeteri tsa lithium-ion 'me e fana ka tshebetso e ntlafetseng Li-AGM tse ling tse ngata li na le bophelo bo bolelele ba tšebeletso.

Theknoloji ea morao-rao ea letsatsi e etsa hore ho be bonolo ho finyella leeto la ho ikemela.Duncan Kent o fana ka pale ea kahare ea tsohle tseo o li hlokang ...
