LiFePO4 Chitetezo cha Battery
Mabatire a Lithium Based akusintha mwachangu m'malo mwaukadaulo wazaka 150 wa mabatire a Lead-Acid.
Chifukwa cha kusakhazikika kwachilengedwe kwa chitsulo cha lithiamu, kafukufuku adasinthira ku batri ya lithiamu yopanda chitsulo pogwiritsa ntchito ma ayoni a lithiamu. Ngakhale kutsika pang'ono pakuchulukira kwa mphamvu, makina a lithiamu-ion ndi otetezeka, kupereka njira zina zodzitetezera polipira ndi kutulutsa. Masiku ano, lithiamu-ion ndi imodzi mwamafakitale opambana komanso otetezeka a batri omwe alipo. Maselo mabiliyoni awiri amapangidwa chaka chilichonse.
Mabatire a LiFePO4 (omwe amadziwikanso kuti Lithium Iron Phosphate) ali ndi kusintha kwakukulu pa kulemera kwa asidi, mphamvu ndi alumali. Mabatire a LiFePO4 ndi amtundu wotetezeka kwambiri wa mabatire a Lithium chifukwa satenthedwa, ndipo ngakhale atapunthwa sagwira moto. Zinthu za cathode mu mabatire a LiFePO4 sizowopsa, motero sizimawononga thanzi kapena zachilengedwe. Chifukwa cha okosijeni womangika mwamphamvu ku molekyulu, palibe chowopsa choti batire lipse ndi malawi monga momwe zimakhalira ndi Lithium-Ion. Chemistry ndi yokhazikika kotero kuti mabatire a LiFePO4 amavomereza ku charger kuchokera pa charger ya lead-acid yokhazikitsidwa ndi batire. Ngakhale zocheperako mphamvu kuposa Lithium-Ion ndi Lithium Polymer, Iron ndi Phosphate ndizochuluka komanso zotsika mtengo kuzichotsa kotero kuti ndalama zake zimakhala zomveka. Moyo wa LiFePO4 ndi pafupifupi zaka 8-10.
M'mapulogalamu omwe kulemera kumaganiziridwa, mabatire a Lithium ndi ena mwa njira zopepuka kwambiri zomwe zilipo. M'zaka zaposachedwa Lithium yapezeka m'mafakitale angapo; Lithium-Ion, Lithium Iron Phosphate, Lithium Polymer ndi zina zingapo zachilendo.
Mabatire a Lithium-Ion ndi mabatire a Lithium Polymer ndi omwe ali ndi mphamvu zambiri kuposa mabatire a Lithium, koma alibe chitetezo. Mtundu wodziwika kwambiri wa Lithium-Ion ndi LiCoO2, kapena Lithium Cobalt Oxide. Mu chemistry iyi, okosijeni sagwirizana kwambiri ndi cobalt, kotero pamene batire ikuwotcha, monga kuthamanga mofulumira kapena kutulutsa, kapena kungogwiritsa ntchito kwambiri, batire ikhoza kugwira moto. Izi zitha kukhala zowopsa makamaka m'malo othamanga kwambiri monga ndege, kapena pamapulogalamu akuluakulu monga magalimoto amagetsi. Pofuna kuthana ndi vutoli, zida zomwe zimagwiritsa ntchito mabatire a Lithium-Ion ndi Lithium Polymer zimayenera kukhala ndi zida zamagetsi zomwe nthawi zambiri zimakhala zodula kuti ziziwunika. Ngakhale mabatire Lithium Ion ndi intrinsically mkulu mphamvu kachulukidwe, patapita chaka chimodzi ntchito mphamvu ya Lithium Ion adzakhala kugwa kwambiri kuti LiFePO4 adzakhala ndi chimodzimodzi mphamvu kachulukidwe, ndipo patapita zaka ziwiri LiFePO4 adzakhala ndi mphamvu kwambiri kachulukidwe mphamvu. Choyipa china chamitundu iyi ndikuti Cobalt ikhoza kukhala yowopsa, kudzutsa nkhawa zaumoyo komanso kuwononga chilengedwe. Moyo woyembekezeredwa wa batri la Lithium-ion uli pafupifupi zaka 3 kuchokera pakupangidwa.
Lead Acid ndiukadaulo wotsimikiziridwa ndipo ukhoza kukhala wotsika mtengo. Chifukwa cha izi, amagwiritsidwabe ntchito pazambiri zamagalimoto amagetsi ndikuyamba kugwiritsa ntchito. Popeza mphamvu, kulemera, kutentha kwa ntchito ndi kuchepetsa CO2 ndizinthu zazikulu muzogwiritsira ntchito zambiri, mabatire a LiFePO4 akukhala mofulumira kukhala makampani. Ngakhale mtengo wogula woyamba wa LiFePO4 ndi wapamwamba kuposa asidi wotsogolera, moyo wautali wozungulira ukhoza kupanga chisankho chabwino pazachuma.

Tekinoloje ya batri ya lithiamu ikadali yatsopano. Pamene lusoli lapita patsogolo, kusintha monga machitidwe ophatikizira a batri (BMS) ndi ma chemistries okhazikika amkati apangitsa kuti mabatire a lithiamu omwe ali otetezeka kusiyana ndi omwe amatsogolera-asidi ndipo amapereka ubwino wambiri.
Battery Yotetezeka Kwambiri ya Lithium: the Wowonjezera4
Monga tanenera kale, njira yotchuka kwambiri ya mabatire a lithiamu RV ndi batire ya lithiamu iron phosphate (LiFePO4). Mabatire a LiFePO4 ali ndi mphamvu zochepa kwambiri kuposa mabatire a Li-ion, zomwe zimapangitsa kuti azikhala okhazikika ndikuwapanga kukhala njira yabwino kwambiri yopangira ma RV.
Phindu lina lachitetezo cha LiFePO4 ndikuti lithiamu iron phosphate si poizoni. Chifukwa chake, mutha kutaya mosavuta kuposa mabatire a lead-acid ndi Li-ion.
Ubwino wa Mabatire a Lithium
Kuganizira zachitetezo cha mabatire a LiFePO4 mwachiwonekere ndikofunikira. Komabe, maubwino ena ambiri amathandizira kupanga mabatire a LiFePO4 kukhala osankha bwino pangolo ya gofu, galimoto yamagetsi(EV) , magalimoto onse amtundu (ATV&UTV), magalimoto osangalatsa(RV), scooter yamagetsi.
Kutalika kwa Moyo Wautali
Anthu ena amatsutsa mtengo wapamwamba wa mabatire a lithiamu, omwe amatha kufika $ 1,000 iliyonse. Komabe, mabatire a lithiamu amatha kuwirikiza nthawi khumi kuposa batire ya acid-lead-acid yomwe nthawi zambiri imabweretsa kupulumutsa ndalama pakapita nthawi.
Otetezeka kuposa Lead Acid kapena AGM
Ngakhale mabatire ambiri a lead-acid kapena AGM amasindikizidwa kuti atetezeke, saperekabe zinthu zambiri zachitetezo zomwe mabatire a lithiamu amachita.
Mabatire a lithiamu nthawi zambiri amakhala ndi makina ophatikizira a batire (BMS) omwe amawathandiza kuti azilipiritsa ndikugwira ntchito moyenera komanso mosatekeseka. Mabatire a lead-acid amathanso kuwonongeka komanso kutenthedwa kwambiri akaperekedwa ndi kutulutsidwa koma alibe BMS yowathandiza kuwateteza.
Kuphatikiza apo, mabatire a LiFePO4 amapangidwa kuchokera kuzinthu zopanda poizoni zomwe zimakana kuthawa kwamafuta. Izi zimangowonjezera chitetezo chowonjezera kwa wogwiritsa ntchito komanso chilengedwe.
Kuchuluka kwa Battery
Ubwino wina wa mabatire a lithiamu ndikuti ali ndi mphamvu yogwiritsira ntchito kwambiri poyerekeza ndi mabatire a lead-acid.
Mutha kutulutsa batire la acid-acid mosatetezeka mpaka pafupifupi 50% ya kuchuluka kwake musanayambe kuwononga batire. Izi zikutanthauza kuti ngati batire ya lead-acid ikuvotera pa 100 amp-hours, mumangokhala ndi 50 amp-hours yamphamvu yogwiritsira ntchito musanayambe kuwononga batire. Izi zimachepetsa mphamvu yake yamtsogolo komanso moyo wake wonse.
Mosiyana ndi izi, mutha kutulutsa batire ya lithiamu pafupifupi popanda kuwononga. Komabe, anthu ambiri samawachotsa pansi pa 20% asanawonjezere. Ngakhale mutatsatira lamulo losamalitsa ili, batire ya lithiamu ya 100 amp-hour imapereka pafupifupi 80 amp-maola isanafunikire kuwonjezeredwa.
Kusamalira Kochepa
Oyang'anira ophatikizika a BMS ndikuthandizira kusunga batri yanu ya lithiamu, kuchotsa kufunikira kochita izi nokha.
BMS imaonetsetsa kuti batire silikuchulukirachulukira, imawerengera momwe mabatire amayendera, kuyang'anira ndikuwongolera kutentha, ndikuwunika thanzi ndi chitetezo cha mabatire.
Zochepa Zolemera
Pali njira ziwiri zomwe mabatire a lithiamu angachepetse kulemera kwa batri yanu.
Monga tanenera kale, mabatire a lithiamu ali ndi mphamvu yogwiritsira ntchito kuposa mabatire a lead-acid. Izi nthawi zambiri zimakupatsani mwayi wosowa mabatire a lithiamu ochepa m'dongosolo lanu kuti mukwaniritse mphamvu yofanana ndi dongosolo la lead-acid. Kuphatikiza apo, batire ya lithiamu imalemera pafupifupi theka la batri ya acid-acid yokhala ndi mphamvu yofanana.
Zowonjezera
Monga tafotokozera, mabatire a lithiamu ndi othandiza kwambiri kuposa mabatire a lead-acid. Ngakhale ndi mphamvu yofananira, mabatire a lithiamu amapereka mphamvu zowonjezera. Amatulutsanso pamlingo wokhazikika kuposa mabatire a asidi amtovu.
Izi zimakulolani kuti mugwiritse ntchito nthawi yayitali popanda kubwezeretsanso mabatire anu, zomwe zimakhala zothandiza makamaka mukamayendetsa boondo ndikukulolani kuti muchepetse kugwiritsa ntchito jenereta ndikuwonjezera mphamvu yanu ya dzuwa.
Zotsika mtengo Pazonse
Ngakhale kuti mabatire a lithiamu poyamba amawononga ndalama zambiri kuposa anzawo a lead-acid, kuti amakhala nthawi yayitali 6-10 zikutanthauza kuti pamapeto pake mudzasunga ndalama pakapita nthawi.
JB BATTERY ndi katswiri, wodziwa zambiri, komanso gulu lamphamvu laukadaulo la opanga mabatire a lifepo4, kuphatikiza ma cell + BMS + kasamalidwe ka Pack ndikusintha mwamakonda. Timayang'ana kwambiri pakukula ndi kupanga makonda a mabatire a lithiamu iron phosphate.
