Ngati mwangogula kumene kapena mukufufuza mabatire a lithiamu iron phosphate (omwe amatchedwa lithiamuorLiFeP04Mu blog iyi), mukudziwa kuti amapereka ma cycle ambiri, kugawa mphamvu mofanana, komanso kulemera kwake ndi kochepa kuposa batire yofanana ndi sealed lead acid (SLA). Kodi mumadziwa kuti amathanso kutchaja mofulumira kwambiri kuposa SLA? Koma kodi mumatchaja bwanji batire ya lithiamu?

MBIRI YOCHAJITSA BATIRI YA LIFEPO4

Batire ya LiFeP04 imagwiritsa ntchito magawo ofanana a magetsi amagetsi ndi magetsi amagetsi ofanana ndi batire ya SLA. Ngakhale magawo awiriwa ndi ofanana ndipo amagwira ntchito yofanana, ubwino wa batire ya LiFeP04 ndikuti kuchuluka kwa mphamvu kumatha kukhala kwakukulu kwambiri, zomwe zimapangitsa kuti nthawi yochaja ikhale yofulumira kwambiri.

Gawo 1Kuchaja batri nthawi zambiri kumachitika pa 30%-100% (0.3C mpaka 1.0c) ya mphamvu ya batri. Gawo 1 la tchati cha SLA pamwambapa limatenga maola anayi kuti limalizidwe. Gawo 1 la batri ya lithiamu lingatenge ola limodzi kuti limalizidwe, zomwe zimapangitsa kuti batri ya lithiamu ikhalepo kuti igwiritsidwe ntchito mwachangu kwambiri kuposa SLA. Monga momwe zasonyezedwera pa tchati pamwambapa, batri ya Lithium imachajidwa pa 0.5C yokha ndipo imachajidwanso mwachangu katatu! Monga momwe zasonyezedwera pa tchati pamwambapa, batri ya Lithium imachajidwa pa 0.5C yokha ndipo imachajidwanso katatu mofulumira!
Gawo 2ndikofunikira m'mafakitale onse awiri kuti batire ifike pa 100% $ oc. Batire ya SLA imatenga maola 6 kuti amalize Gawo 2, pomwe batire ya lithiamu imatha kutenga mphindi 15 zokha. Ponseponse, batire ya thelithium imachajidwa mu maola anayi, ndipo batire ya SLA nthawi zambiri imatenga maola 10. Mu ntchito zozungulira, nthawi yochajidwa ndi yofunika kwambiri. Batire ya lithiamu imatha kuchajidwa ndikutulutsidwa kangapo patsiku, pomwe batire ya lead acid imatha kuyendetsedwa kwathunthu kamodzi patsiku.
Kumene zimasiyana pa ma profiles ochaja ndiGawo 3Batire ya lithiamu siifunikira floatcharge monga lead acid. Posungira nthawi yayitali, batire ya lithiamu siyenera kusungidwa pa 100%S0c, motero imatha kusungidwa ndi kuzungulira kwathunthu (kuchajidwa ndi kutulutsidwa) kamodzi pa miyezi 6 - 12 iliyonse kenako kusungirako kumachajidwa pa 50% SoC yokha.
Mu ntchito zoyimirira, popeza kuchuluka kwa lithiamu yodzitulutsa yokha ndi kochepa kwambiri, batire ya lithiamu imagwira ntchito bwino ngakhale itakhala kuti sinalipiridwe kwa miyezi 6 mpaka 12. Kwa nthawi yayitali, makina ochaja omwe amapereka chochaja chowonjezera kutengera mphamvu yamagetsi amalimbikitsidwa. Izi ndizofunikira kwambiri ndi mabatire athu a Bluetooth komwe gawo la Bluetooth limakoka mphamvu yaying'ono kwambiri kuchokera ku batire ngakhale silikugwiritsidwa ntchito.

Kusungirako kwa nthawi yayitali

Ngati mukufuna kusunga mabatire anu kwa nthawi yayitali, pali zinthu zingapo zofunika kuziganizira chifukwa zofunikira pakusungirako ndi zosiyana pa mabatire a SLA ndi lithiamu. Pali zifukwa ziwiri zazikulu zomwe kusunga batire ya SLA poyerekeza ndi ya Lithium kuli kosiyana.
Chifukwa choyamba ndichakuti kapangidwe ka batri kamatsimikizira malo abwino osungira. Pa batire ya SL, muyenera kuisunga pafupifupi 100% $OC kuti mupewe sulfate, zomwe zimayambitsa kusonkhanitsa makristaro a sulfate pamapepala. Kuchuluka kwa makristaro a sulfate kudzachepetsa mphamvu ya batire.
Pa batire ya lithiamu, kapangidwe ka positive terminal kamakhala kosakhazikika ma elekitironi akatha kwa nthawi yayitali. Kusakhazikika kwa positive terminal kungayambitse kutayika kwa mphamvu kosatha, Pachifukwa ichi, batire ya lithiamu iyenera kusungidwa pafupi ndi 50% Soc, yomwe imagawa ma elekitironi mofanana pama positive ndi negative terminals. Kuti mudziwe zambiri za kusungira kwa Lithium kwa nthawi yayitali, onani malangizo awa okhudza kusungira mabatire a Lithium.
Chinthu chachiwiri chomwe chimakhudza kusungirako ndi kuchuluka kwa madzi omwe amatuluka okha. Kuchuluka kwa madzi omwe amatuluka okha kwa SLabattery kumatanthauza kuti muyenera kuyiyika pa float charge kapena trickle charge kuti ikhale pafupi ndi 100% Soc kuti mupewe kutaya mphamvu yokhazikika. Pa batire ya lithiamu, yomwe ili ndi mphamvu yotsika kwambiri yotuluka ndipo siyenera kukhala pa 100% $OC, mutha kuthawa ndi kuyitanitsa kochepa kosamalira.

Ma chaja a batri ofunikira

Ndikofunika nthawi zonse kufanizira chojambulira chanu kuti chipereke mphamvu ndi magetsi oyenera a batri yomwe mukuchaja. Mwachitsanzo, simungagwiritse ntchito chojambulira cha 24V kuti muchajire batri ya 12v. Tikulimbikitsanso kuti mugwiritse ntchito chojambulira chogwirizana ndi kapangidwe ka batri yanu, kupatulapo zolemba zomwe zili pamwambapa momwe mungagwiritsire ntchito chojambulira cha SLA ndi batri ya lithiamu. Kuphatikiza apo, mukachaja batri ya lithiamu ndi chojambulira cha SLA chosazolowereka, muyenera kuonetsetsa kuti chojambuliracho chilibe mawonekedwe oyeretsera kapena mawonekedwe a batri a adead.
Ngati muli ndi mafunso okhudza mphamvu ya charger yomwe ilipo kale ndi chimodzi mwa zinthu zathu, chonde imbani foni ku USA kapena titumizireni imelo. Tidzakhala okondwa kukuthandizani ndi zosowa zanu zolipirira.
