Batire ya lithiamu mu ma motorhomes ikutchuka kwambiri. Ndipo pali chifukwa chabwino, mabatire a lithiamu-ion ali ndi zabwino zambiri, makamaka m'nyumba zoyenda. Batire ya lithiamu mu camper imapereka ndalama zochepetsera kulemera, mphamvu zambiri komanso kuyatsa mwachangu, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito motorhome yokha. Poganizira kusintha kwathu komwe kukubwera, tikuyang'ana msika wonse, poganizira zabwino ndi zoyipa za lithiamu, ndi zomwe ziyenera kusintha mu zomwe zilipo.mabatire a lithiamu RV.

Chifukwa chiyani batire ya lithiamu ili mu motorhome?

Mabatire achikhalidwe okhala ndi lead-acid (ndi zosintha zawo monga mabatire a GEL ndi AGM) akhala akuyikidwa m'nyumba zoyenda kwa zaka zambiri. Amagwira ntchito, koma mabatire awa si abwino kwambiri m'nyumba zoyenda:

• Ndi olemera
• Ndi ndalama zosavomerezeka, amakhala ndi moyo waufupi wautumiki
• Sizoyenera kugwiritsidwa ntchito pazinthu zambiri

Koma mabatire achikhalidwe ndi otsika mtengo - ngakhale kuti batire ya AGM ili ndi mtengo wake.

Komabe, m'zaka zaposachedwapa,Batri ya lithiamu ya 12vMabatire a lithiamu omwe ali mu camper akadali apamwamba kwambiri, chifukwa mtengo wawo ndi wapamwamba kwambiri kuposa mtengo wa mabatire wamba omwe amatha kubwezeretsedwanso. Koma ali ndi zabwino zambiri zomwe sizingathetsedwe mwachangu, ndipo izi zimapangitsanso kuti mtengowo ukhale wofanana. Koma zambiri za izi m'magawo angapo otsatira.

Tinalandira galimoto yathu yatsopano mu 2018 ndi mabatire awiri a AGM omwe anali m'galimoto. Sitinkafuna kuwataya nthawi yomweyo ndipo tinakonza zoti tisinthe kukhala lithiamu pokhapokha mabatire a AGM akatha. Komabe, mapulani akusintha, ndipo kuti tipeze malo mu galimoto kuti tiike chotenthetsera chathu cha dizilo, tsopano tinkakonda kuyika batire ya lithiamu m'nyumba yoyendamo. Tidzafotokoza mwatsatanetsatane za izi, koma ndithudi tinachita kafukufuku wambiri pasadakhale, ndipo tikufuna kufotokoza zotsatira zake m'nkhaniyi.

Zoyambira za batri ya Lithium

Choyamba, matanthauzo angapo kuti afotokoze bwino mawu ogwiritsidwa ntchito.

Kodi LiFePo4 ndi chiyani?

Ponena za mabatire a lithiamu a nyumba zoyenda, munthu amakumana ndi mawu osavuta kumva akuti LiFePo4.

LiFePo4 ndi batire ya lithiamu-ion yomwe ma electrode abwino amakhala ndi lithiamu iron phosphate m'malo mwa lithiamu cobalt oxide. Izi zimapangitsa batire iyi kukhala yotetezeka kwambiri chifukwa imaletsa kutentha.

Kodi Y imatanthauza chiyani mu LiFePoY4?

Posinthana ndi chitetezo, msangaMabatire a LiFePo4anali ndi mphamvu yochepa.

M'kupita kwa nthawi, izi zinathetsedwa pogwiritsa ntchito njira zosiyanasiyana, mwachitsanzo pogwiritsa ntchito yttrium. Mabatire otere amatchedwa LiFePoY4, ndipo amapezekanso (kawirikawiri) m'nyumba zoyenda.

Kodi batire ya lithiamu ndi yotetezeka bwanji mu RV?

Monga ena ambiri, tinkadzifunsa kuti mabatire a lithiamu ndi otetezeka bwanji akagwiritsidwa ntchito m'magalimoto akuluakulu. Kodi chimachitika n'chiyani pa ngozi? Nanga chimachitika n'chiyani ngati mwangozi mwawonjezera mphamvu?

Ndipotu, pali nkhawa za chitetezo m'mabatire ambiri a lithiamu-ion. Ichi ndichifukwa chake mtundu wa LiFePo4 wokha, womwe umaonedwa kuti ndi wotetezeka, ndi womwe umagwiritsidwa ntchito m'magawo a mafoni.

Kukhazikika kwa mabatire a lithiamu

Mu kafukufuku wa batri, munthu amakumana ndi mawu akuti "kukhazikika kwa cycle" ndi "DoD", omwe ndi ofanana. Chifukwa kukhazikika kwa cycle ndi chimodzi mwa zabwino zazikulu za batri ya lithiamu m'nyumba yoyenda.

"DoD" (Kuzama kwa Kutulutsa) tsopano kumasonyeza kuchuluka kwa batire yomwe yatulutsidwa. Chifukwa chake kuchuluka kwa kutulutsa. Chifukwa chake, zimapangitsa kusiyana ngati nditulutsa batire yonse (100%) kapena 10% yokha.

Chifukwa chake kukhazikika kwa kayendedwe ka zinthu kumakhala komveka bwino pokhudzana ndi DoD specification. Chifukwa ndikangotulutsa batri kufika pa 10%, zimakhala zosavuta kufika pa kayendedwe ka zinthu zambirimbiri - koma zimenezo siziyenera kukhala zothandiza.

Zimenezo ndi zambiri kuposa mabatire wamba a lead-acid omwe angachite.

Ubwino wa batri ya lithiamu m'nyumba yam'manja

Monga tanenera kale, batire ya lithiamu mu camper imapereka zabwino zambiri.

• Kulemera kochepa
• Mphamvu yayikulu yokhala ndi kukula kofanana
• Mphamvu yogwiritsidwa ntchito kwambiri komanso yolimba kutayikira madzi akuya
• Mafunde amphamvu komanso mafunde otulutsa mphamvu
• Kukhazikika kwa kayendedwe kabwino
• Chitetezo chachikulu mukamagwiritsa ntchito LiFePo4

Mphamvu yogwiritsidwa ntchito komanso kukana kutulutsa madzi kwa mabatire a lithiamu

Ngakhale mabatire wamba ayenera kutulutsidwa pa 50% yokha kuti asachepetse nthawi yogwira ntchito yawo, mabatire a lithiamu amatha kutulutsidwa pa 90% ya mphamvu yawo (ndi zina zambiri).

Izi zikutanthauza kuti simungathe kuyerekeza mwachindunji mphamvu pakati pa mabatire a lithiamu ndi mabatire wamba a lead-acid!

Kugwiritsa ntchito mphamvu mwachangu komanso kuyitanitsa kosavuta

Ngakhale mabatire achikhalidwe amatha kuyikidwa pang'onopang'ono, makamaka kumapeto kwa nthawi yoyikira, ndipo safuna kugwiritsa ntchito mphamvu zambiri, mabatire a lithiamu alibe vutoli. Izi zimakupatsani mwayi wowayika mwachangu kwambiri. Umu ndi momwe chowonjezera cha charging chimawonetsera ubwino wake, komanso solar system imagwirira ntchito bwino kwambiri. Chifukwa mabatire wamba a lead-acid "amasweka" kwambiri akadzaza kale. Komabe, mabatire a lithiamu amayamwa mphamvu mpaka atadzaza.

Ngakhale mabatire a lead-acid ali ndi vuto lakuti nthawi zambiri sadzaza ndi alternator (chifukwa cha mphamvu yochepa yomwe imagwiritsidwa ntchito kumapeto kwa nthawi yochaja) kenako moyo wawo wautumiki umachepa, mabatire a lithiamu m'nyumba yoyenda amakupangitsani kukhala omasuka kwambiri pakuchaja.

BMS

Mabatire a Lithium amaphatikiza njira yotchedwa BMS, njira yoyendetsera mabatire. BMS iyi imayang'anira batire ndikuiteteza ku kuwonongeka. Mwanjira imeneyi, BMS imatha kuletsa kutuluka kwa madzi akuya mwa kungoletsa kuti magetsi asakokedwe. BMS imathanso kuletsa kuyatsidwa kutentha komwe kuli kotsika kwambiri. Kuphatikiza apo, imagwira ntchito zofunika mkati mwa batire ndikulinganiza maselo.

Izi zimachitika bwino kumbuyo, monga wogwiritsa ntchito weniweni nthawi zambiri simuyenera kuthana nazo konse.

Chida cha Bluetooth

Mabatire ambiri a lithiamu a nyumba zoyenda amakhala ndi mawonekedwe a Bluetooth. Izi zimathandiza kuti batri liziyang'aniridwa pogwiritsa ntchito pulogalamu ya foni yam'manja.

Tikudziwa kale njira iyi kuchokera kwa owongolera athu a Renogy solar charger ndi Renogy Battery Monitor, ndipo tayamba kuiyamikira pamenepo.

Zabwino kwa ma inverters

Mabatire a Lithium amatha kupereka mphamvu zambiri popanda kutsika kwa magetsi, zomwe zimapangitsa kuti akhale abwino kugwiritsa ntchitoInverter ya 12vNgati mukufuna kugwiritsa ntchito makina amagetsi a khofi mu motorhome kapena mukufuna kugwiritsa ntchito choumitsira tsitsi, pali ubwino wokhala ndi mabatire a lithiamu mu motorhome. Ngati mukufuna kuphika pogwiritsa ntchito magetsi mu camper, simungathe kupewa lithiamu.

Sungani kulemera ndi mabatire a lithiamu m'nyumba yonyamula katundu

Mabatire a lithiamu ndi opepuka kwambiri kuposa mabatire a lead omwe ali ndi mphamvu yofanana. Izi ndi zabwino kwambiri kwa apaulendo ambiri omwe ali ndi mavuto omwe amakumana ndi magalimoto omwe amafunika kuyang'ana mlatho woyezera katundu asanayambe ulendo uliwonse kuti atsimikizire kuti akadali panjira m'dera lovomerezeka.

Chitsanzo chowerengera: Poyamba tinali ndi mabatire a 2x 95Ah AGM. Awa anali olemera 2×26=52kg. Titasintha lithiamu yathu, timangofunika 24kg yokha, kotero timasunga 28kg. Ndipo ndiko kufananiza kwina kosangalatsa kwa batire ya AGM, chifukwa tachulukitsa katatu mphamvu yogwiritsidwa ntchito "mwanjira ina"!

Mphamvu yochulukirapo ndi batire ya lithiamu m'nyumba yam'manja

Chifukwa chakuti batire ya lithiamu ndi yopepuka komanso yaying'ono kuposa batire ya lead yokhala ndi mphamvu yofanana, mutha kutembenuza chinthu chonsecho ndikusangalala ndi mphamvu zambiri yokhala ndi malo ndi kulemera kofanana. Malo nthawi zambiri amasungidwa ngakhale mphamvu itawonjezeka.

Ndi kusintha kwathu kuchokera ku mabatire a AGM kupita ku lithiamu, tiwonjezera mphamvu zathu zogwiritsira ntchito katatu pamene tikutenga malo ochepa.

Moyo wa batri ya Lithium

Moyo wa batri ya lithiamu m'nyumba yoyenda ukhoza kukhala waukulu kwambiri.

Izi zimayamba ndi mfundo yakuti kuyatsa molondola n'kosavuta komanso kosavuta, komanso kuti sikophweka kusintha moyo wa ntchito kudzera mu kuyatsa molakwika komanso kutulutsa madzi mozama.

Koma mabatire a lithiamu alinso ndi kukhazikika kwakukulu kwa kayendedwe ka magetsi.

Chitsanzo:

Tiyerekeze kuti mukufunikira mphamvu yonse ya batire ya lithiamu ya 100Ah tsiku lililonse. Izi zikutanthauza kuti mungafunike njinga imodzi patsiku. Ngati mutakhala paulendo chaka chonse (monga masiku 365), ndiye kuti mudzatha kugwiritsa ntchito batire yanu ya lithiamu kwa zaka 3000/365 = zaka 8.22.

Komabe, ambiri mwa apaulendo sangakhale paulendo chaka chonse. M'malo mwake, ngati tiganiza kuti masabata 6 a tchuthi = masiku 42 ndikuwonjezera kumapeto kwa sabata angapo ku masiku 100 oyenda pachaka, ndiye kuti tidzakhala ndi moyo wa zaka 3000/100 = zaka 30. Ndi wamkulu, sichoncho?

Sitiyenera kuiwala: Mafotokozedwe ake akutanthauza 90% DoD. Ngati mukufuna mphamvu zochepa, nthawi yogwiritsira ntchito imakulitsidwanso. Muthanso kuwongolera izi mwachangu. Kodi mukudziwa kuti mukufunika 100Ah tsiku lililonse, ndiye kuti mutha kusankha batri lomwe ndi lalikulu kawiri. Ndipo mukangogwa kamodzi mungakhale ndi DoD wamba ya 50% yomwe ingawonjezere moyo. Momwemo: Batri yomwe imakhala nthawi yayitali kuposa zaka 30 mwina ingasinthidwe chifukwa cha kupita patsogolo kwaukadaulo komwe kumayembekezeredwa.

Kutalika kwa nthawi yogwira ntchito komanso mphamvu yogwiritsira ntchito bwino kwambiri kwapangitsanso mtengo wa batri ya lithiamu m'nyumba yoyendamo kukhala wofunika kwambiri.

Chitsanzo:

Batire ya Bosch AGM yokhala ndi 95Ah pakadali pano imadula pafupifupi $200.

Pafupifupi 50% yokha ya 95Ah ya batire ya AGM ndiyo iyenera kugwiritsidwa ntchito, mwachitsanzo 42.5Ah.

Batire ya Liontron RV lithiamu yokhala ndi mphamvu yofanana ya 100Ah imadula $1000.

Poyamba zimenezo zimamveka ngati mtengo wa batire ya lithiamu kasanu kuposa mtengo wa batire ya lithiamu. Koma ndi Liontron, mphamvu yoposa 90% ingagwiritsidwe ntchito. Mu chitsanzo, ikugwirizana ndi mabatire awiri a AGM.

Tsopano mtengo wa batire ya lithiamu, yosinthidwa kuti igwiritsidwe ntchito, ukadali woposa kawiri.

Koma tsopano kukhazikika kwa kayendedwe kake kukuyamba kugwira ntchito. Apa zambiri za wopanga zimasiyana kwambiri - ngati mungapeze chilichonse (ndi mabatire wamba).

• Ndi mabatire a AGM munthu amalankhula za ma cycle okwana 1000.
• Komabe, mabatire a LiFePo4 amalengezedwa kuti ali ndi ma cycle opitilira 5000.

Ngati batire ya lithiamu yomwe ili m'nyumba yoyendamo imatenga nthawi yokwana kasanu, ndiye kutibatri ya lithiamumtengo wake udzakhala wapamwamba kuposa mtengo wa AGM.
