How To Select The Right Deep Cycle Battery?

Izvo Hapana Munhu Anokuudza Nezve "Deep Cycle" seChikamu

Hechino chimwe chinhu chakandishungurudza kwemakore: izwi rekuti "deep cycle" rinorohwa nemabhatiri ane hunyanzvi hwakasiyana. Mari inosvika $150 yakazadza inotungamira{{2}asidhi "yakadzika" kubva mu-bhokisi hombe uye $900 LiFePO4 pack zvese zvinotakura iyo label, asi imwe ichaita 300 macycles uye imwe inogara 4,{8}}

Iyo label inokuudza bhatiri rakagadzirirwa kudzokororwa kubuda pane kutanga injini. Ndizvo. Hapana chaanotaura nezve:

Kudzika kwaunokwanisa kuiburitsa pasina kukuvara (50% kune yakawanda lead-asidhi, 80-100% yelithium)
Kangani kaunogona kuita izvo simba risati radonha pasi pemazinga anobatsira
Chii chinoitika kana tembiricha yadzika pasi pechando
Kuti "kuchengetedza-yemahara" zvinoreva kuti hapana kugadzirisa kana kugadzirisa kushoma pane maseru akazara mvura.

Ndakaona zvikwata zvinotenga zvinhu zvichitenga zvichienderana neamp-zviyero zveawa chete, zvino ndoshaya kuti sei mabhatiri e "225Ah" achiunza nguva shoma yekushandisa pane "100Ah" lithium units dzavakatsiva. Mhinduro iri nyore: kuti 225Ah lead-asidhi bhatiri rinokwanisa kuunza zvakachengeteka ingangoita 112Ah usati watanga kuikuvadza. Iyo 100Ah lithium inokupa 80-100Ah yekugona kushandiswa. Masvomhu haanyepi.

Chisarudzo cheChemistry

Zvisarudzo zvina zvikuru. Ndichakuudza zvandinofunga pamusoro peumwe neumwe.

Ichiri nenzvimbo, asi nzvimbo iyi iri kupera. Kana iwe uine vashandi vakazvipira vanoongorora huwandu hwemvura mavhiki maviri ega ega (kwete "pavanorangarira"), tembiricha-inodzorwa bhatiri mukamuri, uye kamwe chete-kushanda kwekamwe, maseru akazara anogona kushanda. Mutengo wekutanga wakaderera chaizvo, unosvika $110-185 pakWh.

Chii chinouraya mabhatiri akazara mukushanda kwakawanda: hapana anoachengeta nemazvo. Iyo electrolyte inoda kuva 65% yemvura, 35% sulfuric acid nekurema. Sezvo mvura inoputika panguva yekuchaja, acid concentration inokwira uye inokuvadza mahwendefa. Ndakaona mabhatiri anodhura achifa mumwedzi gumi nemisere nekuti kuchengetedza kwacho kwakave kushomeka panguva yemwaka wakabatikana.

Imwe mhondi itemperature. Pa 0 degree, tarisira 30-50% kurasikirwa kwesimba. Mune zvikumbiro zvefriji? Kanganwa nezvazvo.

AGM uye Gel (VRLA)

Kutora kwangu kwechokwadi: aya ndiwo matekinoroji ekuenzanisa. Ivo vanogadzirisa dambudziko rekugadzirisa (rakavharwa, hapana kuwedzerwa kwemvura kunodiwa) asi havaunze denderedzwa rehupenyu hwekuvandudza izvo zvinopembedza mutengo wavo we2x pamusoro pemafashama. Uri kubhadhara zvakanyanya kuti udzivise dambudziko rekugadzirisa, izvo zvinogoneka, asi iyo inotungamira{{3}asidhi yemakemikari ichiri kukuganhurira kusvika ku500-1,000 macycles eAGM uye pamwe 1,000-2,000 yeGel.

AGM inochaja nekukurumidza kupfuura mafashama, ingangoita 5x nekukurumidza mune mamwe maapplication. Kana kukurumidza kutendeuka kwakakosha uye haugone kuenda lithium, AGM ine musoro. Gel inobata kuyerera kwakadzika zvirinani zvishoma asi inodhura yakawanda uye inoda chaiyo yekuchaja paramita.

Kune zvemukati maapplication uko vashandi vekuchengetedza vasina kuvimbika uye bhajeti isingatambanuke kune lithium, AGM inodzivirirwa. Asi kana ndiri kunanga: iwe unotsiva aya mabhatiri 2-3 nguva isati yeti lithium pack inoda kutsiviwa.

Lithium Iron Phosphate (LiFePO4)

Apa ndipo pandinomhara kune akawanda ekushambadzira maapplication, uye heino chikonzero.

Huwandu hwehupenyu hwekutenderera hausi kushambadzira fluff. Masero eLFP emhando yepamusoro anoburitsa 2,000-6,000 macycle pa80% kudzika kwekubuda. Ndakatsvaga mabhatiri mudzimba-mashift anosvika 4,000 macycles nekudzikira kushoma. Edza izvozvo nelead-acid uye iwe unenge uri pane yako yechitatu kana yechina kutsiva.

Kurema kunokosha kupfuura kufunga kwevanhu. Lithium pack inorema 25-40% yakaenzana nelead-asidhi simba. Mumafoni ekushandisa (mugungwa, mota, midziyo inotakurika), iyo uremu kuchengetedza inoshandura. Mumaapplication akamira, zvinoreva kuisirwa nyore uye kushomeka kwemutoro.

Iyo yekuchaja inoshanda mukana inosanganiswa nekufamba kwenguva. Lithium inoita 95-98% kutenderera-kugona rwendo maringe ne75-80% yelead-asidhi yakafashukira. Pane 10kWh zuva nezuva rekutakura bhasikoro, ingangoita 2kWh magetsi mashoma anodyiwa pazuva. Kwemakore mashanu ekushanda, kuchengetedza kwesimba chete kunogona kuvhara chikamu chakakosha chemari yekutanga yemutengo.

Yambiro Yakakosha

Imwe yakakosha caveat iyo vatengesi dzimwe nguva vanotsvedza pamusoro:haugone kubhadharisa LiFePO4 pazasi 0 dhigirii. Kuchaja mumamiriro ekutonhora kunokonzera lithium plating pane anode, ichiparadza zvachose kugona. Masisitimu emhando yeBMS anosanganisira kudzika-tembiricha yakadzikira, asi ndaongorora mabhatiri akachipa uko sensor yetembiricha yanga isina kana kubatana. Kana kuchaja kwechando chiri chikamu chekushanda kwako, simbisa kuti dziviriro iyi inoshanda chaizvo usati watumirwa.

Asi ndeipi Lithium? Apa Ndipo Pazvinonetsa

But Which Lithium? This Is Where It Gets Complicated

Kutaura kuti "Ndinoda lithium" kwakafanana nekutaura "Ndinoda mota." Pane sarudzo dzine musoro mukati mechikamu ichocho.

Cell chemistry zvine basa.LFP (lithium iron phosphate) inotonga zvikumbiro zvekutengesa nemaindasitiri nechikonzero chakanaka: ndiyo yakachengeteka lithium chemistry, inobata kushungurudzwa zvakanaka, uye inopa yakasarudzika kutenderera hupenyu. NMC (nickel manganese cobalt) inopa huwandu hwesimba repamusoro asi inouya nenjodzi yekupisa yekupisa izvo zvinoita kuti zviome kuisa inishuwarenzi mune mamwe marongero ekutengesa. LTO (lithium titanate) inobata tembiricha yakanyanyisa zvinoyevedza asi inodhura 2-3x zvimwe.

Kune akawanda B2B application, LFP ndiyo mhinduro chaiyo. Iyo simba density chirango chinopesana neNMC hachiwanzo basa kana iwe usiri kuyedza kuisa mabhatiri mu smartphone.

Cell capacity configuration inokanganisa kuvimbika.Iyo indasitiri yakamisikidza zvakanyanya kutenderedza 280Ah prismatic maseru kubva kuvagadziri vakaita seEVE neCATL. Iyo EVE LF280K yave chimwe chinhu chereferensi dhizaini. Masero akakura anoreva mashoma ekubatanidza mapoinzi mupakiti, zvinoreva mashoma anogona kutadza modes. Asi maseru akakura anodawo zvivakwa zveBMS zvakagadzirirwa kukwirira-kukwanisa kuenzana.

Masero madiki (100Ah zvichidzika) anoshanda zvakanaka kune-maapuro emagetsi akaderera. Usaite kuti chero munhu akuudze kuti kukura kunogara kuri nani, asi kune ekutengesa mapakeji pamusoro pe5kWh, iyo 280Ah chiyero chine musoro.

Kusarudzwa kweBMS kunoparadzanisa mapaketi akanaka kubva kune akaipa.Apa ndipo pandinoona yakanyanya kunaka kusiyana mumusika.

Passive balancing yakachipa. Inoshanda nekubuda ropa rakawandisa kubva kumaseru epamusoro sekupisa. Yakanakira maseru anonyatsoenderana-kufekitari, asi haikwanise kugadzirisa kusaenzana kunoitika nekufamba kwenguva.

Active balancing inodhura zvakanyanya asi inogovera zvakare chaji pakati pemaseru. JK BMS ine 2A active balancing yave iyo referensi dhizaini mukuvaka kwehunyanzvi nekuda kwechikonzero: inowedzera hupenyu hwepakiti ne15-25% mumamiriro ezvinhu epasirese apo maseru anoita misiyano mishoma yekugona.

Kana uchitenga-peki yawakavakwa, bvunza kuti BMS inoshandisa here kana kuti passive balancing. Kana mutengesi asingazivi kana kusapindura, iyo mureza mutsvuku.

Voltage architecture maitiro akananga ku48V.Zvekushandisa zvekutengesa pamusoro pe5kW, 48V masisitimu ari kuita chiyero. Iyo fizikisi iri nyore: yakapetwa kaviri voltage painongogara magetsi mahafu azvino, zvinoreva madiki conductor, kushoma kugadzirwa kwekupisa, uye kuderedzwa kurasikirwa kwekubatanidza. Kana iwe uri kugadzira yekumisikidza kutsva pane kutsiva mabhatiri aripo, funga kana 48V ine musoro kune zvaunoda simba.

MaSpecification Traps Ini Ndakadzidza Kutarisisa

Mushure mekupiswa kakati wandei, ini ndave kuziva chaizvo mibvunzo yekubvunza kana ndichiongorora vatengesi.

Zvikumbiro zvehupenyu hwemabhasikoro hazvina maturo pasina mamiriro ebvunzo.Kana mutengesi achitora "12,000 cycles," pakarepo bvunza:

Patembiricha yakadini? 25℃lab mamiriro haaratidzi-mashandisirwo chaiwo enyika.

The Specification Traps I've Learned to Watch For

Heino muenzaniso wekongiri: EVE LF280K maseru akatemerwa 6,000 cycles pa 1C/1C kusvika 80% kugona kuchengetedza. Chigadzirwa chinokwikwidza chinoti "12,000 cycles" asi chakaedzwa pa 0.5C/0.5C kusvika 70% kuchengetedza hakuna kunyanya kukwira, zvisinei nenhamba huru yemusoro. Vari kuyera zvinhu zvakasiyana.

Iyo 0.5C inoenderera yekuburitsa mutemo.Masero mazhinji eLFP akayerwa kuti arambe achibuda pa 0.5C. Izvi zvinoreva kuti 100Ah sero inofanirwa kungounza 50A nguva dzose, kwete iyo 100A kana 200A yepamusoro-soro ratings yauchaona pane BMS yakatarwa.

Ndakaona kusapindirana uku kuchikonzeresa kutadza nguva isati yakwana kakawanda. Chishandiso chinodhonza 80A nguva dzose kubva ku "100Ah" bhatiri. BMS inoti inogona kubata 150A peak. Asi maseru ari kumanikidzwa kupfuura kuenderera kwavo chiyero, kutenderera hupenyu hunodonha, uye munhu wese anopomera kunaka kwebhatiri kwete kukanganisa kwekutaura.

Kana mutoro wako ukapfuura 0.5C uchienderera, unoda maseru epamusoro kana paki yakatemerwa yakakwira inoenderera ikozvino.

Kuchembera kwekarenda kunoitika kunyangwe pasherufu.Masero eLFP anorasikirwa angangoita 2.3% kugona pagore kubva pakarenda kuchembera chete, yakazvimirira pabhasikoro. Bhatiri rakagara mudura remugovera kwemwedzi gumi nemisere rakatodzikisira 3-4% usati waisa.

Tarisa mazuva ekugadzira pamabhatiri anouya. Dzivisa stock yagara kwenguva yakareba.

Mireza Tsvuku Pakuongorora Vatengesi

Ndakagadzira chinyorwa chekuongorora pfungwa zvichienderana nezvinetso zvandakasangana nazvo:

Maximum charge ikozvino pazasi 0.2C inonyumwa.

Kana bhatiri re300Ah richitsanangura kukwira kwe50A kuchaja (0.16C), chimwe chinhu chakashata. Pamwe BMS idiki kana maseru haakwanise kubata machaji akajairwa. Hunhu LFP inogamuchira 0.5C kuchaja pasina nyaya.

Hupenyu hwemabhasikoro hunodarika 10,000 pasina nzira yakadzama.

Tekinoroji yazvino yemasero haigone kuwana nhamba idzi pasi pemamiriro ebvunzo chaiwo. Kana mumwe munhu akatora zviuru gumi nezvishanu kana makumi maviri emakumi maviri emakumi maviri emakumi maviri emakumi maviri emadhora, vanenge vachishandisa zvisizvo zvimiro zvebvunzo kana kugadzira zvakatemwa.

Zvivharo zvakavharwa zvine waranti inovharwa pakuvhurwa.

Izvi zvinodzivirira kuongorora uye kugadzirisa matambudziko. Hunhu-vatengesi vakatarisa vanoshandisa mabhaudhi sero zvinongedzo (zvinogoneka) uye vanopa BMS mukana wekuongorora. Kana vasingadi kuti utarise mukati, bvunza kuti sei.

Hapana ruzivo rwekugadzira sero.

EVE, CATL, Hithium zvitubu zviri pamutemo. Kana mutengesi akasataura nezvekutsvagirwa kwemasero, angangove ari kushandisa giredhi-B masero kana kurambwa kwekugadzira. Hurukuro dzeforum dzehunyanzvi (kunyanya DIY Solar Forum uye Marine How To) vakanyora nyaya dzemhando yepamusoro dzisina kutaurwa kwakabva masero.

Kudzivirirwa kwetembiricha kunodiwa asi hakuna kusimbiswa.

Kumbira magwaro ekuyedza-kuchajisa kwakadzikira. Ndakaongorora mabhatiri ebhajeti apo tembiricha sensor yaivepo pane redunhu bhodhi asi yanga isingashande yakabatana kune yekudzivirira logic.

Zviratidzo zvemhando yakakodzera kubhadharirwa: inoshanda kuenzanisa BMS, yakanyorwa masero ekufananidza data (kusiyana kwehukuru pazasi 2% papakiti), yakaburitswa mishumo yebvunzo ine nzira, uye waranti mazwi anotsanangura danho rekuchengetedza.
