Ibhethri le-lithium kuma-motorhomes liya ngokuya lithandwa kakhulu. Futhi ngesizathu esihle, amabhethri e-lithium-ion anezinzuzo eziningi, ikakhulukazi emakhaya aphathwayo. Ibhethri le-lithium elise-camper linikeza ukonga isisindo, amandla aphezulu kanye nokushaja okusheshayo, okwenza kube lula ukusebenzisa i-motorhome ngokuzimela. Njengoba sicabanga ngokuguqulwa kwethu okuzayo, sibheka emakethe yonke, sicabangela izinzuzo nezingozi ze-lithium, nokuthi yini okudingeka ishintshe kumadivayisi akhona.amabhethri e-lithium RV.

Kungani ibhethri le-lithium likhona emotweni?

Amabhethri ajwayelekile e-lead-acid (kanye nokuguqulwa kwawo njengebhethri le-GEL kanye ne-AGM) afakwe emakhaya aphathwayo amashumi eminyaka. Ayasebenza, kodwa lawa mabhethri awafaneleki ekhaya eliphathwayo:

• Zinzima
• Uma bekhokhiswa ngendlela engathandeki, banempilo yesevisi emfushane
• Azifaneleki kahle ezimweni eziningi zohlelo lokusebenza

Kodwa amabhethri avamile ashibhile kakhulu – yize ibhethri le-AGM linentengo yalo.

Nokho, eminyakeni yamuva nje,Ibhethri le-lithium elingu-12vAmabhethri e-lithium aseyatholakala kakhulu emakhaya aphathwayo. Amabhethri e-lithium aseseyinto yokunethezeka ethile, njengoba intengo yawo iphakeme kakhulu kunentengo yamabhethri ajwayelekile aphinde ashajwe. Kodwa anezinzuzo eziningi ezingenakususwa esandleni, futhi eziphinde zibeke intengo endaweni efanele. Kodwa okwengeziwe ngalokho ezigabeni ezimbalwa ezilandelayo.

Sasithole iveni yethu entsha ngo-2018 inamabhethri amabili e-AGM angaphakathi. Sasingafuni ukuwalahla ngokushesha futhi empeleni sasihlele ukushintshela ku-lithium kuphela ekupheleni kokuphila kwamabhethri e-AGM. Kodwa-ke, izinhlelo ziyaziwa ukuthi ziyashintsha, futhi ukuze senze isikhala eveni sokufakwa kwesifudumezi sethu sikadizili esizayo, manje sikhethe ukufaka ibhethri le-lithium endlini ephathwayo. Sizobika ngalokhu ngokuningiliziwe, kodwa-ke senze ucwaningo oluningi kusengaphambili, futhi singathanda ukwethula imiphumela kulesi sihloko.

Izisekelo zebhethri le-lithium

Okokuqala, izincazelo ezimbalwa zokucacisa amagama.

Iyini i-LiFePo4?

Ngokuphathelene namabhethri e-lithium emakhaya aphathwayo, umuntu uhlangabezana negama elithi LiFePo4 elinzima.

I-LiFePo4 ibhethri le-lithium-ion lapho i-electrode enhle iqukethe i-lithium iron phosphate esikhundleni se-lithium cobalt oxide. Lokhu kwenza leli bhethri liphephe kakhulu njengoba livimbela ukusabalala kokushisa.

Kusho ukuthini ukuthi u-Y ku-LiFePoY4?

Ukuze uthole ukuphepha, kusenesikhathiAmabhethri e-LiFePo4yayine-wattage ephansi.

Ngokuhamba kwesikhathi, lokhu kwavinjelwa ngezindlela ezahlukene, isibonelo ngokusebenzisa i-yttrium. Amabhethri anjalo abizwa ngokuthi i-LiFePoY4, futhi atholakala (kancane kakhulu) ezindlini eziphathwayo.

Ibhethri le-lithium liphephe kangakanani ku-RV?

Njengabanye abaningi, besizibuza ukuthi amabhethri e-lithium aphephe kangakanani ngempela uma esetshenziswa kuma-motorhomes. Kwenzekani engozini? Kwenzekani uma ushaja ngokweqile ngengozi?

Eqinisweni, kunezinkinga zokuphepha ngamabhethri amaningi e-lithium-ion. Yingakho kuphela uhlobo lwe-LiFePo4, olubhekwa njengoluphephile, olusetshenziswa embonini yasekhaya ephathwayo.

Ukuqina komjikelezo wamabhethri e-lithium

Ngesikhathi socwaningo lwebhethri, umuntu uhlangana namagama athi “ukuzinza komjikelezo” kanye nelithi “DoD”, ahlobene. Ngoba ukuzinza komjikelezo kungenye yezinzuzo ezinkulu zebhethri le-lithium ekhaya eliphathwayo.

I-“DoD” (Ukujula Kokukhipha) manje ikhombisa ukuthi ibhethri likhishwe malini. Ngakho-ke izinga lokukhishwa. Ngoba vele kwenza umehluko ukuthi ngikhipha ibhethri ngokuphelele (100%) noma u-10% kuphela.

Ngakho-ke ukuzinza komjikelezo kunengqondo kuphela maqondana nencazelo ye-DoD. Ngoba uma ngikhipha ibhethri ku-10% kuphela, kulula ukufinyelela izinkulungwane eziningi zemijikelezo - kodwa lokho akufanele kube wusizo.

Lokho kungaphezu kwalokho amabhethri e-lead-acid avamile angakwenza.

Izinzuzo zebhethri le-lithium ekhaya eliphathwayo

Njengoba sekushiwo, ibhethri le-lithium ekhempini linikeza izinzuzo eziningi.

• Isisindo esincane
• Umthamo ophezulu onosayizi ofanayo
• Amandla aphezulu okusetshenziswa futhi amelana nokukhishwa okujulile
• Ama-current ashaja kakhulu kanye nama-current akhiphayo
• Ukuqina komjikelezo okuphezulu
• Ukuphepha okuphezulu uma usebenzisa i-LiFePo4

Umthamo osebenzisekayo kanye nokumelana nokukhishwa okujulile kwamabhethri e-lithium

Nakuba amabhethri avamile kufanele akhishwe afike ku-50% kuphela ukuze anganciphisi kakhulu isikhathi sawo sokusebenza, amabhethri e-lithium angakhishwa futhi angakhishwa afike ku-90% wamandla awo (nokuningi).

Lokhu kusho ukuthi awukwazi ukuqhathanisa ngqo amandla phakathi kwamabhethri e-lithium namabhethri ajwayelekile e-lead-acid!

Ukusetshenziswa kwamandla okusheshayo nokushaja okulula

Nakuba amabhethri avamile angashajwa kancane kuphela, ikakhulukazi ngasekupheleni komjikelezo wokushaja, engasafuni ukusebenzisa amandla amaningi, amabhethri e-lithium awanalo le nkinga. Lokhu kukuvumela ukuthi uwalayishe ngokushesha okukhulu. Lena yindlela i-booster yokushaja ekhombisa ngayo izinzuzo zayo, kodwa futhi nesistimu yelanga isebenza ngendlela entsha ngayo. Ngoba amabhethri ajwayelekile e-lead-acid “ayabhuleka” kakhulu uma esevele egcwele. Kodwa-ke, amabhethri e-lithium amunca amandla aze agcwale.

Nakuba amabhethri e-lead-acid enenkinga yokuthi avame ukungagcwali kusuka ku-alternator (ngenxa yokusetshenziswa kwamandla aphansi ngasekupheleni komjikelezo wokushaja) bese impilo yawo yokusebenza iyaphazamiseka, amabhethri e-lithium asekhaya elihambayo ayakulimaza ngenduduzo enkulu yokushaja.

I-BMS

Amabhethri e-lithium ahlanganisa okuthiwa i-BMS, uhlelo lokuphatha ibhethri. Le BMS iqapha ibhethri futhi iyivikele ekulimaleni. Ngale ndlela, i-BMS ingavimbela ukuphuma okujulile ngokuvimbela nje ukuthi ugesi ungadonswa. I-BMS ingavimbela futhi ukushaja emazingeni okushisa aphansi kakhulu. Ngaphezu kwalokho, yenza imisebenzi ebalulekile ngaphakathi kwebhethri futhi ilinganise amaseli.

Lokhu kwenzeka ngokunethezeka ngemuva, njengomsebenzisi omsulwa akudingeki ukuthi ubhekane nakho nhlobo.

Isixhumi esibonakalayo se-Bluetooth

Amabhethri amaningi e-lithium ezindlu eziphathwayo anikeza isikhombimsebenzisi se-Bluetooth. Lokhu kuvumela ibhethri ukuthi liqashwe kusetshenziswa uhlelo lokusebenza lwe-smartphone.

Sesivele sijwayelene nale nketho evela kubalawuli bethu be-solar charge be-Renogy kanye ne-Renogy Battery Monitor, futhi sesiyijabulele lapho.

Kungcono kuma-inverter

Amabhethri e-lithium angaletha ugesi ophezulu ngaphandle kokwehla kwe-voltage, okwenza abe ngcono ukusetshenziswa ku-I-inverter engu-12vNgakho-ke uma uthanda ukusebenzisa imishini yekhofi kagesi e-motorhome noma ufuna ukusebenzisa umshini wokomisa izinwele, kunezinzuzo ngamabhethri e-lithium e-motorhome. Uma ufuna ukupheka ngogesi e-camper, awukwazi ukugwema i-lithium noma kunjalo.

Yonga isisindo ngamabhethri e-lithium ekhaya eliphathwayo

Amabhethri e-lithium alula kakhulu kunamabhethri e-lead anomthamo ofanayo. Lokhu kuyinzuzo enkulu kubahambi abaningi bezimoto ezinenkinga okufanele bahlole ibhuloho lokulinganisa ngaphambi kohambo ngalunye ukuqinisekisa ukuthi basesesendleleni endaweni esemthethweni.

Isibonelo sokubala: Ekuqaleni sasinamabhethri e-AGM angu-2x angu-95Ah. Lawa ayenesisindo esingu-2×26=52kg. Ngemva kokuguqulwa kwethu kwe-lithium sidinga ama-24kg kuphela, ngakho-ke songe ama-28kg. Futhi lokho kungenye indlela yokuqhathanisa ethokomele yebhethri le-AGM, ngoba siphinde kathathu amandla angasetshenziswa “ngendlela”!

Umthamo owengeziwe ngebhethri le-lithium ekhaya eliphathwayo

Ngenxa yokuthi ibhethri le-lithium lilula futhi lincane kunebhethri eliyinhloko elinomthamo ofanayo, ungakwazi ukuyiphendula yonke into bese ujabulela umthamo owengeziwe onesikhala nesisindo esifanayo. Isikhala sivame ukulondolozwa ngisho nangemva kokwanda komthamo.

Ngokushintsha kwethu okuzayo kusuka kumabhethri e-AGM kuya e-lithium, sizophinda kathathu amandla ethu asebenzisekayo ngenkathi sithatha isikhala esincane.

Impilo yebhethri ye-lithium

Isikhathi sokuphila kwebhethri le-lithium endlini ephathwayo singaba sikhulu kakhulu.

Lokhu kuqala ngeqiniso lokuthi ukushaja okulungile kulula futhi akunzima, nokuthi akulula kangako ukuthinta impilo yesevisi ngokushaja okungalungile nokukhipha okujulile.

Kodwa amabhethri e-lithium nawo anokuqina okukhulu komjikelezo.

Isibonelo:

Ake sithi udinga wonke umthamo webhethri le-lithium elingu-100Ah nsuku zonke. Lokho kusho ukuthi ubuzodinga umjikelezo owodwa nsuku zonke. Uma ubuhamba unyaka wonke (okungukuthi izinsuku ezingu-365), ubuzoqhubeka nebhethri lakho le-lithium iminyaka engu-3000/365 = iminyaka engu-8.22.

Kodwa-ke, iningi labahambi cishe ngeke libe semgwaqweni unyaka wonke. Kunalokho, uma sicabanga ukuthi amasonto ayi-6 eholide = izinsuku ezingama-42 bese sengeza izimpelasonto ezimbalwa ezengeziwe ezinsukwini zokuhamba eziyi-100 ngonyaka, khona-ke sizoba neminyaka engu-3000/100 = iminyaka engama-30 yokuphila. Kukhulu, akunjalo?

Akumelwe kukhohlwe: Incazelo ibhekisela ku-90% DoD. Uma udinga amandla amancane, impilo yesevisi nayo iyandiswa. Ungakulawula lokhu ngenkuthalo. Uyazi ukuthi udinga i-100Ah nsuku zonke, khona-ke ungakhetha ibhethri elikhulu kabili kunalelo. Futhi nge-spoop eyodwa uzoba ne-DoD ejwayelekile engu-50% kuphela ezokwandisa isikhathi sokuphila. Ngalokho: Ibhethri elihlala isikhathi esingaphezu kweminyaka engu-30 cishe lingashintshwa ngenxa yentuthuko yezobuchwepheshe elindelekile.

Ukuphila isikhathi eside kwesevisi kanye nomthamo ophezulu nongasetshenziswa kahle nakho kubeka intengo yebhethri le-lithium endlini ephathwayo endaweni efanele.

Isibonelo:

Ibhethri le-Bosch AGM eline-95Ah okwamanje libiza cishe u-$200.

Cishe u-50% kuphela webhethri le-AGM okufanele lisetshenziswe, okungukuthi u-42.5Ah.

Ibhethri le-lithium le-Liontron RV elinamandla afanayo angu-100Ah libiza u-$1000.

Ekuqaleni lokho kuzwakala sengathi intengo yebhethri le-lithium iphindwe kahlanu. Kodwa nge-Liontron, kungasetshenziswa amandla angaphezu kuka-90%. Esibonelweni, ihambisana namabhethri amabili e-AGM.

Manje intengo yebhethri le-lithium, elungiselelwe amandla angasetshenziswa, isengaphezu kokuphindwe kabili.

Kodwa manje ukuzinza komjikelezo kuyaqala ukusebenza. Lapha ulwazi lomenzi luyahlukahluka kakhulu - uma ungathola noma yiluphi nhlobo (ngamabhethri ajwayelekile).

• Ngamabhethri e-AGM umuntu ukhuluma ngemijikelezo efinyelela ku-1000.
• Kodwa-ke, amabhethri e-LiFePo4 akhangiswa njenganemijikelezo engaphezu kuka-5000.

Uma ibhethri le-lithium elisekhaya elihambayo lihlala imijikelezo ephindwe kahlanu, khona-keibhethri le-lithiumizodlula ibhethri le-AGM ngokwentengo nokusebenza kwayo.
