I-NationalBattery Test Center isanda kukhipha umbiko onguNombolo 11, ochaza umzuliswano waso wesithathu wokuhlolwa kwebhethri nemiphumela.
Ngizohlinzeka ngemininingwane ngezansi, kodwa uma ufuna ukubheka ngokushesha, ngingakutshela ukuthi ibhethri elisha alenzi kahle.Amabhethri ama-2 kuphela kwangu-8 ahloliwe angasebenza ngokujwayelekile.Izinkinga ezisele zisukela ekuhlulekeni kwesikhashana kuya ekuhlulekeni okuphelele.
Izinga lokuhluleka elingu-75% libi.Abahloli bathenge lawa mabhethri eminyakeni engu-2 edlule, kodwa ngiyazi ukuthi amabhethri asendlini angathembekile asangena emakethe futhi asebenzisa amakhasimende akhokhayo njengabahloli be-Beta abangaqaphile.Lokhu sekuyiminyaka eyi-10 ngemuva kokuthi uTesla ethule i-Powerwall yasekuqaleni futhi waqala ukukhiqiza amabhethri asekhaya axhunywe ngegridi eJalimane eSonnen.
Kunoma ubani ofuna ukuthenga isitoreji sebhethri lasekhaya, imiphumela iyakhungathekisa, kodwa ungakwazi ukwandisa ithuba lokuthola ibhethri elisebenzayo libe ngaphezu kuka-25% ngokusebenzisa izinyathelo ezimbili ezilandelayo...
Lokhu kuzokusiza ugweme izinhlekelele futhi kwandise kakhulu amathuba akho okuhlangenwe nakho okungenakukhathazeka.
Kodwa ukusebenzisa isistimu yebhethri yasendlini evela kumkhiqizi omkhulu, owaziwayo akuqinisekisi ukuthi ngeke isebenze kabi.Isikhungo Sikazwelonke Sokuhlola Ibhethri sihlangabezane nezinkinga ezinkulu ngemikhiqizo emikhulu.Kuhlanganisa...
Eziningi zazo zahluleka futhi kwadingeka zishintshwe ngokuphelele.Kodwa-ke, uma kudingeka, umenzi uzoshintsha isistimu yebhethri lakho, hhayi umenzi onyamalalayo lapho udinga usekelo lwakhe.
Iqiniso lokuthi amabhethri amaningi ahloliwe anezinkinga ezinkulu kuphela liqinisa isiphetho sami sangaphambilini kusukela kumbiko wesikhungo sokuhlola ibhethri ukuthi kunzima ukwenza amabhethri asekhaya athembekile. Abakhiqizi abambalwa basebenza kanzima ukuxazulula inkinga, kodwa sidinga abakhiqizi abambalwa ukuthi bakhiqize ngobuningi amabhethri aphephile nathembekile ngaphambi kokuba intengo yehle.Â
Isikhungo Sikazwelonke Sokuhlola Ibhethri sihlola amabhethri.Uma lokhu kukumangaza, kusho ukuthi ujwayele kakhulu ukuvumela okulindele kuguqulwe, yingakho imuvi entsha ye-Star Wars iyimbi kakhulu.
Ukuze bathole ulwazi lokwethembeka ngesikhathi esifanele, basebenzisa ukuhlola okusheshisiwe;ibhethri lingashajwa futhi lishajwe izikhathi ezi-3 ngosuku.Lokhu kuvumela ukulingisa iminyaka emi-3 yokugibela nsuku zonke onyakeni owodwa.
Uma ufuna ukufunda umbiko wesikhungo sokuhlola, zonke zikhona.Lesi sihloko sizogxila embikweni wabo we-10 no-11.Isihloko sami sokugcina ngalesi sihloko sabhalwa ezinyangeni ezingu-9 ezedlule, isihloko asijabulisi...
Lesi sihloko engisibhale eminyakeni emibili edlule siveze ukuthi izinga lokuphumelela kwemizuliswano emibili yokuqala yokuhlolwa lalingaphansi kwekota...
Le timu eminyakeni emithathu nengxenye edlule yayiyindikimba ye-Star Wars.Uma ungathanda, sicela uchaze inqubo yokuhlola...
Umjikelezo wokuqala wokuhlola-isigaba sokuqala-uqale ngoJuni 2016. Lena igrafu ebonisa imiphumela:
Lesi sithombe sivela Esikhungweni Sikazwelonke Sokuhlola Ibhethri, kodwa ngisicaba ukuze silingane.Uma ibukeka ingazinzile, kuyiphutha lami.
Noma yini ebomvu yimbi, futhi noma ingekho ebomvu, akusho ukuthi yinhle.Amabhethri ayisishiyagalombili angena esigabeni sokuqala, kodwa amabili kuphela awazange alimale noma ahluleke ngandlela thize.Ibhethri eliyimpumelelo-GNB PbA-yi-lead-acid, futhi lolu hlobo ngeke lusetshenziselwe isitoreji sebhethri sasekhaya esizayo.Nakuba amabhethri e-lead-acid esasetshenziswa kwezinye izinto ezifakwa ngaphandle kwegridi, awanalo ithemba lokuthi azobiza kakhulu uma esetshenziswa kugridi.Phakathi kwamabhethri e-lithium ayisithupha ahloliwe, i-Sony kuphela eyenze kahle, futhi i-Samsung ikleliswe endaweni yesibili, i-IHT izophinde ithathele umjikelezo wempilo ende webhethri ye-lithium i-LifPO4 iwuyise endlini yokubeka.
Uma ukungasebenzi kahle kulandelela amabhethri asekhaya njengebhubesi lilandelela inyamazane ye-Serengeti, ngakho-ke mayelana nokuthembeka, amabhethri akwaSony alwa namabhubesi futhi awine.I-Sony Fortelion ukuphela kwesistimu yebhethri yesiteji sokuqala esasebenza ngemva kweminyaka engu-6. Akukhona ukuthi kufakazela nje ukuthi amabhethri e-lithium anokwethenjelwa futhi ahlala isikhathi eside angenziwa, kodwa sawathola ngo-2016. Le bhethri kufanele ibe inhloso yebhethri entsha.Ithole izivivinyo zokusheshisa iminyaka engaphezu kwengu-6 futhi inikeza okulingana nokugibela kwansuku zonke ngaphezu kweminyaka eyi-9:
Uma kuqhathaniswa ne-Sony Fortelion, i-Samsung AIO ayenzanga kahle, iminyaka engu-7.6 kuphela yokuhlola okusheshisiwe ngaphambi kokwehluleka, kodwa lokhu kusewumphumela omuhle wesistimu yebhethri yasekhaya yeSigaba 1.
Ngikhulume ngaleli bhethri ukuze ngibonise ukuthi nakuba i-LG Chem iyinhlangano enkulu enenani elikhulu lamathalenta obunjiniyela, akwanele ukuvimbela amabhethri abo ekuhluphekeni kwezinkinga eziningi.Uma inkampani efana nalena inenkinga yokwenza amabhethri athembekile asendlini, kukhombisa ukuthi kunzima kangakanani.
Leli bhethri, elaziwa nangokuthi i-LG Chem RESU 1, lehlulekile ngemuva kweminyaka emibili nengxenye kuphela yokusebenza.I-LG Chem iyishintshile, kodwa ayizange iqhubeke nokuhlola.Ngaphambi kokwehluleka, ikwazile okulandelayo:
Uma ukulahlekelwa komthamo wayo kuqhubeka nokulandelana, izofinyelela ku-60% womthamo wayo wangempela phakathi nomjikelezo wansuku zonke olingisiwe weminyaka engu-6.
Umjikelezo wesibili wokuhlola uqale ngoJulayi 2017. Umphumela mubi futhi, njengoba kukhonjisiwe esithombeni esilandelayo:
Lokhu futhi bekuvela eSikhungweni Sikazwelonke Sokuhlola Ibhethri, futhi ngisichithile futhi.Kodwa izindaba ezimnandi ukuthi asikho isidingo sokuyichoboza.
Kumabhethri asendlini ayi-10 ahlolwe esigabeni sesibili, elilodwa alizange lisebenze nhlobo, futhi amabili kuphela angahlulekanga ngandlela thize.Emisebenzini emibili elandelanayo, ibhethri ye-lithium-ion ye-GNB iguga ngokweqile, futhi okwamanje ilingana neminyaka engu-4.9 yokugibela nsuku zonke, enamandla angu-47%.Lokhu kuvumela isistimu yebhethri engu-1 kuphela kweziyi-10 ukwenza lokho okufanele ikwenze.
Yize yenze umsebenzi omuhle, ilahlekelwe amandla amaningi kune-Sony Fortelion, noma izikhathi zayo zomjikelezo zingama-77% kuphela.Ngakho-ke, nakuba ithembekile njenge-Fortelion, lokhu kwenza i-Pylontech ibe yindawo yesibili phakathi kwawo wonke amabhethri asendlini ahlolwe kuze kube manje.
Uma iqhathaniswa ne-LG Chem LV esigabeni sokuqala, ikwazile ukugcina umthamo owengeziwe.Ngemuva komjikelezo wansuku zonke olingana neminyaka engu-7.6, okwamanje kulindeleke ukuthi ifinyelele umthamo wama-60%.
Umhloli uthole ingxenye enephutha ebhethrini ngemva nje kokufakwa.Isistimu kamuva yaba nokunye ukwehluleka futhi yashintshwa.Isebenza kahle manje.
Isigaba sesithathu sokuhlolwa sizoqala ngoJanuwari 2020. Njengoba kuboniswe esithombeni esingezansi, bekuhamba kahle.
Nakulokhu futhi, lo mfanekiso uvela esikhungweni sokuhlola ibhethri, kodwa akumele ngiwufice kulokhu!Ah ah ah ah!!!
Kodwa kukhona ukwehluleka okuningi kunokukhombisa ishadi.Nakuba ingekho inkinga yokubonisa ngamabhethri angu-4, amandla okukhiphayo e-PowerPlus Energy ngomjikelezo ngamunye mancane kakhulu kunalokho obekufanele, futhi ukulahleka kwamandla e-DCS kushesha kakhulu.Lokhu kusho ukuthi amabhethri asendlini amabili kuphela kwayi-10 esigabeni sesi-3 angenazo izinkinga.Kunjalo……
Phakathi kwezinhlobo ezingu-7 zamabhethri e-lithium (uhlobo okungenzeka lusetshenziselwe isitoreji sasekhaya samandla), yi-FIMER REACT 2 kuphela edlale indima yayo efanele.
Okulandelayo ukubuka okufushane kokusebenza kwebhethri ngakunye, okuhlelwe ngendlela embi ukusuka kokuhle kakhulu kuye kokubi kakhulu:
Uma umthamo wayo wesitoreji sebhethri uqhubeka nokuncipha ngokulandelana ngaleli zinga, izofinyelela ku-67% ngemva kokulingisa iminyaka engu-10 yokugibela nsuku zonke.Njengoba kufanele.
Lapho ngikhuluma ngaleli bhethri esihlokweni sokugcina, ngathi igama layo langikhumbuza i-Fizzgig evela ku-Dark Crystal, kodwa manje ngicabanga ukuthi ibhethri ye-Fozzie Bear.Noma kunjalo, qhubeka...
Ibhethri le-FZSoNick ukuphela kwebhethri lensimbi ye-sodium chloride elihloliwe.Isebenzisa usawoti oncibilikisiwe ongaba ngu-250ºC njenge-electrolyte, kodwa ukufakwa kwayo kuhle, ngakho-ke izinga lokushisa lekesi lingaphezulu kwamadigri ambalwa kuphela kunezinga lokushisa lomoya.Ububi bayo ukuthi idinga ukukhishwa ifike ku-0% masonto onke.Alukho ulwazi lokuthi lokhu kuthinta kanjani ukusebenza kahle sekukonke.Kuze kube manje, yenze umsebenzi omuhle wokugcina umthamo:
Lawa mabhethri ngokusobala ngeke alahlekelwe amandla ngesikhathi esetshenziswa, ngakho-ke iminwe ixhumene-angagcina u-98% weshajile impilo yawo yonke.Ijubane lokushaja nokukhipha lawa mabhethri e-Swedish lihamba kancane kakhulu kunalelo lamabhethri e-lithium, ngakho-ke kunzima ukuthi imindeni iwajikelezise ngokugcwele ngosuku olulodwa.Â
Ngicabanga ukuthi kungenzeka ukuthi amabhethri kasawoti oncibilikisiwe azosetshenziselwa ukugcina amandla omndeni esikhathini esizayo aphansi kakhulu, kodwa benginephutha ngaphambilini, ngakho-ke nginokugodla mayelana nesitatimende sikasawoti oncibilikisiwe.
Leli bhethri lasendlini lihlulekile enyangeni eyodwa ngemuva kokufakwa, laphinde lahluleka futhi ngemva kwenyanga.Ngenhlanhla, i-IHT ingayisiza ukuthi iphinde isebenze njalo.Ngemuva kwalezi zinkinga zokuqala, lenze kahle:
Ukwehluleka kusho ukuthi ayikwazi ukusebenza kahle, kodwa kuze kube manje, ukulahleka kwayo kwamandla kube kuphansi kakhulu.Kudingeka isikhathi esengeziwe ukubona ukuthi izohlala iphansi yini.
Kuthathe isikhathi esingaphezu konyaka ukubhekana nezinkinga, futhi i-SolaX yasishintsha yafaka uhlelo olusha lwebhethri.Entsha yasebenza kahle, kodwa yavivinywa isikhashana nje.Ukuphatha kwasekuqaleni kungokulandelayo...
Lokhu kubonisa ukuthi ngemva kweminyaka engaba ngu-8 yokugibela nsuku zonke, izofinyelela ku-60%.
Leli bhethri le-PowerPlus Energy alinaso isixhumanisi esiqondile sokuxhumana nesiguquli salo.Lokhu kusho ukuthi i-inverter ilawula ibhethri "i-loop evulekile" ngaphandle kwenzuzo yempendulo yeluphu evaliwe evela ebhethrini.Nakuba lokhu kusetha kusebenza kahle, imiphumela yezikhungo zokuhlola zangaphambilini ibonisa ukuthi ngokuvamile ayisebenzi.Â
Kulokhu, isikhungo sokuhlola sinezinkinga ekukaleni ngokunembile amandla ebhethri.Isitatimende sewaranti asikwazi ukuba ngaphansi kuka-20%, ngakho ukungaqiniseki mayelana namandla wangempela kusho ukuthi lo mkhawulo ungase uphulwe ngephutha.Isistimu yebhethri inikeze amandla amancane ngomjikelezo ngamunye kunomthamo wayo otholakalayo omisiwe, futhi ngokuvamile ingakhipha cishe u-5 kWh lapho kufanele ikwazi ukunikeza cishe u-7.9 kWh.Kuningi:
Lokhu kusebenze ngaphandle kwezinkinga isikhathi esingaphezu konyaka, kodwa amandla ehla ngokushesha.U-Sonnen ushintshe imojuli yebhethri futhi wabika ukuthi elinye lamabhethri belingasebenzi.Ukushintsha amamojula kunyuse umthamo okwesikhashana, kodwa ukwehla kwaqhubeka.Imikhawulo ye-COVID ngokusobala ibambezelekile ukulungisa inkinga.Isithombe esingezansi sibonisa ukuthi ihambe kahle ngaphambi kokwehla ngokushesha, kanye nokuthuthukiswa kwesikhashana ngemva kokushintshwa kwemojuli:
Njengoba kuboniswe esithombeni, emijikelezweni engu-800 yokuqala, i-sonnenBatterie ayizange ibonise ukwehla okukhulu komthamo.
Leli elinye ibhethri lasendlini elingaxhumani ngokuqondile nesiguquli salo.Amandla ahlinzekwa yi-DCS kumjikelezo ngamunye nawo mancane kunalokho okufanele akwazi ukukunikeza.Isikhungo sokuhlola sikuthole kunzima ukulinganisa ngokunembile amandla esistimu yebhethri, kodwa amandla aso abonakala ewohloka ngokushesha:
Uma iqhubeka ngaleli jubane, ngemva kweminyaka ecishe ibe ngu-3.5 yokulingisa ukugibela kwansuku zonke, umthamo wayo uzokwehla ube ngu-60%.
Ibhethri futhi ayinakho ukuxhumana ne-inverter yayo.I-inverter ye-SMA Sunny Island ebhanqiwe inconywe yi-Zenaji, kodwa ayikwazi ukukala amandla ngokunembile kusistimu yebhethri.Lokhu kubangele ukuthi ibhethri ngokuvamile linikeze amandla angaphansi kwesigamu okufanele likwazi ukuwanikeza kumjikelezo ngamunye.Isikhungo sokuhlola asikwazanga ukulinganisa ukuthi umthamo webhethri lehle kangakanani.
I-Zenaji isuse i-SMA Sunny Island ohlwini lwayo lwama-inverter ahambisanayo, kodwa isikhathi sesidlulile ku-National Battery Test Center.Ngenhlanhla, imindeni ivikelwe i-Australian Consumer Security, edinga ukuthi imikhiqizo "ifanele inhloso".Lokhu kusho ukuthi uthenga isitoreji sebhethri lasendlini kunoma yimuphi umphakeli, futhi bathi singasetshenziswa ne-inverter, kodwa cha, unelungelo lokusilungisa.Lokhu kungase kube ukulungiswa, ukubuyiselwa imali noma ukushintshwa.
Isikhathi sokuthumela: Dec-08-2021
