Qhathanisa amabhethri ahlukahlukene asekelayo Esitoreji Samandla Omndeni
Iliphi ibhethri elingcono kakhulu lokugcina amandla ekhaya?
Izimoto ezihlanzekile zikagesi empeleni zishayelwa amandla kagesi. Ngokwesilinganiso, baphinde bathembele ekwandiseni amabhethri e-lithium mayelana nokugcinwa kwamandla. Ikakhulukazi, kukhona ukuqhathanisa okuthile phakathi kwalokhu kokubili ngokomnotho uwonke kanye nesikhathi sokuphila.
1) Ukuhlaziywa kwesimo sokuhlolwa kwempilo kwebhethri yokulondoloza amandla
Lolu uchungechunge lwezivivinyo e-Australia, okuhlanganisa nocwaningo olukhulu lokushintshwa kwamabhethri e-lithium namabhethri e-lead-acid. Ithathe isikhathi eside. Le datha futhi isisiza ukuthi siqonde isistimu yamakhemikhali efanayo ezinhlelweni ezifanayo. Ukubola kwempilo
Isikhungo sokuhlola ibhethri sakhelwe iSustainableSkillsTrainingHubattheCanberraInstituteof Technology kanye nokuhlolwa kokusebenza sekuqalile.Kafushane lokhu kuhilela:Ukuhamba ngamabhethri kathathu ngezinsuku ezintathu kuya eminyakeni emithathuukulingisa iminyaka eyisishiyagalolunye’yokufaneleka’okujwayelekile’nsuku zonke yaleli bhethri ukusheshisa)
Izimo zokulingisa’zomhlaba wangempela’ngokusebenzisa ibhayisikili izinga lokushisa lendawo lapho amabhethri azofakwa khona; futhi,
Ukucabangela lokhu okucatshangelwayo okubili okungenhla, imijikelezo emithathu ngosuku, ngokushintsha kwezinga lokushisa kwengezwe, kushisa ehlobo 2 kubanda 1, kubanda ebusika 2 hot 1, futhi izinga lokushisa likhethwa ku-10-35degC.
Ukushicilela idatha yokusebenza, okuhlanganisa amabhethri’ayancipha amandla okugcina ngaphezu kweminyaka emithathu yokuhlolwa
Nawa amabhethri kaTesla okugcina amandla engiwathakaselayo, kanye namabhethri e-LG kanye ne-Samsung ye-NCM (isigaba sokuqala sokuhlola)
Ukuphawula: Isitoreji samandla sakwaSamsung ngokuyisisekelo sifana namabhethri emoto. Ngenxa yezidingo zokugcina amandla, kunokucatshangelwa okwengeziwe kokuklama impilo yomjikelezo.
Imiphumela yokuhlolwa kokuqala
1) Ukunciphisa amandla
2) Izici zokuncishiswa kwesigaba sokuqala
Ngaphezu kokuqedwa kokuqala kwebhethri ye-lithium ye-AVIC, impilo yomjikelezo webhethri ye-Tesla cylindrical cell imbi kakhulu.
Kulolu chungechunge lwemibiko, kunamathebula amabili okuhlola, okuhlanganisa nenani lemijikelezo yokuphila, eyodwa ihlolwe imijikelezo engu-80, enye ibe imijikelezo engu-1400.
Amazwana: Elinye lamathebula amabili yindlela yokubala amandla esetshenzisiwe. Umdwebo olandelayo awufani, kodwa unikeza kuphela isilinganiso se-SOH. Kucatshangelwa ukuthi lokhu kuguqulwa ukusebenza kahle kokufakwayo kokuqala namandla okukhiphayo.
Kusuka kuleli shadi, i-LG ne-SDI zikujiko elilinganisa ukuncipha. Ku-800, ukuncishiswa cishe ku-8%.
Idatha kaTesla, izikhathi ezingama-800 eduze ne-85%
Amabhethri e-lead-acid kanye ne-CALB (AVIC’s) awakwazi ukubambelela ngemva kwezikhathi ezingaba ngu-400
Ukuhlola okwengeziwe
Ezikhathini eziyi-1100, i-Powerwall kaTesla ingene ebangeni elingaphansi kwama-80%
Amabhethri e-LG ehla ngaphansi kuka-90% ngezikhathi ezingu-1,000. Lolu uhlelo lwebhethri lokugcina amandla olunamandla amakhulu kunawo wonke.
Amaseli amakhulu e-SDI asacishe abe ngu-92% ngemuva kwemijikelezo engu-1400, elingana neka-sony.
Esigabeni sesibili sokuhlolwa, kwakhethwa eminye imikhiqizo embalwa, kwafakwa i-TeslaPowerwall2 ebuyekeziwe, futhi kwabuyekezwa isizukulwane esisha samabhethri okugcina amandla akwa-LG.

Imiphumela yokuhlolwa kwesigaba sesibili isaqhubeka, futhi kulinganiselwa ukuthi izikhathi ezingaphezu kwe-1000 zingatholakala ukuze uthole imiphumela esobala kakhulu.
Amabhethri e-ZTE abola ngokushesha, ngcono kancane kune-SimpliPhi e-United States
I-lithium iron phosphate kanye ne-NCM111 kusenemiphumela efanayo kumjikelezo

2) Ukuhlaziywa komnotho kokugcinwa kwamandla
Ngokukhula okusheshayo kwesikali semboni, ukugcinwa kwamandla amakhemikhali okwamanje kungenye yobuchwepheshe bokugcina amandla obunokwehla ngokushesha kwezindleko. Amabhethri e-lithium-ion namabhethri e-lead-asidi asetshenziswa njengobuchwepheshe besilinganiso; indlela yejika yokuhlangenwe nakho isetshenziselwa ukubikezela ukuthambekela okuyehlayo kwezindleko zokulondoloza amandla ahlukahlukene Ⅶ, futhi amajika okuhlangenwe nakho okuhlukahlukene atholakala ngokuhlaziya idatha yomlando.
Njengamanje, izindleko zokugcinwa kwephampu ziphansi kakhulu, ngokutshalwa kwezimali kweyunithi yokugcina amandla okungaba ngu-770 yuan; izindleko zamabhethri e-lead-acid ziphakeme kancane, ku-900 yuan/kWh; izindleko zamabhethri amandla emoto kagesi kanye namabhethri e-lithium-ion okugcina amandla afanayo, ku-1550-1600 yuan/kWh Isikhathi. Kodwa-ke, mayelana nokwehla kwezindleko, izindleko zamabhethri amandla kanye namabhethri e-lithium-ion okugcinwa kwamandla kwehle ngokushesha.
Amazwana Umthombo wedatha uthi “Ucwaningo Ngamandla kanye Nomnotho Wobuchwepheshe Besitoreji Samandla Emoto Kagesi”. Ucwaningo lusebenzisa ukuhlaziywa kokuhlehla okungaqondile ukuze kulingane ubudlelwano phakathi kokuphumayo okunqwabelanayo kwamabhethri wamandla kanye nezindleko zotshalomali, futhi isibalo sokuhlehla samukela ifomu lomsebenzi wamandla17. Ukungaqiniseki kwesimo sezulu kuvezwa iphutha elijwayelekile elingu-σ lencazelo yesibikezelo, okungukuthi, ibanga lesikhawu sokuzethemba elingu-95% lesibikezelo sesilinganiso sobufakazi ngu-1.96×σ.

Idethi yokuqala yesibikezelo sezindleko zokulinganisa sesitoreji samandla ebhethri esinqanyuliwe singowezi-2021, futhi ukwehla kwezindleko zakho kubonisa ukwehla ngokushesha ekuqaleni, bese kuba ukwehla okukhulu. Inzuzo yezindleko eziphansi zokuthenga amabhethri anqanyuliwe ekuqaleni kanye nokwehla kancane kwezindleko zokusetshenziswa kwesigaba sakamuva . Ngokombono we-LCOS, isikhathi sokulinganisa se-peak-to-valley sesitoreji samandla ebhethri esinqanyuliwe singu-2025, futhi izinga lokwehla kwezindleko ngemva kwalokho lilinganiselwe.

isifinyezo:
Uma kucatshangelwa umjikelezo wangempela emkhakheni wokugcinwa kwamandla, kungenzeka ukuthi amabhethri amasha adinga ukuthuthukiswa kwezindleko ezengeziwe, futhi akulona iqiniso ukukhetha amabhethri asethathe umhlalaphansi okugcina amandla. Imodeli yezomnotho esebenzisa amandla kabusha njengengqikithi idinga ukuthi umuntu alindele ukuthi izindleko ziqhubeke. Phansi, esinye isidingo sokunaka inani lemijikelezo ewumongo, ehlukanisiwe ngandlela thize nendlela yamanje yokuthuthukisa ukuminyana kwamandla ezimotweni zikagesi ezimsulwa.
