Itekhnoloji ye-Li-Ion: iindleko zeyunithi ziwa ngokukhawuleza kunoqikelelo

Molweni kwakhona, bahlobo!

Inqaku "Ixesha le-lithium-ion UPS: ingozi yomlilo okanye inyathelo elikhuselekileyo kwikamva?"Sichukumise umba weendleko eziqikelelwayo zezisombululo ze-Li-Ion (izixhobo zokugcina, iibhetri) ngokwemigaqo ethile - $/kWh. Emva koko i-forecast ye-2020 yayiyi-$ 200 / kWh. Ngoku, njengoko kunokubonwa kwi-CDPV, ixabiso le-lithium liye lahla ngaphantsi kwe-$ 150 kunye nokuhla ngokukhawuleza ngaphantsi kwe-$ 100 / kWh kuqikelelwe (ngokutsho Forbes). Itshintsha ntoni le nto, uyabuza? Okokuqala, i-gap phakathi kweendleko zeebhetri zakudala kunye nobuchwepheshe obuthembisayo, kunye nezisombululo ezisekelwe kuzo, ziyancitshiswa. Makhe sizame ukubala ngokusekelwe kwimeko yaloo nkwili yaseJapan efanayo kunye neebhetri ze-Li-Ion.

Idatha yemvelaphi

Sithatha njengedatha yokuqala:

• ixabiso lexabiso le-200 $ / kWh kwinqaku lethu malunga nokhuseleko lomlilo we-lithium
• uqikelelo lweendleko ze-300 $ / kWh kwinqaku lethu le-2018 "UPS kunye noluhlu lwebhetri ..."
• Umahluko weendleko eziqikelelweyo phakathi kwe-VRLA kunye ne-Li-Ion isisombululo ngamaxesha e-1,5-2, athathwe kwinqaku lethu le-2018 kwingozi yomlilo ye-lithium.

Ngoku masibale

1. Ukwehla okuqikelelweyo kweendleko zokuqhuba bekulumke kakhulu; ukwehla kokwenyani kukhawuleza kakhulu
2. Amandla okuqhuba emva kokuwa kweendleko zezisombululo zoshishino usebenzisa iibhetri ze-lithium-ion zizithuthi zombane: ubuninzi bamandla kwibhetri buyanda, izakhiwo ziyatshintsha, kwaye imveliso ikhula ngokukhawuleza. Unokufunda ngakumbi kwi "Uphononongo lombhali apha"
3. Umthamo webhetri oqikelelweyo wenkwili yaseJapan yayiyi-17 MWh, sithatha ixabiso leyunithi ye-lithium ngo-2017 kwisixa-mali se-300/kWh. Sifumana i-5,1 yezigidi zeedola.
4. Ngokusekelwe kwiindleko zokwenyani ezivela kwi-CDPV, ukuhla kwakumalunga ne-2% kwiminyaka eyi-30. Ngamaxabiso e-2019, sifumana ukonga malunga ne-1,5 yezigidi zeedola. Hayi kakubi huh? Ndicinga ukuba xa kwakhiwa izikhephe ezinjalo, kuyimfuneko ukuyilayisha kunye neebhetri ze-Li-Ion ngomzuzu wokugqibela, ngaphambi kokuba uhambe kwiimvavanyo zolwandle.
5. Kungacingelwa ukuba izisombululo zoshishino kwiibhetri ze-lithium, ukuhla kweendleko, ukufunda ukulinganisa kwexabiso kunye ne-lead-acid arrays yebhetri, kwenzeka ngokukhawuleza kunokuba kulindelwe. Kwinqaku le-2018, umahluko oqikelelweyo phakathi kwe-UPS kwiibhetri ze-lithium yayiyi-1,5-2 amaxesha abiza kakhulu kune-UPS yakudala. Okwangoku, lo msantsa kufuneka ube mncinci...

… iza kuqhubeka…
