Tekinoloje ya Li-Ion: mtengo wagawo ukutsika mwachangu kuposa momwe zimaneneratu

Moni kachiwiri, abwenzi!

M'nkhaniyi "Nthawi ya lithiamu-ion UPS: ngozi yamoto kapena njira yotetezeka m'tsogolo?"Tinakhudza nkhani ya mtengo wamtengo wapatali wa Li-Ion zothetsera (zida zosungirako, mabatire) mwachindunji - $/kWh. Kenako kuneneratu kwa 2020 kunali $200/kWh. Tsopano, monga momwe tingawonere kuchokera ku CDPV, mtengo wa lithiamu watsika pansi pa $ 150 ndipo kutsika mofulumira pansi pa $ 100 / kWh kumanenedweratu (malinga ndi Forbes). Kodi izi zikusintha chiyani, mukufunsa? Choyamba, kusiyana pakati pa mtengo wa mabatire apamwamba ndi matekinoloje olonjeza, komanso mayankho ozikidwa pa iwo, akuchepetsedwa. Tiyeni tiyese kuwerengera pamaziko a nkhani ya sitima yapamadzi yaku Japan yomweyi yokhala ndi mabatire a Li-Ion.

Zambiri

Timatenga ngati data yoyamba:

• mtengo wamtengo wapatali wa 200 $/kWh kuchokera m'nkhani yathu yokhudza chitetezo chamoto cha lithiamu
• mtengo wa 300 $/kWh kuchokera munkhani yathu ya 2018 "UPS ndi gulu la batri ..."
• Kusiyana kwa mtengo pakati pa VRLA ndi Li-Ion zothetsera ndi 1,5-2 nthawi, zotengedwa m'nkhani yathu ya 2018 pa ngozi ya moto ya lithiamu.

Tsopano tiyeni tiwerenge

1. Kutsika komwe kunanenedweratu kwamitengo yamagalimoto kunali kosamala kwambiri; kutsika kwenikweni kumathamanga kwambiri
2. Zomwe zimayendetsa kutsika kwamitengo yamafakitale pogwiritsa ntchito mabatire a lithiamu-ion ndi magalimoto amagetsi: mphamvu yamagetsi mu batri ikuwonjezeka, masanjidwe akusintha, ndipo kupanga kukukulirakulira. Mutha kuwerenga zambiri mu "Olemba ndemanga apa"
3. Kuyerekeza kwa batire ya sitima yapamadzi yaku Japan inali 17 MWh; timatengera mtengo wa lithiamu mu 2017 mu kuchuluka kwa $300/kWh. Timalandira madola 5,1 miliyoni.
4. Ngati tiyambira pamtengo weniweni kuchokera ku CDPV, ndiye kuti kutsika kunali pafupifupi 2% pazaka 30. Pamitengo ya 2019, timapeza ndalama zokwana madola 1,5 miliyoni. Osati zoipa huh? Ndikuganiza kuti pomanga mabwato oterowo, ndikofunikira kuyiyika ndi mabatire a Li-Ion panthawi yomaliza, musanapite kukayesa kunyanja.
5. Tingaganize kuti zothetsera mafakitale pa mabatire a lithiamu, kutsika kwa mtengo, kuwerenga mtengo wofanana ndi magulu a batri otsogolera-acid, zikuchitika mofulumira kuposa momwe amayembekezera. M'nkhani ya 2018, kusiyana koyerekeza pakati pa UPS pa mabatire a lithiamu kunali 1,5-2 nthawi zodula kuposa UPS yapamwamba. Pakadali pano kusiyana kumeneku kuyenera kukhala kocheperako ...

… zipitilizidwa…
