Ubuchwepheshe be-Li-Ion: izindleko zeyunithi zehla ngokushesha kunokubikezela

Sawubona futhi, bangane!

Esihlokweni "Isikhathi se-lithium-ion UPS: ingozi yomlilo noma isinyathelo esiphephile esiya esikhathini esizayo?"Sithinte udaba lwezindleko ezicatshangelwayo zezixazululo ze-Li-Ion (amadivayisi esitoreji, amabhethri) ngokwemibandela ethile - $/kWh. Bese isibikezelo sika-2020 besingu-$200/kWh. Manje, njengoba kungabonakala ku-CDPV, izindleko ze-lithium zehle ngaphansi kwe-$ 150 futhi ukwehla okusheshayo ngaphansi kwe-$ 100 / kWh kubikezelwe (ngokusho Forbes). Kushintshani lokhu, uyabuza? Okokuqala, igebe phakathi kwezindleko zamabhethri asendulo kanye nobuchwepheshe obuthembisayo, kanye nezixazululo ezisekelwe kuzo, liyancishiswa. Ake sizame ukubala ngokwesisekelo secala lalowo mkhumbi-ngwenya waseJapane ofanayo namabhethri e-Li-Ion.

Idatha ebomvu

Sithatha njengedatha yokuqala:

• isibikezelo sezindleko ze-200 $/kWh esihlokweni sethu mayelana nokuphepha komlilo we-lithium
• isibikezelo sezindleko sika-300 $/kWh esihlokweni sethu sika-2018 "UPS nohlu lwebhethri..."
• Umehluko wezindleko olinganiselwe phakathi kwe-VRLA ne-Li-Ion izixazululo izikhathi ezingu-1,5-2, ezithathwe esihlokweni sethu sika-2018 ngengozi yomlilo ye-lithium.

Manje ake sibale

1. Ukwehla okubikezelwe kwezindleko zamadrayivu bekuqaphe kakhulu; ukwehla kwangempela kushesha kakhulu
2. Amandla okushayela emuva kwezindleko eziwayo zezixazululo zezimboni zisebenzisa amabhethri e-lithium-ion yizimoto zikagesi: ukuminyana kwamandla ebhethri kuyanda, izakhiwo ziyashintsha, futhi ukukhiqizwa kukhula ngokushesha. Ungafunda kabanzi ku "Buyekeza umbhali lapha"
3. Umthamo webhethri olinganiselwe womkhumbi-ngwenya wase-Japan wawungu-17 MWh; sithatha izindleko zeyunithi ye-lithium ka-2017 enani lika-$300/kWh. Sithola izigidi ezingu-5,1 zamadola.
4. Uma siqala ezindlekweni zangempela ezivela ku-CDPV, khona-ke ukwehla bekucishe kube ngu-2% eminyakeni engu-30. Ngamanani entengo ka-2019, sithola ukonga okungaba amadola ayizigidi ezingu-1,5. Akukubi huh? Ngicabanga ukuthi lapho wakha izikebhe ezinjalo, kuyadingeka ukuyilayisha ngamabhethri e-Li-Ion ngomzuzu wokugcina, ngaphambi nje kokuya esivivinyweni sasolwandle.
5. Kungacatshangwa ukuthi ezixazululweni zezimboni kumabhethri e-lithium, ukwehla kwezindleko, ukulingana kwentengo yokufunda ngamaqoqo ebhethri e-lead-acid, kwenzeka ngokushesha kunalokho obekulindelwe. Esihlokweni sango-2018, umehluko olinganiselwe phakathi kwe-UPS kumabhethri e-lithium wawubiza izikhathi ezingu-1,5-2 kune-UPS yakudala. Njengamanje, leli gebe kufanele libe lincane...

… kuzoqhutshwa…
