USA: PG&E ichavaka Li-Ion kuchengetedza kubva kuTesla, NorthWestern iri kubheja pagasi

Mhoro, shamwari! Muchinyorwa "Lithium-ion UPS: imhando ipi yemabhatiri yekusarudza, LMO kana LFP?" takabata nyaya yeLi-Ion solutions (zvishandiso zvekuchengetedza, mabhatiri) emagetsi emagetsi mumasangano ega uye maindasitiri. Ini ndinopa shanduro yepfupiso yenhau pfupi dzichangoburwa kubva kuUnited States dzemusi waKurume 3, 2020 pane iyi nyaya. Chinokosha chenhau idzi ndechekuti mabhatiri e-lithium-ion ezvimiro zvakasiyana mumashandisirwo akamira ari kutsiva zvigadziriso zvemhando yepamusoro-asidi, uye Tesla akaita mupiro wakakura. Tsika yekushandisa mota dzemagetsi inoita kuti zvikwanise kutora tarisiro yakanaka uye chengetedzo yelithium mhinduro dzemagetsi masisitimu uye zvigadzirwa zvemaindasitiri zvakaita seUPS uye inoshanda yakananga ikozvino (DC) masisitimu. Aya mhinduro anonzi mabhatiri ane simba guru (High Power Batteries) muchiRussia; muzvinyorwa zveChirungu iri ndiro izwi rekuti Energy Storage System-ESS. Kutanga, ngationgororei mamiriro ezvinhu munyika yekambani yaElon Musk; mune ramangwana, tichaenderera mberi nekudhinda pane iyi nyaya zvakarongeka, sezvo "nhau kubva kumunda" dziri kusvika nokukurumidza.
