Il-ħin tal-operat tad-dawl tax-xemx tax-xitwa huwa qasir?
The arrival of the cold wave is undoubtedly "adding insult to injury" to many solar street lamps. Riċentement, ħafna utenti tal-bozoz tat-toroq solari rriflettew fuq il-pjattaforma tan-netwerk li l-fanali tat-toroq se jkollhom gradi differenti ta 'problemi bħal reżistenza mqassra, veloċità tal-iċċarġjar aktar bil-mod, u inkapaċità li jiċċarġjaw f'temperaturi baxxi fix-xitwa.
Madankollu, id-differenzi strutturali jwasslu wkoll għall-kapaċità aktar baxxa tal-batterija LiFePO4. Il-jonji jemigraw faċilment fl-istruttura ġerarkika tal-litju ternarju, iżda l-octahedron għandu reżistenza akbar u attività aktar baxxa matul il-proċess ta 'migrazzjoni, u l-qawwa tiegħu hija affettwata aktar faċilment mill-ambjent tat-temperatura esterna.
The capacity retention rate of LiFePO4 batteries is about 60-70 percent at 0 degree . It decays to 40-55 percent at – 10 degree below zero, and only 20-40 percent at – 20 degree . The ternary lithium battery can still maintain the normal battery capacity of about 70 percent – 80 percent at – 20 degree , which is the reason why the solar streetlights equipped with LiFePO4 battery have a more serious life loss in winter.
