Tá an t-am oibríochta solais gréine gheimhridh gearr?

Tá an t-am oibríochta solas gréine geimhridh gearr?


The arrival of the cold wave is undoubtedly "adding insult to injury" to many solar street lamps. Le déanaí, léirigh go leor úsáideoirí lampa sráide gréine ar an ardán líonra go mbeidh céimeanna éagsúla fadhbanna ag lampaí sráide, mar shampla marthanacht ghiorraithe, luas muirir níos moille, agus neamhábaltacht muirir i dteocht íseal sa gheimhreadh.


Why is LiFePO4 battery life attenuation more serious than ternary lithium battery at low temperature? In fact, this is due to the structural differences of LiFePO4. The ternary material is Ni-Co Mn, which is arranged in a layered structure, but LiFePO4 adopts an octahedral olivine structure, so the Ceallraí LiFePO4 has better stability performance and more controllable capacity attenuation.


Mar sin féin, tá cumas níos ísle ceallraí LiFePO4 mar thoradh ar na difríochtaí struchtúracha freisin. Imirceann na hiain go héasca i struchtúr ordlathach litiam trínártha, ach tá friotaíocht níos mó ag an octahedron agus gníomhaíocht níos ísle le linn an phróisis imirce, agus tá tionchar níos éasca ag an timpeallacht teocht seachtrach ar a chumhacht.


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.

Ar deireadh: in a short period of time, the problem of winter solar light endurance attenuation in winter is still "no solution". It is undeniable that at present, solar streetlights have many advantages, such as power saving, easy installation, high intelligence and so on. But can users accept the shortboard with reduced endurance in winter? Perhaps manufacturers should point out the problem of low-temperature lighting to users when they publicize street lamps, instead of waiting until winter to complain that the lamps they buy are only on in the middle of the night or not at all. Of course, after spring, the winter solar light will return to its original state.
