La dur\u00e9e de fonctionnement de la lumi\u00e8re solaire en hiver est courte\u00a0?<\/p>\n

L\u2019arriv\u00e9e de la vague de froid \u00ab ajoute sans aucun doute l\u2019insulte \u00e0 l\u2019injure \u00bb pour beaucoup lampadaires solaires<\/a>. R\u00e9cemment, de nombreux utilisateurs de lampadaires solaires ont r\u00e9fl\u00e9chi sur la plate-forme r\u00e9seau au fait que les lampadaires pr\u00e9senteraient diff\u00e9rents degr\u00e9s de probl\u00e8mes, tels qu'une endurance r\u00e9duite, une vitesse de charge plus lente et une incapacit\u00e9 \u00e0 charger \u00e0 basse temp\u00e9rature en hiver.<\/p>\n

Pourquoi l'att\u00e9nuation de la dur\u00e9e de vie de la batterie LiFePO4 est-elle plus grave que celle de la batterie au lithium ternaire \u00e0 basse temp\u00e9rature\u00a0? En fait, cela est d\u00fb aux diff\u00e9rences structurelles du LiFePO4. Le mat\u00e9riau ternaire est Ni-Co Mn, qui est dispos\u00e9 selon une structure en couches, mais LiFePO4 adopte une structure olivine octa\u00e9drique, de sorte que le Batterie LiFePO4<\/a> a de meilleures performances de stabilit\u00e9 et une att\u00e9nuation de capacit\u00e9 plus contr\u00f4lable.<\/p>\n

Cependant, les diff\u00e9rences structurelles conduisent \u00e9galement \u00e0 une capacit\u00e9 inf\u00e9rieure de la batterie LiFePO4. Les ions migrent facilement dans la structure hi\u00e9rarchique du lithium ternaire, mais l'octa\u00e8dre a une plus grande r\u00e9sistance et une activit\u00e9 plus faible pendant le processus de migration, et sa puissance est plus facilement affect\u00e9e par l'environnement thermique externe.<\/p>\n

Le taux de r\u00e9tention de capacit\u00e9 des batteries LiFePO4 est d'environ 60-70% \u00e0 0 \u2103. Il se d\u00e9sint\u00e8gre jusqu'\u00e0 40-55% \u00e0 \u2013 10 \u2103 en dessous de z\u00e9ro, et seulement 20-40% \u00e0 \u2013 20 \u2103. La batterie au lithium ternaire peut toujours maintenir la capacit\u00e9 normale de la batterie d'environ 70% \u2013 80% \u00e0 \u2013 20 \u2103, ce qui explique pourquoi les lampadaires solaires \u00e9quip\u00e9s d'une batterie LiFePO4 subissent une perte de vie plus grave en hiver.<\/p>\n

Enfin<\/strong>: en peu de temps, le probl\u00e8me de l'att\u00e9nuation de l'endurance de la lumi\u00e8re solaire en hiver n'est toujours \u00ab pas de solution \u00bb. Il est ind\u00e9niable qu'\u00e0 l'heure actuelle, les lampadaires solaires pr\u00e9sentent de nombreux avantages, tels qu'une \u00e9conomie d'\u00e9nergie, une installation facile, une intelligence \u00e9lev\u00e9e, etc. Mais les utilisateurs peuvent-ils accepter le shortboard \u00e0 endurance r\u00e9duite en hiver ? Peut-\u00eatre les fabricants devraient-ils signaler le probl\u00e8me de l'\u00e9clairage \u00e0 basse temp\u00e9rature aux utilisateurs lorsqu'ils font la promotion des lampadaires, au lieu d'attendre l'hiver pour se plaindre que les lampes qu'ils ach\u00e8tent ne s'allument qu'au milieu de la nuit ou pas du tout. Bien entendu, apr\u00e8s le printemps, la lumi\u00e8re solaire d\u2019hiver retrouvera son \u00e9tat d\u2019origine. euh donc
