Elle offre les avantages d&#039;une large couverture, d&#039;une faible consommation d&#039;\u00e9nergie, d&#039;un faible co\u00fbt, d&#039;un large r\u00e9seau et d&#039;une s\u00e9curit\u00e9 \u00e9lev\u00e9e. Adapt\u00e9e aux services IoT multi-terminaux longue distance, \u00e0 faible d\u00e9bit et \u00e0 faible consommation d&#039;\u00e9nergie, elle offre un large \u00e9ventail d&#039;applications.<\/p>\n\n\n\n<p>Le 16 juin 2016, l&#039;accord technologique NB-IoT a \u00e9t\u00e9 approuv\u00e9 lors de la r\u00e9union du groupe de sp\u00e9cification technique du r\u00e9seau d&#039;acc\u00e8s sans fil (RAN) du 3GPP. La normalisation a \u00e9t\u00e9 achev\u00e9e avec succ\u00e8s, ce qui indique que le NB-IoT entrera bient\u00f4t en phase commerciale. Les compteurs intelligents d&#039;eau, de gaz, de chauffage et d&#039;\u00e9lectricit\u00e9 sont largement promus gr\u00e2ce \u00e0 leurs capacit\u00e9s de comptage d&#039;\u00e9nergie en temps r\u00e9el, de t\u00e9l\u00e9rel\u00e8ve, de t\u00e9l\u00e9paiement et autres fonctions. Des sous-batteries au lithium ou des batteries IoT sont couramment utilis\u00e9es dans ces compteurs comme alimentation de travail et de secours. Parall\u00e8lement, les d\u00e9bitm\u00e8tres, les testeurs de gaz et autres instruments intelligents adoptent progressivement des batteries au lithium jetables afin de r\u00e9pondre aux exigences de long\u00e9vit\u00e9. On peut affirmer que le d\u00e9veloppement des instruments intelligents \u00e0 l&#039;avenir sera \u00e9troitement li\u00e9 aux batteries au lithium jetables.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2.jpg\" alt=\"combiner batterie et condensateur pour le stockage d&#039;\u00e9nergie\" class=\"wp-image-3960\" srcset=\"https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2.jpg 800w, https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2-300x300.jpg 300w, https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2-150x150.jpg 150w, https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2-768x768.jpg 768w, https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2-600x600.jpg 600w, https:\/\/www.ahotech.com\/wp-content\/uploads\/2021\/11\/combine-battery-and-capacitor-for-energy-storage-2-100x100.jpg 100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>With the acceleration of China&#8217;s urban modernization, the reform of water, heat, electricity, gas and other energy prices has been the focus of the Central Economic Work Conference in recent years.
