As we all know, lithium-ion batteries have high energy density, high discharge voltage, low battery self-discharge rate, long cycle life, high charging and discharging efficiency, wide operating temperature range and many other advantages, the industry is widely believed that lithium-ion batteries are most promising to become the protagonist of the energy Internet energy storage system.
Lithium battery solar street light is an energy-saving, environmentally friendly, green and pollution-free new energy products. At the moment, with the incessant growth of lithium battery solar street light wealth, the scale of the incessant expansion, process technology has also been incessantly improved. In the solar street light industry, the choice of lithium battery street light manufacturers are also more and more. In order to improve the master's understanding of lithium batteries, today I asked the technical staff of Jiangsu KD Lighting Electric Co.
The capacity of lithium battery has a rated capacity and the actual capacity of the difference. The rated capacity refers to the design and manufacture of the battery to specify or ensure that the battery should be discharged under the inevitable discharge conditions, the minimum amount of electricity. li-ion provides for the battery at room temperature, constant current (1C) constant voltage (4.2V) controlled charging conditions for 3h, the actual capacity of the battery is the actual amount of electricity released by the battery under the inevitable discharge conditions, mainly affected by the discharge rate and temperature (so strictly (so strictly speaking, the battery capacity should specify the charging and discharging conditions). The common units of capacity are: mAh, AH (AH=1000mAh).
All local authorities are accelerating the speed of promotion of LED street lights. Chongqing planning to install 50,000 LED street lights within two years; Beijing solar street lights intended to promote the installation of 78,000 LED street lights before 2015; Jiangsu Yangzhou intends to 2015, 100% of the secondary road lighting, community lighting using LED lighting products, 30% of the city's main road lighting, the use of LED lighting products, LED street light demand of 50,000; Beijing solar street lights The end of 2012 intends to change the province's 210,000 street lights to LED street lights; not only domestic, in 2012 many foreign countries have begun to start energy-saving emission reduction plan, LED street light promotion is one of the main methods of energy-saving emission reduction plan.
In 2012, China's total production of LED street lights will reach 1.22 million, an increase of 79%. As the most critical component of LED street lights, LED street light drive power in 2012 will also be rapid growth with the rapid promotion of LED street lights, LED street light drive power companies that have the technical and financial strength as a support, will be an opportunity. According to forecasts, before 2020, LED in China's lighting market share will reach 80%, China will become the world's largest LED lighting market, the market size will exceed one trillion yuan. 2011 January-December, the national production of lamps and lighting devices reached 2.5 billion sets. 2012 for 2.8 billion sets, by 2016 production will reach 4 billion sets, the market demand from 2 billion sets in 2011 to 2.4 billion sets in 2012. Billion sets, expanded to 2.4 billion sets in 2012, and market demand is expected to break 3.5 billion sets in 2017.
If these solar street lights are using lithium battery system, then not only will save money and use better, more energy efficient and environmentally friendly. Through these data can be analyzed the significance of lithium batteries for solar street lights is very far-reaching.
