As a rechargeable battery, the requirements are: high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current charge and discharge, electrochemical stability, safety in use (not due to overcharge, over discharge and short circuit Burning or explosion caused by improper operation), wide operating temperature range, non-toxic or less toxic, and non-polluting to the environment. Lithium iron phosphate batteries using LiFePO4 as the positive electrode are good in these performance requirements.

LED becomes the protagonist of lighting
Uncle Yu of Beijing has an old-fashioned desk lamp, but has been left in the corner because he could not buy a suitable light bulb.
"The mouth of this light bulb is a hanging mouth. It needs the previous glass bulb, but the supermarket has not found such a light bulb." Yu told the author. The author then went to the supermarket in front of the house to find out the supermarket.
"You are looking for incandescent lamps? The supermarket has not sold for a few years, the kind of light bulb is heat, it will be hot for a while, and it will not be durable." The salesperson sent by the supermarket told the author.
In fact, not only in the supermarket, but also in many supermarkets in Beijing, incandescent lamps are missing. Although there are still two months away from the final limit, incandescent lamps with a history of more than 130 years have long since faded out of people's horizons.
The reason why the incandescent lamp quickly “returns to the mountain forest†is that it is a big energy consumer, in addition to “not durableâ€.
It is understood that most incandescent lamps convert 90% of the energy consumed into useless heat, and less than 10% of the energy becomes light. As for lighting time, experts say that the life of incandescent lamps usually does not exceed 1000 hours. While the traditional incandescent lamp is about to withdraw from the historical stage, the LED lighting industry has also entered the people's field of vision.
The author saw in the supermarket that a variety of LED lights were placed in the lighting container for customers to choose. "This is an LED spherical lamp that can save 80% energy." The salesperson introduced to the author.
Chen Xingyu, a member of the National Committee of the Chinese People's Political Consultative Conference, has been paying attention to the development of the LED industry for many years. In the proposal, LED lighting was recommended as an important entry point for energy conservation and emission reduction. Compared with the lamps commonly used in urban lighting, LED lighting has the advantages of energy saving and environmental protection. It is an irresistible trend to replace the traditional lighting source with a semiconductor LED light source.
Driven by national policies, China's LED industry has also ushered in great development, and its application range has been expanding. It has been gradually developed from the earliest monochromatic signal indication to explosion-proof lamps, traffic signal indications, and automotive lighting functional components. In the fields of digital products such as mobile phones and automobiles, the field of application of LEDs has been continuously expanded.
Take LED explosion-proof lamps, with the rapid development of China's petroleum, chemical, mining and other industries, the use of lighting fixtures in production, warehousing, and rescue is more and more extensive, and more and more varieties. How to prevent accidental explosions of lighting fixtures is particularly important in explosive gas hazards. LED explosion-proof lamps are not only safe, but also reduce power consumption by at least 80% compared to traditional explosion-proof lighting, saving more than 80% of electricity costs.
It is expected that the demand scale of China's special lighting industry such as explosion-proof lamps will continue to expand in the next few years. The market demand for major products will grow steadily. The increase of large-capacity and intelligent sets of electrical equipment will reach more than 20%. Explosion-proof lamps and LED explosion-proof lamps in industrial lighting fields. It has gradually become the first trend in the field of special lighting.
A set of data shows that from 2006 to 2014, the overall market size of China's LED industry increased from 35.6 billion yuan to 350.7 billion yuan, with an average annual compound growth rate of 33%. It is estimated that the annual compound growth rate of the LED market will remain above 30% from 2015 to 2017. By 2017, the LED market in China will reach 748.5 billion yuan. China has become the manufacturing base of global lighting products.
The LED industry will enter the 'mature stage' from 2015 to 2018. For LED companies, it is not technology, but more price wars. In the past, there were only a few thousand traditional lighting manufacturers in China, but now there are more than 30,000 lighting manufacturers. The tragic price war has intensified in the LED industry.
Not long ago, the “price war†of two LED companies was hit by the domestic market to the international market. It is understood that one LED company successfully bid for a foreign project, while another LED company will not hesitate to reduce the price by 10% to seize this. Engineering, the final bid was successful.
There must be many reasons behind the "price war". For example, some companies use the "bringing" strategy to omit the cost of research and development. The total cost of their products is naturally lower than their peers. Therefore, their low price may cause "price war". Secondly, most SMEs compete in the "Red Sea" field, and the homogenization of products is serious. Once again, the lack of corporate supervision in the industry, the infringing enterprises profit through the "price war" and have a good time. It is bound to encourage the arrogance of the "price war."
In addition, due to the lack of super-brands and national chain sales networks, coupled with insufficient industry standards, over-investment in the industry, uneven product quality and lack of supervision, the domestic demand lighting market has been extremely fragmented for a long time, whether it is sales or wholesale, it is still a traditional type. Therefore, the market share of the top ten lighting brands is less than 10%.
There are also many experts who suggest that China should actively play the role of the industry, and guide China's LED industry to become bigger and stronger through policies, especially to play the role of leading enterprises in the industry, and closely integrate with the innovation resources of universities and institutes. Advantages, build an industrial innovation chain, give play to the guiding role of the government's scientific and technological resources, break through the core key technologies that restrict industrial development, lead the industry to continuously improve the technological content and added value, and promote the direction of industrial development from extensive to intensive.

BMS can communicate with the host computer through the RS232 interface, so as to monitor the battery information at the upper computer terminal, including battery voltage, current, temperature, state, SOC, SOH and battery production information, etc.
â— RS485 Communication Interface
With RS485 interface, when the LiFePO4 Battery Pack is used in parallel, the main battery pack communicates with the slave battery ack through RS485 communication interface,so all the battery pack information can be viewed through the RS232 on the main Pack.
From October 1st, 15 watts and above incandescent lamps are delisted. LED lighting is bigger and stronger than price war.
According to the "China's Roadmap for Eliminating Incandescent Lamps" announced by the National Development and Reform Commission in 2011, from October 1, 2016, it is prohibited to sell and import incandescent lamps for general lighting of 15 watts or more. As traditional incandescent lamps are about to gradually withdraw from the historical arena, LED lighting will also enter the mature stage of the industry.
