Misunderstanding in China EPS marketEPS is a rear-standing UPS
From the definition of IEC, the backup UPS is normal, supplied from the city to the market, and when the electricity fails, the battery pack provides energy, and power is powered by the inverter. The EPS is functionally conform to the above-described backup UPS definitions. However, saying that EPS is a backup UPS, this statement is not scientific, and it is interested in unintentional importance of EPS. Let me know that the commonly used backup UPS is a small power range, which is mostly a PC. Due to the non-focus of protection, the market demand is large, the technical content is low, the price is fierce, and there are many counterfeit goods. IT industry outside.
EPS is the emergency power supply and the focus is in emergency. It is really "raising thousands of days, the use of soldiers", in order to real emergency, it is important to have a high expected value for the reliability of EPS.
These valuable experiences are worth learning and drawing. Q: Please introduce the relevant situation of my country's biofuel ethanol industry development and pilot promotion of car ethanol gasoline? A: my country's bio-fuel ethanol industry has begun in the early stage of "10", in 2001, in order to solve a large number of "Chen Hui" treatment issues, improve the quality of the atmospheric and ecological environment, adjust the energy structure, and initiated biofuel ethanol pilot by the State Council . From the "Eleventh Five-Year Plan", according to the situation, the development of ethanol development is suspended, and multiple non-grain fuel ethanol demonstration projects or industrialization devices are built in Guangxi, Inner Mongolia, Shandong, Henan and other places. Up to now, my country's biofuel ethanol year consumption is nearly 2.6 million tons, and the industrial scale ranks third in the world.
Common imported batteries include: Sanyo battery, Panasonic battery, LG battery, Samsung lithium battery.
Analysis of the main cause of life of EPS sealing battery
Frequent charging, consumers tend to believe that no matter how much electricity is used, as long as it does not run the battery, it will only be charged, which will protect the battery is not affected by the loss. In fact, the number of cycles of the battery is certain, at 350- At 400, it is to say that charging or exceeds this number of times, it is the remarkable time of the battery, so the charging should also set up the amount of electricity to decide whether it should be added.
The effect of temperature, when the external temperature is high, the battery is high, the energy is relatively strong, while the temperature is low, the activity of the battery will decrease, the capacity is reduced, if at constant temperature, the life of the battery will increase, but Will be lowered, winter is often the peak period of battery scrap, so in winter, in winter, it is necessary to strengthen the protection of the battery.
