Ups does not use lithium batteries?

The IDC market is currently one of the most demanding areas for UPS. According to the statistics of relevant institutions, the compound growth rate of the domestic IDC market has reached 42.3% in the past 8 years. Among them, the IDC market is in a period of rapid growth during 2009-2011, with an annual growth rate of over 40%; macroeconomics in 2012 and 2013. As a result of the downturn, the overall market growth rate fell below 25%. Since then, on the one hand, the government has strengthened policy guidance and gradually opened up IDC license applications. On the other hand, big data, cloud computing and other industries have emerged, and the market demand for data centers has increased. In 2014, the IDC market growth rate exceeded 40% again. In 2015, the market growth rate was 39.3%. In 2016, the market growth rate also reached 38.1%. It is predicted that the market growth rate will continue to be around 40% this year and next. The IDC market is expected to reach 140 billion Yuan next year, which will obviously boost the demand of UPS.

In addition, UPS has been widely and deeply applied in the fields of industry, communication base stations, etc., and various high-end and precision equipments have also increased greatly, which not only puts higher requirements on power supply quality, but also continuity of power supply. Also need to be reliably guaranteed. With the rapid development of the UPS market, UPS battery demand is also increasing. As an important part of the UPS system, the battery has many types of specifications, and different application fields should select the corresponding battery type. The common battery types of UPS are as follows:

Lead storage battery

At present, the most commonly used lead storage battery is a valve-regulated lead-acid maintenance-free battery. The electrolyte is mainly composed of lead and sulfuric acid. It is characterized by no need to add water and acid when used, good sealing performance and relatively small volume. It is cost-effective as a UPS battery. .

In addition to maintenance-free lead storage batteries, there are open liquid lead storage batteries, which need to measure the specific gravity regularly, add water and acid. If such batteries are used, the installation environment needs to be laid with anti-corrosion bricks.

There is also a high-temperature lead storage battery in the lead storage battery, which is mainly used in communication base stations such as high-temperature base stations, frequent power failure base stations, poor environmental base stations and remote base stations, and solar/wind energy storage power stations in areas with an ambient temperature of 35 °C or higher.

2. Colloidal battery

As another kind of UPS battery, colloidal battery is called colloidal battery. The design life of colloidal battery is longer than that of ordinary lead storage battery, and the performance is more stable, so the price is relatively high.

3. Lithium battery

Lithium batteries are the first choice for green environmental protection. Lithium batteries do not contain heavy metals such as lead, nickel and chromium. Compared with ordinary lead batteries, lithium batteries have the characteristics of light weight, high energy storage and low self-discharge, but the price is relatively high.

In terms of battery selection, lead batteries are still the mainstream of the UPS market. On the other hand, research on lithium battery technology is constantly breaking through. In recent years, domestic and foreign large enterprises including Xiongtao, Shuangdeng Group, Emerson, Schneider Electric, and Eaton Power have begun to deploy UPS lithium-ion batteries.

The layout of enterprises in recent years:

Xiongtao shares:

In recent years, Xiongtao has diversified its products. Since entering the UPS industry for 20 years, Xiongtao has independently developed a series of high-quality UPS battery product power supply solutions and entered the lithium battery solution. Xiongtao's lithium battery solution, designed with Vision-specific technology, is designed for low voltage, low power and long-running applications, and has excellent performance in terms of safety, service life and backup time. And it can be charged using standard lead-acid battery charging methods.

Shuangdeng Group:

At the end of 2015, Shuangdeng Group launched a lithium-ion battery for communication. The positive electrode of the battery is made of lithium iron phosphate (LiFePO4) material, which has good safety performance and long cycle life. The battery system uses a high-performance dedicated BMS battery management module. The BMS has voltage. , current, temperature and other protection functions, and use the system to communicate well with the host; the monitoring unit automatically measures the battery charge and discharge current, charge and discharge voltage, cell surface temperature and ambient temperature.

Eaton Power:

In April 2017, Eaton Power launched a breakthrough lithium-based battery-based UPS product, which is scheduled to begin shipping in the third quarter of this year. Eaton Power began developing the 1500VA lithium battery UPS series three years ago, focusing on obtaining relevant certifications and expertise to solve the risk of lithium batteries. All certifications required to process these batteries have been obtained.

Schneider Electric:

In 2016, Schneider Electric announced that it has deployed four high-power UPS products such as Galaxy7000, GalaxyVM, GalaxyVX and SymmetraMW in the data center lithium battery application. It said that the new UPS products will be fully compatible with the lithium battery solution after 2017.

Emerson Network Power (Vertiv):

According to internal sources of Emerson Network Power, Vertiv's lithium battery solution has already landed on IDC, and the product roadmap is progressing step by step.

It can be seen that many large enterprises at home and abroad have begun to lay out the UPS lithium battery market. Although the current price of lithium batteries is 2-3 times higher than that of lead batteries, with the continuous development of lithium battery technology, its cost will also drop significantly. The price difference between the two batteries is shrinking at a rate of 20% per year. It is expected that the price of lithium batteries will gradually converge with the price of lead batteries within two to three years. Lithium batteries have the advantage of being less sensitive to temperature fluctuations and accepting temperature changes, which allows customers to reduce their cooling capacity, reduce energy consumption, and reduce floor space. In the domestic market, UPS applications such as the Shanghai Metro have begun to use lithium batteries instead of lead batteries. It is not difficult to see that lithium batteries are gradually changing the history of lead storage batteries.
