What are the pain points in the use of batteries in large data centers

Pain point 1: Lead-acid batteries cover a large area. According to incomplete statistics, the battery room area of u200bu200ba large data center currently planned and designed accounts for about 3% to 10% of the total building area. If lead-acid batteries are used, the larger the building area of u200bu200ba large data center, the larger the battery area required. But for many IDC projects under construction, the area of u200bu200bthe computer room is limited. And most data centers hope to increase the number of cabinets as much as possible and reduce the footprint of technical facilities. Lead-acid batteries occupy a large area and have become the biggest pain point of large data centers. Pain point 2: The battery monitoring system is not perfect. At present, many computer room battery monitoring systems are not perfect, and the monitoring equipment is simple or not, and there are great safety risks. If battery failure causes UPS system downtime and key business downtime, it will cause great economic losses and sometimes even political influence. Investigations by industry organizations show that the economic loss of data centers in the financial industry for one hour of downtime is US$1,495,134, and the economic loss of data centers in the communications industry is US$2,066,245 per hour of downtime. Pain point 3: Lead-acid battery life is short and requires regular maintenance. Lead-acid battery life is generally 5 to 6 years. How to better match the life cycle of the data center, thereby reducing the total cost of use, is also the use of lead-acid batteries in the data center computer room One of the pain points in use. Practice has proved that the key factors that shorten the service life of UPS lead-acid battery packs are: the consistency of the quality and performance of the batteries varies greatly among individual batteries, which makes it difficult to guarantee the overall quality and performance of the battery packs; the battery packs use environmental temperature changes; The bag is often deeply discharged and not charged in time after discharge. More than 50% of UPS failures are caused by battery pack failure or improper maintenance of the battery. Pain point 4: The battery has higher requirements for the environment. At present, lead-acid batteries have higher requirements for the environment temperature, and the best working temperature is 20~25℃. Relevant data shows that when the ambient temperature is 25°C, the life of the valve-regulated battery will be shortened by half and the cycle life of the battery will also be shortened for every 6-10°C increase in temperature. When the ambient temperature decreases, the available capacity of the battery decreases. Therefore, improving the battery's tolerance to the environment has also become a problem to be overcome at present.
