1、Power device maintenance cycle
The service life of UPS components in different equipment rooms may vary because the UPS runs 7x24 hours without interruption and is limited by geographical locations and external factors (such as temperature, humidity, dust, and load ratio)，However, the main factor is to consider the overall service life. The main core role of UPS is to provide reliable power supply operation guarantee for the lower power supply equipment and facilities，That is to say, in the routine operation, when the external power grid fluctuation and power grid interruption, the continuous operation of the lower equipment and facilities can be guaranteed。
2、Emergency handling of power supply equipment
When the UPS encounters any abnormal situation (including alarm failure, overload, service life expiration, and battery failure), the lower power supply can be quickly restored and the fault can be quickly isolated by knowing the operating status of the device. Ensure the continuity of power supply。
3、Battery selection and replacement standard
1）Battery selection
Battery as the core device of energy, the most common battery in the terminal area is 12V valve controlled lead-acid battery，Advantages of choice: First, LAN batteries have relatively low energy density, and their safety is less affected by external interference than iron phosphate batteries，Second, it meets the physical conditions of the existing equipment room and provides a longer backup time with 12V batteries in series. Thirdly, at the same energy density and the same number of charge and discharge cycles, the cost advantage of lead-acid batteries is more obvious。
2）Battery replacement standards
Because there are many different brands of batteries in the market, it is difficult to unify them. The typical indicator is battery capacity，In the actual production and operation process, the load capacity of the battery is only an indicator in the battery detection process，One of the most important security risk problems, and security risk problems for data centers, computer rooms and other places is resolutely unacceptable，Such as: battery thermal runaway, battery water loss, battery leakage, early capacity loss, voltage imbalance and other risks, combined with the actual cause and situation of the site, the battery observation and inspection increases the difficulty, Therefore, it is necessary to provide monitoring standards and methods for UPS backup power supply to identify faulty batteries and backward batteries. Replace damaged batteries immediately to avoid affecting the operation of the whole battery group。
4、Battery on-line monitoring
Data room battery hundreds of thousands, human inspection of professional and technical requirements are relatively high, battery number base is large. Part of the detection means in the detection process cannot meet the corresponding detection requirements, so with the help of professional management means, to solve the new height that human resources can not reach。Battery online monitoring system is a good solution, its core role: first, real-time monitoring of battery voltage, internal resistance, temperature, current, leakage and other important parameters，Second, it has the alarm function of core risk points， Third, it can accurately evaluate the health condition of the battery, and obtain the effective basis for the replacement and step use of the battery. It not only reduces the system risk of using battery, but also avoids unnecessary waste of resources。
In summary,UPS battery risk management and maintenance based on the analysis and research of technology, through detailed analysis of the technical problems of each node, according to the needs of the selection of relevant standards in the room of power management plays a positive incentive role。
