UPS电源的工作方式根据用电设备对供电可靠性和连续性的要求可分为单一式、并联式、冗余式和并联冗余式等方式。

根据用电设备对供电可靠性和管理方便的要求也可分为分散式、集中式、分散与集中相结合三种方式。分散式UPS供电采用的设备容量都比较小，支持时间较短，适合用于一些办公区和控制室;集中式UPS供电适合一些要求支持时间较长和较大型的计算机网络机房等。

应当根据甲方需求来确定采用哪种UPS的供电方式和容量。集中设置的UPS电源容量的统计需由设计方与业主密切配合，并考虑所选UPS产品的转换效率。尤其是功率较大时，UPS转换效率非常重要，效率高就可节省初期投资和长期能源损耗的费用。

电池的使用寿命与环境温度密切相关，电池处于较低温度时，蓄电池中的锌板容易粉化，失去蓄电性能，造成永久性损坏；温度过高时，电池的容量也会下降，情况严重时会造成永久性损坏。根据电池生产厂家的技术规范，电池的最佳使用温度是2~25℃，在该温度范围使用，可延长电池的使用寿命。

The working mode of UPS power supply can be divided into single type, parallel type, redundant type and parallel redundant type according to the requirements of electrical equipment for power supply reliability and continuity.

According to the requirements of power supply reliability and convenient management of electric equipment, it can also be divided into three ways: decentralized, centralized and the combination of decentralized and centralized. The equipment capacity of distributed UPS power supply is relatively small and the support time is short, which is suitable for some office areas and control rooms; Centralized UPS power supply is suitable for some large computer network rooms requiring long support time.

The power supply mode and capacity of UPS shall be determined according to the needs of Party A. The statistics of centralized UPS power supply capacity shall be closely coordinated by the designer and the owner, and the conversion efficiency of the selected UPS products shall be considered. Especially when the power is large, the conversion efficiency of UPS is very important. High efficiency can save the cost of initial investment and long-term energy loss.

The service life of the battery is closely related to the ambient temperature. When the battery is at a low temperature, the zinc plate in the battery is easy to pulverize, lose the power storage performance and cause permanent damage; When the temperature is too high, the capacity of the battery will also decrease, and permanent damage will be caused in serious cases. According to the technical specifications of the battery manufacturer, the best service temperature of the battery is 2 ~ 25 ℃, which can prolong the service life of the battery.
