In critical sectors such as data centers, communication base stations, and rail transportation, UPS power supply systems are the core of ensuring continuous equipment operation, while batteries are the "last line of defense" for the entire power supply system. A battery failure can paralyze the entire system, causing incalculable losses.
Battery Failure: A Hidden Time Bomb in the System
Statistics show that almost all battery failures can be detected by an increase in the internal resistance of individual cells. According to the IEEE 1188-1996 standard, when the battery's internal resistance increases to 125%-130% of the baseline value, the corresponding battery capacity will drop to 80%, which is the standard line for judging battery failure in the battery industry.
The main causes of battery failure include: passivation of active materials due to long-term float charging, drying of electrolyte, and corrosion and deformation of plates. These factors will directly lead to an increase in battery internal resistance and a decrease in capacity.
With increasingly stringent industry standards, intelligent monitoring is imperative.
The implementation of standards such as GB50174-2017 Design Specification for Computer Rooms of Electronic Information Systems, ANSI/TIA-942 Design and Planning Requirements for Communication Data Centers, and IEEE-1491 Guidelines for the Selection and Use of Battery Monitoring Equipment has placed higher demands on battery monitoring.
In particular, ANSI/TIA-942 Level 4 data center standards explicitly stipulate that the temperature, voltage, and internal resistance of individual batteries must be automatically detected. Battery internal resistance, as a primary parameter indicating battery capacity and health status, along with auxiliary parameters such as voltage and current, becomes crucial for battery monitoring.
