Background of the programme

The safety and reliability of uninterruptible power supply (UPS) is an important condition to ensure the normal operation of the power supply system of equipment in the computer room, and the battery pack, as the last guarantee of power supply, is undoubtedly the last insurance in the power supply. In the current practical application, improving the safety and reliability of battery pack operation, reducing or eliminating the accident rate of battery pack, and improving the reliability of UPS power supply safety operation are the top priorities of computer room operation and maintenance.

At the same time, the maintenance and management of batteries has always been a tricky problem for most enterprises. In particular, there are a number of unattended UPS applications, such as base stations, bank outlets, etc., which adopt the traditional mode of manual inspection and manual discharge, which is time-consuming and laborious, and difficult to manage. The remote charging and discharging management system of Zonghengtong battery completely solves the above problems.

Solution introduction

According to the characteristics of UPS power supply, a solution is developed to comprehensively evaluate the health state of the battery by monitoring the consistency of the voltage and internal resistance of the battery in an online way, and combining the temperature rise of the battery pole. The battery monitoring system is mainly composed of a battery monitoring unit, a single detection module, and a Hall sensor:

For the remote discharge maintenance of the battery, it is realized through the "Zonghengtong UPS intelligent discharge instrument", which is connected in series to the UPS power supply line to realize the remote charging and discharging management of UPS, and this product mainly supports single-phase or three-phase UPS (30KVA and below) remote manual discharge, local manual discharge and automatic control discharge operation UPS monitoring and other functions.

Program features:

1. Modular installation and bus ring connection: the Zonghengtong battery monitoring scheme uses a collection module for each battery, and the module is attached to the surface of the battery, with few connections, short distance, and convenient installation and expansion. By using the bus ring deployment, the communication link is closed-loop, and the link is super stable.

2. Real-time monitoring of the built-in temperature, voltage and resistance of the single battery: the Zonghengtong online battery monitoring scheme can be monitored online 24 hours a day, monitoring the working temperature of each battery and the ambient temperature of the battery room, as an auxiliary basis for the evaluation of the state of the battery pack, and at the same time monitoring the changes in internal resistance in real time and monitoring the voltage changes of each battery.

3. Real-time acquisition of battery pack working data: the linear battery monitoring scheme can monitor the discharge residual capacity of the battery pack, evaluate the UPS backup working time, and monitor the average charge, floating charge and discharge current of the battery pack.

4. Battery pack data analysis function: through the comparison of the charging and discharging data of the battery and the analysis of the attenuation curve of the battery, the health of the battery can be approximated.

5. Support a variety of discharge control functions: support single-phase or three-phase UPS remote manual discharge, local manual discharge and automatic control discharge operation UPS monitoring and other functions.

6. The unified platform is easy to use: the system can be integrated into the vertical and horizontal communication dynamic ring monitoring system, and one platform truly realizes the function of "monitoring and control", which greatly improves maintenance efficiency and reduces maintenance costs.
