Battery Monitoring System
A system that monitors the condition of lead-acid batteries used in power supply equipment.
This system monitors the condition of lead-acid batteries used in power supply equipment.
By centrally managing a large number of batteries and measuring voltage, internal impedance, and temperature near the battery, it enables early detection and notification of battery abnormalities and deterioration. Remote monitoring is also available, helping to reduce maintenance workloads in remote locations such as isolated islands.
System Configuration
Features
Easy Installation
Wireless communication between wireless sensor units and wireless master units reduces the risk of cable disconnection and simplifies installation by minimizing complex wiring work.
Integration with Customer’s Monitoring Systems
Supports the Modbus/TCP communication protocol, enabling integration with customer’s monitoring systems.
Measurement Data Management and Visualization
An upper-level controller (optional) stores battery measurement data (voltage, internal impedance, temperature near the battery), supports CSV file output, and visualizes data through trend graphs, condition diagnostic displays, and battery reports.
