Battery Management System

JUNXY-TA CELLCHECK Intelligent Battery Monitoring System
---Internal Resistance, Voltage and Temperature Measurements

JUNXY-TA intelligent battery monitoring system is designed specifically for single cell. It combines the advanced technology with patented for the most thorough stationary battery health analysis in the industries of UPS, telecommunications, battery supplied applications, utilities, fire & safety system, remote monitoring and many more.

  •  Continuous 24/7 on-line monitoring
  • Each CELLCHECK tests only one cell, monitoring internal resistance, voltage and temperature
  • Software is available to collect data from CELLCHECK
  • Serial port with Optical isolation, meet MODBUS protocol, easy to be accessed by UPS controller
  • Easy to install without specialized training

  • Full resistance, battery temperature and voltage monitoring for comprehensive battery state of health analysis
  • String current and ambient temperature monitoring(need TC module)
  • Automatic analysis of battery monitoring data, find out the batteries that need replacement or maintenance (need CM module)
  • With a big storage space to save history data
  • Lights on panel flash when alarms rise up which also can be read over through serial bus
  • All operating parameters can be set over through serial bus
  • A software base on PC is available to manage multiple strings, check real-time alarm and historical data
