BACS

Battery analysis and care system

BACS: the 3rd generation of the battery management system

Monitoring, regulation and alarm system for lead-acid batteries. Ensuring full battery system operability, preventing unexpected or unnoticed faults caused by defective batteries, extending the lifetime of the batteries and helping to presence system reliabitily. The 3rd generation of the Battery Analysis and Care System.

 

BACS, is a network-integrated battery monitoring and management system. It regularly checks the internal resistance, temperature and voltage of each individual battery. It is also possible to adjust the charging voltage of each battery and manage environmental measurements (temperature, humidity, hydrogen gas content) and applications (UPS systems, rectifiers, DC systems, inverters and other devices). This ensures that the batteries always remain in optimum operating conditions. The system’s ability to constantly monitor and individually control the charging voltages for each battery ensures battery availability at all times - making the socalled Achilles heel of UPS systems (or any other power device) a thing of the past.

 

BACS is suitable for all lead-based (AGM, gel, sealed and open leadacid), nickel-based and lithium-ion batteries.

Technology

  • The system is designed to monitor and control batteries individually or in battery blocks, providing a symmetrical charging process. . Individual voltage regulation: even distribution of the voltage supplied by the charger.
  • Protection against any unexpected individual overcharging (gassing), drying out or full discharge of batteries.
  • Sulphation problems are prevented through visualisation and communication of sulphation levels.
  • Protection for nearby batteries against charging voltage faults in one battery.
  • Through its equalising system, it ensures optimum capacity for battery systems throughout their lifetimes.
  • Intensive and comprehensive analysis in one battery of the power supply system. · Available for sealed lead batteries (2, 6, 12 and 16 V) and Ni-Cd, Ni- MH, lithium-ion batteries (1.2 to 3 V) with capacities ranging from 7 Ah to 5000 Ah.
