Phoenix Contact Dual-Layer Capacitor Batteries for QUINT UPS-IQ

Valve-regulated lead acid (VRLA) batteries have been the standard battery chemistry for battery back-up systems for years. They have been proven to be a reliable solution for industrial applications. However, they have a crippling limitation: temperature. Most VRLA batteries commonly used have an operational temperature range of -0 to 40 C before experiencing severe derating and operational issues.

This is one of the reasons Phoenix Contact has introduced capacitor-based energy storage. This battery has a wider operational temperature range of -20 to 60 C, allowing battery back-up solutions to be placed in more harsh environments without having to worry about frequent replacements of the battery.

The capacitor technology also allows a back-up system to have a longer operational lifespan before the user has to replace the batteries. This capacitor-based energy storage has an operational life of up to 20 years based upon the ambient conditions – nearly ten times that of the standard VRLA battery.

When used with the QUINT UPS-IQ family of products, users can gain additional visibility into the performance behavior of the capacitors such as:

  • State of Charge (SOC): Indicates the remaining backup time and level of charge on the battery. Customers will be able to see the amount of available time left at a quick glance.
  • State of Health (SOH): Indicates the remaining service life of the battery module(s). The history of the battery module(s) is recorded and an indication is provided of when the battery needs to be replaced before it becomes a concern.
  • State of Function (SOF): Indicates the capacity of the battery module(s). The available capacity of the battery is provided giving indication as to how well the battery is accepting the charge and if the full capacity is still available.
