Dual-Layer Capacitor Batteries for Intelligent UPS System

Sept. 13, 2012
These capacitor-based dual-layer batteries for the QUINT UPS-IQ line, like the lithium-ion battery introduced earlier this year, have a longer lifespan and wider temperature range than the UPS's original valve-regulated lead acid (VRLA) battery.

The capacitor-based energy storage can operate between -20 and 60 °C and has an operational lifespan of up to 20 years depending on ambient conditions. The original VRLA battery, by contrast, is rated for use between temperatures of 0 to 40 °C before experiencing severe derating and operational issues. Using the UPS with the capacitor battery reduces the need to replace the batteries frequently, which can be challenging in harsh conditions. Users can gain additional visibility into the performance behavior of the capacitors, including state of charge, which indicates the remaining backup time and level of charge on the battery; state of health, which indicates the remaining service life of the battery module(s) and state of function, which indicates the capacity of the battery module(s).
