How long does a super capacitor last?
The life of supercapacitors will double for every 10°C decrease in temperature or voltage by 0.1V. Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature. L1= Load life rating of the super capacitor (typically 1000 hours at rated temperature).
Can a supercapacitor be operated out of a specified range?
Fig. 1 Example of Derating Temperature and Voltage to Extend Lifetime. Abracon does not recommend operating supercapacitors out of their specified ranges. For example, designing a 0-700C supercapacitor into a system that will experience 850C ambient temperature is not recommended, regardless of whether the temperature increase is temporary.
What is the safe operating temperature of a supercapacitor?
Most supercapacitor manufacturers specify the safe operating temperatures in the range of −40 to 70°C. Chapter 2 presents more treatment of the subject matter on Thermal Considerations for Supercapacitors. They have excellent low temperature performance which can meet the power needs in extreme weather conditions in heavy electrical applications.
What are the thermal considerations for supercapacitors?
The ambient temperatures, where the supercapacitors are deployed, have a major influence particularly at the extremes. Most supercapacitor manufacturers specify the safe operating temperatures in the range of −40 to 70°C. Chapter 2 presents more treatment of the subject matter on Thermal Considerations for Supercapacitors.
Can a 0-700c supercapacitor be used at 850C ambient temperature?
For example, designing a 0-700C supercapacitor into a system that will experience 850C ambient temperature is not recommended, regardless of whether the temperature increase is temporary. The industry has adopted a few standards to help determine the expected life of a supercapacitor based on the materials used and the design of the component.
