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).
Should a supercapacitor be used at a low temperature?
As a result, it is recommended to use the supercapacitor at the lowest temperature possible to decrease internal degradation and ESR increase. If this is not possible, decreasing the applied voltage to the supercapacitor will assist in offsetting the negative effect of the high temperature.
How does temperature affect the lifetime of a supercapacitor?
Temperature in combination with voltage can affect the lifetime of a supercapacitor. In general, raising the ambient temperature by 10 °C will decrease the lifetime of a supercapacitor by a factor of two. As a result, it is recommended to use the supercapacitor at the lowest temperature possible to decrease internal degradation and ESR increase.
How cold can a supercapacitor operate?
Supercapacitors can operate without relying on chemical reactions, so they can operate over a wide range of temperatures. On the high side, they can operate up to 85°C, and without risk of thermal runaway. On the low side, they can deliver power (with slightly increased resistive losses) as cold as -
How many volts can a supercapacitor handle?
Individual supercapacitors are limited to 2.5 V (P Series reaches 5 V using two supercapacitors in series). As many applications require higher voltages, supercapacitors can be configured in series to increase the working voltage.
What is the maximum RMS current in a supercapacitor?
Fig 6 since they are larger cans. From Fig 6, the maximum RMS current i an application can be calculated. For example, if the ambient temperature is 40C, and the maximum operating temperature for the supercapacitor is 85C, then the maximum RMS current for a 10F supercapacitor should be limited to 5.5A, which ca
