How do you calculate energy stored in a super capacitor?

For instance, if you have a super capacitor with an energy density of 5 Wh/kg and a mass of 2 kg, the energy stored in the super capacitor is calculated as: \ [ ES = 5 \times 2 \times 3600 = 36000 \text { Joules} \]

How much power does a supercapacitor produce?

Supercapacitors usually yield a lower working voltage in the range 2,5 - 20V. As of 2010 larger double-layer capacitors have capacities up to 5,000 farads. Also in 2010, the highest available supercapacitor energy density is 30 Wh/kg, lower than rapid-charging lithium-titanate batteries.

Does Eaton have a calculator containing all supercapacitors?

To assist in determining the number of modules in series and those subsequent strings in parallel, Eaton has developed a calculator tool containing all supercapacitors .

What is a capacitor capacity & ESR?

Capacity: The Capacity in Farad of the capacitor. Max. voltage: The maximum Voltage the Capacitor accepts. Normal ultracapacitor have values between about 2.3V and 2.85V. This value is for warning, if your design exceeds this max. voltage. ESR: The internal series resistor of the capacitor. This value is very important, in particular at high loads.

How do I choose the best ultracapacitor?

Take into account the leakage current and possible power loss in load-balancing circuits, which may be relevant in very low power applications. Calculate with different ultracapacitor types and different voltage ranges to find the most efficient and most cost-effective design which meets your requirements.
