The green boxes contain values which may be changed.

The software modifies erroneous proposed values.

Step 1: Application energy & power requirements

The first step in sizing supercapacitor energy storage is the determination of the energy requirement, taking into account the following corrections:

• - the voltage is limited to a low value limit because of the electronic requirement (typical Un/2).
• - there are losses in the system

Step 2: Supercapacitor technical properties

This calculation step takes into account the performances of the technology which depends from one manufacturer to the other. Typical values are 2.5 Vdc, 5.3 Wh/kg and 8'566 W/kg.

It considers also that a part of the energy is dissipated inside the component in the internal resistance (cf "RAGONE").

Step 3: Determination of the supercapacitor working voltage

A distribution of 12 application voltages (close to U_n) may be given in the first column

In the second column the corresponding application temperature must be defined

In the third column the duration of each collicitation must be defined in %.

You have to adjust the number of cells in order to get an acceptable lifetime.

Cell Nr in series [1]:  

Expected life duration [Hours]: 1500   [years]: 0.17

Step 4: Energy storage size (based on Garmanage reference technology)
