What sort of volume/weight dimensions are required for 33kWh of ultra capacitors?

• jonawesomegreen 11y ago
  They are quite large, but in the particular application weight and volume are not a huge concern. All sitting side by side they are about 20 meters long, 3 meters high, and a meter deep. Probably weighs on the order of 15 tonnes.

    Wow, how much capacitance is that?

      16.3 megafarads, assuming typical cell voltage of 2.7v, and total energy of 33kWh: http://www.wolframalpha.com/input/?i=33kWh%2F%282.7v%29**2 http://www.wolframalpha.com/input/?i=33kWh%2F%282.7v%29**2
