Hello Martin,

I have received product data from Blusky Energy, which by the way is a saltwater battery and not a flow battery.

The following is the battery data:

  • Cell Voltage = 1,5V
  • No of Cells in serial = 32
  • Internal resistance = approx. 350mOhm
  • Self-Discharge = 3%
  • DOD @ 80% = 5500

 Discharge Table:

  • 10 hours = approx. 53,1Ah (discharge current = ~5A)
  • 5 hours = approx. 46,6Ah (discharge current = ~9,2A)
  • 1 hours and less not possible (to high discharge current, max. = 20A)

1. Is it ok to use the Vented Type for both saltwater and Redox flow batteries?

Hello Anders,

we checked several data sheets from saltwater battery manufacturers to fit our simulation model. Due to the lack of sufficient data we didn't implement a discretely defined model yet. Since saltwater batteries tend to show a similar behaviour as lead-acid batteries (voltage), it is possible to approximate them energetically at least using lead-acid batteries.

It is possible to substitute both saltwater and redox-flow batteries using the lead-acid model considering the data you named above. Being able to compare simulation results to measured data is recommended

Luckily we have access to measured data of one redox-flow battery in the field, so it seems possible to generate a discrete model in the future. So far I'm disillusioned by the energy efficiency and I strongly recommend to ask the manufacturer for measured data preventing you from overrating redox-flow model substitutes**.

If you have further questions feel free to ask!

Best regards!



**It is possible to regard losses due to hydraulic technics via raising the self-discharge factor.
