Run thousands of simulations in the cloud using our Powermap tool! How does it work?

• We find the maximum continuous Pulse Power the cell can deliver using our 2RC pair Equivalent Circuit Model (ECM) with coupled lumped thermal model. The parameters for the ECM come from our proprietary testing and modelling methods.
• We run thousands of cloud ECM simulations using our proprietary optimisation algorithm, finding the maximum continuous Pulse Power the cell can provide whilst satisfying the following optimisation constraints:
  • Cell voltage must be within datasheet limits
  • Cell pulse duration= User-specified pulse duration
  • Cell temperature ≤ User-specified temperature limit
  • Cell current ≤ User-specified current limit

The result is a map showing the maximum continuous Pulse Power the cell can deliver over a specified pulse duration, for any combination of initial temperature and initial SoC.

Note that Pulse Power is only given in watts for pro users.

🔧 You can configure the Pulse Power optimisation by choosing:

• Temperature limit - The maximum temperature the cell can reach [°C]
• Pulse duration - The duration for which the cell must be able to provide continuous power for [s]
• Ambient temperature - The temperature heat is rejected to via the lumped thermal model [°C]
• Current limit - The maximum current the cell can handle to remain safe [A]
• Heat transfer coefficient - the average convective heat transfer coefficient on all surfaces of the cell [W/(m^2.K)]

🔍 How accurate is the output?

• Our models are typically very accurate at <30 mV RMS
• We estimate that using an ECM in this way results in a Pulse Power estimation of +/- 20%
