Problem with table-based battery, Simscape, simulink

Table-based Battery, Simscape, Simulink

Problem:

The start values for the SOC, V0 and R0 is 1x4 data points. Everytime we try to make it 1x5 or higher we get the message:

"Length of Terminal resistance, R0(SOC) must be equal to length of Vector of state-of-charge values, SOC."

Even thought the vectors are the same length.

How can we get more data points into the battery?

Setup:

• Temperature dependent tables: No - do not tabulate over temperature
• Current directionality: Enabled
• Self-discharge: disabled
• Extrapolation method for all tables: Nearst
• Dynamics: None

Thank you in advance for your time

I am having this exact issue; it only appears when current directionality is enabled.

I have disabled this in my model for now, but would like to be able to enable it in the future. I greatly appreciate any updates to Benedikte's question.

Any luck with this issue?

A = [-b/J K/J

-K/L -R/L];

B = [0

1/L];

C = [1 0];

D = 0;

motor_ss = ss(A,B,C,D)
