I understand that you are facing difficulty while using a table-based battery in Simscape. It is important to note that the messages you are seeing are not errors but rather warning messages which are being thrown to highlight violation in defined constraints for Terminal voltage. These messages are summarised as follows.
Warning: MYTHESIS_SIMSCAPE1/Battery Equivalent Circuit''Terminal voltage'' must
be greater than or equal to its lower bound defined in ''Terminal voltage
operating range, [Min Max]''.
In Simscape, table-based battery has "Terminal voltage operating range" as one of its parameters which is represented in form of a 1x2 vector. It specifies the lower and upper bounds for the terminal voltage. Have a look at the snapshot attached below for your reference.
These warning messages indicate that the value of the Terminal voltage you are currently using is below the lower bound defined by the "Min" value. To resolve this issue, you should adjust the "Terminal voltage" to a value that is equal to or greater than the defined lower bound. Even though, you have not modified the parameter, please ensure that the value of Terminal voltage is kept above 0 to suppress these warning messages.
I hope this helps.
