Hi,
I am trying to build a lithium ion battery model using Coefficient Form PDE equations in Mathematics module, instead of using the in-built Lithium Ion Battery module.
For this, I want to implement a charge-discharge cycling boundary condition which involves 3 steps.
Step 1: Charge at a constant current (I_cell) upto a maximum cell cut-off voltage (V_max). Step 2: Then, charge at a constant voltage (V_max) until the cell current drops to a small value (I_min). Step 3: Next, discharge at constant current (-I_cell) until the cell voltage drops to a lower cut-off value (V_min). Repeat this sequence of steps for a given number of cycles.
It can easily be done using the in-built charge-discharge cycling boundary condition in the lithium ion battery module. However, I would like to implement the same BC in my model which is based on Mathematics module.
Can someone suggest me the approaches to acheive this?
Thanks in advance! Ganesh
