Battery Model
Relaxation Model:
- Real-life battery exhibit a phenomenon called “relaxation”.(Fuller 94, Linden 95, Chiasserini 99)
- When battery discharge rate is high, diffusion rate of active ingredients through the electrode & electrolyte falls behind. If high discharge is sustained, the battery reaches its end even if the active materials are still available.
- However, if discharge current is either cut-off or reduced during the discharge, active materials catches up with depletion of the materials. It gives battery to recover the capacity lost at high discharge rate.
- An analytical model has been used for SensorSim
