Battery Model
Goal: increase the battery life time
Need to study how different aspects of real battery behavior can affect the energy efficiency of applications
T = C/I, C is capacity in Ah. I is discharge current
Linear Model:
- Linear storage of current. Assumes the maximum capacity is unaffected by discharge rate.
- Allows user to see efficiency of user application by providing how much capacity is consumed. The remaining capacity after td can be expressed as C = C’ - ? I(t)dt integral taken over period t = 0 to td
- It assumes that the I(t) will stay same during the period, if operation mode does not change (radio switching from Tx toRx)
- Remaining capacity is computed when discharge rate is changed
