3. Internal resistance and short circuit current
The internal resistance of the battery is a dynamic nonlinear parameter that is continuously
changed along with the temperature and discharge state. The internal resistance is the lowest
when battery is fully charged. The table 2-1 shows the internal resistance and short circuit
current in fully charged state
