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 Ares series battery is fully charged. The table 2 ‐ 3 shows the internal resistance and short
circuit current of Narada battery in fully charged state according to IEC60896. If the voltage
decrease 0V due to short circuit that can damage the battery.
