What happens if a battery discharge rate is high?
The discharge capacity at 4C was 71.59% lower than the standard capacity provided by the battery manufacturer. When the discharge rate was high, the ohmic internal resistance, polarization internal resistance and total internal resistance all decreased with the increase of the discharge rate.
Why does internal resistance increase during discharge?
In general, internal resistance will rise during discharge due to the active materials within the battery being used. However, the rate of change during discharge is not consistent. Battery chemistry, depth of discharge, drain rate and the age of the battery can all impact internal resistance during discharge.
What happens when a battery is discharged?
During discharge, the internal battery resistance decreases, reaches the lowest point at half charge and starts creeping up again (dotted line). Figure 5: Internal resistance in nickel-metal-hydride. Note the higher readings immediately after a full discharge and full charge.
How does discharge rate affect cell total internal resistance?
At high current rates (≥2C), the cell total internal resistance decreases as the discharge rate increases. This is consistent with the results of Chen et al. . The total internal resistance value at the high current rates is smaller than the low current rates.
