- Performance and Discussion
-Charging current depends on the difference in voltages
Assuming constant battery internal resistance, I=(V-Vbatt)/Rbatt
-This design only works with a brushed DC motor where rpm is proportional to voltage, and
torque is proportional to current
-Note: the battery voltage increases with charge.
The voltage of a fully charged battery is often greater than its nominal voltage
-V=IR not applied correctly. A resistor is not needed, however to ensure the battery
doesn't overcharge, the rpm should be limited to the charged voltage of the battery.
