6 FAQs about [Will a constant current power supply damage the battery ]
How does a power supply provide a constant current?
As you can see the power supply will try to provide a constant current by reducing the output voltage. Characteristics of Constant Current Source: Fixed Output Current: The current supplied by a CC source remains constant. Varying Voltage: The voltage adjusts based on the resistance or impedance of the load.
Does a power supply keep output voltage constant if there is no load?
Ie. even if there is no load or if the load is at maximum the power supply will keep the output voltage at a constant level. Keep in mind that if the load current is more than that of the ratted maximum the output voltage can collapse. Byt sources with over current protection this won't be an issue.
What happens if a battery voltage increases?
The charging current decreases as the internal battery voltage increases. ●When the charge current reaches the set termination value, charging is continued for a fixed interval then stopped. Example of ROHM’s Charging IC Profile (with Charging Cord Plugged In)
What happens when a battery pack reaches a constant voltage?
As the battery pack reaches the constant voltage setting, the current starts to decrease, until at 66.4 V the current reduces to close to zero, as the pack is fully charged.
What are the characteristics of power supply overcurrent protection?
