6 FAQs about [Does the voltage of the energy storage battery change when it is discharged ]

What happens when a battery is discharged?

Among the discharge phenomena so far overlooked is the voltage recovery effect of batteries (a.k.a. voltage rebound/relaxation), where battery power appears to spontaneously surge, even after readings of full discharge in a circuit.

What is the difference between charging voltage and discharging voltage?

Charging voltage refers to the voltage applied to a battery to recharge it. It is typically higher than the battery’s nominal voltage, as the battery must overcome internal resistance and the potential to store more energy. Discharging voltage, on the other hand, is the voltage that a battery provides while it is supplying power to a device.

What happens when a battery is removed from a circuit?

The phenomenon of voltage increase after the battery is removed from a circuit is well documented in other contexts and is called “voltage rebound” in electrical engineering and “voltage relaxation” in electrochemistry. For simplicity, it will be called “voltage recovery” in this work.

Does battery voltage change during lifecycle?

Yes, the battery voltage changes throughout its lifecycle, most notably during charging and discharging. During Discharge: As a battery discharges, its voltage gradually decreases.

When should a battery discharge be stopped?

Theoretically, the discharge may be continued until the voltage drops to zero, but practically, the discharge should be stopped when the voltage of each cell has dropped to 1.7 (on low discharge rates).

What happens if a battery is kept out of the electrolyte solution?

Once voltage remained constant, the battery was kept out of the electrolyte solution and the voltage was monitored further as the open circuit voltage (E OCV), corresponding to the potential difference between the poles and the energy remaining in the battery.
