6 FAQs about [Battery pack discharge end voltage difference]

What happens when a battery is charged or discharged?

Applying a charge or discharge places the battery into the closed circuit voltage (CCV) condition. Charging raises the voltage and discharging lowers it, simulating a rubber band effect. The voltage behavior under a load and charge is governed by the current flow and the internal battery resistance.

What is the difference between deep discharge and terminal voltage?

Depth of Discharge (DOD) (%) – The percentage of battery capacity that has been discharged expressed as a percentage of maximum capacity. A discharge to at least 80 % DOD is referred to as a deep discharge. Terminal Voltage (V) – The voltage between the battery terminals with load applied.
