Product Parameters

Nominal voltage

An appropriate approximate voltage used to identify or characterize a battery or an electrochemical system.
Charge voltage

The voltage applied by an external power source across the two terminals of the battery during charging.
Working voltage

The voltage across the positive and negative terminals of the battery during discharge at the operating current.
Over voltage

"Over voltage is a state where the battery voltage exceeds the manufacturer's/supplier's rated values or specified conditions. Over voltage can disrupt the normal functioning of the battery and/or lead to hazardous incidents.Note: When discussing electrodes, it is referred to as overpotential."
Discharge voltage

The voltage between the two terminals of the battery during discharge.
End-of-charge voltage

The maximum voltage allowed during the normal charging of a battery cell, module, battery pack, or system.
End-of-discharge voltage

The minimum voltage allowed during the normal discharge of a battery cell, module, battery pack, or system.
Open-circuit voltage

The difference in potential between the positive electrode and the negative electrode under a no-load condition.
Shell voltage

Refers to the voltage between the positive and negative terminals of a metal-cased battery with respect to the battery's outer shell. Generally, this is determined by the battery manufacturer based on their own manufacturing processes and sets the qualified standards.
Dc impedance

The resistance calculated as the ratio of the change in battery voltage over a short period of time to the corresponding discharge current under direct current (DC) operating conditions.Note: DC impedance is typically expressed in milliohms (mΩ).
Ac impedance

Refers to the battery's alternating current impedance measured at a specific alternating current frequency, typically the alternating current impedance of the battery at 1 kHz.Note: Alternating current impedance is usually expressed in milliohms (mΩ).
Charge

The process in which an external circuit provides electrical energy to the battery, causing chemical changes within the battery, thereby converting electrical energy into chemical energy and storing it.
