Voltage：
Units of measuring electrical current, all batteries are rated in volts DC. (Direct Current). This determines how much energy is needed to power your equipment.
Voltage plateau:（电压平台）
A slow decrease in voltage over a long period of time. As a rule, the plateau extends from the first voltage drop at the start of the discharge to the bend of the curve after which the voltage drops rapidly at the end.
Nominal Voltage（标称电压）
The voltage of a battery, as specified by the manufacturer, discharging at a specified rate and temperature.
Working voltage（工作电压）
The working voltage of a cell or battery begins at its electrical connections as soon as an electrical consumer is connected to it.
Discharging voltage, average voltage (放电电压)
The average discharging voltage is the average value of the discharging voltage during the entire discharging process with a related discharging current.
Open circuit voltage (OCV开路电压)
The voltage of a battery when there is no current flowing.
Closed-Circuit Voltage (CCV闭路电压)
The potential or voltage of a battery when it is discharging or charging.
State of charge:
The rate of charge capacity vs. whole capacity.
Initial voltage（起始电压）
A battery＇s initial voltage is the working voltage when discharging begins.
End-point voltage (End voltage, Cutoff voltage, Final voltage)截止电压
Specified closed circuit voltage at which a service output test is terminated.
End-of-discharge voltage
The battery voltage when discharge is terminated.
End-of-charge voltage
The battery voltage when charge is terminated.
Cutoff voltage (V)
The battery voltage at which charge or discharge is terminated.
