Dive into the intricate world of energy storage batteries! Explore key parameters such as capacity, voltage, energy density, and cycle life that determine battery performance. Understand how these factors interrelate and influence practical applications in residential energy storage, electric vehicles, and grid solutions.
Constant voltage charge is the battery charge operation in which the battery voltage is held constant and where the power and current freely adjust. (‘ CV charging ’) 3.2.3. Constant voltage discharge mode

Energy storage capacity of a cell or battery can be calculated by using (actual charge) capacity C and battery open-circuit voltage vBat,OCV (t) between full and empty state: (10) E C = ∫ q (S O C = 0 %) q (S O C = 100 %) v B a t, O C V (q) d q Energy storage capacity is usually expressed in kilo watt hours (kWh).
The other way round stored electric charge of a battery can be expressed by using the SOC value: (6) q (S O C) = S O C C Since the value of capacity changes during lifetime due to battery aging, an index of SOC can specify the capacity C, which is the reference for SOC value.
Thereby the battery is assumed sufficiently charged according to ‘ restored energy time ’ (see below). According to the reference temperature of the battery is usually 25 °C. Additionally the temperature of the battery can be measured in order to derive a necessary adjustment to the expected stored energy time.
