All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
Results and Discussion This research shows that the most used control method for charging and discharging lead-acid batteries in renewable energy systems with battery energy storage is that of CC–CV. However, this control method requires a long time to charge the battery.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
Despite the fact that constant-current–constant-voltage (CC–CV) is the most used control method for battery charging and discharging, other methods such as FLC or MPC have shown better performances.
The charge control method’s efficiency will depend on the amount of current used for the charging process, the level of the oscillations in the charging current, the charging voltage levels, the charging time, and the fluctuations in the temperature during the charging .
During the initial stage of charging, the charge current is high. As the battery voltage reaches the charger’s voltage set limit, the charge current decreases . This type of control is used in applications that require extended charging periods to reach full charge.
BU-402: What Is C-rate?
C-rate is defined as the charge / discharge current divided by the nominally rated battery capacity. For example, a 5,000 mA charge on a 2,500 mAh rated battery would be a 2C rate. A 2,500 mA charge on the same battery would be a 1C rate and would theoretically fully charge the battery in 1 hour (assuming 100% charge efficiency). The capacity ...

In electricity, the discharge rate is usually expressed in the following 2 ways. (1) Time rate: It is the discharge rate expressed in terms of discharge time, i.e. the time experienced by a certain current discharge to the specified termination voltage ch as C/5, C/10, C/20 (2) C rate: the ratio of the battery discharge current relative to the rated capacity, that is, times the rate.

How Charging and Discharging Rate Affect Battery Performance
The charging rate tells us how fast a battery can store energy. The C-rate defines the time it takes to fully charge the battery: 1C means the battery charges completely in one hour. 0.5C means it takes two hours to charge. 2C indicates the battery charges in just 30 minutes. For example, if you have a 2,000mAh battery: At 1C, it charges at 2 ...
