In the industry, battery capacity is expressed as Ah (ampere-hours). However, electric charge capacity, which is the value normally specified on a battery label, is different. The capacity of a battery expressed as the amount of electric energy stored in it is more important.
Battery capacity is often measured in Amp-hours (Ah), which indicates how much current a battery can deliver over a specific period. Voltage, on the other hand, represents the electrical potential difference that drives current through a circuit. Together, these two metrics are crucial for evaluating battery performance in various applications.
The term 'battery capacity' can be confusing because it is sometimes used to refer to the electric charge stored in a battery, while at other times it denotes the amount of electric energy contained in a battery. It is crucial to distinguish between the two, as they represent different electrical quantities.
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
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.
Understanding Voltage Voltage is the measure of electrical potential difference between two points in a circuit. It influences how much current flows from the battery to the load. Higher voltage batteries can deliver more power to devices, which is essential for applications requiring high energy output.
