To calculate the electric energy stored in a battery, multiply the battery’s charge capacity C (in Ampere-hours) with its voltage V. Since the voltage V is always clearly specified, we know how much that is. And the charge capacity C (in Ampere-hours) is also typically specified.
In 2018, the capacity was 869 MW from 125 plants, capable of storing a maximum of 1,236 MWh of generated electricity. By the end of 2020, the battery storage capacity reached 1,756 MW. At the end of 2021, the capacity grew to 4,588 MW. In 2022, US capacity doubled to 9 GW / 25 GWh.
A car battery has a voltage of 12V, and we can calculate that it stores 720 Wh of energy. Knowing this, we can compare it to other batteries. For instance, a AAA battery, with a voltage of 1.2V, stores 1.2 Wh of energy.
The state of charge influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
For example, if a fully charged battery with a capacity of 100 kWh is discharged at 50 kW, the process takes two hours, and the C-rate is 0.5C or C/2. As a specification of a battery, the C-rate usually indicates the maximum C-rate, meaning that the higher this key figure, the faster the battery can be charged and discharged.
In this way, they contribute to an efficient and sustainable power grid. How battery energy storage systems work Battery energy storage technology is based on a simple but effective principle: during charging, electrical energy is converted into chemical energy and stored in batteries for later use.

$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
