Round-trip efficiency, on the other hand, represents the percentage of energy taken from the grid that is fed back into the grid. According to a common industry standard, a BESS is considered to have reached the end of its service life when its actual charging capacity falls below 80% of the original nominal capacity. Charged batteries lose energy over time, even when they are not used. The self-discharge rate measures the percentage of energy lost within a certain period (usually 1 month) and under certain conditions (usually 20. This figure refers to the voltage a battery can be charged and discharged with safely. The voltage range of an accumulator largely.
