A battery cycle is a complete charge and discharge cycle, so the number of cycles is actually a charge cycle calculation method. The battery discharge to 50% charge twice is counted as a discharge cycle, and the discharge cycle is counted as the cycle number. When the battery reaches a full charge cycle, the number of battery cycle will be +1.
The number of cycles is the total number of full and partial discharge cycles that this number represents over the entire battery life. A battery cycle is a complete charge and discharge cycle, so the number of cycles is actually a charge cycle calculation method.
In this paper, during the analyses when each battery charging data set and discharging data set reaches to a maximum level of 100%, the half charge and discharge cycles are incremented, independently. A full equivalent cycle is determined as average of battery charge and discharge cycles for the given period of time.
Generally, battery life is calculated based on the current rating in Milliampere (mA) and the capacity of the battery in Milliampere Hours (mAh). The battery life can be calculated from the input current rating of the battery and the load current of the circuit. Battery life will be high when the load current is low and vice versa.
A one-charge cycle means that the battery has been fully charged once, but it does not necessarily mean that only one charge has been made. 2.How many cycles does a battery have? Generally, Lithium-ion batteries have a long battery cycle life of up to 4,000 cycles, which far beyond regular batteries.
In this paper, a fast battery cycle counting method is proposed for grid-tied BESS, that is subjected to microcycles, to approximate the number of equivalent battery full charge-discharge cycles. The proposed fast cycle counting method is demonstrated for a BESS delivering EFR service to the grid.
In this estimation method it is key to know the initial state of charge of the battery (this value is normally updated when the battery is completely charged) and to measure the current accurately.
