Can igann predict the remaining energy of energy storage batteries?
To address the challenges associated with energy state estimation under dynamic operating conditions, this study proposes a method for predicting the remaining available energy of energy storage batteries based on an interpretable generalized additive neural network (IGANN).
What is remaining energy in a battery?
The traditional definition of the remaining energy is the amount of energy a battery can release from its current state until the state of charge (SOC) reaches zero. However, in practical operations of energy storage stations, to ensure battery safety and prolong its lifespan, the battery is typically not fully discharged.
How do battery state estimations interact with each other?
3) Joint Estimation: Battery state estimations are coupled and they interact with each other. For example, the accuracy of SOC estimation is affected by SOH estimation, such as capacity and resistance. While these parameters used for SOH estimation are limited by the accuracy of SOC estimation.
When a battery is not fully discharged?
However, in practical operations of energy storage stations, to ensure battery safety and prolong its lifespan, the battery is typically not fully discharged. An important condition for determining the end of discharge is when the lowest voltage among the battery cells reaches the prescribed minimum discharge voltage, U min.
Why does battery voltage vary during a discharge cycle?
In the actual operation of the energy storage station, due to the unknown operating conditions of the battery from the previous cycle, which may involve varying durations of idle time, charging, or discharging, the polarization level of the battery can vary significantly. As a result, the voltage at the start of each discharge cycle is different.
Can incomplete charging data accurately estimate battery Soh?
The validation results highlight that the proposed method can accurately estimate SOH through incomplete charging data. In , the authors first build an approximate battery SOH degradation model for real vehicle operation.
