WebApr 11, 2024 · Accurate state-of-health (SOH) estimation is critical to guarantee the safety, efficiency and reliability of battery-powered applications. Most SOH estimation methods focus on the 0-100\\% full state-of-charge (SOC) range that has similar distributions. However, the batteries in real-world applications usually work in the partial SOC range … WebDec 1, 2024 · The method of cross-validation was employed, in which we used two batteries to train the model and used the remaining battery to test the SOH estimation method. For example, in the first experiment, the batteries RW3 and RW4 were used as the training batteries, and the battery RW5 was used as the testing battery. fl lottery headquarters
