Schematic diagram of battery cycle life prediction based on discharge voltage curves. The colors of the discharge voltage curves indicate that they belong to different cycles, and the colors of the curves in the feature extraction and selection box suggest that their values change as the cycle number increases.
The discharge curve is a plot of voltage against percentage of capacity discharged. A flat discharge curve is desirable as this means that the voltage remains constant as the battery is used up. 4) Capacity The theoretical capacity of a battery is the quantity of electricity involved in the electro-chemical reaction.
In Fig. 1 (a), (b), and (c), from the 10th cycle to the 100th cycle the voltage–capacity discharge curves shift to the left. Upon examining the voltage-capacity discharge curves of the 100th and 10th cycles, it appears that the larger the shift between the two curves, the shorter the battery's cycle life.
The HIs are extracted from lithium-ion batteries voltage-capacity discharge curves, since these curves are easy to measure and strongly correlate to battery cycle life. Taking into account the nonlinearity of batteries cycle life, a support vector machine (SVM) that is capable of strong generalization is used to predict cycle life.
The slope of the lithium battery discharge curve can reflect the discharge performance of the battery. A flatter lithium battery discharge curve usually indicates that the lithium battery has better discharge stability and can provide stable energy output.
Metaphorical Explanation Think of boiling water: When you turn up the heat on a stove, water heats up faster. Similarly, at higher discharge rates, the battery heats up more quickly. The temperature rise curve captures this heating process, acting like a thermometer for the battery’s performance.
