Battery degradation refers to the gradual decline in the ability of a battery to store and deliver energy. This inevitable process can result in reduced energy capacity, range, power, and overall efficiency of your device or vehicle. The battery pack in an all-electric vehicle is designed to last the lifetime of the vehicle.
With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components . Mechanical stress resulting from the expansion and contraction of electrode materials, particularly in the anode, can lead to structural damage and decreased capacity .
Thus, it largely reduces the time and labor for battery pack investigation. The predicted capacity trends of the battery cells connected in the battery pack accurately reflect the actual degradation of each battery cell, which can reveal the weakest cell for maintenance in advance.
Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.
Battery deterioration is predicted using a machine learning approach called support vector machines (SVM). SVM models anticipate the degree of battery degradation or estimate the battery’s remaining usable life by using historical data and battery performance characteristics, including voltage, current, temperature, and cycle count .
See further details here. Batteries play a crucial role in the domain of energy storage systems and electric vehicles by enabling energy resilience, promoting renewable integration, and driving the advancement of eco-friendly mobility. However, the degradation of batteries over time remains a significant challenge.

In addition, the battery ECU monitors the SOC, and if the difference between the maximum and minimum SOC values exceeds the standard, it determines that malfunction has occurred. When either of the malfunction detection conditions is met, the battery ECU illuminates the MIL and sets a DTC. P0A7F Code - Hybrid Battery Pack Deterioration
