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.
Authors have claimed that the degradation mechanism of lithium-ion batteries affected anode, cathode and other battery structures, which are influenced by some external factors such as temperature. However, the effect of battery degradation on EV and energy storage system has not been taken into consideration.
Environmental Factors: The environment in which a battery operates can significantly influence its rate of degradation. Temperature extremes, both hot and cold, can be particularly damaging. At extreme low temperatures, the battery may seize to function temporarily.
Time: Batteries naturally degrade over time, even when they are not in use. This type of degradation is often referred to as calendar degradation. It is influenced by the state of charge at which the battery is kept, with high states of charge generally leading to faster battery degradation.
The depth of discharge, or how much the battery is drained during each cycle, can impact the rate of degradation. Deep discharges and high charge rates can accelerate degradation. Extreme temperatures, both hot and cold, can accelerate battery degradation.
Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
