Battery degradation refers to the gradual reduction in a battery’s capacity over time and through repeated charge/discharge cycles.
This is a natural phenomenon resulting from the wear and tear of the battery’s internal components.
As the battery ages, its ability to store and deliver energy diminishes, leading to a decrease in the Electric Vehicle’s (EV) range. Key factors influencing degradation include: battery age, frequent charge/discharge cycles, extreme State of Charge (SoC) (consistently high or very low), and temperature (both high and very low temperatures accelerate chemical and mechanical wear).
Typically, a quality battery retains about 70-80% of its capacity after 8 to 10 years of use. Advanced technologies, such as thermal management and optimized charging protocols, are being developed to mitigate this process and enhance battery longevity.
