The main factors influencing the degradation of battery capacity over time can be categorized into operational, environmental, and temporal factors. Here is a breakdown of these factors:
Operational Factors
- Charge/Discharge Cycles: Each cycle contributes to battery wear and tear. Deep discharges (completely draining the battery) stress the battery more than shallow discharges, accelerating degradation.
- Charge and Discharge Rates: High charge and discharge rates can strain the battery, leading to faster degradation. Moderate charging is generally recommended.
- State of Charge (SoC) and Depth of Discharge (DOD): Maintaining a battery between 20% and 80% SoC can help mitigate degradation.
Environmental Factors
- Temperature Extremes: Both high and low temperatures can harm battery health. High temperatures accelerate chemical reactions within the battery, while low temperatures impede charge acceptance and retention.
- Storage Conditions: Storing batteries in extreme environments can accelerate degradation.
Temporal Factors
- Aging: Batteries naturally lose capacity over time due to irreversible chemical reactions, regardless of usage.
- Manufacturing Quality and Materials: The quality of materials used can impact degradation rates. Impurities or defects can lead to faster degradation.
Understanding and managing these factors can help extend battery life and improve performance. Proper charging practices, temperature management, and software optimizations are recommended strategies to mitigate battery degradation.
