Introduction

This video explains the factors influencing battery cycle life. Jimmy from Discover Battery's business development team discusses four key variables affecting cycle life: temperature, charging/discharging duration and current, depth of discharge, and remaining capacity. He also highlights the importance of understanding international test standards and their varying parameters.

Key Takeaways

• Temperature: Cooler temperatures extend battery cycle life compared to higher temperatures.
• Charging/Discharging Duration and Current: Longer or shorter charge/discharge times and varying current levels impact cycle life.
• Depth of Discharge (DoD): Shallower discharges (e.g., 50% DoD) significantly increase cycle life compared to deeper discharges (e.g., 100% DoD).
• Remaining Capacity: End-of-life definitions vary depending on the test standard, typically ranging from 50% to 80% of the original capacity.
• Test Standards: Different international standards (e.g., IEC 6254-1, IEC 60896-11, JIS D 2185) define varying parameters for charging, discharging, and end-of-life criteria, leading to different cycle life results for the same battery.
