lifetime throughput

Battery lifetime throughput refers to the total amount of energy a battery can store and release over its entire lifespan. It's a key metric for understanding a battery's durability and total capacity for work.

  • Throughputs vs. Cycle Life: Traditionally, battery life is measured in cycles (charges and discharges). Throughput goes beyond cycles and considers the total energy a battery can deliver, accounting for factors like efficiency losses during charging and discharging.

  • Impact on Battery Choice: Throughput helps compare batteries for different applications. A higher throughput for the same capacity indicates a longer-lasting battery, making it ideal for scenarios needing frequent charging and discharging, like solar energy storage.

  • Units and Calculations: Throughput is typically measured in kilowatt-hours (kWh) or megawatt-hours (MWh). While the exact calculation can vary, it factors in the battery's initial capacity, degradation over time, and efficiency during charging/discharging cycles.
