Capacity measurement is one of the most common methods to assess battery degradation. By comparing the current capacity of a battery to its original capacity, the extent of degradation can be determined. Capacity measurements are typically conducted through full charge and discharge cycles, monitoring the energy stored and released by the battery.
Voltage measurement is another widely used technique to monitor battery degradation. As a battery degrades, its voltage profile changes, providing insights into its health. By comparing the voltage under load or during charging to the expected voltage for a healthy battery, the extent of degradation can be estimated.
Battery degradation can be described using three tiers of detail. Degradation mechanisms describe the physical and chemical changes that have occurred within the cell. Mechanisms are the most detailed viewpoint of degradation but are also typically the most difficult to observe during battery operation.
Each time a battery goes through a charging and discharging cycle, it undergoes stress that contributes to its 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.
While degradation can't be eliminated entirely, we present a hopeful future for battery longevity through continuous innovation and optimization.
To best manage your batteries for long-term success, look instead for ways to gain more actionable insights, allowing you to pinpoint opportunities to reduce battery degradation and increase the lifespan of your fleet.
