One of our most popular blog posts was on the valuable insights hidden in raw time-series data. Once such insight is differential capacity analysis, or dQ/dV.
Differential capacity (dQ/dV) analysis allows you to observe battery degradation, failure mechanisms and changes in chemistry in much greater detail than can be observed using aggregate statistics like capacity, energy and efficiency per cycle. Conceptually, dQ/dV describes the incremental capacity going into or out of a device over a given voltage increment. Differential capacity can be derived from raw time series current and voltage data, or accessed directly using a Battery Intelligence platform such as Voltaiq.
