6 FAQs about [Battery cumulative charge]
What is cumulative charge-throughput?
Cumulative charge-throughput is a convenient input variable, as it can be easily measured in real-world systems, inherently incorporates the impact of the magnitude of the current on the degradation rate, and does not require a definition of the cycle count that is consistent between varied charge/discharge protocols or dynamic tests.
