Understanding the Battery SOE (State of Energy) of Lithium-Ion

Battery SOE refers to the ratio between the battery''s remaining available energy and its maximum available energy. It is typically represented as a percentage between 100% (fully charged) and 0% (fully discharged). Tracking SOE allows the BMS to determine how much usable energy is left in the battery at any given time. This is one of the most critical

6 FAQs about [How to calculate the battery degradation of new energy]

How is battery degradation calculated?

The battery degradation comes from cyclic and calendar aging. The cyclic aging normally accounts for the C-rate, temperature, DoD usage and No. of cycles. On the other hand, the calendar aging takes into account the SOC, temperature and time. There is no formula as such for the battery degradation calculation.

What is a linear model of battery degradation?

Linear-high: the battery degradation cost is proportional to the discharge power, which is a linear model. This is widely used because of its easy implementation and convexity. This model approximates the impact on the degradation for all ranges of SoC as linear, thus, it cannot reflect the further reduction of cycle life as the DoD increases.
