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.
It also has been used for energy storage in hybrid electric vehicle fields. As lithium-ion batteries discharge during use, it’s important for users to understand the battery SOE (state of energy) – or how much charge is remaining. Knowing the state of energy can help you better manage the runtime of your devices before the next recharge is needed.
An accurate estimation of the residual energy, i. e., State of Energy (SoE), for lithium-ion batteries is crucial for battery diagnostics since it relates to the remaining driving range of battery electric vehicles. Unlike the State of Charge, which solely reflects the charge, the SoE can feasibly estimate residual energy.
Equation (1.5) defines the SoE for the battery pack as the ratio of the remaining energy to the maximum available en- ergy. Both remaining energy and maximum available energy are a function of the OCV of the battery pack.
There are various methods for estimating battery State of Energy (SOE), including the direct calculation method, power integration method, OCV method, model-based filtering algorithm, machine learning method, and joint estimation method.
An accurate battery SOE estimation is vital for proper LIB and BMS operation. Factors that affect the battery State of Energy readings can be attributed to a multifaceted interplay of four crucial elements, each exerting its influence on the accuracy and reliability of energy measurements. These factors include:
