When we talk about SOE, it is reflected as residual energy of the battery which is related to the amount of charge that the battery can discharge and the voltage during the battery discharge. Compared with SOC, SOE is more suitable for estimating the driving range of EVs
It is divided into two types
1- Theoretical residual energy (TRE)
TRE is the energy that can be released when the battery is discharged to SOC=0 with a very small discharge?
2- Residual discharge energy (RDE)
RDE is the energy that can be released by the battery when it is discharged to the cutoff voltage under a certain load condition and at a certain ambient temperature
