Example: The Main Battery Storage Equation Rp R v i vocv + vp - + - Cp This main storage capacity is hidden inside the battery and cannot be directly measured. It is related to the Open-Circuit Voltage in a nonlinear relationship. ds = 1 i dt Q s = SOC (State of Charge) = the percentage of stored electricty Q = the maximumcapacity Compare it to a capacitor: dv = 1 i The main storage model dt C may be represented by a capacitor with C represented by Q
