Battery Thevenin (SOC)
This interactive simulator explores Battery Thevenin (SOC) in Electricity & Magnetism. V_oc(SOC), R_int(SOC), Coulomb-counted SOC vs charge/discharge current; terminal voltage trace. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Electricity & Magnetism.

How it works
First-order Thevenin equivalent with open-circuit voltage and internal resistance both depending on state-of-charge. Coulomb counting updates SOC from the applied current.
Key equations
V = Vₒ꜀(SOC) − I·R(SOC)
dSOC/dt = −I / (Ah·3600 s)
