Powerful, safe batteries are a key component in the success of electric mobility. This makes measuring a battery’s capacity and state a crucial factor. The most informative method of doing this is impedance spectroscopy. Impedance itself cannot be measured directly; instead, it is calculated from the relationship between current and voltage. Impedance provides information on the battery’s state of charge (SoC) and permits conclusions regarding its state of health (SoH, i.e., the condition inside the battery, where the cathode, anode and electrolyte are located) or its safety status.
