Nuclear Magnetic Resonance Measurements on Electrical Components Such as in Particular Batteries and Capacitors

Abstract

A method allows for nuclear magnetic resonance measurements to be carried out on electrical components such as batteries or capacitors. In the process, the component is directly integrated in a resonant circuit of a nuclear magnetic resonance probe head in that the poles are electrically connected to the other elements of the resonant circuit, and the probe head is then introduced in a temporally and spatially constant magnetic field. Pulsed nuclear magnetic resonance measurements are carried out, in which a spin resonance signal is generated by at least one high-frequency pule and is recorded. The spectrum formed from this spin resonance signal is dependent on the state of the component, in particular on the state of charge of a battery or on the general state of the battery or the capacitor.

Dependencies are inferred from the claim text.
