Title:
A device and a method for precise energy device health condition (SoH) surveillance
Document Type and Number:
Japanese Patent JP6122432
Kind Code:
B2
Abstract:
A device and associated testing method for testing state of health of an energy device, comprising: applying electrical excitations to the energy device at a predetermined electrical excitation frequency ωe; applying mechanical excitations to the energy device at a predetermined mechanical excitation frequency ωm; measuring an electrically-induced phase difference Δθe (ωe) between voltage (V) and current (I) within the energy device from applying the electrical excitations; measuring a mechanically-induced phase difference Δθe (ωm) between voltage (V) and current (I) within the energy device from applying the mechanical excitations; and deducing the state-of-health of the energy device by comparing the electrically-induced phase difference Δθe (ωe) with the mechanically-induced phase difference Δθe (ωm).
