Classification: CPC H | IPC H

Claim 6:
7. A method for measuring energy-charging rate of an energy harvester, comprising:
receiving an indication that an energy level at an energy storage is a reference level, wherein the energy storage is configured to store harvested energy, wherein the reference level is a predetermined voltage level and measured by a PMU;
receiving a discharge state signal after a predefined time interval elapsed from a discharge operation;
starting a time counter, upon receiving the discharge state signal, wherein the time counter is configured to measure a time elapse from a discharge level to the reference level;
measuring a charge time of the energy storage until the energy level at the energy storage reaches the reference level;
reading a time counter value as the charge time; and
determining the energy-charging rate between the discharge level and the reference level within the measured charge time.
