Abstract: This disclosure provides an estimation method applied to a state of health of a battery, which executes a recharging to a battery when a battery voltage is lower than a threshold voltage. During the recharging, a battery state of health estimation procedure is performed from a first depth of discharge detection point to a second depth of discharge detection point. During the battery state of health estimation procedure, a voltage difference between a current battery voltage and an initial open-circuit voltage is accumulated over time from the first depth of discharge detection point to the second depth of discharge detection point to obtain an accumulation of current sampled voltage difference. An accumulation of estimated DC internal resistances can be equivalently obtained by the accumulation of current sampled voltage difference. Afterwards, the state of health of the battery can be determined based on the accumulation of estimated DC internal resistance.

Abstract: A method for a direct current (DC) islanding detection based on positive feedback of a bus voltage at a specific frequency, essentially including three steps: extraction of a specific frequency component of the bus voltage, injection of a disturbance component of the specific frequency, and determination of DC islanding. The extraction of the specific frequency component of the bus voltage and the injection of the disturbance component of the specific frequency constitute a positive feedback mechanism in a power management unit control loop. In a grid-connected mode of a DC grid, the positive feedback mechanism fails due to a control action of a voltage management unit on a bus, and the bus voltage remains stable. In an islanding mode of the DC grid, under an action of the positive feedback mechanism, the power management unit allows the bus voltage to generate a self-excited oscillation at the specific frequency.
