Abstract: A photovoltaic energy storage system includes an energy storage device, an inverter, a photovoltaic array device, a DC/DC conversion device and a controller. When an output voltage of the photovoltaic array device is greater than or equal to a predetermined threshold value, the photovoltaic energy storage system is operated in a first working mode. When the output voltage of the photovoltaic array device is lower than the predetermined threshold value, the photovoltaic energy storage system is operated in a second working mode. The DC/DC conversion device includes a bypass switch and a DC/DC converter. When the photovoltaic energy storage system is operated in the second working mode, the bypass switch is turned on and the DC/DC converter is disabled. Consequently, the electric power of the energy storage device is transmitted to the inverter through the bypass switch.

Abstract: A motor demagnetization detection method includes the following steps. The speed of a motor is calculated according to the rotation angle of the motor. When determining that the motor respectively maintains a first and second steady state according to the speed, the three-phase current values of the motor are received to obtain first and second steady-state data. An equivalent magnetic flux is calculated according to the first and second steady-state data. The motor is repeatedly driven to maintain the first and second steady states, the first and second steady-state data are updated according to the three-phase current values, and the equivalent magnetic flux is again calculated to generate equivalent magnetic fluxes. A magnetic flux change is calculated according to equivalent magnetic fluxes. A demagnetization warning is issued according to a comparison of the magnetic flux change and a demagnetization warning value.
