Abstract
A power detecting device includes a vehicle driving system, a battery detecting module and a controlling module. A first stator winding and a second stator winding are synchronized and connected in parallel with each other. A first end of a first current sensor is coupled to a first-phase winding end of the first stator winding for measuring a first-phase current. A first end of a second current sensor is coupled to a second-phase winding end of the first stator winding for measuring a second-phase current. The battery detecting module is coupled to a first power supply for measuring a current signal and a voltage signal. A controller generates a first power according to the current signal and the voltage signal and generates a second power according to a plurality of data from a database. The controller compares the first power with the second power to generate a detecting result.
