<p>A sensor-based electrical energy recovery device for use in an alternating current motor electric car, comprising a battery (E), a first single-phase or three-phase inverter (INV), a sensor (T1), an alternating current motor (M1), a bridge rectifier or second inverter, and an external power charger (QL). The positive and negative electrodes of the battery respectively are connected to an input end of the first single-phase or three-phase inverter (INV). An output end of the first single-phase or three-phase inverter (INV) is connected to the alternating current motor (M1) via a primary coil of the sensor (T1). A secondary output end of the sensor (T1) is connected to an input end of the bridge rectifier or second inverter. The output end of the bridge rectifier or second inverter is connected respectively to the positive and negative electrodes of the battery (E). The external power charger (QL) is connected to the positive and negative electrodes of the battery (E) to recharge the battery.</p> |
