Abstract
A device for recovering electric energy in a DC motor-driven electric vehicle. The device includes a battery; a first inverter; an inductor; a first rectifier bridge or a second inverter; a DC motor; a second rectifier bridge or a third inverter; and a charger. The anode and the cathode of the battery are connected to input ends of the first inverter, respectively. One output end of the first inverter is connected to one end of a primary coil of the inductor. Another output end of the first inverter is connected to one input end of the first rectifier bridge or the second inverter. Another end of the primary coil of the inductor is connected to another input end of the first rectifier bridge. The charger is connected to the anode and the cathode of the battery for supplying power from an external power supply.
