PROBLEM TO BE SOLVED: To enhance the surplus regenerative electric power absorbing capacity of a gas turbine without deteriorating the thermal efficiency of the gas turbine in operation of a range extender.SOLUTION: A range extender for an electric motor car drives a power generator 28 by a gas turbine 10 which is equipped with a heat exchanger 18 for preheating supply air compressed in a compressor 12 with exhaust gas from the turbine. A surplus regenerative electric power absorbing device uses the range extender, as a means for absorbing surplus regenerative electric power which is generated exceeding an electric power amount to be charged in a battery during regenerative braking, and is provided with a supply air discharge valve 20 for properly discharging supply air, which is compressed in the compressor, before the heat exchanger.SELECTED DRAWING: Figure 1 |
