PROBLEM TO BE SOLVED: To prevent noise while driving a generator from giving a sense of discomfort to the people in the neighborhood when an electric vehicle supplies and charges a battery on the electric vehicle with electricity. SOLUTION: Running conditions of the vehicle 1 are classified into a first range running condition which the vehicle 1 is running in a first range and a second range running condition which the vehicle 1 is running in the other second range, and the data is stored in a control device 16. When the vehicle 1 is running in the first range running condition and the control device 16 determines that an amount of charged electricity A on a battery 14 excesses a certain value A2, the generator 15 is stopped by control of the control device 16. When the control device 16 determines that the vehicle 1 is in the second range running condition, the generator 15 is driven by the control device 16 in that the less the battery 14 has the charged electricity A, the more the generator 15 supplies electricity to the battery 14. |
