PROBLEM TO BE SOLVED: To reduce energy loss by controlling the input and output of energy to a battery 3. SOLUTION: An engine 1 is started and stopped, according to motor output. A control means is provided that controls the engine 1, in such a way that the generated output of a generator 9 will not exceed the motor output. Because the generated output of the generator 9 is supplied directly to the motor 5, energy loss can be reduced. |
