Claims (4)

[Claims] 1. An electric motor connected to a power generation means, a propulsion means, a battery, a first power supply path for supplying an output current of the power generation means to the battery, and an output current from the battery. A second power supply path capable of supplying the electric motor to the electric motor, control means for controlling the output of the electric motor based on an output set value of output setting means, and detection means for detecting a state of charge of the battery. A first allowable charging area of the battery, and a second allowable charging area is set near an upper limit of the first allowable charging area in the first allowable charging area, and an increase rate of the output set value is less than a predetermined value. At this time, the battery output is controlled so as to satisfy the output value of the electric motor based on the output set value, and when the detected value is lower than the lower limit of the second allowable charging region based on the detected state of charge, the power generation output is reduced. Within a predetermined output range, the power generation output is increased, and when the detected value exceeds the upper limit value of the second allowable charging region, the power generation output is controlled so as to decrease and maintain the power generation output within the output range, When the rate of increase of the output set value is equal to or greater than a predetermined value, the battery is charged so as to satisfy the output equal to or greater than the output value of the electric motor based on the output set value within a range in which the detected value does not fall below the lower limit of the first allowable charging area. A hybrid drive type mobile device, wherein the output is controlled and the power generation output is controlled so as to increase the power generation output within a predetermined output range of the power generation output. 2. An electric motor connected to a power generation means, a propulsion means, a battery, a first power supply path for supplying an output current of the power generation means to the battery, and an output current from the battery. A second power supply path capable of supplying the electric motor to the electric motor, control means for controlling the output of the electric motor based on an output set value of output setting means, and detection means for detecting a state of charge of the battery. A first allowable charging area of the battery, and a second allowable charging area is set near an upper limit of the first allowable charging area in the first allowable charging area, and an increase rate of the output set value is less than a predetermined value.
