Document Type and Number:
Japanese Patent JP2023054718
Kind Code:
A
Abstract:
To suppress drop of voltage of a main machine when a traveling motor shifts from regeneration operation to power running operation without increasing a capacity of a smooth capacitor.SOLUTION: An electric vehicle for driving a power generator (12) by an engine (11) and driving a traveling motor (10) by using generated power includes: a first DC/DC converter (20) for inputting regenerative power output from the traveling motor and outputting the power to vehicle load devices (22, 31) by regeneration operation of the traveling motor; and a control device (40) for controlling the power generator and the first DC/DC converter. The control device controls reduction of output power of the first DC/DC converter in accordance with reduction of the regenerative power.SELECTED DRAWING: Figure 11
