Charging control device for electrically driven vehicle, and vehicle incorporating same

A charging control device for a motorcycle having a drive source;

• said charging control device comprising
• a power supply device arranged on said motorcycle, and being operable to perform drive control of said drive source;
• a charger arranged outside the motorcycle;
• a coupler for operatively connecting said power supply device and said charger with each other;
• said coupler being mounted on said motorcycle, and having a charging cable extending therefrom;
• wherein:
• said power supply device comprises
• a battery operatively connected with the drive source;
• a power drive unit connected with battery and said drive source;
• a first converter which sets a voltage inputted from the charger to a suitable voltage for charging the battery,
• a second converter which sets an output voltage of the first converter to a drive voltage for the power drive unit, and
• a contactor which connects an output of the first converter to the battery in response to a command from the power drive unit;
• said charger comprises a control unit including
• an identification voltage applying unit which applies an identification voltage on which a current limitation is imposed to the coupler;
• and
• a connection detection unit which starts outputting of a charge voltage in response to detection of dropping of the identification voltage to a predetermined voltage or below.

An electric vehicle comprising

• an electric motor;
• a coupler;
• and
• a power supply device for supplying power to said electric motor;
• said power supply device being operable to connect with a charger located outside the vehicle via said coupler;
• said power supply device comprising
• a battery including a battery management unit;
• a power drive unit connected with said battery management unit and said electric motor;
• a first converter which sets a voltage inputted from the charger to a suitable voltage for charging the battery;
• a second converter which sets an output voltage of the first converter to a drive voltage for the power drive unit;
• and
• a contactor which connects an output of the first converter to the battery management unit in response to a command from the power drive unit;
• wherein said charger is operable to apply an identification voltage on which a current limitation is imposed to the coupler;
• and to start outputting of a charge voltage in response to the detection of dropping of the identification voltage to a predetermined voltage or below.
