OG exemplary drawing
 
1. A vehicle provided with at least a first wheel and a second wheel so as to be movable by rotating the first wheel and the second wheel, the vehicle comprising:
a battery;
a first circuit;
a second circuit;
a housing in which the first circuit and the second circuit are stored;
a first power supply cord connecting at least a positive electrode and a negative electrode of the battery to a first power supply portion and a first ground portion of the first circuit, respectively; and
a second power supply cord connecting at least the positive electrode and the negative electrode of the battery to a second power supply portion and a second ground portion of the second circuit, respectively,
wherein a second consumption current of the second circuit is possible to be larger than a first consumption current of the first circuit,
wherein the first circuit comprises a control circuit,
wherein the control circuit is configured to measure a voltage of the second power supply portion of the second circuit as a first voltage with reference to a potential of the first ground portion,
wherein the control circuit is configured to measure a voltage of the second power supply portion of the second circuit as a second voltage with reference to a potential of the second ground portion, and
wherein in a case in which the first voltage and the second voltage have a predetermined relationship, power supplied from the second power supply cord to the second circuit is set to be a predetermined value or less.
