Claim 10:
11. A control device mountable on a vehicle, the vehicle being 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 power supply cord connected to a positive electrode and a negative electrode of the battery, and a second power supply cord connected to the positive electrode and the negative electrode of the battery, the control device comprising:
a first circuit;
a second circuit; and
a housing in which the first circuit and the second circuit are stored,
wherein the first power supply cord is set to connect at least the positive electrode and the negative electrode of the battery to a first power supply portion and a first ground portion of the first circuit, respectively,
wherein the second power supply cord is set to connect 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.
