Control device, power supply system, and control method

A control device provided in an electrical power supply system configured to be capable of supplying electrical power from a first electrical power generating device and a first electrical power storage device to a first winding of a double-winding motor, and to be capable of supplying electrical power from the first electrical power generating device to the first electrical power storage device, and further, to be capable of supplying electrical power from a second electrical power generating device and a second electrical power storage device to a second winding of the double-winding motor, and to be capable of supplying electrical power from the second electrical power generating device to the second electrical power storage device, the control device comprising:

• at least one processor configured to execute a computer executable instruction that is stored in a memory;
• wherein, by the computer executable instruction being executed by the at least one processor, the control device:
• determines whether or not an electrical current value acquired using an electrical current sensor configured to detect a charging or discharging electrical current of the first electrical power storage device is less than or equal to a determination threshold value used for determining whether or not charging or discharging is occurring;
• in a case that it is determined that the electrical current value acquired by the electrical current sensor is less than or equal to the determination threshold value, carries out a control in order to make the electrical current value greater than the determination threshold value;
• and
• in a case that, despite the control being carried out in order to make the electrical current value greater than the determination threshold value, the electrical current value acquired using the electrical current sensor is less than or equal to the determination threshold value, determines that a disconnection has occurred in a wiring connected to the first electrical power storage device.

A control method in which at least one processor executes a control of an electrical power supply system configured to be capable of supplying electrical power from an electrical power generating device and an electrical power storage device to a load device, and further, to be capable of supplying electrical power from the electrical power generating device to the electrical power storage device, the control method comprising:

• determining whether or not an electrical current value acquired using an electrical current sensor configured to detect a charging or discharging electrical current of the electrical power storage device is less than or equal to a determination threshold value used for determining whether or not charging or discharging is occurring;
• carrying out, in a case that it is determined that the electrical current value acquired by the electrical current sensor is less than or equal to the determination threshold value, a control in order to make the electrical current value greater than the determination threshold value;
