1. A control device that controls a battery mounted on a vehicle, the control device comprising one or more processors configured to:
receive, via a communication network, a physical quantity of the battery detected by one or more sensors that are mounted on the vehicle, the physical quantity including a voltage, a current, and a temperature of the battery;
disconnect a relay in response to the physical quantity exceeding a predetermined value, the relay being provided between the battery and a predetermined device to which power is supplied from the battery;
detect a signal indicating that communication has been established between the control device and a system involved in operation of the vehicle;
change, while the relay is in a disconnected state, a length of a first time period in response to detecting the signal, the first time period being a standby time before connecting the relay:
connect the relay when a voltage difference between one end and another end of the relay has been continuously less than a predetermined voltage value for the first time period without the signal being detected; and
connect the relay when the signal is detected and the voltage difference between the one end and the another end of the relay has been continuously less than the predetermined voltage value for the changed first time period.
