1. A charging device for charging a vehicle-side electric storage unit of a vehicle-side device having a first vehicle-side connection terminal, a second vehicle-side connection terminal and a vehicle-side controller electrically connected between the first vehicle-side connection terminal and the second vehicle-side connection terminal, the charging device comprising:
a first power source;
a first device-side connection terminal being connectable to the first vehicle-side connection terminal;
a second device-side connection terminal being connectable to the second vehicle-side connection terminal;
a first resistance electrically connected between the first power source and the first device-side connection terminal;
a detection unit configured to detect an inter-terminal voltage between the first device-side connection terminal and the second device-side connection terminal, the detection unit including a comparator that compares the inter-terminal voltage to a predetermined voltage; and
a device-side controller configured to determine a change from a connected state to a non-connected state has occurred upon determining the inter-terminal voltage detected by the detection unit is greater than the predetermined voltage,
the connected state being a state where the first device-side connection terminal and the first vehicle-side connection terminal are connected to each other and the second device-side connection terminal and the second vehicle-side connection terminal are connected to each other, and the non-connected state being a state where the first device-side connection terminal and the first vehicle-side connection terminal are not connected to each other and the second device-side connection terminal and the second vehicle-side connection terminal are not connected to each other.
