1. A charging controller that carries out charging control of a power storage mounted on a vehicle, wherein
the vehicle includes
a DC charging inlet,
a first ground fault detection circuit, and
a second ground fault detection circuit shorter in detection time period than the first ground fault detection circuit,
the charging controller is configured
to carry out first charging control when a charging cable which is not a prescribed charging cable is connected to the DC charging inlet, and
to carry out second charging control when the prescribed charging cable is connected to the DC charging inlet,
each of the first charging control and the second charging control is control for charging the power storage with DC power supplied from outside of the vehicle to the DC charging inlet,
in the first charging control, ground fault detection is carried out by using the first ground fault detection circuit during charging of the power storage, and
in the second charging control, ground fault detection is carried out by using the second ground fault detection circuit during charging of the power storage.
