Abstract
A charging controller carries out charging control of a power storage mounted on a vehicle. The vehicle includes a DC charging inlet. The charging controller carries out first charging control when a charging cable which is not a prescribed charging cable is connected to the DC charging inlet and carries out second charging control when the prescribed charging cable is connected to the DC charging inlet. For example, a time period for ground fault detection carried out during charging of the power storage is set differently between first charging control and second charging control. Alternatively, a response delay margin of a charging command is set differently between first charging control and second charging control.
Claims9
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.
A vehicle comprising:
- a DC charging inlet;
- a power storage;
- and
- a charging controller that carries out charging control of the power storage, wherein
- 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,
- in each of the first charging control and the second charging control, while the vehicle is connected to a power feed facility outside the vehicle through a charging cable connected to the DC charging inlet, the charging controller transmits a charging command for controlling charging power to the power feed facility,
- in the first charging control, the charging controller transmits the charging command with a first response delay margin to the power feed facility, and
- in the second charging control, the charging controller transmits the charging command with a second response delay margin smaller than the first response delay margin to the power feed facility.
