Charging system, vehicle, charging method, and control device
A charging system of an electrically powered vehicle includes a power storage device, a charging device that performs external charging for charging the power storage device with power received from an external power supply, a DCM that outputs information for informing a user of information about charging by the charging device, and an ECU that controls the charging device and the DCM. The ECU controls the charging device to perform the external charging, controls the charging device to limit charging power when a predetermined condition is satisfied during the charging, and controls the DCM to output information for informing the user of a remaining charging time calculated using charging power immediately before limitation while the charging power is limited. The user's feeling of strangeness can be reduced.
1. A charging system comprising:
a power storage device;
a charging device that performs external charging for charging the power storage device with power received from an external power supply;
an output device that outputs information for informing a user of information about charging by the charging device; and
a control device that controls the charging device and the output device,
the control device
controlling the charging device to perform the external charging,
controlling the charging device to limit charging power, when a predetermined condition is satisfied during the charging, and
controlling the output device to output information for informing the user of a remaining charging time calculated using charging power immediately before limitation, while the charging power is limited.
2. The charging system according to claim 1 , further comprising a connection unit to which a charging connector of a charging cable for externally supplying the power can be connected, and which can switch between a locking state where the connection unit mechanically locks the charging connector and an unlocking state where the connection unit does not mechanically lock the charging connector, wherein
the predetermined condition includes a condition that the connection unit switches to the unlocking state during the charging.
3. The charging system according to claim 1 , wherein, when the limitation of the charging power is canceled, the control device controls the output device to output information for informing the user of a remaining charging time calculated using charging power at a present time point.
4. The charging system according to claim 1 , wherein, while the charging power is limited, the control device controls the output device to output information for informing the user that the charging power is limited.
5. A vehicle comprising the charging system according to claim 1 .
6. A charging method performed by a charging system,
the charging system including
a power storage device,
a charging device that performs external charging for charging the power storage device with power received from an external power supply,
an output device that outputs information for informing a user of information about charging by the charging device, and
a control device that controls the charging device and the output device, the charging method comprising:
controlling, by the control device, the charging device to perform the external charging;
controlling, by the control device, the charging device to limit charging power, when a predetermined condition is satisfied during the charging; and
controlling, by the control device, the output device to output information for informing the user of a remaining charging time calculated using charging power immediately before limitation, while the charging power is limited.
7. A control device that performs control of external charging for charging a power storage device with power received from an external power supply, and control of output of information for informing a user of information about the external charging,
the control device
controlling charging power to be limited, when a predetermined condition is satisfied during charging while the control device performs the control of the external charging, and
performing the control of output of information for informing the user of a remaining charging time calculated using charging power immediately before limitation, while the charging power is limited.
8. The control device according to claim 7 , further comprising a connection unit to which a charging connector of a charging cable for externally supplying the power can be connected, and which can switch between a locking state where the connection unit mechanically locks the charging connector and an unlocking state where the connection unit does not mechanically lock the charging connector, wherein the predetermined condition includes a condition that the connection unit switches to the unlocking state during the charging.
9. The control device according to claim 7 , wherein, when the limitation of the charging power is canceled, the control device performs the control of output of information for informing the user of a remaining charging time calculated using charging power at a present time point.
10. The control device according to claim 7 , wherein, while the charging power is limited, the control device performs the control of output of information for informing the user that the charging power is limited.
