Wire housing device, vehicle equipped with the same, and power feeding device
In a cord reel capable of housing a power cord for transmitting electric power from an external power source to a vehicle that can be externally charged, pulling-out of the power cord wound around the cord reel from the cord reel is suppressed based on a temperature of the power cord. This can prevent a hot charging cord from exerting influence on the surroundings, such as breakage of equipment or the like which touches the hot charging cord.
1. A wire housing device configured to be capable of housing a wire for transmitting electric power from a power source, the wire housing device comprising:
an inhibition unit configured to suppress pulling-out of the wire from the wire housing device in accordance with a temperature of the wire.
2. The wire housing device according to claim 1 , further comprising:
a temperature detection unit configured to detect the temperature; and
a control unit configured to control the inhibition unit to suppress pulling-out of the wire from the wire housing device based on the temperature.
3. The wire housing device according to claim 2 , wherein the control unit controls the inhibition unit to suppress pulling-out of the wire if the temperature is higher than a first threshold value.
4. The wire housing device according to claim 3 , wherein the control unit releases suppression of pulling-out of the wire if the temperature becomes higher than the first threshold value and thereafter becomes lower than a second threshold value which is lower than the first threshold value.
5. The wire housing device according to claim 2 , further comprising:
a drum configured wind and house the wire; and
a ratchet mechanism provided to a rotation shaft of the drum,
wherein the inhibition unit includes a rotation suppression device configured to suppress rotation of the drum by operating under control of the control unit and engaging the ratchet mechanism.
6. A vehicle capable of being charged using electric power from an external power source, comprising:
a power receiving wire configured to transmit the electric power from the external power source to the vehicle;
a wire housing device configured to house the power receiving wire; and
an inhibition unit configured to suppress pulling-out of the power receiving wire from the wire housing device based on a temperature of the power receiving wire.
7. The vehicle according to claim 6 , further comprising:
a temperature detection unit configured to detect the temperature; and
a control unit configured to control the inhibition unit to suppress pulling-out of the power receiving wire from the wire housing device based on the temperature.
8. The vehicle according to claim 7 , wherein the control unit controls the inhibition unit to suppress pulling-out of the power receiving wire if the temperature is higher than a first threshold value.
9. The vehicle according to claim 8 , wherein the control unit releases suppression of pulling-out of the power receiving wire if the temperature becomes higher than the first threshold value and thereafter becomes lower than a second threshold value which is lower than the first threshold value.
10. A power feeding device for transmitting electric power from an external power source, comprising:
a power feeding wire configured to transmit the electric power from the external power source;
a wire housing device configured to house the power feeding wire; and
an inhibition unit configured to suppress pulling-out of the power feeding wire from the wire housing device based on a temperature of the power feeding wire.
11. The power feeding device according to claim 10 , further comprising:
a temperature detection unit configured to detect the temperature; and
a control unit configured to control the inhibition unit to suppress pulling-out of the power feeding wire from the wire housing device based on the temperature.
