Status detection system and connection cable

1. A status detection system configured to detect a connection status among a power storage vehicle, an electrified vehicle, and a connection cable, the status detection system comprising:

the connection cable electrically connectable to the electrified vehicle or the power storage vehicle;

a first detection unit configured to detect an electrical connection status between the electrified vehicle and the connection cable;

a second detection unit configured to detect an electrical connection status between the power storage vehicle and the connection cable; and

a determination unit configured to make determination on an overall connection status among the power storage vehicle, the electrified vehicle, and the connection cable based on the electrical connection status between the electrified vehicle and the connection cable based on a detection result from the first detection unit and the electrical connection status between the power storage vehicle and the connection cable based on a detection result from the second detection unit(,)

wherein: the connection cable includes a cable portion, a first connector provided at a first end of the cable portion, and a second connector provided at a second end of the cable portion, each of the first connector and the second connector including a first terminal configured to be connected to an electrified vehicle-side identification terminal provided to the electrified vehicle and not to be connected to a power storage vehicle-side identification terminal provided to the power storage vehicle, and a second terminal configured to be connected to the power storage vehicle-side identification terminal and not to be connected to the electrified vehicle-side identification terminal;

the first detection unit is configured to detect the electrical connection status between the electrified vehicle and the connection cable based on an electrical status of the first terminal; and

the second detection unit is configured to detect the electrical connection status between the power storage vehicle and the connection cable based on an electrical status of the second terminal.

2. The status detection system according to claim 1 , wherein the first terminal and the second terminal are disposed in each of the first connector and the second connector so as not to overlap each other in a front view on a connection plane of each of the first connector and the second connector.

3. The status detection system according to claim 1 , further comprising a third detection unit configured to detect an electrical connection status between the connection cable and an external charger, wherein:

the connection cable is electrically connectable to the external charger; and

the determination unit is configured to make determination on an overall connection status between the external charger and the connection cable based on the electrical connection status between the external charger and the connection cable based on a detection result from the third detection unit.

4. The status detection system according to claim 3 , wherein:

the connection cable includes a cable portion, a first connector provided at a first end of the cable portion, and a second connector provided at a second end of the cable portion, each of the first connector and the second connector including a third terminal configured to be connected to a charger-side identification terminal provided to the external charger; and

the third detection unit is configured to detect the electrical connection status between the external charger and the connection cable based on an electrical status of the third terminal.

5. The status detection system according to claim 4 , wherein the third terminal is configured not to be connected to an electrified vehicle-side identification terminal and a power storage vehicle-side identification terminal.

6. A connection cable configured to electrically connect a power storage vehicle and an electrified vehicle and to electrically connect power storage vehicles, the connection cable comprising:

a first detection unit configured to detect an electrical connection status between the electrified vehicle and the connection cable; and

a second detection unit configured to detect an electrical connection status between the power storage vehicle and the connection cable (,)

further comprising: a first terminal configured to be connected to an electrified vehicle-side identification terminal provided to the electrified vehicle and not to be connected to a power storage vehicle-side identification terminal provided to the power storage vehicle; and

a second terminal configured to be connected to the power storage vehicle-side identification terminal and not to be connected to the electrified vehicle-side identification terminal, wherein:

the first detection unit includes a first sensor configured to detect an energization amount of the first terminal, and is configured to detect the electrical connection status between the electrified vehicle and the connection cable based on the energization amount detected by the first sensor; and the second detection unit includes a second sensor configured to detect an energization amount of the second terminal, and is configured to detect the electrical connection status between the power storage vehicle and the connection cable based on the energization amount detected by the second sensor.

7. The connection cable according to claim 6 , wherein:

the connection cable is configured to electrically connect the power storage vehicle and an external charger; and

the connection cable further includes a third detection unit configured to detect an electrical connection status between the external charger and the connection cable.
