Charger/discharger
An EV-PCS, which is a charger/discharger, includes: a power converter, which is a charging/discharging unit that controls at least one of charging a storage battery mounted on an EV and discharging the storage battery; a charging/discharging cable extending from the power converter; and a charging/discharging connector for connecting the charging/discharging cable to the EV. The charging/discharging connector includes a temperature detection element having a surface covered with resin, the temperature detection element detecting the internal temperature of the charging/discharging connector. The power converter reduces a value of current flowing to the charging/discharging cable during the charge or discharge of the storage battery as the temperature detected by the temperature detection element rises.
1. A charger/discharger including a charging/discharging unit to control at least one of charging a storage battery mounted on a vehicle and discharging the storage battery, the charger/discharger comprising:
a cable extending from the charging/discharging unit; and
a connector to connect the cable to the vehicle, wherein
the connector includes a solenoid having a surface covered with resin, the solenoid being configured as a temperature detection element detecting an internal temperature of the connector, the solenoid having a coil to lock the connector connected to the vehicle to prevent removal of the connector from the vehicle during the charge or discharge of the storage battery, the solenoid keeping the connector locked after a power supply of the coil is lost after the connector is locked, and
the charging/discharging unit reduces a value of current flowing to the cable during the charge or discharge of the storage battery as the temperature detected by the solenoid rises.
2. The charger/discharger according to claim 1 , wherein
the solenoid detects the internal temperature of the connector from a change in a resistance value of the coil.
3. The charger/discharger according to claim 1 , wherein
a fuse is provided inside the connector, and
the fuse is covered with a heat radiation member.
4. The charger/discharger according to claim 1 , wherein a connector case of the connector is made of metal.
5. The charger/discharger according to claim 2 , wherein
a fuse is provided inside the connector, and
the fuse is covered with a heat radiation member.
6. The charger/discharger according to claim 2 , wherein a connector case of the connector is made of metal.
7. The charger/discharger according to claim 3 , wherein a connector case of the connector is made of metal.
8. The charger/discharger according to claim 5 , wherein a connector case of the connector is made of metal.
9. The charger/discharger according to claim 1 , wherein a connector case of the connector is made of resin.
