## Abstract

In a first state, a control device executes processes including a step of determining whether a predetermined time has elapsed from a previous cleaning time, a step of determining whether a movable portion has been elevated a predetermined number of times from the previous cleaning time, a step of determining whether there is precipitation from the previous cleaning time, a step of executing injection control, and a step of resetting an elapsed time, the number of elevations, and a precipitation flag.

## Claims

### Claim 1

A movable charging facility that is installed in a recess provided on a ground and that is able to charge a power storage device mounted on a vehicle, the charging facility comprising:
a movable portion including a connecting device that is connectable to the power storage device;
an elevating device that elevates and lowers the movable portion such that any of a plurality of states is established, the states including a first state in which the movable portion is stored underground and a second state in which the movable portion is exposed on the ground;
an injection device that injects cleaning liquid toward a side surface of the charging facility; and
a control device that controls operation of the elevating device and operation of the injection device, wherein the control device controls the injection device such that the injection device injects the liquid toward the side surface of the charging facility when at least either one of predetermined execution conditions is satisfied, the execution conditions being a condition on an elapsed time from a previous injection time of the liquid, a condition on the number of times the movable portion is elevated, and a condition on presence or absence of precipitation.

### Claim 2 (depends on 1)

The charging facility according to claim 1, wherein the execution conditions include at least one of a condition that a predetermined time has elapsed from the previous injection time, a condition that the number of times the movable portion has been elevated at and after the previous injection time exceeds a threshold value, and a condition that precipitation has been observed at an installation point of the charging facility at and after the previous injection time.

### Claim 3 (depends on 1)

The charging facility according to claim 1, further comprising a storage unit that stores precipitation in a predetermined area including the installation point of the charging facility as a part of the cleaning liquid, wherein the control device predicts an amount of precipitation stored in the storage unit, and uses a prediction result to set an amount of the liquid to be injected to the charging facility at a time of injection of the liquid.

### Claim 4 (depends on 1)

The charging facility according to claim 1, wherein the injection device includes
a supply passage connected to an injection port provided at a position on an inner wall of the recess facing the side surface of the charging facility in the first state, and
a pump that pumps the liquid into the supply passage.

### Claim 5

A control method of a charging facility, the control method being a control method of a movable charging facility that is installed in a recess provided on a ground and that is able to charge a power storage device mounted on a vehicle, the charging facility including a movable portion including a connecting device that is connectable to the power storage device, an elevating device that elevates and lowers the movable portion such that any of a plurality of states is established, the states including a first state in which the movable portion is stored underground and a second state in which the movable portion is exposed on the ground, and an injection device that injects a cleaning liquid toward a side surface of the charging facility, the control method comprising:
a step of determining whether at least either one of predetermined execution conditions is satisfied, the execution conditions being a condition on an elapsed time from a previous injection time of the liquid, a condition on the number of times the movable portion is elevated, and a condition on presence or absence of precipitation; and
a step of controlling the injection device such that the injection device injects the liquid toward the side surface of the charging facility when the at least either one of the execution conditions is satisfied.
