## Abstract

Provided is a server including a communicator, and a controller electrically connected to the communicator. The controller is configured to receive, from a plurality of personal mobilities, first information related to a battery of each of the plurality of personal mobilities through the communicator, transmit, to a first personal mobility among the plurality of personal mobilities, a first control signal for causing a first conductive coil of the first personal mobility to be switched into a state for power transmission through the communicator, based on the first information, and transmit, to a second personal mobility among the plurality of personal mobilities, a second control signal for causing a second conductive coil of the second personal mobility to be switched into a state for power reception through the communicator.

## Claims

### Claim 1

A server comprising:
a communicator; and
a controller electrically connected to the communicator;
wherein the controller is configured to:
receive, from a plurality of personal mobilities, first information related to a battery of each of the plurality of personal mobilities through the communicator;
transmit, to a first personal mobility among the plurality of personal mobilities, a first control signal for causing a first conductive coil of the first personal mobility to be switched into a state for power transmission through the communicator, based on first information; and
transmit, to a second personal mobility among the plurality of personal mobilities, a second control signal for causing a second conductive coil of the second personal mobility to be switched into a state for power reception through the communicator;
wherein the first information includes a charge amount of the battery of each of the plurality of personal mobilities, and information indicating whether the battery of each of the plurality of personal mobilities is being charged; and
wherein the controller is further configured to identify the first personal mobility including a first battery, which is being charged, among the plurality of personal mobilities based on the information indicating whether the battery of each of the plurality of personal mobilities is being charged.

### Claim 2 (depends on 1)

The server of claim 1, wherein the first control signal includes a control signal for causing the first conductive coil of the first personal mobility to be switched into a state for power transmission, based on a first charge amount of the first battery of the first personal mobility being greater than or equal to a predetermined reference value.

### Claim 3 (depends on 1)

The server of claim 1, wherein the controller is further configured to transmit, to a third personal mobility among the plurality of personal mobilities, a third control signal for causing a third conductive coil of the third personal mobility to be switched into a state for power reception through the communicator.

### Claim 4 (depends on 3)

The server of claim 3, wherein the controller is further configured to determine an order in which the first personal mobility sequentially transmits power to the second personal mobility and then the third personal mobility, based on the charge amount of the battery of each of the plurality of personal mobilities, wherein the first control signal includes information related to the order.

### Claim 5 (depends on 1)

The server of claim 1, wherein the second control signal includes a control signal for causing the second conductive coil of the second personal mobility to be switched into a state for power transmission when the second battery of the second personal mobility is completely charged.

### Claim 6 (depends on 1)

The server of claim 1, wherein the controller is further configured to:
receive, from each of the plurality of personal mobilities, second information indicating an arrangement relationship of personal mobilities adjacent to each other through the communicator; and
identify the plurality of personal mobilities as being included in a personal mobility bundle based on the second information.

### Claim 7

A method of managing a personal mobility by a server, the method comprising:
receiving, from a plurality of personal mobilities, first information related to a battery of each of the plurality of personal mobilities through a communicator of a server;
transmitting, to a first personal mobility among the plurality of personal mobilities, a first control signal for causing a first conductive coil of the first personal mobility to be switched into a state for power transmission through the communicator, based on the first information; and
transmitting, to a second personal mobility among the plurality of personal mobilities, a second control signal for causing a second conductive coil of the second personal mobility to be switched into a state for power reception through the communicator;
wherein the first information includes a charge amount of the battery of each of the plurality of personal mobilities, and information indicating whether the battery of each of the plurality of personal mobility is being charged; and
wherein the method further comprises identifying the first personal mobility including a first battery, which is being charged, among the plurality of personal mobilities based on the information indicating whether the battery of each of the plurality of personal mobility is being charged.

### Claim 8 (depends on 7)

The method of claim 7, wherein the first control signal includes a control signal for causing the first conductive coil of the first personal mobility to be switched into a state for power transmission, based on a first charge amount of the first battery of the first personal mobility being greater than or equal to a predetermined reference value.

### Claim 9 (depends on 7)

The method of claim 7, further comprising transmitting, to a third personal mobility among the plurality of personal mobilities, a third control signal for causing a third conductive coil of the third personal mobility to be switched into a state for power reception through the communicator.
