## Abstract

An operation management system includes: a server; a first obtainer that obtains charge amount information on a charge amount of an electric vehicle; a first transmitter that transmits the charge amount information obtained by the first obtainer to the server; a second obtainer that obtains driving history information on a driving history of the electric vehicle; and a second transmitter that transmits the driving history information obtained by the second obtainer. The server includes: an estimator that obtains the charge amount information and the driving history information, and estimates a potential range of travel of the electric vehicle based on the charge amount information and the driving history information obtained; and a display controller that causes a display to display an estimation result of the estimator.

## Claims

### Claim 1

An operation management system for managing operation of an electric vehicle, the operation management system comprising:
a server;
a first obtainer that obtains charge amount information on a charge amount of the electric vehicle;
a first transmitter that transmits the charge amount information obtained by the first obtainer to the server;
a second obtainer that obtains driving history information on a driving history of the electric vehicle; and
a second transmitter that transmits the driving history information obtained by the second obtainer, wherein
the server includes:
an estimator that obtains the charge amount information and the driving history information, and estimates a potential range of travel of the electric vehicle based on the charge amount information and the driving history information obtained; and
a display controller that causes a display to display an estimation result of the estimator.

### Claim 2 (depends on 1)

The operation management system according to claim 1, wherein
the electric vehicle or charging equipment for charging the electric vehicle includes a charging cable for electrically connecting the electric vehicle and the charging equipment, and
the first obtainer and the first transmitter are disposed in an adapter that is to be electrically connected to one end of the charging cable.

### Claim 3 (depends on 2)

The operation management system according to claim 2, further comprising:
a mobile terminal, wherein
the first transmitter transmits the charge amount information to the server via the mobile terminal.

### Claim 4 (depends on 3)

The operation management system according to claim 3, wherein
the first transmitter transmits the charge amount information to the mobile terminal by close-range wireless communication, and
the mobile terminal transfers the charge amount information transmitted by the first transmitter to the server via a network.

### Claim 5 (depends on 4)

The operation management system according to claim 4, wherein
the close-range wireless communication is established by Bluetooth (registered trademark).

### Claim 6 (depends on 1)

The operation management system according to claim 1, wherein
the second obtainer and the second transmitter are disposed in an in-vehicle device that is provided in the electric vehicle and is compliant with electronic toll collection (ETC) 2.0,
the second transmitter transmits the driving history information to an intelligent transport systems (ITS) spot, and
the estimator of the server obtains the driving history information via the ITS spot.

### Claim 7

An operation management method for managing operation of an electric vehicle, the operation management method comprising:
(a) obtaining charge amount information on a charge amount of the electric vehicle;
(b) transmitting the charge amount information obtained in (a) to a server;
(c) obtaining driving history information on a driving history of the electric vehicle;
(d) transmitting the driving history information obtained in (c);
(e) obtaining, by the server, the charge amount information and the driving history information, and estimating a potential range of travel of the electric vehicle based on the charge amount information and the driving history information obtained; and
(f) causing, by the server, a display to display an estimation result of (e).
