## Abstract

In a method, system and apparatus for managing vehicle energy, the amount of electric power needed for operating a vehicle is calculated, a surplus amount of electric power that is the current amount of battery power less the calculated amount of electric power is sold, or a number of received location information signals according to the current amount of battery power is adjusted.

## Claims

### Claim 1

a vehicle management apparatus configured to create current battery power information by checking current battery power, to check the number of times to receive location information signals, to transmit the current battery power information and the number of times to receive to a service apparatus, and if the adjusted number of times to receive location information signals is received from the service apparatus, to receive the location information signals according to the adjusted number of times; and
the service apparatus configured to compare the current battery power with a predetermined threshold when the current battery power information and the number of times are received from the vehicle management apparatus, to adjust the number of times depending on comparison results, and to transmit the adjusted number of times to the vehicle management apparatus.

### Claim 2

A vehicle energy management system comprising:
a vehicle management apparatus configured to monitor a state of a vehicle, to create current battery power information by checking current battery power, and to provide the current battery power information to a terminal;
a terminal configured to check the number of times to receive location information signals, to transmit to a service apparatus the current battery power information and the number of times to receive location information signals, and if the adjusted number of times to receive location information signals is received from the service apparatus, to receive the location information signals according to the adjusted number of times; and
the service apparatus configured to compare the current battery power with a predetermined threshold when the current battery power information and the number of times are received from the terminal, to adjust the number of times depending on comparison results, and to transmit the adjusted number of times to the terminal.

### Claim 3

A vehicle management apparatus comprising:

a control unit configured to create current battery power information by checking current battery power, to compare the current battery power with a predetermined threshold, to adjust the number of times depending on comparison results, and to control the GPS receiver to receive the location information signals according to the adjusted number of times.

### Claim 4 (depends on 3)

The vehicle management apparatus of claim 3, wherein the control unit is further configured to, if the current battery power is lower than the predetermined threshold, decrease the number of times to receive the location information signals.

### Claim 5 (depends on 3)

The vehicle management apparatus of claim 3, wherein the control unit is further configured to, if the current battery power is equal to or greater than the predetermined threshold, maintain or increase the number of times to receive the location information signals.

### Claim 6 (depends on 3)

The vehicle management apparatus of claim 3, wherein the control unit is further configured to, while the number of times to receive location information signals is adjusted, periodically check the current battery power, and to compare again the current battery power with the predetermined threshold.

### Claim 7

A vehicle energy management method comprising steps of:
at a vehicle management apparatus, checking current battery power;
at the vehicle management apparatus, comparing the current battery power with a predetermined threshold;
at the vehicle management apparatus, depending on comparison results, adjusting the number of times to receive location information signals; and
