To this end, the remote management server 29 stores and maintains a correspondence relation between vehicle identification information and second meter identification information for each of the electric vehicles in a matching table 29-1.
That is, the matching table 29-1 is used to determine which home each of the electric vehicles belongs to.
The method for managing the matching table may be variously configured. For example, if an electric vehicle owner, a management staff of an apartment building, etc. informs a manager of the remote management server of vehicle identification information (e.g., vehicle number) and an address of the electric vehicle owner, the manager of the remote management server may renew the matching table 29-1.
Generally, the remote management server 29 maintains the correspondence relation between the address of each home and the second meter installed in the corresponding home so as to remotely inspect the amount of energy used in each home. Thus, the second meter can be specified using the address of the electric vehicle owner, and accordingly, the matching table can be maintained.
FIG. 7 shows an example of the operating process of the remote management server 29. If the remote management server 29 receives electric vehicle information (S211), the remote management server 29 identifies which second meter corresponds to electric vehicle information of the received electric vehicle information by inquiring the matching table (S212). That is, the remote management server 29 identifies to whom the electric vehicle information received at the step S212 will be transmitted.
Then, the remote management server 29 transmits the electric vehicle information to the second meter identified at the step S212 (S213).
If the remote management server 29 transmits the electric vehicle information, the second meter in the corresponding home receives the electric vehicle information, and transfers the received electric vehicle information to the IHD device 24 using various wired/wireless near-field communication schemes.
The IHD device 24 stores the electric vehicle information received from the second meter 23, and displays the stored electric vehicle information in various forms as occasion demands.
FIG. 8 shows an example of a screen provided by the IHD device 24. FIG. 8A is an example of a screen 311 on which energy related information including information on an energy consumption amount, information on an energy consumption rate, etc. is displayed.
