Abstract

A power cable is connected from an external commercial power supply, and an in-vehicle battery is charged. Using the power cable as a communication conduit, communication is conducted with the outside world. In particular, by communication during charging, regional information regarding the current location, where the charging is being performed, or regional control parameter information is obtained. A control parameter of a vehicle is then set in accordance with the obtained information.

Claims

1. A vehicle communication system in which an in-vehicle battery is charged from an external power supply connected thereto via an electric power line and external communication using the electric power line as a communication conduit is enabled, the vehicle communication system characterized in that:

through communication performed during charging, information regarding either the geographical area where the charging is being performed or control parameter information set in accordance with the geographical area where the charging is performed is obtained, and a control parameter of the vehicle is set in accordance with the obtained information.

2. The vehicle communication system according to claim 1,

wherein the control parameter relates to charging and discharging control of the battery.

3. The vehicle communication system according to claim 1,

wherein the control parameter is an upper or lower limit setting value in charging and discharging control of the battery.

4. The vehicle communication system according to claim 1,

wherein the control parameter relates to a battery temperature control.
