PURPOSE:To provide a communication control system for electric automobile utilizing the charging path of battery in which charging operation of battery is simplified. CONSTITUTION:An electric automobile 1 comprises a local area network and a communication unit 5 high frequency coupled through capacitors 15, 16 with the charging wiring 4 for a battery 3, whereas a charging power supply section 2 comprises a communication unit 7 high frequency coupled through capacitors 12, 13 with a charging wiring 6. The battery 3 in the electric automobile 1 is charged by the charging section 10 in the charging power supply section 2 when connectors 8, 9 are connected. On the other hand, high frequency signals are communicated between the communication units 5 and 7 through the charging wires 4, 6 and the connectors 8, 9. Charging information, e.g. type, voltage, etc., of the battery 3, is transmitted from the communication unit 5 to the communication unit 7 which controls the charging section 10 based on the charging information thus charging the battery 3 automatically under optimal conditions. |
