Charge device and in-vehicle apparatus
First Claim
1. A charge device that performs a communication with a vehicle via a communication line in a charge cable, the charge cable having (i) a built-in power line to provide an electric power to the vehicle for charging a secondary battery of the vehicle and (ii) the built-in communication line, the charge device comprising:
- a pilot communicator controlling and detecting a voltage level of the communication line to exchange charge progress notices with the vehicle to control a charge operation;
an in-band communicator sending and receiving charge information to and from the vehicle via the communication line, the charge information multiplexed with other signals on the communication line; and
a master controller controlling the in-band communicator, whereinthe master controller resets a slave controller included in the in-band communicator of a charge device based on a fulfillment of a preset condition regarding(i) detection contents of the pilot communicator,(ii) communication contents of the in-band communicator, or(iii) an operation state of the in-band communicator.

Abstract
A vehicle charge device performs a pilot communication and an in-band communication via communication lines that are integrated with electric power lines in a charge cable. The charge device includes a master controller that resets a slave controller of an in-band communicator if determined that the charge cable is pulled out from a connector of a vehicle. As a result, the system suffers less frequent in-band communication errors during which an in-band communication is disabled due to a malfunction of a computer for the in-band communication.

14. An in-vehicle apparatus communicating with a charge device on a vehicle having a secondary battery, the communication between the apparatus and the charge device performed via a communication line that is built in a charge cable together with a power line that is used for receiving an electric power for charging the secondary battery from the charge device, the in-vehicle apparatus comprising:
-
a pilot communicator controlling and detecting a voltage level of the communication line to exchange charge progress notices with the charge device to control a charge operation; an in-band communicator sending and receiving charge information to and from the charge device via the communication line, the charge information multiplexed with other signals on the communication line; and a master controller controlling the in-band communicator, wherein the master controller resets a slave controller included in the in-band communicator on the vehicle based on a fulfillment of a preset condition regarding (i) detection contents of the pilot communicator, (ii) communication contents of the in-band communicator, or (iii) an operation state of the in-band communicator.
