Abstract:
1. A device to control charging of a battery with power supplied from a power supply located outside a vehicle via a charge cable, the device comprising: a first microcomputer configured to receive a signal that is transmitted from a signal generating unit in the charge cable and that is corresponding to a state of power supply from the outside power supply, configured to turn on a charge mode signal when the signal changes from an unchanging state lasting for a predetermined period of time, configured to turn off the charge mode signal upon detecting that a charge completion signal output from a second microcomputer is turned off, and configured to turn on again the charge mode signal when the first microcomputer turns off the charge mode signal before detecting that the charge completion signal is turned off; and the second microcomputer configured to charge the battery based on power supplied from the outside power supply via the charge cable upon detecting the charge mode signal that is turned on by the first microcomputer, and configured to turn off the charge completion signal when the charging is complete.
