In-vehicle charging apparatus
First Claim
1. An in-vehicle charging apparatus that charges a high voltage battery and a low voltage battery with use of a charging cable configured to start supply of power to the in-vehicle charging apparatus based on a state of a voltage of a pulse signal preliminarily sent to the in-vehicle charging apparatus, the in-vehicle charging apparatus comprising:
- a charging control section that operates with power supplied from the low voltage battery, and controls the charging;
a voltage drop switch whose on/off is controlled by the charging control section, the voltage drop switch being configured to reduce the voltage of the pulse signal sent by the charging cable when the voltage drop switch is in an on state; and
a first switch that is turned on by a physical auxiliary charging switch and reduces the voltage of the pulse signal sent by the charging cable when the first switch is in an on state, whereinthe power from the charging cable is supplied to the low voltage battery or the charging control section when the first switch is turned on.

Abstract
An in-vehicle charging apparatus (100) has: a charge control ECU (10), which operates with power supplied from a low-voltage battery (16), and which controls charging; an S2 switch, which is on/off controlled by means of the charge control ECU (10), and which reduces a voltage of the pulse signals when the switch is in the on-state; and a switch (SW1), which is controlled to be in an on-state by means of units other than the charge control ECU (10), and which reduces the voltage of the pulse signals when the switch is in the on-state. In the cases where the switch (SW1) is turned on, power from a charging cable (200) is supplied to the low-voltage battery (16) or the charge control ECU (10).
