Charge controller and charging system
First Claim
1. A charge controller configured to control a charging of a battery provided inside a vehicle using a control signal supplied from an external power source via a power cable,wherein the external power source apparatus switches the control signal from a non-oscillation state to an oscillation state when a preparation for power supply from the external power source apparatus is completed,wherein the charge controller includes, inside the vehicle,a control section which controls the charging of the battery andan activating section which activates the control section, wherein the control section changes a voltage of the control signal, andwherein the activating section includesan oscillation state judgment section which judges whether the control signal input from the external power source apparatus via the power cable is in the oscillation state or the non-oscillation state and outputs an oscillation state judgment signal andan activating signal generation section which generates an activating signal for activating the control section when the oscillation state judgment signal is switched from a state indicating non-oscillation to a state indicating oscillation.

Abstract
A charge controller for controlling the charging of a battery provided inside a vehicle using a control signal supplied from an external power source apparatus via a power cable includes a control section for controlling the charging of the battery and an activating section for activating the control section inside the vehicle. The external power source apparatus switches the control signal from a non-oscillation state to an oscillation state when the preparation for power supply is completed. The activating section has an oscillation state judgment section for judging whether the input control signal is in the oscillation state or the non-oscillation state and for outputting an oscillation state judgment signal and an activating signal generation section for generating an activating signal for activating the control section when the oscillation state judgment signal is switched from a state indicating non-oscillation to a state indicating oscillation.

10. A charging system configured to charge a battery provided inside a vehicle with power supplied from an external power source apparatus via a power cable,
wherein the external power source apparatus includes a signal output section which outputs an oscillation signal or a non-oscillation signal serving as a control signal for activating a charge controller provided inside the vehicle and a switching control section which switches the control signal from the non-oscillation signal to the oscillation signal when a preparation for power supply is completed, wherein the charge controller includes a control section which controls a charging of the battery and an activating section which activates the control section, wherein the control section changes a voltage of the control signal, and wherein the activating section includes: -
an oscillation state judgment section which judges whether the control signal input from the external power source apparatus via the power cable is in an oscillation state or a non-oscillation state and outputs an oscillation state judgment signal and an activating signal generation section which generates an activating signal for activating the control section when the oscillation state judgment signal is switched from a state indicating non-oscillation to a state indicating oscillation.
