Problems solved by technology

[0006] However, in the above-mentioned conventional structure, there is a problem that, when the charging device is connected to the external power supply in advance, the charging cable part becomes a factor in the state where the vehicle side is not connected to the charging device later, and leakage occurs. In the case of the case, or in the case of leakage from the power supply to the case of the main body of the charging device, the leakage cannot be detected, and the user is also affected by the leakage when the user is in contact with the charging cable or the case.

Embodiment approach 1

[0027] figure 1 It is a figure schematically showing the charging device for automobiles in Embodiment 1 of the present invention.

[0028] exist figure 1 Among them, 1 is a charging device, one end of the charging device 1 has a plug 4 and the other end has a charging port 6, the plug 4 is connected to the socket 3 of the external power supply 2 through a power cable 1a, and the charging port 6 is connected through a charging cable 13 It is connected to an inlet 5 of an electric vehicle 22 or the like. In addition, the charging device 1 includes a control device 7 that manages the operation of the charging device 1 . A CCID (Charging Circuit Interrupt Device: Charging Circuit Interrupt Device) 9 composed of a relay 8 and the like is included. In addition, a switch 10 is provided in the charging port 6 of the charging device 1 , and the switch 10 is closed when the charging port 6 of the charging device 1 is correctly connected to the inlet port 5 provided on the electric...

Embodiment approach 2

[0047] exist Figure 5 Among them, 21 is a timer unit, which is used for measuring time, controlled by the control device 7, and sends the measured time to the control device 7. Other structures are the same as those in Embodiment 1.

[0048] The timer unit 21 is configured to receive an instruction from the control device 7 to work so as to measure the following time: the time since the plug 4 is connected to the socket 3; the time since the external power supply 2 starts to be supplied to the charging device 1; The time from when the pilot signal terminal 15 is connected to the specified terminal of the electric vehicle; or the time from when the voltage of the pilot circuit 16 changes due to the action of the oscillator 19, the resistance element 20 and the resistance circuit network on the side of the electric vehicle, etc. .

[0049] By adopting the above-mentioned structure, by the operation of the timer unit 21, even if the charging port 6 is not connected to the inle...

Abstract

There are provided a control device, a power-supply cord, and a charging cable to be connected to an automobile, wherein the control device includes an electric-leakage detection portion for detecting an electric leakage in the charging cable or the automobile, a connection detection portion for detecting the charging cable being connected to the automobile, and a power-supply interruption portion for controlling supply of electricity from the power-supply cord to the charging cable, and, further, the control device has a function of activating the electric-leakage detection portion in a predetermined case, in a state where the automobile charging apparatus is supplied with a commercial power supply.

Description

technical field [0001] The invention relates to a charging device, which is used for charging electric vehicles, hybrid vehicles and other vehicles that need to be charged from external commercial power sources or equipment power sources. Background technique [0002] Conventional charging devices for electric vehicles or hybrid vehicles have the following structure: when the charging device is connected to an external power source in advance, and then the charging device is also connected to the vehicle side, the leakage detection function is activated, Determine whether there is an abnormality in the charging device. [0003] Alternatively, it is possible to determine whether there is an abnormality in the charging system before the charging device is connected to the power source when the charging device is connected to the vehicle without the charging device being connected to the power source in advance (for example, refer to Patent Document 1). [0004] Patent Documen...
