Description

  The present invention relates to a charging stand that supplies electric power for charging a battery mounted on an electric vehicle.

As a charging device for supplying electric power for charging a battery mounted on an electric vehicle, a charging stand for charging an unspecified number of electric vehicles has been installed. The conventional charging device is simply connected to a commercial power source via a breaker, and is charged by inserting a plug on the electric vehicle side into the outlet (see, for example, Patent Document 1).
JP 11-299008 A

  However, when charging the battery of an unspecified large number of electric vehicles, such as a general gas station, there is a risk that the driver or passenger will touch the charging device and cause malfunctions. If the plug on the electric vehicle side is not securely inserted into the outlet, there is a risk that heat will be generated due to poor contact, and the worst situation of electric shock may occur.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a charging stand that maximizes the safety of electric vehicle drivers and passengers and protects the human body and devices.

  In order to achieve the above object, a charging stand according to the present invention is a charging stand having a charging device for supplying power to a battery mounted on an electric vehicle equipped with a data logger. Branching into a rectifying / smoothing circuit and a magnet switch circuit. The rectifying / smoothing circuit includes a control circuit having an electronic lock circuit and a charging method selection circuit, a display unit for displaying the state of the control circuit, and the magnet A circuit for opening / closing a magnet switch provided in the switch circuit, a safety door opening / closing detection circuit for detecting an opening / closing state of a safety door for isolating the charging device, and an opening / closing state of a power supply switch for charging Power supply switch open / close detection circuit and a plug for detecting an insertion state of the electric vehicle side plug into an outlet provided in the charging device A connection state detection circuit, and the magnet switch circuit includes the magnet switch for turning on and off the supply of charging power, a data logger circuit for recording the charge state, and a plug insertion state detection for detecting the insertion state of the plug. And the outlet provided with means. The safety door open / close detection circuit detects the safety door closed state, the plug insertion state detection means detects that a plug is inserted into the outlet, and the power supply switch open / close detection circuit detects the closed state. It is characterized in that power is supplied to the battery when the power is on.

  According to the charging stand of the present invention, charging is started after confirming various safety states in addition to the open / closed state of the safety door, the plug connection state, etc., resulting in malfunctions and the risk of overheating and electric shock Can be avoided.

FIG. 1 is a block diagram showing an example of a circuit configuration of a charging station according to the present invention.
The electric circuit configuration of the charging device constituting the charging station is to first receive AC 100V or 200V commercial power supply 11 and branch to two systems of rectification / smoothing circuit 13 and magnet switch circuit 14 via breaker 12. . The rectifying / smoothing circuit 13 is provided with a control circuit 17 having an electronic lock circuit 15 and a charging method selection circuit 16. The display circuit 18 branched after the rectifying / smoothing circuit 13 is provided with a display unit 19 for detecting and displaying the state of the control circuit 17. The display unit 19 includes a charging device as a power source. A power LED 20 that is lit when connected, a charging LED 21 that is lit during charging, and an abnormality LED 22 that is lit when an abnormality occurs are provided.

  Further, the control circuit 17 includes, as an input signal, a safety door open / close detection circuit 23 that detects an open / closed state of the safety door provided to isolate the charging device and prevent an erroneous operation, and a power supply for charging. A power supply switch open / close detection circuit 24 for detecting the open / close state of the switch, and a plug connection state detection circuit 26 for detecting the insertion state of the plug on the electric vehicle side into the outlet 25 provided in the charging device are provided.

  The control circuit 17 confirms that the electronic lock circuit 15 is in an unlocked state of the electronic lock, for example, a predetermined password is inputted to the numeric keypad, and the safety door open / close detection circuit 23 is connected to the safety door. Only when the closed state is detected, the plug connection state detection circuit 26 detects that the plug is inserted into the outlet, and the power supply switch open / close detection circuit 24 detects the closed state (ON). A chargeable signal is output to a switch opening / closing circuit 28 for opening / closing a magnet switch 27 provided in the magnet switch circuit 14, and the magnet switch 27 is closed to start charging.

  At the subsequent stage of the magnet switch 27, the outlet 25 having a plug insertion state detection sensor is provided via a data logger 29 incorporating a current sensor, and the plug 25 inserted into the outlet 25 is electrically connected via a cable. Electric power is supplied to the vehicle side, and the battery mounted on the electric vehicle side is charged. The state of charge is recorded in the data logger 29 and a data logger mounted on the electric vehicle.

  Thus, the state of the electronic lock, the state of the safety door, the insertion state of the plug into the outlet are confirmed, and only when these are in a chargeable state, that is, the control circuit 17 is ANDed from three places. Only when a signal is received, the magnet switch 27 is closed by turning on the power supply switch so that the battery can be charged. Therefore, only when a predetermined operation is performed, a current flows through the outlet and charging starts. Therefore, even if the outlet is inadvertently touched, there is no electric shock. Further, when the safety door is opened during charging, one of the AND signals to the control circuit 17 is cut off, so that the magnet switch 27 is opened by the action of the control circuit 17 and the power supply to the outlet is stopped. The Similarly, also when the plug is pulled out during charging, the control circuit 17 operates to open the magnet switch 27 and the power supply to the outlet is stopped.

  Therefore, it is possible to reliably prevent the driver and passengers from getting an electric shock and abnormal heat generation of the plug portion in the charging station that charges an unspecified number of electric vehicles. In an emergency, the power supply can be stopped by turning off the power supply switch or operating an emergency stop button provided separately, which improves safety and at the same time improves the Damage can also be prevented.

It is a block diagram which shows one example of a circuit structure in the charging station of this invention.
