specific Embodiment 1

[0027] This embodiment is directed to the electric vehicle guidance circuit specified in the national standard GB / T20234.2-2011 figure 1 As shown, a specially designed AC charging device for electric vehicles.

[0028] Such as image 3 As shown, this embodiment proposes an AC charging device for an electric vehicle. The AC charging device includes power lines L and N for providing electrical energy; a power supply interface connected to the power lines L and N; The second on-off switch K7 on L and N; when the second on-off switch K7 is closed, the electric energy of the power line L, N is transmitted to the power supply interface, and the power supply interface is charged and can charge the electric vehicle. When K7 is disconnected, the power supply interface is not live.

[0029] The AC charging device of this embodiment includes a controller, a first on-off switch K6, L and N power supply loop state detection circuits, and a DC power supply. Among them, the controller controls t...

specific Embodiment 2

[0035] This embodiment is aimed at those specified in the national standard GB / T20234.2-2011 figure 1 The electric vehicle steering circuit shown and figure 2 The electric vehicle pilot circuit shown (or other electric vehicle pilot circuits with a voltage divider resistor set between the signal line CP and the ground line PE) is a specially designed electric vehicle AC charging device that can both figure 1 The electric car shown can charge figure 2 Electric car charging shown.

[0036] Such as Figure 4-6 As shown, the AC charging device includes all the content of the specific embodiment 1, which will not be repeated here. At the same time, the AC charging device is also equipped with the detection point 1 of the internal guidance circuit of the electric vehicle. The detection point 1 is connected to the DC power supply or the PWM signal output terminal of the controller through the resistor R1 and the on-off switch S1. The detection point 1 is connected to the power supply ...

Abstract

The invention discloses an electromobile alternating current charging device and a charging control method thereof. The charging device comprises a power supply loop state detection circuit, the connection state of a power supply interface and a power line is controlled according to a conduction state of a power supply loop, no electric shock risk exists, and the charging device is simple to operate. The charging device also comprises a guidance circuit detection point in an electromobile, a controller is used for judging whether the electromobile connected with the power supply interface is provided with a guidance circuit or not according to a voltage signal of the detection point, if yes, the connection state of the power supply interface and the power line is controlled according to the voltage signal of the detection point, if not, the power supply loop state is switched to detect the circuit, and the connection state of the power supply interface and the power line is controlled by detecting the conduction state of the power supply loop. According to the electromobile alternating current charging device and the charging control method thereof, the electromobile which is provided with or not provided with the guidance circuit can be compatible, various types of charging devices are unnecessarily arranged in a charging station, cost is saved, the charging device is high in application rate, the electromobile can be charged by arbitrary one of the charging devices, and a user is convenient to charge.

Description

Technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle AC charging device and a charging control method thereof. Background technique [0002] With the increasing awareness of environmental protection and energy conservation, electric vehicles are gradually being favored because they are powered by on-board power sources, which can solve the environmental pollution and high energy consumption of fuel-fuel vehicles. The charging of electric vehicles is a problem that people are very concerned about, and it is related to the popularization and promotion of electric vehicles. [0003] Due to different manufacturers of electric vehicles, their internally designed pilot circuits are also different, as long as they comply with national standards. The so-called pilot circuit is a circuit used to detect the connection status of the power supply interface of the charging device and the electric vehicle in real ...
