Intelligent portable charging device and charging control method

Abstract

The invention discloses an intelligent portable charging device which includes a charging plug and an alternating current charging gun. The charging plug comprises a socket body and an electric leakage protection mechanism, the alternating current charging gun comprises a gun body and a gun head, the gun body is composed of two gun shells which are buckled oppositely and fixedly connected, a containing part is formed in the rear portion of the gun body, and a charging control guide circuit board is fixed in a cavity of the containing part. The gun head is fixedly arranged at the front end of the gun body in a sealed mode. According to the charging device, electric leakage protection is arranged in front of the plug, so that a subsequent whole line can be protected, and protection is more comprehensive and safer. Moreover, the electric leakage protection and charging control guide circuit board are arranged front and back separately, and a control box is not arranged in the middle of the cable any more, so that the possible damage or electric shock risk caused by treading of pedestrians or rolling of a vehicle on the control box during use is avoided. When in use, the control box isnot suspended below the plug, so that the virtual connection or disconnection caused by the traction effect on the plug is weakened, and the storage and the carrying by a user are more convenient.

Description

technical field [0001] The invention relates to the technical field of portable charging, in particular to an intelligent portable charging device and a charging control method. Background technique [0002] Portable charging devices often carried by electric vehicles generally include: 1) plug, common national standard plug, 2P+E (both poles with protective ground) three pins, and its rated current is divided into 10A or 16A; 2) cable is three core cable, between the plug and the control box; 3) the control box on the cable, leakage protection + charging control guidance function; 4) the cable between the control box on the cable and the charging gun, which is a four-core wire; 5) AC Charging cable, rated current is 10A or 16A. [0003] According to standard requirements, the maximum allowable length between the plug and the control box on the cable is 1.7m; if the distance exceeds 0.3m, the control box on the cable will be subjected to rolling during use. During use, if ...

AI Technical Summary

Problems solved by technology

If the distance between the plug and the control box on the cable reaches 1.7m, then during use, the control box on the cable is supported on the ground, and there are also big problems, such as accidental trampling by pedestrians, rolling by vehicles, wetness, etc., which will cause The control box on the cable is damaged, or it will bring danger to the user or third party personnel

[0004] Moreover, the entire structure includes plugs, cables, control boxes, and charging guns. The control box on the cable is in the middle of the cables, which is inconvenient for users to store.

During use, since the cable control box needs to communicate with the electric vehicle, the cable between the cable control box and the charging gun is a 4-core wire, and the overall product is large in size, heavy in weight and high in cost

Moreover, if the temperature monitoring function is integrated on the plug, 5-core wires (two communication wires of L\N\PE and the temperature sensor) are required to lead to the control box on the cable, further increasing the cost

[0005] Some products integrate the cable control box into the plug, but because the leakage protection and charging control guide function are integrated on the plug, the volume and weight become very large

Moreover, since the plug integrates leakage protection and charging control guidance functions, this requires power supply and communication between the plug and the electric vehicle, which will lead to long-distance use of 4-core wires (L\N\PE\CP), which will also have high costs. The problem, and the weight of the socket is very heavy, which will lead to unstable insertion status and cause safety hazards
