Problems solved by technology

The traditional double-gun charging pile generally adopts the average power charging method whether it is single-gun or double-gun charging at the same time. This will slow down the charging speed by half for charging only with a single gun, and the user’s waiting time will be correspondingly longer. , the utilization rate of charging piles is also affected accordingly

Embodiment 1

[0058] Such as figure 2 , 3 As shown in the figure, a control method for double-gun charging piles with automatic switching between single and double guns. The charging mode of the double guns is sent to the charging control unit by the billing unit, and the charging control unit controls the power distribution according to the working mode sent by the billing unit. The unit and the charging module output different powers.

[0059] At the beginning, the double-gun charging pile system is powered on and initialized, and the double-gun charging pile system performs a self-check. If the system fails, it will wait for the fault to recover and repeat the self-check. If the system is normal, it will enter the standby state.

[0060] If someone comes to charge a charging gun, and the billing unit detects that the other charging gun is not working, it will send a wheel charging working mode to the charging control unit. After the charging control unit receives the corresponding com...

Embodiment 2

[0065] Such as figure 2 , 4 As shown, a control method for double-gun charging piles with automatic switching between single and double guns. The charging mode of the double guns is sent to the charging control unit by the billing unit, and the charging control unit controls the power according to the working mode sent by the billing unit. The distribution unit and the charging module output different powers.

[0066] At the beginning, the double-gun charging pile system is powered on and initialized, and the double-gun charging pile system performs a self-check. If the system fails, it will wait for the fault to recover and repeat the self-check. If the system is normal, it will enter the standby state.

[0067] If someone comes to charge a charging gun, and the billing unit detects that the other charging gun is not working, the billing unit of the charging gun will send the charging control unit the wheel charging mode, and the charging control unit will receive the corre...

Abstract

The invention discloses a double-gun charging pile system with the function of automatic single-double-gun switching and a control method thereof in the field of new energy vehicle charging. The system is composed of a charging cabinet and two split piles. Billing units are arranged in the split piles. An AC-DC charging module, a power allocation unit, two charging control units and two power distribution units are arranged in the charging cabinet; and an alternating-current input terminal is connected with the power allocation unit by the AC-DC charging module. In addition, the method includes: carrying out initialization; carrying out self checking and entering a standby state; and detecting charging states of the pair of guns and entering a single-gun alternating charging mode or a dual-gun simultaneous charging mode based on different states and the like. In the single-gun alternating charging mode, the billing units carry out charging; and in the dual-gun simultaneous charging mode, the billing units send mode switching commands and a charging control unit completes self checking and then enters a charging state. According to the invention, problems of low usage efficiency ofthe dual-gun charging pile and slow single-gun charging by a user are solved; the utilization rate of the charging pile is improved; and a quick charging experience is provided for the user with single gun for charging.

Description

technical field [0001] The invention relates to the field of new energy vehicle charging, in particular to a dual-gun charging pile system and a control method for automatic switching between single and double guns. Background technique [0002] With the continuous development of China's economy, people's lives are getting richer and richer. Public transportation cannot meet the travel needs of most people, and people are buying more cars. At present, most cars are generally powered by gasoline. However, most of the components of gasoline after burning pollute the atmosphere, which makes the air pollution problem more and more serious. However, with the increase of people's awareness of environmental protection, and the Chinese government vigorously promotes new energy With the development of the automobile industry and vigorous subsidies for the new energy automobile industry, people's attention to new energy automobiles continues to increase. At present, pure electric veh...
