Embodiment 1

[0034] Embodiment 1 of the present invention discloses a charging pile, please refer to figure 1 , the charging pile includes a charging module 100, a power supply module 200 and a switching module 300, wherein:

[0035] The charging module 100 is used to process the alternating current obtained from the power grid, so as to charge the storage battery.

[0036] Wherein, in this embodiment, the charging module 100 is specifically a rectification circuit, that is, the charging module 100 realizes its function through a rectification circuit, such as figure 1 As shown, the rectification circuit includes a rectifier 110 and a DC filter 120 . The rectifier 110 is used to convert the AC power obtained from the grid into DC power; the DC filter is used to filter the DC power converted from the AC power to obtain filtered DC power for charging the storage battery. After filtering, the DC filter 120 can output the pure direct current required for charging the battery of the electric ...

Embodiment 2

[0045] Embodiment 2 of the present invention discloses another structure of the charging pile, please refer to figure 2 , in addition to the charging module 100 , the power supply module 200 and the switching module 300 of the charging pile in the first embodiment, it also includes an intelligent control module 400 . The intelligent control module 400 includes a meter 410 , a biller 420 , a human-computer interface 430 , a monitor 440 and a communicator 450 .

[0046] The meter 410 is connected with the charging module 100 and the power supply module 200, and is used for recording the charging parameter data when charging the storage battery, and for recording the power supply parameter data when supplying power to the grid.

[0047] Among them, the charging parameter data includes the values ​​of parameters such as current, voltage, battery capacity, and charging power when charging the battery; the power supply parameter data includes the values ​​​​of parameters such as cu...

Embodiment 3

[0059] Embodiment 3 of the present invention introduces the working process of the charging pile in various charging and power supply modes on the basis of Embodiment 1 and Embodiment 2.

[0060] 1) Fast charging mode

[0061] The electric vehicle battery is connected to the charging handle of the charging pile, and then the monitor monitors that the battery is connected, and displays it through the human-computer interaction device. At this time, the user selects the fast charging mode on the human-computer interaction interface, and the monitor receives the fast charging mode instruction issued by the human-computer interaction device, and responds to the fast charging mode instruction and sends an instruction to the switch to switch to the rectifier circuit , and then send an instruction to control the rectifier rectifier thyristor to charge the battery with pulse current, then control the battery to stop charging for a period of time, and then continue to charge the batter...

Abstract

The invention discloses a charging post which comprises a charging module, a power supply module and a switching module, wherein the charging module is used for processing an alternating current obtained from a power grid and charging a storage battery; the power supply module is used for processing a direct current obtained from the storage battery and supplying power to the power grid; the switching module is used for correspondingly triggering the charging module or the power supply module to work based on the charging or power supply requirements. According to the charging post, when the storage battery of an electric vehicle needs to be charged, the switching module is used for triggering the charging module to work, and the charging module is used for charging the storage battery of the electric vehicle, connected to the charging post by electric energy of the power grid; correspondingly, when the power grid needs to be supplied with the power, the switching module is used for triggering the power supply module to work, and the power supply module is used for supplying the power to the power grid by electric energy in the storage battery connected to the charging post. Therefore, the functions of charging the storage battery by the electric energy of the power grid and supplying the power to the power grid by the electric energy of the storage battery are achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent charging and power supply, and in particular relates to a charging pile. Background technique [0002] At present, the electric vehicle charging pile can only realize the function of using the electric energy of the grid to charge the storage battery of the electric vehicle, but cannot realize the function of using the electric energy in the battery of the electric vehicle to supply power to the grid. [0003] Therefore, it is an important subject in this field to study and provide a charging pile that can not only use the electric energy of the grid to charge the storage battery, but also use the electric energy in the storage battery to supply power to the grid. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a charging pile, which realizes the function of not only using the electric energy of the grid to charge the storage battery, bu...
