Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle accessories, and in particular to an electronic block-type V2G direct current charging pile. Background Art

[0002] Under the vehicle lightweight technology route, in order to reduce the weight of the vehicle body and R&D costs, some electric vehicle companies have abandoned the on-board charger and only retained the DC charging interface, which will rapidly promote the development of DC charging pile technology. With the development of smart grids, the current DC charging piles with single energy transmission can no longer meet the requirements. DC charging piles with V2G functions can participate in the peak-shaving and valley-filling of the power grid, improve the operation of the power grid, and enhance the safety of power grid electricity use.

[0003] Existing V2G products are insufficient:

[0004] (1) Non-integrated design

[0005] The current V2G DC charging pile topology is as follows Fig.10 As shown in the figure, a non-integrated design is adopted. The charge and discharge control unit is an independent module that interacts with the network connection unit, status indicator light, multi-function energy meter, safety protection, vehicle communication, electrical control, and charge and discharge power supply module. Each functional unit is designed independently and must be electrically connected through external communication and other means. Therefore, the development cost is high and the installation space requirement is large.

[0006] (2) Integrated design

[0007] In an integrated design, when one of the circuits is damaged, the entire circuit board needs to be replaced, resulting in high maintenance costs.

[0008] (3) V2G charging pile has a single function combination

[0009] The current V2G charging pile has both charging and discharging functions. When customers only need the charging function or the discharging function, the charging and discharging control module cannot be replaced and cannot be arbitrarily combined into charging mode or charging and discharging mode.

[0010] Therefore, it is very important to obtain an electronic block-type V2G DC charging pile that can solve the current problems of high cost, large installation space requirement, and single functional combination of V2G charging piles based on integrated design. Summary of the invention

[0011] In order to solve at least one of the above technical problems, the present invention provides an electronic block type V2G DC charging pile, including an electronic block substrate, an electronic block socket electrically connected to the electronic block base, and an electronic block, on which pins are fixed, and the electronic block is detachably connected to the electronic block socket through the pins, and the electronic block includes an electronic block type bidirectional charging and discharging DC-DC conversion unit, an electronic block type unidirectional charging DC-DC conversion unit and an electronic block type filtering unit.

[0012] The electronic block type bidirectional charge-discharge DC-DC conversion unit, the electronic block type unidirectional charge DC-DC conversion unit and the electronic block type filter unit are all plugged into the electronic block substrate through pins. The electronic block type filter unit can be electrically connected to one of the electronic block type bidirectional charge-discharge DC-DC conversion unit and the electronic block type unidirectional charge DC-DC conversion unit by means of a switch.

[0013] The electronic block filter unit and the electronic block unidirectional charging DC-DC conversion unit electrically connected thereto are fixed to the electronic block socket via pins to realize the charging function.

[0014] The electronic block filter unit and the electronic block bidirectional charge-discharge DC-DC conversion unit electrically connected thereto are fixed to the electronic block socket through pins to realize the charge-discharge function. It also includes an electronic block functional unit, including an electronic block voice unit, which is electrically connected to the electronic block socket to realize the voice function. The electronic block functional unit can also be other functional units such as a lighting unit and an indication unit.

[0015] It also includes an electronic block detection circuit and a controller. When the electronic block is fixed to the electronic block socket, the collected analog voltage value is input to the AD port of the controller after the amplification circuit. The controller determines the type of the connected electronic block according to the collected voltage value, so as to match different programs and realize different circuit functions. The present invention has an electronic block hardware detection circuit, which can quickly realize program matching and function conversion.

[0016] Compared with the prior art, the advantages of the present invention are: the present invention has a simple structure, integrates functional units on an electronic block, and then places multiple electronic blocks on a printed circuit board, that is, an electronic block substrate, to solve the problems of cost and installation space. Since the present invention adopts the form of an electronic block, when a circuit therein is damaged, there is no need to replace the entire circuit board, thereby reducing maintenance costs; and the present invention can select charging function or discharging function according to customer needs, realize different combinations, facilitate product upgrades and renovations, and solve the current problems of high cost, large installation space requirements, and single functional combination of V2G charging piles.
