Problems solved by technology

[0005] The other is a high-configuration charging pile with ARM9 as the core, including the main body of the control board, the CPU microcontroller installed on the main body of the control board, and the power-down detection circuit and control guidance circuit electrically connected to the CPU microcontroller. , auxiliary power supply, RS485 ammeter communication interface, input and output interface, etc., and other lightning protectors, circuit breakers, contactors, ammeters, etc. need to be electrically connected to the controller separately. The electrical wiring of the charging pile with this structure is complicated and very It is easy to cause strong and weak current cables to be entangled with each other, and the device occupies a large space, and the heat loss of the integrated power module and the driving circuit is relatively large, which makes the equipment not only low in efficiency, large in size and heavy in weight, but also has serious EMC interference, which reduces the operation of the entire product. reliability and stability
Although the controller of this kind of charging pile is relatively advanced, the cost of the controller is high, and the software programming of the controller is complicated, the overall structure is loose, and the flexibility is relatively low. When charging piles are used on a large scale, cost control is a disadvantage.
[0006] In addition, most of the existing charging pile controllers use purchased onboard power modules, which often cause problems such as severe heat generation, inflexible board circuit layout, and poor EMC effects, making it difficult to meet higher standards.
To pass the EMC test, many manufacturers solve the problem by increasing the front-end filter capacitor and related inductance of the power module or adding a separate filter. This solution is not only costly, but also consumes a lot of standby power. Bring certain negative effects to consumers in normal use

Abstract

The invention provides a charging pile controller. The charging pile controller comprises an input and output module, an auxiliary power supply module, a controller module and an interface module; the input / output module is used for supplying power to the input / output module and the auxiliary power supply module; the auxiliary power supply module is used for supplying power to the controller module and the interface module; and the controller module is used for receiving data transmitted by the input and output module and the interface module and processing the data. The input and output module comprises an input port, a lightning protection circuit, a charging parameter metering unit, a main relay control circuit, an adhesion detection circuit and an output port. The input end of the auxiliary power supply module is connected with the lightning protection circuit, and the output end of the auxiliary power supply module is connected with the controller module and the interface module. The charging pile controller is low in cost, high in integration level, small in size, high in flexibility and reliability, rich in functions and simple in structure.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging pile controller. Background technique [0002] As an environmentally friendly, clean and energy-saving product that can achieve "zero emissions", electric vehicles are the development direction of the future automobile industry. The proportion of facilities in the whole vehicle is also higher and higher, and there is a development trend of more and more complex functions, more and more power, and higher and higher EMC requirements; the development of the above technologies makes the charging controller of electric vehicles The requirements for integration, reliability, energy saving and efficiency are getting higher and higher. [0003] At present, charging piles in the prior art are mainly divided into two types: [0004] One is a simple charging pile, which only has a simple charging function, does not have rich display functions, does not have the necessary...
