Embodiment Construction

[0020] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0021] A new type of non-vehicle intelligent DC charging pile, see figure 1 , figure 2 , including electric field type 3D gesture input and LCD display, that is, man-machine interface, card reader, control part and AC / DC conversion part. Among them, the AC / DC conversion part is the actuator that generates DC power for electric vehicles. It is powered by BMS auxiliary power supply, The intelligent voltage resonant switching power supply and its protection unit are composed of BMS auxiliary power supply and intelligent voltage resonant switching power supply, which are intelligently controlled by the control part to generate DC power supply and protection unit suitable for the BMS power supply requirements of electric vehicles and the charging requirements of electric vehicle power batteries. It realizes the overvoltage, overcurrent and l...

Abstract

The invention relates to a non-vehicle-mounted intelligent DC charging pile, and the charging pile comprises an electric-field type 3D gesture input and LCD display interface, a card reader, a control part, and an AC / DC conversion part. The AC / DC conversion part is an executing mechanism for generating DC power supplied to an electric car, and consists of a BSM auxiliary power supply, an intelligent-type voltage resonance switching power supply, and a protection unit. The card reader achieves the confirmation of a user identity and a payment function. The control part consists of an RISC main control unit, a vehicle type recognition system, a BMS communication system, a GPS module, a comprehensive measurement module, and a cloud access unit. The vehicle type recognition system achieves the visual recognition and confirmation of the type of a to-be-charged car, and transmitting the recognition results to the RISC main control unit, thereby determining a power supply voltage level needed by the BMS of the car, and controlling the BSM auxiliary power supply of the AC / DC conversion part to generate direct current at the power supply voltage level for reliably supplying power to the BMS of the electric car. The image information of the vehicle type recognition system is uploaded to a remote cloud terminal through a cloud access unit.

Description

technical field [0001] The invention belongs to power electronics technology and digital signal processing technology, relates to cloud access function technology, in particular to a new type of non-vehicle intelligent DC charging pile. Background technique [0002] All over the world, with the depletion of traditional resources such as oil and the requirements of environmental protection, the world's automobile industry has entered a period of comprehensive transportation energy transformation, and the development of electric vehicles has become a technical route for realizing transportation energy transformation that has achieved a high degree of international consensus.
