Charging pile energy management terminal

Abstract

The invention discloses a charging pile energy management terminal. The charging pile energy management terminal is characterized by comprising a mainboard, a distribution transformer RTU function module, a metering function module, a billing control function module, a hardware encryption module, a security equipment management module, a long-range channel and a short-range channel; the long-range channel comprises a 2G / 3G / 4G module and two RU45 interfaces, and a short-range communication interface comprises an RS485 communication interface or a CAN interface and a carrier wave / wireless module; a processor, an external expansion storage interface, an RS232 interface, an SPI, a USB Host interface, a chip interface, a positioning device interface, an audio output port and an RTC are fixedly arranged on the mainboard; the distribution transformer RTU function module is connected with a power distribution equipment control unit, and the power distribution equipment control unit is connected with power distribution equipment. By means of the technical scheme, the charging pile energy management terminal is provided with multiple long-range communication interfaces, has the capability of being compatible with various protocols and is low in networking cost, easy to maintain and low in failure rate.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to an energy management terminal for charging piles. Background technique [0002] It is only a matter of time before new energy vehicles eventually replace traditional fuel vehicles. With the rise of oil prices and the increasing shortage of energy sources, new vehicles aimed at energy conservation and environmental protection have sprung up like mushrooms. Electric vehicles stand out in the battle of many new energy vehicles due to their own advantages. In addition to technological breakthroughs and standard unification, related infrastructure construction must also be carried out simultaneously, such as roadside gas stations for fuel vehicles, efficient "car charging station" network and charging piles that manage these charging stations and provide convenient means of payment. Monitoring systems are a necessary prerequisite for the development of electric vehicles. [0...

Problems solved by technology

In order to implement the charging station operation and management system, it is necessary to configure their own interfaces and protocol conversion devices. It is difficult to ensure the consistency of communication at the position of the front-end processor. In order to cooperate with these devices, the master station must complete a large number of protocol identification and docking work, forming a network Complex structure, high failure rate, high networking cost and difficult maintenance
