Control system of control panel of AC charging pile

Abstract

The invention provides a control system of a control panel of an AC charging pile. The system comprises a controller, an indicating lamp, a matrix keyboard, a colored LCD interface, a single-color LCD parallel port, a local upgrade interface, a temperature detection unit, a power down detection unit, an RTC circuit, an external FLASH memory, an output relay and a CAN communication interface, the controller control a charging process as well as related signal collection and protection, the indicating lamp, including four controllable indicating lamp interfaces and one normally ON indicating lamp interface, is connected with the controller, and the matrix keyboard including a 4*4 keyboard is connected with the controller. The control system is lower in the cost, abundant in functions and flexible in configuration, and has functions including metering, charging, system detection, system data query, system data leading-out, background communication, indication via the indicating lamp and sound prompt via a buzzer; and via the background communication functions, an Ethernet connection background, a GPRS / 3G / 4G connection background, a WIFI connection background, a Bluetooth connection background, a CAN connection background and the like are supported.

Description

technical field [0001] The invention relates to the field of intelligent charging facilities for electric vehicles, in particular to an AC charging pile control board control system. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources, and the increasing harm to the air caused by fuel vehicles, governments and automobile companies in various countries generally recognize that electric vehicles will be the direction of development. Nowadays, electric vehicles with similarities and differences appear one after another, but the technology for charging them in various places when electric vehicles are running is not mature enough, and it is also very inconvenient, such as electric vehicle charging stations, personal parking spaces or large public parking lots and other charging places for electric vehicles. The charging operation is not simple and convenient enough. Electric vehicle intelligent AC charging pile is a power...

Problems solved by technology

[0005] The other is a high-configuration charging pile with ARM9 as the core. Although the controller is more advanced, the cost is high, the programming is complicated, and the flexibility is relatively low. When charging piles are used on a large scale, cost control is a disadvantage.
