Multifunctional alternating-current charging pile for electric automobile

Abstract

The invention relates to a multifunctional alternating-current charging pile for an electric automobile. The multifunctional alternating-current charging pile comprises a timer, a FLASH memory chip, a charging pile body structure, an AT89C51 chip, recognition equipment for the electric automobile and an infrared sensor array, wherein the charging pile body structure is used for charging a battery pack of the electric automobile; the infrared sensor array is used for detecting whether an automobile passes by adjacent roads or not; the FLASH memory chip and the recognition equipment for the electric automobile are used for identifying whether the pass-by automobile is an electric automobile or not; the AT89C51 chip is connected with the charging pile body structure, the timer, a liquid crystal display screen, the recognition equipment for the electric automobile and the infrared sensor array separately. According to the multifunctional alternating-current charging pile disclosed by the invention, the structure of the alternating-current charging pile can be optimized, and the functions of the alternating-current charging pile can be extended.

Description

technical field [0001] The invention relates to the field of AC charging piles, in particular to a multifunctional electric vehicle AC charging pile. Background technique [0002] The function of the driving motor of an electric vehicle is to convert the electrical energy of the power supply into mechanical energy, and drive the wheels and working devices through the transmission or directly. However, due to the existence of commutation sparks in DC motors, the power is small, the efficiency is low, and the maintenance workload is large; with the development of motor control technology, it is bound to be gradually replaced by brushless DC motors (BLDCM), switched reluctance motors (SRM) and AC asynchronous motors. Electric motors are replaced, such as caseless disc axial field DC series motors. [0003] The motor speed control device is set up for the speed change and direction change of the electric vehicle. Its function is to control the voltage or current of the motor, a...

Problems solved by technology

[0010] In order to solve the above problems, the present invention provides a multi-functional electric vehicle AC charging pile. The main body of the AC charging pile is built as a hardware platform. The main body of the AC charging pile is an optimized charging device, which uses electric vehicle identification equipment and infrared sensor The array separately counts the number of nearby electric vehicles and the total number of vehicles, and then displays the statistical results locally through the display device, so that the manager of the AC electric pile can decide whether to put the AC charging pile into sleep mode to save energy. Or decide whether to increase or decrease the number of AC charging piles, provide more valuable reference data, and avoid the situation that electric vehicles have no electricity to charge or waste electric energy.
