Embodiment Construction

[0020] Embodiments of the multifunctional AC charging pile of the present invention will be described in detail below with reference to the accompanying drawings.

[0021]The driving motors of electric vehicles are divided into DC brushed, brushless, permanent magnet, electromagnetic, and AC stepping motors, etc. Their selection is also related to the vehicle configuration, use, and grade. In addition, the speed regulation control of the driving motor is also divided into stepless speed regulation and stepless speed regulation. There are electronic speed regulation controllers and no speed regulation controllers. Motors include hub motors, inner rotor motors, single motor drives, multi-motor drives, and combined motor drives.

[0022] Advantages of electric vehicles: The technology is relatively simple and mature, and it can be charged wherever there is electricity supply. Disadvantages of electric vehicles: the energy stored in the unit weight of the battery is too little, a...

Abstract

The invention relates to a charging pile AC electric energy meter calibration apparatus. The apparatus comprises a timer, a FLASH storage chip, a charging pile main body structure, an AT89C51 chip, an electric automobile identification device, an infrared ray sensing array, a calibration power source, a data acquisition unit, a data processing unit and a man-machine interaction unit. The charging pile AC electric energy meter calibration apparatus is a calibration apparatus which is based on a real-time pulse comparison method and realizes calibration of a calibrated DC electric energy meter in a virtual power output mode. The calibration power source is composed of two independent power sources. The calibration apparatus solves the problems of quite high rated currents and rated voltage values, large dynamic scope, quite high frequency response performance requirements of the calibrated DC electric energy meter, can comprehensively and accurately evaluate metering performance of the calibrated DC electric energy meter, and facilitates traceablility of an electric energy metering characteristic to an upper national standard.

Description

technical field [0001] The invention relates to the field of AC charging piles, in particular to a verification device for an AC electric energy meter of a 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 cu...
