Charging pile with multi-output function

Abstract

The invention relates to a charging pile with a multi-output function. The charging pile comprises a charging pile body and a control portion. The control portion comprises a master control unit, and further comprises a communication module, a monitoring panel, a digital electric meter, a man-machine interaction device, a card reader module, a storage module, a charging module group, an output filter module, a voltage control module, a modulating and current sharing module, a BMS monitoring module, a protective module and a miniprinter which are all connected with the master control unit. On the basis of an original charging function of a charger, a multichannel parallel and synchronous output efficient working mode is added, and eight output ports can work simultaneously at most; a harmonic filtration function is added, impact on communication due to harmonic waves of the charging pile is reduced, and the charging pile is high in reliability, excellent in maintainability, quick in response, high in transmission speed and suitable for wide-range popularization. Besides, the charging pile can charge multiple electric vehicles at the same time, can perform unified management on multiple outputs, and is scientific and coordinated, and capable of realizing ordered charging control.

Description

technical field [0001] The invention relates to a charging pile for electric vehicles, in particular to a charging pile with multiple output functions. Background technique [0002] The rising demand for energy in the world and the depletion of natural resources have brought new challenges to energy suppliers, industrial enterprises and consumers. It is imperative to use energy as efficiently and sustainably as possible, and electric vehicles have Such great energy saving potential. In the entire electric vehicle energy conversion chain, charging piles are a key link, and high-speed, low-loss power transmission must be achieved. [0003] The current electric vehicle charging piles generally adopt the design of one pile and one charging gun. Because charging takes a long time, more charging piles must be installed to expand the charging capacity, which will face many problems such as high equipment cost, space cost and maintenance cost. aspects of the problem. [0004] In ...

AI Technical Summary

Problems solved by technology

However, this method lacks the functions of voltage distribution and branch control of the charging process, which is greatly lacking in practicability and convenience.

[0005] When the high-power electric vehicle charger is running, it will generate large harmonics and pollute the power grid; this phenomenon is more serious when the multi-output charging pile is running, and the voltage control problem of each output port, the current sharing problem, and the operation control problem of the motor, Coordinated processing of multi-channel monitoring data, etc., need to be solved urgently
