Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging piles, and particularly to a modularly assembled new energy vehicle charging pile. Background Art

[0002] As is well known, an electric vehicle charging pile is a device that provides electric energy for electric vehicles. It is connected to the power grid through the power input end, and the output end is connected to the vehicle through a charging plug to achieve electric energy transmission, enabling the electric vehicle to store sufficient power to support its operation. At the same time, it supports functions such as timing, charging, and power monitoring, and ensures the stability and safety during the charging process of new energy vehicles through internal safety components, playing an important role in the charging method of new energy vehicles.

[0003] The deficiencies of the prior art are that currently, new energy vehicle charging piles generally have an integrated structure. The integrated design requires overall maintenance when a fault occurs. The damage of ordinary components may require replacing the core module or even the whole machine, resulting in a long maintenance cycle and poor economy. For example, a power module failure may force the entire charging pile to stop operating, with low operation and maintenance efficiency. At the same time, the existing integrated charging piles have deep coupling between hardware and software, making it difficult to separately upgrade the charging power or communication protocol. When facing the iteration of fast charging technology, it is often necessary to discard the whole machine equipment, resulting in serious waste of resources. Moreover, due to the integrated structure design of the existing new energy vehicle charging piles, the connection of various electrical components inside is too compact, and a single component failure may cause system-level downtime, affecting the normal use of the charging pile, and it is very troublesome and time-consuming to maintain.
