technical field

The utility model relates to the technical field of electric vehicles, in particular to an electric vehicle charging pile.

Background technique

An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Working principle: battery--current--power regulator--electric motor--power transmission system--driving the car (Road).

In order to meet the development of electric vehicles and the needs of supporting use, electric vehicle charging pile products have emerged as the times require, and have also been continuously developed.

The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle.

Up to now, my country's electric vehicle charging stations are mostly limited to electric buses or internal group vehicles, and a service network of charging stations for different users has not yet been established.

The representative charging stations that have been built or are under construction are:

In 2006, BYD built Shenzhen's first electric vehicle charging station at its headquarters in Shenzhen.

In 2008, the first centralized charging station in China was built during the Beijing Olympic Games, which can meet the power battery charging needs of 50 pure electric buses.

In October 2009, Shanghai Electric Power Company invested in the construction of Shanghai Caoxi Electric Vehicle Charging Station, which is the first electric vehicle charging station with commercial operation functions in China. At the end of 2009, Beijing Shouke Group completed the construction of China's first pure electric passenger car demonstration charging station including a complete smart micro-grid in Jianxiang Bridge.

On December 31, 2009, the first batch of electric vehicle charging stations (pile) put into operation by China Southern Power Grid was completed and put into operation in Shenzhen, with a construction scale of 2 charging stations and 134 charging piles.

On March 31, 2010, the Tangshan Nanhu Charging Station of the State Grid Corporation of my country was completed and put into operation.

In the prior art, the charging pile does not have an automatic settlement function, and the user needs to go to the service desk to pay and issue an invoice after charging is completed. In the cold winter, the user also needs to get off the car to go to the service desk, and return to the car parking place after paying the fee, which brings inconvenience to the user and affects the user experience.

In addition, due to the high cost of charging piles, the price of a charging pile is generally tens of thousands or even hundreds of thousands, and it is mainly installed in the parking lot. The existing charging piles are at risk of being stolen. Ten thousand or even hundreds of thousands, mainly installed in the parking lot, the existing charging piles have the risk of being stolen, and due to the high cost, the general parking lot only sets a small number, but as electric vehicles are more and more widely used , the demand for charging piles is increasing, and the charging piles fixed in some fixed parking spaces cannot meet the needs of the public, but if one charging pile is installed for every one or two parking spaces, it will cause an oversupply situation, which will cause a waste of resources , especially the charging piles in the open air environment are easily damaged by wind and sun, which increases the charging cost.
