Charging pile and charging regulation and control method

Abstract

The invention provides a charging pile and a charging regulation and control protection method. The charging pile comprises a base, a support, an electric appliance box arranged at the top end of the base, a control device arranged in the electric appliance box and a heat dissipation device located in the control device, and the support is arranged at the top end of the base and extends towards the two sides; at least four charging arms are arranged on the two sides of the support, sliding structures are arranged in the charging arms, charging ends are connected to the sliding structures, the driving device drives the sliding structures to move in the charging arms, and the charging ends are adjusted to stretch out and draw back by adjusting the positions of the sliding structures in the charging arms. One end of each sliding structure close to the support is connected with a spiral cable, and the other end of the spiral cable is connected with the control device. Whether the electric vehicle in the idle position can be charged or not is judged by adjusting the output current of the charging end in charging, meanwhile, the sliding structures are controlled to move outwards to drive the charging ends to stretch out for charging, and the safety of the charging pile in the charging process is guaranteed while the utilization rate of the charging pile is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a charging pile and a charging regulation and protection method. Background technique [0002] With the shortage of oil resources and the development of battery technology, a new generation of energy-saving and environmentally friendly vehicles represented by electric vehicles has become an inevitable trend in the development of the automotive industry. The development of electric vehicles has increased the demand for public charging devices. Electric vehicle charging piles are mainly floor-mounted and wall-mounted. Most of the car charging stations are floor-mounted. The current floor-mounted charging piles mainly have the following problems: 1. In order to achieve waterproof and anti-collision functions, floor-mounted charging piles need Set a concrete base that is higher than the ground by a certain size, so it takes up a lot of space; 2.

[0002] With the shortage of oil resources and the development of battery technology, a new generation of energy-saving and environmentally friendly vehicles represented by electric vehicles has become an inevitable trend in the development of the automotive industry. The development of electric vehicles has increased the demand for public charging devices. Electric vehicle charging piles are mainly floor-mounted and wall-mounted. Most of the car charging stations are floor-mounted. The current floor-mounted charging piles mainly have the following problems: 1. In order to achieve waterproof and anti-collision functions, floor-mounted charging piles need Set a concrete base that is higher than the ground by a certain size, so it takes up a lot of space; 2. Due to space constraints, a charging pile can usually only charge 1-2 cars at the same time, which affects the use of charging piles Efficiency; 3. Due to the floor type, the cooling holes on the control cabinet of the charging pile can generally only be installed along the side of the control cabinet, and the air in the control cabinet can only form convection along the cabinet wall, which leads to heat generation in the center of the control cabinet The device cannot dissipate heat sufficiently, which affects its service life; 4. Since the installation position of the floor charging pile is relatively low, it is easy to be damaged by criminals

Although this existing technology changes the traditional floor-standing type into an overhead type, which saves the cement base and installation space occupied by the traditional floor-standing type to a certain extent, since the charging plug is arranged inside the cantilever through the winding reel, the cantilever is made of "H" The cable is made of channel steel, so that the cable is not protected, and it is easy to corrode when exposed to the outside for a long time, and it is prone to failure during subsequent use.

And when multiple charging plugs are charged at the same time, it is easy to cause the charging pile to be overloaded, and different electric vehicles have different power requirements, so the charging pile cannot be adjusted in a targeted manner, which may easily cause the charging pile to malfunction and affect the use
