Embodiment Construction

[0016] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 As shown, the present invention provides an electric vehicle charging pile, including: a DC charger, a controller, an energy storage module, a coupling circuit and a control interface;

[0018] As the core module of the entire charging pile, the controller is used to first detect whether there is an electric vehicle using the charging pile, and when it is detected that there is no electric vehicle using the charging pile, it controls the internal state of the control interface to be in a connected state during the low power consumption, so that Connect the DC charger to the energy storage module, so that the DC charger can charge the energy storage module; and when it is detected that there is a...

Abstract

The invention relates to a charging pile for an electric car, and belongs to the technical field of electric cars. The charging pile for an electric car comprises a direct current charger, a controller an energy storage module, a coupling circuit and a control interface. The charging pile for an electric car utilizes the technology integrated with the direct current charger and the energy storage module to avoid capacity limitation when the energy storage module is independently used, so that the charging is not influenced by the electric quantity of the energy storage module and energy storage can be performed during the low ebb period. Therefore, the charging pile for an electric car can effectively and reasonably utilizes a power grid, reduce the harmonic wave distortion rate and reduce power grid pollution.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle charging pile. Background technique [0002] The vigorous development of electric vehicles has led to the construction of a large number of charging facilities. There are two types of charging facilities: fast charging and slow charging. Fast charging uses DC charging piles. The existing DC charging piles are divided into two technical solutions: the first solution is to use the energy storage module to charge the battery, similar to charging a mobile phone with a power bank. The second solution is to use the method of combining AC / DC and DC / DC to convert alternating current into controllable direct current to charge the vehicle. [0003] The DC piles adopting the above-mentioned first scheme have capacity limitations. If the energy storage module is in a low battery state, the charging pile cannot charge the car. [0004] Adopting the second solu...
