Solar charging pile for gas station

Abstract

The invention provides a solar charging pile for a gas station. The charging pile comprises a gas station ceiling, a roof, a wall surface, a solar cell panel, a Boost-type DC/DC circuit, a Buck-type AC/DC circuit, a DSP control system, an intelligent control switch, a change-over switch and a detection circuit, wherein the solar cell panel, the Boost-type DC/DC circuit, the Buck-type AC/DC circuit, the DSP control system, the intelligent control switch, the change-over switch and the detection circuit are suitable for an open space; a DC emitted from a photovoltaic cell array achieves the maximum power point tracking through a Boost circuit; meanwhile, a charging current of a storage battery is intelligently adjusted by adjusting the working state of the DC/DC circuit; the system can achieve AC and DC charging for an electric vehicle through switch control; and when a photovoltaic power generation system does not work or the charging current is not enough, the AC is automatically switched to charge the storage battery through an intelligent switch, and the condition that the storage battery is in a good working condition at any time is ensured. When a photovoltaic charging pile is connected to a grid for use on the photovoltaic roof of the gas station, the peak shifting regulation function of the power grid can be achieved through the storage battery of the electric vehicle; when the photovoltaic charging pile is in off-grid separate application, the capacity of the storage battery can be configured according to the actual condition.

Description

technical field [0001] The invention is a solar charging pile system installed at a fuel gas station, which is mainly applied to charging piles for various electric-driven vehicles. The invention belongs to the technical field of new energy and electric-driven vehicle charging. Background technique [0002] Electric vehicles use electric energy instead of petroleum as the power source, truly achieve zero exhaust emissions, and have the characteristics of cleanliness, environmental protection, and energy saving. It is a hot spot and trend in the development of the world's automobile industry. [0003] The solar charging pile installed at the gas station is to use the existing gas station as the construction site to provide energy supply for the battery of the electric drive vehicle, which is a key link in the development of the electric drive vehicle. The charging piles currently used in my country are divided into AC and DC charging piles. The AC charging pile is a charging ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of solar photovoltaic power generation and charging pile installed in the gas station, which is an electric-driven vehicle charging pile with solar power generation equipment, so as to solve the problem that the existing electric-driven vehicle charging pile can only use the AC grid for charging. It cannot fundamentally solve the problems of energy regeneration and environmental pollution. At the same time, photovoltaic charging piles can be installed off-grid in existing gas stations to provide emergency energy for electric vehicles.
