Power-driven vehicle charging pile with solar power generation device

Abstract

The invention relates to a power-driven vehicle charging pile with a solar power generation device. The charging pile is composed of 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. A direct current outputted by a photovoltaic cell array is processed by the Boost type DC/DC circuit to realize maximum power point tracing; and the working state of the DC/DC circuit is adjusted to adjust a charging current of a storage battery intelligently. On the basis of switch controlling, an electric vehicle can be charged by alternating currents or direct currents. When a photovoltaic generation system does not work or charging currents are not sufficient, alternating-current switching is carried out to charge the storage battery by the intelligent switch, so that the storage battery can work in a good state all the time. When the photovoltaic charging pile is used in a grid-connected state at a household photovoltaic roof, the peak staggering adjusting function of the grid can be realized by the electric vehicle storage battery. When the photovoltaic charging pile is used separately in an off-line state, the capacity of the storage battery can be configured based on practical situations.

Description

technical field [0001] The invention relates to a charging pile system for electric-driven vehicles using solar power generation equipment, which is mainly applied to charging piles for various electric-driven vehicles.

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, which is an electric-driven car charging pile using solar power generation equipment, so as to solve the problem that the existing electric-driven vehicle charging pile can only be charged by the AC grid, which cannot fundamentally solve the problem. Problems of energy regeneration and environmental pollution. At the same time, photovoltaic charging piles can be installed off-grid in various parking bays or highways without service areas to provide emergency energy for electric vehicles.
