Alternating current charging pile based on satellite navigation system

Abstract

The invention discloses an alternating current charging pile comprising a touch display, a card reader, a metering unit, a self-checking state indication unit, a trigger switch, a main controller and a satellite navigation system. The satellite navigation system is arranged inside the charging pile; the communication connection between a ground control center and an electric vehicle can be established by the satellite navigation system; the alternating current charging pile can be effectively managed by a monitoring center through the satellite; the clock synchronization among various charging piles can be realized and the unified time-sharing valuation function can be achieved; and by using the positioning function of the satellite navigation system, the monitoring center can effectively grasp the position of each charging pile and inform of electric vehicles, so that the electric vehicles can quickly position the positions of the charging piles for charging.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to an AC charging pile based on a satellite navigation system. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources and air pollution, and the increasing harm of global temperature rise, governments and automobile companies in various countries generally recognize that energy saving and emission reduction are the assisting directions for the development of future automobile technology. The development of electric vehicles will is the best way to solve the problem. With the promotion of electric vehicles, the construction of corresponding charging facilities is indispensable. At present, the main charging facilities include AC charging piles, chargers and motor replacements. [0003] The AC charging pile generally has a simple system, a small footprint, and is easy to install. It can be installed in electric vehicle charg...

Problems solved by technology

However, at present, the timing system of AC charging piles generally uses timing chips. Although the timing is accurate, it cannot be synchronized between different charging piles and between charging piles and the central control station. Therefore, it cannot be guaranteed that different charging piles have the same billing at the same time. method; the current communication mainly realizes the communication between the charging pile and the control center by connecting to the public Internet, and there is a problem of leaking secrets, but if a proprietary network is established, the cost will be too high; The location of charging piles cannot be found in the system, and it is difficult to reflect the respective geographic locations of each charging pile

[0004] The inventor found through research on the existing AC charging piles that the existing AC charging piles cannot guarantee the synchronization between the charging piles and between the charging piles and the central control station, and at the same time cannot accurately locate the geographical location of the AC charging piles
