Abstract

The invention discloses a charging pile. The charging pile comprises an output interface used for being connected with a rechargeable battery, a power supply input unit used for being connected with a power supply grid, a plurality of charging units connected with the power supply input unit and the output interface, and a main controller, wherein the charging units are connected in parallel, the main controller is connected with the charging units and used for receiving required currents from the rechargeable battery, and controls each charging unit to convey the first currents to the output interface, and the product of the first currents and the number of the charging units is equal to the required currents. According to the charging pile, the problem that charging equipment in the prior art is low in charging speed is solved, and the effects of shortening charging time and increasing the charging speed can be achieved.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to a charging pile. Background technique [0002] As the global auto industry is facing huge challenges of energy and environmental issues, there has been a broad international consensus on the development of new energy electric vehicles, the electrification of automotive energy and power systems, and the promotion of the strategic transformation of the traditional auto industry. At present, my country has issued many policies to support and guide the rapid development of the electric vehicle industry. The government intends to accelerate the improvement of the competitiveness of the domestic electric vehicle industry, shorten the maturity period, and realize the "curve overtaking" of the foreign automobile industry. The development of electric vehicles has entered a critical period, where opportunities and challenges coexist. [0003] The power supplement of electric ve...
