Six-star pile charging pile

Abstract

The invention provides a six-star pile charging pile, and belongs to the technical field of charging piles. The six-star pile charging pile comprises a charging pile main cabinet, a plurality of charging guns electrically connected with the charging pile main cabinet through gun lines, and first to third double-loop ammeters connected with the interior of the charging pile main cabinet. According to the invention, flexible charging and discharging control of two electric vehicles can be realized at the same time, ordered charging and discharging control of different electric vehicles can be realized through interlocking limitation between each group of cascade contactors, the maximum charging and discharging power is ensured not to exceed the limitation, the safety of the charging and discharging process is ensured, the problems that a bidirectional charging pile is low in daily utilization rate, long in idle time and long in investment return period are solved, and the problems of automatic, ordered and flexible charging and discharging scheduling and control of the bidirectional charging pile are solved.

Description

technical field [0001] The invention belongs to the technical field of charging piles, in particular to a six-star pile charging pile. Background technique [0002] Vigorously developing electric vehicles is an important guarantee for realizing the electrification transformation of my country's transportation energy, an important fulcrum for promoting the transformation of my country's power system to a renewable energy power system, and the only way to realize my country's 3060 "carbon peak" and "carbon neutral" strategies. According to the "Energy Saving and New Energy Vehicle Technology Route" figure 2 .0”, the sales volume of new energy vehicles in China will reach 40%-50% of the total vehicle sales in 2030, the number of vehicles will reach 80-100 million, and the energy of the batteries carried will reach 5 billion kWh electricity or so. [0003] Large-scale electric vehicle charging is both a challenge and an opportunity for the power system. From the perspective of...
