Multi-vehicle one-pile shared charging system and implementation method thereof

Abstract

The invention provides a multi-vehicle one-pile shared charging system and method. The multi-vehicle one-pile shared charging system comprises a charging pile, a main controller and a plurality of charging branches, the charging branch comprises a charging gun and a contactor; the plurality of charging branches are connected with the main controller through a connection bus; and the connection bus includes a metering device for detecting a voltage. According to the system, the main controller controls the on-off of the contactor to realize the switching of the charging guns, the cost is low, a plurality of vehicles in adjacent parking spaces can share one charging pile, and the vehicles are charged in sequence according to the gun insertion sequence, so that the repeated installation of the charging piles can be reduced, the space cost is saved, and the instantaneous power load of a community is reduced. And the charging pile does not need to communicate with a CAN system at the vehicle end, the structure is simple, and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a multi-vehicle-one-pile sharing charging system and an implementation method thereof. Background technique [0002] Under the vigorous promotion of the country, new energy vehicles are becoming more and more popular. As a supporting product for new energy vehicles, AC charging piles have received more and more attention from government departments. In the prior art, the current AC charging piles that accompany the vehicle are generally equipped with an AC charging pile for a new energy vehicle, and the owner uses his own charging pile to charge the car. This has brought about the following problems: 1. The deployment of charging piles is dense, and a charging pile needs to be installed for each new car, which will cause waste of resources; and the parking spaces in the community are generally tight, and it is difficult to realize one charging pile for one vehicle. 2. The...

Problems solved by technology

This has brought about the following problems: 1. The deployment of charging piles is intensive. Every time a new car is added, a pile needs to be installed, which will cause waste of resources;

2. The off-duty peak period is also the peak period for new energy vehicle charging, and the power capacity of the community is limited, and intensive charging will lead to large power fluctuations in the community in a short time
