Charging method of new energy vehicle

Abstract

The invention provides a charging method of a new energy vehicle. According to the charging method of the new energy vehicle, through the space not influencing parking and driving at the upper portionof the vehicle, charging equipment is installed and arranged, through free running of a main unit at an interconnection track, vehicle charging requirements can be met simply by putting a proper amount of charging equipment with a low simultaneous utilization rate, the corresponding amount of main unit equipment is reduced, the method for reducing investment and also not influencing the chargingrequirements and parking space use is achieved, investment of equipment and facilities like a cable and a track which are long in service life and are not likely to have a fault are put in the stage when the new energy vehicles are not popularized, an interface is reserved at the charging position at each parking space, according to the requirement quantity of the charged vehicle, the proper number of the charging main units is set, even if all the vehicles are the new energy vehicles, since the vehicle charging demand is asynchronous in time, finally, the charging equipment with the same amount as the number of the parking spaces does not need to be put, scientific calculation is conducted according to data, proper charging equipment high in price and short in service life does not need to be put, the vehicle can be automatically charged within a valley duration of a grid, and the operation cost can be saved to the greatest extent; meanwhile, the resource investment is saved, the timeof a user is shortened, and the energy investment is saved.

Description

technical field [0001] The invention relates to the charging field of new energy vehicles. Background technique [0002] With the development of new energy vehicles, electric vehicles or hybrid vehicles with motor drive are more and more accepted by consumers. The functional requirements of charging are not only in centralized charging places like gas stations, but also in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots. The input end of the charging facility is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. At present, charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. , The display sc...

Problems solved by technology

[0004] Traditional car charging piles are mostly fixed on the ground. In large parking lots with relatively compact parking spaces, charging piles will have some impact on parking, driving and walking. It is even difficult to have a nearby space that does not affect parking, driving and walking. Install charging piles, which limits the popularization and mass implementation of charging piles in large parking lots

[0005] Although new energy vehicles are the future development trend, at present, there will still be a large number of non-new energy vehicles for a long time, so in large private parking lots, it is necessary to arrange flowers (non-continuous) and layout charging without affecting the neighborhood pile very difficult

In terms of universal and comprehensive installation, because individuals generally do not spend money first to buy products that are not sure when they will be used, and they are not sure when they will be used, so universal installation is currently more difficult to achieve

Even if the government or enterprises fund free installation, some people may disagree with the installation, because it will affect his parking, driving and walking at present.

Even if everyone agrees to install it, at the current stage there will be a large number of charging piles that are idle and useless, causing great waste. When they need to be used, the charging piles may no longer be usable and need to be replaced. It is popularized in the parking lot of large private parking spaces, and it also restricts the popularization of new energy vehicles

[0006] In addition, the above-mentioned charging pile method also faces great difficulties in realizing the automatic unmanned charging function, because the ground space of large parking lots is limited, generally there is a horizontal charging distance, and it is difficult to realize the unmanned automatic charging operation mode

In addition, the "simultaneous utilization rate" of all parking spaces charging at the same time is very low, so that a large number of charging piles will be idle, and the effective utilization rate of resources is low
