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.
