Problems solved by technology

[0002] At present, electric vehicles based on new energy, such as electric vehicles, electric boats, and drones, have been widely used. There are many charging path planning methods for electric vehicles in the existing technology, but they are basically only suitable for direct power supply. Charging piles or charging stations, and the charging path planning of the existing electric vehicles are mostly based on detecting the remaining power of the power battery of the current electric vehicle to find the next rechargeable charging station for the user to choose. When it takes only one charge to reach the destination, there is no reasonable and effective full-range power path planning method
Energy storage charging piles have the advantages of slow storage and fast discharge, but because the energy storage of energy storage charging piles or charging stations is limited, idle time is not equal to effective charging time with sufficient energy storage, and there is currently no effective reservation method

Embodiment 1

[0222] The types of charging piles in the entire road network in this embodiment include existing energy storage charging piles, and may also include existing grid-directly-supplied charging piles that are directly provided by the grid to charge electric vehicles. The power supply source of the energy storage charging pile can be one or more of new energy power generation or complementary energy storage that purchases electricity from the grid. New energy power generation includes solar power generation and wind power generation. The DC charging of the electric vehicle through the energy storage charging pile is referred to as fast charging; the energy storage charging pile has a control module that automatically switches the working mode. When an electric vehicle is connected to the charging pile for charging, the control module controls the switching to the charging pile discharge work. mode; when no electric vehicle is connected for charging, the control module controls to a...

Embodiment 2

[0232] The charging piles of the whole road network in this embodiment are the same as those in Embodiment 1.

[0233] A method for planning a power path of an electric vehicle compatible with an energy storage charging pile. The electric vehicle in this embodiment is an electric vehicle, and includes the following steps:

[0234] 1) All charging piles in the road network are connected to the dispatching system platform through a wireless communication network or a wired communication network, and the electric vehicle client is connected to the dispatching system platform through a wireless communication network or a wired communication network;

[0235] All the charging piles on the road network submit the state information of the piles to the dispatching system platform, including: the location of the charging pile, the type of the charging pile, the rated power E of the energy storage battery of the charging pile 额 , The real-time occupancy status of this charging pile, if ...

Embodiment 3

[0253] The charging piles of the whole road network in this embodiment are the same as those in Embodiment 1.

[0254] Compatible with the electric vehicle power path planning method of the energy storage charging pile, the electric vehicle in this embodiment is an electric vehicle, and also includes a method for adjusting the vehicle in front, the steps are as follows:

[0255] 1. Assuming that before the reservation of electric vehicle i, there are vehicles in front that reserve charging paths respectively according to the method of embodiment 2, and generate respective full-course reservation plans. The vehicle in front of this embodiment refers to: a charging pile that has at least one shared charging pile with the electric vehicle i, referred to as a shared pile, including a car that has been reserved but has not yet set off when the electric vehicle i is expected to arrive at the shared pile; it also includes a reservation After departure, but when the electric car i is ...

Abstract

The invention discloses an electric vehicle electric quantity path planning method compatible with an energy storage charging pile, and the method comprises the following steps: 1), a whole-network charging pile submits the state information of the pile to a scheduling system platform, and an electric vehicle applies for a reservation from the scheduling system platform before departure; 2) a shortest path is searched from a departure place to a destination; (3) the scheduling system platform judges whether the reserved distribution electric quantity of one or more charging piles of the electric vehicle on the path meets the endurance requirement of driving to the destination or not; 4) if yes, a whole-course reservation scheme is generated; and 5) if not, the shortest path is eliminated, the shortest path is searched from the rest paths, and executed circularly from the step 3) until all the paths are traversed. According to the method, electric vehicle whole-course electric quantity path planning can be realized, fusion use of the energy storage charging piles and the power grid direct supply charging piles is realized by utilizing arrival time matching, meanwhile, charging scheduling is performed on the vehicle through a scheduling system platform, and full application of whole-network charging pile resources, especially the electric quantity of the energy storage piles is realized.
