Description

1 TARIFF Parking Lot Management Automatic Charging System for Electric Vehicles TECHNICAL AREA 5 The invention is a multi-point and queue-controlled automated charging system for electric vehicles. It is related to charging systems. The invention specifically enables charging ports for multiple electric vehicles at different parking locations. enabling the charging requests of vehicles connected to the system to be processed in advance. by detecting and charging vehicles according to the connection order and / or defined priority criteria. and receive electrical energy from a central power source in a shared queue Automatically charges the vehicle whose turn it is via the linear power line to the connection point. It relates to a multi-point electric vehicle charging system that directs traffic. 15 The invention allows the user to charge their vehicle by leaving it in a suitable parking spot. After establishing the connection, the charging unit may discharge or the charging sequence may be interrupted. without having to wait by the vehicle for it to arrive, the vehicle will be available when it's their turn. It allows for automatic charging. 20 STATE OF THE ART With the increasing adoption of electric vehicles, parking lots, shopping malls, and workplaces will become more accessible. 25 in areas such as centers, residences, recreation facilities, gas stations and similar places The need for electric vehicle charging infrastructure is steadily increasing. In current practices, electric vehicle charging stations are mostly located in designated and fixed parking areas. They are being installed at various points, and the number of vehicles that can be served simultaneously depends on the charging unit. It may be limited by the number of outputs it has and its available power capacity. Especially 30 In areas with high usage, charging points being fully charged means other users This causes it to wait for a suitable charging point to become depleted. 2 When the charging point runs out, the user picks up their vehicle from the parking area. taking it to the empty charging point and reconnecting the charging connection This may be necessary, especially when vehicles are parked for extended periods. This requires users to follow the charging queue in parking lots; it leads to a waste of time, 5 This can lead to increased vehicle mobility and difficulties in use. In addition, each parking spot is equipped with an independent, high-power charging unit. the implementation; power converters, power electronics components, electrical infrastructure, installation and this increases maintenance requirements and consequently raises system costs. This can be the reason. In current systems, the charging demands of multiple vehicles are centralized in a queue. managing the process of ensuring charging ports are available in advance at the parking locations of vehicles. This can be accomplished and the available charging power can be connected to the vehicle next in the charging queue. 15 The need arises to automatically redirect it to that point. Specifically, vehicles connected to the system are placed in a charging queue according to their connection times. FIFO (First In), which is based on the principle of receiving and charging the first connected vehicle first, Charging is done automatically according to the First In (First Out) principle. This is implemented by users waiting in line in front of the charging point or when it's their turn to charge. a solution to eliminate the need to reposition vehicles It provides. Therefore, multiple electric vehicles can be charged at different parking spots in the same area. 25 where connections can be made in advance, connected vehicles in a charging queue managed, the connection of the vehicle in turn to the energy supplied from the central power source. it is automatically transferred to that point and after the relevant charging process is completed a multi-point, queue-managed and automated system where energy is directed to the next vehicle An electric vehicle charging system is needed. 30 3 THE PURPOSE OF THE INVENTION The main purpose of the invention is to charge multiple electric vehicles at different parking locations. pre-arrangement of connections and queue management of the vehicles in question a multi-point charging system that allows for automatic charging based on its principle 5 to reveal. Another purpose of the invention is to detect the charging demands of electric vehicles connected to the system. The vehicles are placed in a charging queue, and in the preferred application, the first vehicle to connect is prioritized. FIFO (First In, First Out) system that prioritizes charging 10 Its principle is to automatically manage charging processes. Another purpose of the invention is to allow the user to charge their vehicle by leaving it in a suitable parking spot. after establishing the connection, the charging sequence or the discharge of the charging point Without needing to monitor it, the vehicle automatically starts charging when its turn comes. The aim is to ensure that it is done. Another purpose of the invention is to allow the user to park their vehicle when it's time to charge. by eliminating the need for the vehicle to move from one charging point to another. The aim is to enable charging to be carried out at the point where the vehicle is parked. User 20 There is no need to remove the charging socket from the vehicle whose battery is dead and transfer it from that vehicle to your own vehicle. The transactions are completed without delay. Another purpose of the invention is to complete the charging process of a vehicle and / or to ensure the specified charging time is reached. Once the criterion is met, the transfer of power to the relevant connection point is terminated, 25 energy is automatically transferred to the connection point of the vehicle next in the charging queue. The goal is to ensure proper guidance. Another aim of the invention is to provide each parking spot with an independent high-power charging unit. by reducing the need to establish a central power and charging infrastructure, multiple parking points 30 shared use by the parties and efficient management of existing charging capacity to provide. 4 DETAILED DESCRIPTION OF THE INVENTION The invention essentially consists of at least one linear power line (1), at least one stationary charging unit (2), linear 5 multiple that have an electrical and / or communication connection with the power line (1) making the charging connection with the connection point (3) and the electric vehicle (5) It includes at least one charging connector (4) that provides.
