Description

AN ELECTRIC VEHICLE CHARGING SYSTEM
Field of the Invention
The invention relates to an electric vehicle charging system, developed for the purpose of charging electric vehicles at their location, comprising a roaming electric charger vehicle that feeds itsel f and the battery groups in the cargo with solar energy and that can also be recharged per se .
Known State of the Art
Rapidly developing technology, population growth and rising globali zation cause the rapid depletion of high-energy and non-renewable energy resources , especially oil products . Vehicles , in particular, have a very high share in terms of energy consumption . Although the movement of vehicles can be driven by electric motors , the use of internal combustion engines is quite common today . The main reasons for the situation are the low battery capacity of electric vehicles and the limited number and location of charging stations .
The ef ficiency of internal combustion engines is low and their use leads to serious problems for human health and the environment . With the use of these engines , the harmful gas emissions ( especially CO2 emissions ) generated are quite high compared to the amount of fuel consumed . In addition, the decrease in fossil fuel reserves and the increase in demand constitute an economic disadvantage . Due to the aforementioned facts , the automotive industry has been shi fting to the production and use of electric vehicles .
Charging electric vehicles is usually carried out via charging units in fixed positions . For charging operations , the location of the charging stations and an application/contact with the operator company must be established, the vehicle must be taken to the charging stations and the battery charging process must be carried out by remaining in that position for a certain period of time . Charging stations are investments that cannot be easily updated and due to their fixed location, they prevent the easy charging o f electric vehicles and prevent the widespread use of electric vehicles as well .
There are documents in the art describing the various systems that have been developed for charging electric vehicles .
The patent document no . US20160023562A1 may be referred as an example for the current state of the art . The aforementioned document deals with a portable charger for charging electric vehicles . The unit of the said document itsel f requires transportation by a vehicle or by a vehicle needs to be charged and fed of f the grid/another vehicle with combustion engine per se .
Another example of the current state of the art is the patent document No . US 8963481B2 . The aforementioned document features a charging service vehicle and modular batteries for charging electric vehicles . Combustion engine vehicles are used in the mobile charging units (battery group ) o f the said document , the mentioned vehicles can charge with generator support with combustion engine power and the vehicles being a standard commercial vehicle with combustion engine .
Since the combustion engine alternators to be used by the portable charging units , which can be an alternative to the fixed units in the aforementioned documents , do not provide charging conditions in the desired time and compliance , there may be a large additional load on the electricity grids and the vehicles that provide mobility are themselves working with combustion engines , the aforementioned documents do not provide solutions to the problems in the art . In addition, the fast charging conditions and the trans fer of power from the combustion engines di f fer and the battery technologies of the new electric vehicles introduced to the market today provide di f ferent charging conditions . In addition, the transmission of an energy equal to a household consumption of one-week or more into an electric vehicle battery group within a period of 30-45 minutes causes a serious loading on the grid and constitutes a signi ficantly greater amount than the electric energy that can be obtained from combustible engine power of a vehicle to be generated in the same periods .
Another example of the current state of the art is the patent document No . CN107985104A. The aforementioned document features a charging system for charging electric vehicles . It is stated in the document that due to the low battery capacity, low charging li fe and high cost , a solution is found with mobile and permanent batteries for the vehicle of the document . However, the vehicle of the said document is fed from the grid and in addition, all resources of the vehicle are exhausted after the charging process . Therefore , the system has to recharge itsel f by moving the vehicle per se . This situation creates a disadvantage in cases where more than one electric vehicle needs to be charged and the charging time is long due to the AC charging of the vehicle . In addition, considering that today ' s vehicles have batteries with an energy capacity of 20- 120 kWh, it can be understood that it is not possible to feed the said batteries quickly only by relying on solar panels on the vehicle ( 150-400 W x number of panels ) . In addition, the system subj ect to the said document is related to the urgent charging process in case of emergencies and there is no fast charging feature in the system in question .
Another document that can be referred as an example for the current state of the art is the patent document no . WO2015160937A1 . This document is related to the installation of a charging kit on commercial ( fossil fuel ) vehicles operating on motorways and highways and the vehicle is not fully roaming . Further, the vehicle of the said document does not have the potential to go/reach every vehicle that needs to be charged . It is not possible for tow trucks , which has a trailer starting from 13 . 6 m length, to reach an electric vehicle that needs to be charged in an urban environment and it can only serve as a mobile charging vehicle while its on a break at a speci fic point on a highway . The trailer and tow truck speci fied in the document in question are disadvantageous due to their si ze even i f they serve only for the electric vehicle charging process and the problem of CO2 emission lingers . In addition, the 30- 110 m2 solar panel is not suf ficient considering the power trans fer and the amount of electrical energy trans ferred for the fast charging of the vehicle .
Therefore , there is a need for a charging vehicle for electric vehicles and a charging system including this vehicle , which can be charged by feeding of f a clean energy source and providing fast charging, which has the ability to go to every location in an urban environment , especially in cities .

In an embodiment of the invention, the electric charger vehicle (1) carries 50-125 kWh of energy while the cargo is fully loaded.
The electric vehicle charging system of an embodiment of the invention and the charging processes related to said system are shown in Figure-1. Figure-1 illustrates an electric charger vehicle (1) (pickup) with a cargo area consisting of 50-80 kg and/or 12kWh-30 kWh battery groups (2) from lithium- ion battery groups, which are the most suitable choice according to cost efficiency, energy efficiency, heat performance, weight and cycle criteria, an electric vehicle (3) , a mini solar power plant (13) and a smartphone/ terminal (12) comprising a mobile application. The charging processes carried out with the charging system of the invention in more detail comprises the following; charging process (4) of electric vehicle (3) via battery group (2) , charging process (6) of the battery group (2) in the cargo area via the retractable solar energy panels (5) on the electric charger vehicle (1) , charging process (7) of electric vehicle (3) via solar panels (5) located on electric charger vehicle (1) , charging process (8) of the electric charger vehicle (1) via the solar panels (5) on the electric charger vehicle (1) , charging process (9) of the battery group (2) via the mini solar power plant (13) and charging process (10) of electric vehicle (3) via mini solar power plant (13) .
