Professor Ahmed Gizil Ay, President of Inonu University:
We have been supporting electric vehicle battery management system projects for 10 years
Professor Serdar Altin, Head of the Physics Department at the College of Science:
We have been conducting scientific research to develop the performance of lithium iron phosphate batteries for four years
12 academics at Inonu University in the Turkish state of Malatya (center) have succeeded in increasing the efficiency and capacity of lithium iron phosphate batteries by 40 percent for use in electric cars, and developing a system that allows different types of batteries to be used together.
In an interview with Anatolia, Professor Ahmed Qizil Ay, President of Inonu University, said that they are working at the university on electric cars and battery systems.
Gizil Ay stated that they train students in the Electric Vehicle Technology Department of the Higher Vocational School; In order to educate workers in this field.
He added that they have provided support for the electric vehicle battery management system for 10 years as part of the scientific research project, and that they have succeeded in developing batteries and their management systems.
Kyzyl Eye said that they have supported 3 different projects at a cost of more than one million liras in recent years, and that scientists have implemented projects of the Scientific and Technological Research Corporation (TBİTAK).
He pointed out that the main goal of their work is to make prototypes of electric vehicles and to provide alternatives to them.
He explained that 12 academic researchers are cooperating in private laboratories and have achieved very good results, and that some projects have been completed and articles related to them have been published, and others are in the patenting stage.
For his part, Professor Serdar Altin, Head of the Physics Department at the College of Science, said that they have been conducting scientific research to develop the performance of lithium iron phosphate batteries for four years.
Altin noted that lithium iron phosphate batteries cannot be used in electric vehicles due to their poor performance with high electric currents.
He explained that they observed in their studies that the battery cathode material based on lithium iron phosphate could perform very well in high current applications if some structural modifications were made to it.
And he indicated that they found an increase in battery efficiency by 40% in high currents, especially in the rate of 4c, indicating that they had applied for a patent registration with the support of the university and are still continuing their studies.
Altin confirmed that they developed the battery by changing an amount of iron and using a different element, and that they conducted battery tests and performance changes checks by charging and discharging the battery 1000 times.
He expressed their desire to use the batteries they produced in the prototype of the electric vehicle that scientists at the Higher Vocational School and College of Engineering are implementing.
Manufacture of devices for the production of rechargeable batteries
Dr. Fateh Bolout, a member of the faculty of the Physics Department at the College of Science, said that they have produced some devices that are used in the production of rechargeable batteries of the 18650 and 21700 models used in electric vehicles.
Bolout added that they have developed a device for wrapping the electrodes used in batteries with their own capabilities according to their needs, and that this device performs the process of wrapping the electrodes with a length of one meter in addition to the drying process.
He stated that they are developing devices to be used in their own laboratory to suit their needs.
Creating a combination system to use different batteries together
As for Dr. Tyumen Karadag, a member of the faculty of the Department of Electrical and Electronic Engineering at the College of Engineering, he said that they have developed a system to manage the modular and adaptive battery used in electric vehicles.
Karadag indicated that they have completed the first model of the system within the framework of the Scientific and Technological Research Authority project, while the second model was completed with the support of the university.
He continued: “Batteries with different chemicals are used in electric cars, and the battery management system is specific to chemicals in them, so we defined all types of chemicals in batteries around the world, and then we developed a battery management system that can apply the foundations and methods of charging and discharging according to these chemicals.” .
Ismail Jan Dickman, a teacher at the Electric Vehicle Technology Department at the Higher Vocational School, said that they had prepared the programs and manufactured devices related to the battery management system and had filed for patent registration.
He added that this system determines the chemistry of the batteries when they are connected, and therefore it is not obligatory to adhere to the company from which the battery was purchased.
He added, “In the event that the electric vehicle battery is changed, the system that we have developed is suitable for the new battery. This system allows the use of batteries with different chemistry at the same time. It also allows the use of fast charging and discharging battery groups and slow charging and discharging batteries together.”
