Stating that they have trained professionals in the Electric Vehicle Technologies Department of the Organized Industrial Zone (OIZ) Vocational School (MYO), they have supported the electric vehicle battery management system within the scope of the Scientific Research Project for 10 years, Kızılay said that they have been successful in the development of battery and battery management systems. expressed.
Prof. Dr. The Red Crescent said:
“In recent years, we have supported 3 different projects over 1 million lira. Our professors have also carried out TUBITAK projects. The main goal of our work is to make prototypes of electric vehicles and present their alternative. 12 research academicians collaborated in their own laboratories and achieved very good results. Some projects have been completed. Some articles have been published, some are at the patent stage. “
Head of the Physics Department of the Faculty of Science and Letters, Prof. Dr. Serdar Altın explained that they have been doing scientific research to improve the performance of lithium iron phosphate batteries for 4 years.
Pointing out that these batteries cannot be used in electric vehicles because their performance at high currents is not very good, Altın said, “In our study, we have seen that lithium iron phosphate based cathode material performs very well in high current applications with structural modification. We found an increase of 40 percent in high currents, especially 4C. We made our patent application with the support of our university, and the process continues. ” used the expressions.
Stating that they developed the battery by changing the amount of iron with a different element, Altın said, “In the battery tests, we examined the performance changes by charging and discharging the battery 1000 times. While there was no structural change, we achieved a very good efficiency in battery performance when operating at high currents. we want to use it in a prototype electric vehicle. ” he spoke.
They made devices used in the production of rechargeable batteries
Faculty of Arts and Sciences, Department of Physics, Assoc. Dr. Fatih Bulut explained that they manufactured some devices used in the production of 18650 and 21700 rechargeable batteries that can be used in electric vehicles, and continued as follows:
“We developed the film coating device of the electrodes used in the batteries according to our needs with our own means. This device both covers the electrodes and performs the drying process. We develop devices for use in our own laboratory when needed. This device we developed can cover 1 meter long electrodes.”
Integrated system that will allow the use of different batteries together
Noting that they have completed the first prototype of the system within the scope of the TÜBİTAK project and developed the second prototype with the support of the university, Karadağ said, “In electric vehicles, batteries of different chemistries are used and management systems are specific to these battery chemistry. We recognized all the battery chemistry in the world and made a management system that can apply charge and discharge methods according to them. . ” said.
“We made the software and hardware of the management system of the batteries and applied for a patent. The system determines the chemistry of the connected battery. Any company does not have to be tied to the company from which the battery purchased the battery, or if the battery of the vehicle changes, the system we make is compatible. It provides the opportunity to use in a coordinated manner. It enables fast and slow charging and discharging battery groups to be used together. A system that enables the use of superior properties of different battery chemistries together.
