Design Considerations for a Low-Voltage Scalable Battery-Test Laboratory †

István Lakatos Gábor Szakállas

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

The rapidly developing battery industry entails the need for battery testing. Battery charging and discharging require time-consuming testing, so it is necessary for the battery testing laboratory to take effective personnel protection, area isolation, fire and smoke extraction, remote monitoring, and other measures. The software plays a crucial role in optimizing the scheduling of battery test labs. It might start testing on a small scale initially, but later, as demands on the lab grow, an appropriate software will be needed to schedule testing for optimal usage. This article presents the design considerations and steps of a test lab for testing and analyzing low-voltage battery cells and packs, including all components, safety requirements for safety circuitry, and the purpose of laboratory testing for industrial and research purposes.

Self-Driving Vehicle Sensors from One-Seated Experimental to Road-legal Vehicle

Ernö Horváth Zoltan Szeli Peter Koros Gábor Szakállas Peter Gulyas Zoltan Pusztai

Publication Name: Ines 2020 IEEE 24th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2020-07-01

Volume: Unknown

Issue: Unknown

Page Range: 97-101

Description:

Our university is determined to research and educate self-driving and autonomous technology. These two field require different necessities and attitude. In his paper we would like to summarize the migration from a road-legal vehicle to a self-developed, one-seated vehicle. We will describe the challenges of the migration process and of course how to overcome these challenges. The current paper also proposes recommendations and use-cases regarding self-driving vehicle sensory system.

Research of vehicle parameter and sensor systems necessary to control autonomous vehicles

Dániel Pup Gábor Szakállas József Polák

Publication Name: 2018 14th IEEE ASME International Conference on Mechatronic and Embedded Systems and Applications Mesa 2018

Publication Date: 2018-08-27

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

Our long-term goal is to implement autonomous vehicle control functions on a standard vehicle. At first we started with the investigation of the steering, which is a crucial area of the control of autonomous vehicles. As a part of the program, vehicle dynamical measurements were carried out on a Nissan Leaf electric vehicle equipped with a sensor system.

Maximizing battery life and usable capacity with battery management system in electric vehicles

Zoltan Szeli Gábor Szakállas Ferenc Szauter

Publication Name: Proceedings of the ASME Design Engineering Technical Conference

Publication Date: 2017-01-01

Volume: 9

Issue: Unknown

Page Range: Unknown

Description:

In terms of the electric vehicles is an important issue of sizing a battery pack. The designer must take account of parameters such as cost, weight and durability. We can optimize these parameters with the help of a battery management system with integrated active cell balancing function. The article describes the development of a battery management system that developed by the Research Centre of Vehicle Industry at Széchenyi István University, Gyor, Hungary.
