The research collaboration between the Department of Electrical Engineering, Diponegoro University and PT Hartono Istana Teknologi (POLYTRON) continues to show significant progress. Following initial discussions on August 13, 2025, this research project entered an important phase on November 6, 2025, with the official handover of EV batteries from POLYTRON to the Electrical Engineering Department of UNDIP. The assistance, in the form of a 27Ah Battery Pack and charger unit, was handed over by company representatives Min Nursandi, an alumnus of Electrical Engineering UNDIP, and Evanus Yupiter.
This research involves UNDIP Electrical Engineering students, namely Ayodya Raja Yudha, Umara, and Tegar Riyanto from the undergraduate program, as well as Rofiq Maududi from the graduate program. This research was supervised by two lecturers from the UNDIP Electrical Engineering Department, Trias Andromeda, S.T., M.T., Ph.D., and Ir. Teguh Prakoso, S.T., M.T., Ph.D., who accompanied the team from the concept development to the system implementation stage.
The main focus of this research is the development of a fast charging system for two-wheeled electric vehicles, with the concept of optimal power utilization. The fast charging system developed is designed based on the principle that the power for charging EV batteries comes from the remaining power from household power usage. Thus, fast charging can be done without disrupting household electricity operations, because the system only utilizes the excess power that is still available.
The handover of EV batteries from POLYTRON provides important support for the testing and validation phase of the designed system. This device allows the team to conduct experiments directly, so that the research results can be developed more accurately and applicably.
With a project completion target of February 2026, this collaboration is expected to produce innovations that are beneficial for the development of electric vehicle technology in Indonesia, particularly in improving efficiency and implementing fast charging processes in household environments. This collaboration not only strengthens UNDIP’s relationship with national companies such as POLYTRON, but also provides students with applied research experience, in line with the needs of the ever-evolving technology industry.
