Bio
Dr. STOYAN GISHIN in graduated chemistry and physics at the “St. Kliment Ohridski” University of Sofia, Bulgaria, in 1968. He has a PhD degree in electro-technological problems of batteries. He is the author of more than 140 scientific articles and 30 patents on battery problems published in the USA, Russia, England, Germany, Czech Republic, and other countries.
Since 1968 he has been a fellow of the Technical University of Sofia, in charge of a battery lab.
In 2012 he created in Bulgaria the company “Battery center Europe” and is currently its President. In 2016 he created another company, “Elektro-technology Ltd.”, active on innovations in start-ups.
He has presented at several international battery conferences in Bulgaria, Russia, Germany, Greece, USA, Japan, Serbia, China, etc.
He was awarded with a gold medal and a certificate for his highly effective electro-technological study by the Exhibition of the achievements of the people’s economy – (VDNKH) in Moscow, Russia.
He was awarded a gold medal and certificate at the European patent exhibition in 1999 for one of his patents. At the exhibition “Technology 2000” organized during the 56-th international technical fair in Plovdiv, Bulgaria, he was awarded with a gold medal and certificate for block formation of batteries with pulsed current and computer control of the process (patented).
He is member of the Bulgarian Accreditation Service since 1999, Member of the Technical Committee for Accreditation of “Testing Laboratories”, of the Commission for Accreditation of Testing Laboratories, and Lead Assessor for Battery Testing.
He was awarded a Certificate of honor and a gold medal by the Dean of the Faculty of Electrical Engineering of the Technical University of Sofia for his contributions to scientific research activities in 2005.
He was also awarded a Certificate of honor and a silver medal by the Rector of the Technological University of Sofiya for his outstanding scientific, research and administrative contributions in 2011.
Stoyan Gishin was invited by the Chinese-Amerian company “Zhejiang Meineng Electric Co. Ltd, Anji” and the Technological Institute of Ninbo, and visited five times China for industrial studies and testing in regular manufacturing of AGM batteries for electric vehicles.
He was awarded by the President of the Republic of Bulgaria and listed in the Golden book of the Bulgarian inventors.
In 2024 he was listed in the Book of the 50 Bulgarian inventions which have changed the world.

Innovative intelligent systems and electrical technologies have been developed in the production of lead accumulators and batteries with pulsed current with computer control and registration of the parameters and results of electrochemical processes – amount of electricity, electricity, electric voltage, duration of the processes, current impulses and others. , Criteria have been developed that specialized software programs with fuzzy logic measure, calculate, compare with the main parameters of the dynamic state of various electrochemical processes and automatically determine the duration of current pulses in order to conduct them in an energy and ecologically efficient manner. The main advantages are Speeding up electrochemical processes and productivity, saving electricity, improving their electrical characteristics, increasing their service life, significantly reducing the conduct of harmful electrolysis processes and, accordingly, releasing acid aerosols that pollute the working environment and others. IS and electrical technologies have been verified at the level of RLT 7, 8 – competitive production in Bulgaria and China and can be sold worldwide. IS and ET are innovative solutions for the production and charging of accumulators and batteries for vehicles, RES, energy storage and others and are protected by patents in Bulgaria and other countries.
