Significantly cheaper operation, less possibility of breakdowns and environmentally friendly operation – these are, among other things, the characteristics of heavy trucks developed by Electromega Kft. Schneider Electric’s liquid-cooled frequency converter has been used for vehicles already used for waste collection and logistics
Thanks to the cooperation of Electromega Kft. and Schneider Electric in Debrecen, domestically built trucks with electric drive chains are already on the roads. The first fully electric truck with a total weight of 40 tons was put into operation at the Audi site in Győr last autumn, and the first four electric garbage trucks built by Electromega Kft. Were handed over this spring in Hajdú-Bihar county.
The history of Hungarian-developed electric trucks began at the University of Debrecen, where originally racing cars were powered by an electric motor, and as a result of a 2010 tender for electric-powered dump trucks, the technology was tested on much larger vehicles. The development was successful, and the process, patented in 2014, was purchased by the owner of Electromega, so the company began building electric trucks. Schneider Electric was also involved in the project, using the company’s liquid-cooled frequency converter to control the electric motor.
The frequency converter is actually the “guardian angel” of electric motors. they can be adjusted without gear, but they also play an important role in current protection, temperature protection and overload prevention. The electric trucks built by Electromega feature the Schneider Electric Altivar 71 frequency converter, which can perform even the most demanding starting and speed control tasks. Among other things, the device is able to handle an extended frequency range for high-speed motors and offers extremely precise torque and speed control.
“Typically, our product is used in buildings and electrical control cabinets, which with the creativity of Electromega we have now been able to use in a completely new area. This collaboration is a very good example of “out of the box” thinking and perfectly shows that it is worth being open to ideas that seem bold at first, as a serious new market may open up for us in the future thanks to this development, “he said. Gábor Molnár is an engineer-salesman at Schneider Electric.
“Electric-powered heavy trucks have a number of advantages over their traditional counterparts. i, while in the case of vehicles using diesel the amount is about 3600 forints. Although the initial investment cost is higher for electric-powered trucks, the total cost of ownership can be lower in up to 8 years, but in some cases even shorter than in conventional vehicles. In addition, it is worth taking into account that while the diesel engine of a truck has 167 rotating and moving parts, the engine of the vehicles we develop has less than 35, which means a much lower risk of failure, “emphasized Ruben Bántó, Chief Operating Officer of Electromega Kft.
Hungarian-developed electric trucks not only attract attention with their more favorable maintenance costs and “greener” operation, but also provide much more information about their own operation to the operators. available, for example, on how the energy consumption of each energy cell changes or, for example, how it operates, how many times the frequency converter is switched on.
