Throughout Europe, there is a growing trend toward electrification of public transportation, which is also gaining ground in Poland. This green approach to urban transportation not only significantly reduces air and noise pollution, but also contributes to the fight against climate change. From this blog post, you will learn more about the role of advanced technology such as PLCs and SCADA systems in optimizing electric bus charging stations. You'll also learn details about the project to work with the company supplying energy to the charging points and the innovative solutions we offer in controlling and managing the process. Read on!
In recent years, in response to global climate challenges and pollution, many European cities have been working hard to reduce emissions in public transportation. An increasing number of cities are choosing to replace traditional vehicles with electric buses, due to the numerous benefits of this investment. One of the most important advantages comes from the fact that electric vehicles do not emit exhaust fumes, resulting in cleaner air. This, in turn, translates into improved living comfort for residents and public health. Low-emission transportation also means lower greenhouse gas emissions, which contributes to the fight against climate change. In addition, electric public transportation is much quieter.
The electric bus market in Poland is growing rapidly, as confirmed by an analysis by the Polish Chamber of Electromobility Development. According to statistics from the first half of 2023, the number of registered electrobuses in our country has reached 856 units. Among cities with the largest number of such vehicles, Warsaw is in the lead, with a fleet of 148 electric buses. Poznań takes second place with 86 electrobuses, followed closely by Cracow, with 78 electric buses. By 2028, Polish cities with populations over 50,000 will be required to incorporate at least 30% zero-emission or biomethane-powered vehicles into their fleets. This is part of a broader effort to reduce CO2 emissions in transportation, in line with EU regulations and the Electromobility Act, which calls for emissions from heavy-duty vehicles to fall by 40% by 2040.
Electric vehicle charging stations
In one of the European cities, we collaborated with a company that provides energy to charging points for zero-emission buses for the public transport enterprise. Our efforts were focused on delivering a solution consisting of a temperature measurement and control system for four compact charging stations. Each of these stations was equipped with key technical components, including high and low voltage distribution stations, a transformer, uninterrupted power supply systems of 48VDC, remote control and fire protection systems, as well as air conditioning installations.
An extremely important aspect of this project is the advanced control technology, including our PLC controller mTRON T in combination with temperature sensors for air conditioning systems. This system allows for precise monitoring of different areas of the station, such as transformer rooms or high and low voltage distribution boards, enabling their independent and efficient operation.
Control over the management system is achieved through a fully customizable touchscreen with manual operation and user levels, tailored for both operators and moderators. The home screen provides the user with a clear overview of the HVAC control status in the transformer room, the 48VDC room, and the low and high voltage distribution installations.
The project used our PLC controller mTRON (705001)
The system we delivered was integrated with the existing SCADA system. This integration allows for continuous environmental condition monitoring through temperature alarms, ensuring optimal operation of the equipment. Secondly, the functionality of remote PID setting adjustments provides operators with the flexibility to modify system parameters in response to changing operational conditions. Another important aspect is the capability for rapid response to fires and other emergency situations, offering an additional level of protection. Lastly, with the registration of logins, the client has full control over who has access to the system and what changes have been made, enhancing their ability to maintain the continuity and security of the entire system.
