Adaptive heating with the use of braking energy
Lumikko’s regenerative braking systems are a transformative technology for public transportation, offering several key benefits:
- Energy efficiency: The kinetic energy recovered during braking is converted into electrical energy, which is stored in the system and used in a controlled manner for heating to maintain the cabin temperature as stable as possible. This reduces the need for additional energy sources, as well as the consumption of fossil fuels and greenhouse gas emissions. The system enables the utilization of over 70% of braking energy for heating during the winter season.
- Cost savings: By storing and reusing energy that would typically be lost, regenerative braking systems help public transit agencies cut down on their energy expenses. This includes lower maintenance costs over time due to reduced wear and tear on traditional braking systems.
- Enhanced passenger comfort: Travelling in a heated tram during the winter frost is significantly more comfortable.
Lumikko aims to contribute to building a more sustainable future by providing innovative and responsible thermal management solutions for public transportation.
Regerative braking system in a nutshell
Lumikko’s regenerative braking system is an innovative and environmentally friendly solution that utilises the energy generated by tram braking and …and stores it in an innovative brake resistor system integrated into the HVAC device. The system converts kinetic energy into electrical energy that can be used to heat the cabin or stored for later use. In this way, the system reduces the energy consumption and emissions of trams and improves passenger comfort.
The Lumikko regenerative braking system is in use in all Finnish tram cities: Tampere, Helsinki and Espoo. The system is part of Lumikko’s extensive service concept, which offers comprehensive thermal management and ventilation solutions for rolling stock. With over 50 years of experience, Lumikko is a leading player in its field in Finland and internationally. Contact us and ask more about Lumikko’s regenerative braking system and our other services!
