Intelligent Climate Network for Electric Buses: Digitization Meets Efficiency
The future of public transport is electric, but with the electrification of bus fleets, thermal management is becoming increasingly important. Climate control systems belong to the largest energy consumers in electric buses and significantly influence range, battery lifespan, and operating costs. Inefficient heating or cooling can have the consequences that vehicles do not reach their scheduled operating times or the battery is additionally stressed.
With the CO₂ Heat Pump NeXwork, Konvekta presents an innovative solution that reaches a new level of energy efficiency through digital networking. The system combines a CO₂ heat pump with new patented components such as a fill level control, an internal heat exchanger, and other key technologies like battery temperature control, Energy Collect (heat recovery), sensor technology, and intelligent control equipped with new software –All this in a fully networked overall package.Unlike conventional heating and cooling systems that typically operate as standalone components, NeXwork continuously analyzes all relevant parameters such as outside temperature, passenger numbers, and battery status. Based on this data, the air conditioning adjusts in real time, preventing unnecessary energy consumption.While conventional systems often rely on additional electric heaters, the CO₂ Heat Pump NeXwork minimizes electricity consumption by utilizing heat energy from ambient air and components like axles, inverters, and batteries. Precise control of the thermal system and its components ensures that generated heat is used efficiently and optimally distributed.
Maximum Energy Savings Through Smart Control
A key element of the intelligent control is LeadControl, a platform-based remote maintenance and diagnostics unit. It not only enables predictive maintenance but also dynamic optimization of the climate network. This leads to further reductions in energy consumption and ensures long-term stable climate conditions.
The AES mode (Additional Energy Storage) is also applied. This innovative software module makes an additional electric heater unnecessary by distributing the available heat 100% need based This means that all available heat can be used for hot water preparation, which leads to significant energy savings, especially during the cold season.
Also in the field of maintenance and servicing, the CO₂ Heat Pump NeXwork offers significant advantages. Thanks to digital networking, the system enables remote maintenance and real-time fault diagnostics. Software updates and optimizations can be carried out remotely, reducing maintenance costs and increasing reliability in daily operation.
Sustainability and Environmental Friendliness
Another advantage of the NeXwork system is its environmentally friendly climate control. As additional electric heaters are no longer needed, energy consumption is significantly reduced while simultaneously the environmental balance of the vehicles is being increased.
The system uses only CO₂ (R744) as refrigerant – a natural substance with a Global Warming Potential (GWP) of 1. Unlike synthetic refrigerants, CO₂ leaves no PFAS or environmentally harmful decomposition products. Moreover, CO₂ is not subject to legal restrictions, making it a long-term safe and sustainable solution for public transport.
With CO₂ Heat Pump NeXwork, Konvekta is setting new standards in CO₂ thermal management for electric buses. The combination of intelligent control, efficient heat utilization, and environmentally friendly technology creates a pioneering solution for the future of public transport.
