News
Valeo präsentiert auf der BUS2BUS in Berlin sein neuestes Batteriekühlungssystem “E-Cooler”, das neue Hochvoltheizgerät "Thermo HV" für Elektrobusse und die SPump S120 und S200.
Valeo hat sich der Entwicklung von Lösungen für eine umweltfreundlichere Mobilität verschrieben und ist weltweit führend bei Technologien zur Verringerung der CO2-Emissionen und zur Verbesserung des Komforts an Bord von Omnibussen und Reisebussen.
Die schnell wachsende Elektrifizierung der Mobilität – insbesondere im öffentlichen Verkehr – erfordert leistungsstarke mobile Energiespeichersysteme, die den Reisekomfort erhöhen. In Berlin wird Valeo seine E-Cooler-Lösung vorstellen, die mit einer maximalen Kühlleistung von 10 kW eine Vielzahl von Anwendungen für das Batterietemperatur-Management ermöglicht. Je nach Anforderung schützt der E-Cooler die Batterie beim Laden und Entladen vor Überhitzung, kühlt sie während der Fahrt bei höheren Außentemperaturen und starker Beladung. Eine zusätzliche Heizfunktion wärmt die empfindlichen Batterien bei Bedarf sogar auf, um den optimalen Temperaturbereich wiederherzustellen.
Die von Valeo entwickelten Technologien sorgen für die richtigen Luftströme bei minimalem Energieverbrauch und Nutzung rückgewinnbarer Energie. Als Spezialist für Busklimatisierung und Pionier der E-Heizung stellt Valeo eine Hochspannungsheizung für Elektrobusse vor, die über ein integriertes Steuergerät die Heizleistung stufenlos regelt. Dies geschieht entweder durch die Steuerung der Wasseraustrittstemperatur oder durch die Begrenzung der maximalen Heizleistung bzw. des Stromverbrauchs. Mit dieser Funktion kann die Hochvoltheizung Thermo HV, die seit Juni 2023 in Serie produziert wird, auch aktiv in das Wärmemanagement des Fahrzeugs eingebunden und so die Gesamteffizienz des Systems erhöht werden. Mit einem Spannungsbereich von 450-850 VDC liefert die Thermo HV eine konstant hohe Heizleistung von 12kW. Das Modell mit 12kW/800V gilt als konkurrenzlos. Darüber hinaus ist sie CAN-fähig und überträgt über eine intelligente Diagnosefunktion wichtige Betriebsdaten an das Fahrzeugsystem.

From October 7 to 12, 2023, Valeo will be at Busworld Europe, the world’s largest event for buses and coaches taking place in Brussels, to showcase its innovative thermal management technologies for buses of all sizes and drive types.
Valeo is committed to developing solutions for greener mobility and a world leader in technologies to reduce CO2 emissions and improve comfort on board for buses and coaches. At Busworld Europe 2023, Valeo will focus on thermal management systems for buses worldwide – thermal comfort without compromise, maximum safety and fleet-efficient solutions with zero emissions.
The shift towards low-carbon mobility and subsequent fast growing market share of electrically powered buses has a significant impact on vehicle development and powertrain-related systems, including the heating and air conditioning systems.
The fast-growing electrification of mobility – particularly in public transport – requires high-performance mobile energy storage systems that enhance travel comfort. In Brussels, Valeo will showcase its E-Cooler solution, allowing a range of battery temperature management models with a maximum cooling capacity of 10 kW, an optimal solution for a wide range of applications. Depending on the requirement, the E-Cooler protects the battery from overheating during charging and discharging, cools it while driving at higher outside temperatures and heavy loads. An additional heating function even warms up the sensitive batteries if necessary to restore the optimum temperature range.
Moreover, with limited electrical energy available from traction batteries, innovative and efficient HVAC solutions for buses are needed. A strategic leader in this market, Valeo’s innovations provide a comfortable interior climate for passengers and efficient solutions for fleet owners whatever the weather conditions, the size of the vehicle, its powertrain type, the mode (urban, suburban or long-distance) and the duration of the journey.
The all-electric rooftop air conditioner REVO®-E HP R744, Valeo’s latest air conditioning system for buses with alternative engines will be presented at Busworld 2023. With a compact, reversible heat pump, this system cools and heats the interior of the electric vehicle efficiently and with low energy consumption. The unique dynamic de-icing on demand enables energy-saving heat pump operation even at cold outside temperatures lower than 5°C. The system is operated with the natural refrigerant R744. The chemical properties of this refrigerant and the specially developed control system enable it to be used at ambient temperatures from -20° to +50°C. The electronic control includes a holistic thermal management with its own developed software, which always operates the system at the optimal operating point. This means that the cooling/heating capacity is generated according to demand and available energy, so that the maximum coefficient of performance is always achieved.
The system impresses with a further significant reduction in noise emissions and weight, as well as a simplified refrigeration circuit. The integration of the compressor made it possible to achieve a compact system design, low refrigerant charge and low energy consumption. The refrigerant circuit is maintenance-free, durable components ensure low life cycle costs. The integrated battery cooling module keeps the battery at a constant temperature, which extends its service life and ensures greater efficiency. The new REVO®-E HP R744 has the same interface as Valeo’s REVO® classic system. For the vehicle manufacturer, this offers the greatest possible flexibility in installation and product mix. The system is a “plug & play” unit that can even be delivered to the customer pre-filled.
The technologies developed by Valeo ensure the right air flows while consuming a minimum of energy and using recoverable energy. Bus air-conditioning specialist and pioneer in e-heating, Valeo will be presenting a high-voltage heater for electric buses that steplessly regulates the heat output via an integrated control unit. This is done either by controlling the water outlet temperature or by limiting the maximum heating output or power consumption. With this function, the high-voltage heater Thermo HV, which has been in series production since June 2023, can also be actively integrated into the thermal management of the vehicle and the overall efficiency of the system can be increased. With a voltage range of 450-850 VDC, the Thermo HV provides a consistently high heat output of 12kW. Its 12kW/800V model is considered unrivaled. In addition, it is CAN-capable and transmits important operating data to the vehicle system via an intelligent diagnostic function.
