The Valeo innovations at the epicenter of the revolutions shaping passenger transportation

A major change echoes the one currently transforming the passenger transportation industry – the powertrain revolution. In the interests of both the climate and public health, now and in the future, powertrains must reduce or eliminate their CO₂ emissions. Around the world, cities are taking action to restrict road access exclusively to clean vehicles, limiting emissions of greenhouse gases and fine particles (see Did You Know? on pages 5 and 6). The world’s major cities, and even some smaller ones, have become the new regulators, stipulating which vehicles can and cannot use their roads.

The solution being adopted for buses and coaches is powertrain electrification, a change that has a significant impact right from the vehicle design phase. How, for example, can vehicle manufacturers continue to ensure passenger comfort when there is no longer an internal combustion engine to help regulate temperature? The increasing popularity of more environmentally friendly vehicles raises the critical question of how much energy is needed to produce heat or cool air in the cabin. Batteries, which are highly sensitive to changes in temperature, also pose a challenge because they need to be constantly maintained within the optimal operating range.

Valeo is the world leader in CO2 emissions reduction and also in air conditioning systems for buses and coaches. Valeo’s innovations provide practical, efficient solutions, regardless of the weather, the size of the vehicle, its powertrain type, and the nature (whether urban, peri-urban or long-haul) and duration of its journey. The technologies developed by Valeo generate the right air flows, while using the minimum amount of energy necessary and reusing recoverable energy. These actions are driven by electronics and software programs that are also developed by Valeo.

Valeo is also innovating in the area of battery cooling, with new systems that extend vehicle range and improve the preservation of battery service life. All these innovations work together to reduce the total cost of operating buses and coaches.

Among the innovative technologies presented by Valeo at the 25th Busworld exhibition, the Group is unveiling the new Valeo REVO-E HP R744, an all-electric rooftop a/c unit that uses a natural refrigerant and generates zero emissions.
