With intelligent and highly integrated thermal management components and systems Schaefflerincreases the range of electric vehicles up to 50 kilometers.
While the number of electric vehicles on the roads around the world is increasing day by day, the short range of these vehicles creates concern for drivers. One of the most basic ways to extend the range of electric vehicles is to reduce friction loss. Schaeffler, In order to prevent this loss, it significantly reduces friction with the high-efficiency transmission bearings it has developed, saving up to 50 watts of energy compared to conventional bearings. While this saving directly affects the range, it can also be used to heat the side mirrors or steering wheel in winter cold without reducing the vehicle range. SchaefflerIt also provides ideal load distribution with transmission bearings specially produced in accordance with the high rotation speeds of input shafts in electrically driven transmissions. Stating that they have developed solutions to address drivers’ concerns about range, Matthias Zink, CEO of Schaeffler Automotive Technologies, “Our wide range of components and systems for fully electric powertrains and smart technical solutions enable electric vehicles to be more efficient in daily use by reducing power consumption and extending their range. Thus, drivers do not need to charge their vehicles frequently. “Depending on the design of the vehicle, vehicle manufacturers can shrink the battery with the savings in power consumption, thus saving on the production costs of the vehicle.” said.

Schaeffler also establishes solution partnerships with manufacturers who want to extend the range even further with TriFinity wheel bearings. Wheel bearings, used as part of the chassis of electric vehicles, guide the drive shaft and axles and support the wheels so that they can rotate with minimum resistance even when exposed to high mechanical load. Wheel bearings are subjected to extraordinary forces during normal driving. Moreover, the bearings are in constant motion, rotating approximately 100 million times for every 180 thousand kilometers traveled. Schaeffler TriFinity wheel bearings reduce friction loss by a whopping 67 percent compared to ordinary wheel bearings. In other words, at full charge, an electric SUV with a 120-kWh battery capacity gains over 200 watts, corresponding to approximately 20 extra kilometers in range. This 200 watt saving allows it to be used to heat the driver and passenger seats without sacrificing range in winter.
Seat heating systems in electric vehicles consume approximately 100 watts per seat during the intense heating process. Producing a profitable and permanent method, TriFinity wheel bearings provide a weight saving of around 10 percent, although they are the same size as standard double-row ball bearings. It also offers long-lasting use. Moreover, it can carry more axle load with its higher strength rate of more than 20 percent. Thus, it provides a great advantage in heavier electric vehicles. Efficient thermal management plays a big role in increasing the range of electric vehicles. Schaeffler increases the efficiency of the range with the integrated thermal management system it developed by using CO₂ as a refrigerant in the heat pump. Noting that they have been providing thermal management solutions since 2011 Schaeffler E-Mobility President Dr. Jochen Schröder, “Especially in electric vehicles, thermal management has a decisive effect on features that customers care about, such as range and comfort. For this reason, it becomes one of the important points of competition among automotive manufacturers. “In this direction, we are developing a wide range of solutions, from integrated thermal management systems consisting of efficient and very useful components to 4-in-1 e-axles that combine the engine, transmission, power electronics and thermal management modules in a single optimized unit.” he states.
