The supplier Schaeffler plans to present a range of eMobility solutions at the IAA Mobility. Schaeffler has now announced 800-volt power electronics for e-axle systems and a highly integrated thermal management system as a new product.
The 800-volt power electronics are intended for applications in e-axles of “high-performance vehicles”. Specifically, the supplier states in the announcement that the scalable solution should enable continuous power outputs of up to 330 kW and short-term peak power outputs of up to 500 kW. Schaeffler states that the power density is 70 kW per litre, which should result in a small housing and thus advantages in integration. For efficiency reasons, Schaeffler relies on silicon carbide and aims to achieve efficiencies of up to 99 percent “in defined load ranges”.
Schaeffler shows how power electronics can be used in its “3in1 e-axle”. This combines electric motor, transmission and power electronics in one system. “The performance E-axle from Schaeffler impresses with an outstanding torque density of the transmission and is characterised above all by compactness, high power density, high system efficiency and excellent acoustic behaviour,” the supplier writes in this regard – but does not give any technical data in advance.
“Our decades of expertise in the field of internal combustion engine drives is the basis for shaping change that moves the world in e-mobility as well,” says Matthias Zink, Member of the Executive Board for Automotive Technologies at Schaeffler AG.” Numerous series nominations in the field of electrified drives prove that Schaeffler is on the right track.”
The supplier states that in the E-Mobility division, the order intake volume in the first half of 2021 is €2.1 billion, “which means that the target issued for 2021 as a whole has already been achieved.” Jochen Schröder, head of the E-Mobility division, added: “From 2022 onwards, an annual order intake of 2-3 billion euros is planned in the E-Mobility division.”
In addition to the drive solutions, Schaeffler is also showing a new thermal management system that combines all important functions in a central control unit. Schaeffler claims that the required installation space is reduced by up to 60 per cent. Competitor Brose has also announced a highly integrated thermal control for the IAA Mobility.
Schaeffler has its stand in Munich in Hall B3, Stand A80.
