Charged EVs | Schaeffler showcases new compact EV vary extender with built-in motor and energy electronics

Schaeffler showcased a compact, extremely built-in generator module for vary extender electrical autos (REEVs), new high-performance grasp management models designed for software-defined autos, and ongoing work on thermal administration options utilizing PFAS-free refrigerants on the CTI Symposium in Berlin.

The brand new vary extender module targets REEVs—autos gaining momentum in China and the US for functions that require prolonged driving vary. Schaeffler says that the module combines an electrical motor and energy electronics, an built-in cooling system with oil pump, water connection and oil filter inside a compact type issue. The Energy Class 2 model delivers as much as 300 kW of steady charging energy, instantly offering power to the battery and enough for towing pickup vans with trailers. The vary extender is available in 400 V and 800 V variants and operates when battery ranges drop under an outlined threshold. The smaller 80 kW module achieves an axial size below 200 mm, facilitating set up alongside an inner combustion engine and generator inside EV powertrains.

Schaeffler’s new Excessive Efficiency Grasp Management Unit (HP MCU) for software-defined autos. The HP MCU, constructed on the Aurix T4x micro-controller household and optionally the S32 system-on-chip, follows a modular and scalable platform strategy. Schaeffler says this unit as a central integration platform for all powertrain capabilities, supposed to enhance real-time management and allow extra environment friendly orchestration of EV parts.

Schaeffler additionally confirmed its VoltShield-P insulation bearing for electrical motors. This answer is designed to forestall bearing harm from high-frequency circulating currents. The corporate additionally highlights ongoing growth of thermal administration programs suitable with PFAS-free refrigerants, together with propane and carbon dioxide, to handle evolving environmental laws and operational necessities.

Schaeffler notes its product lineup is modular throughout mechanical, digital and mechatronic parts, and encompasses options for battery-electric autos, all hybrid configurations and REEV architectures.

“Due to its product vary and progressive power, Schaeffler is carving out a defining function within the e-mobility section, as a result of we actually do cowl the whole lot, from mechanical parts, modules and full programs to options for contemporary automobile electrical architectures with centralized software program for the software-defined automobile,” stated Thomas Stierle, CEO E-Mobility at Schaeffler.
