Automotive provider Magna this week unveiled a brand new piece of {hardware} for decoupling EV drive motors that the corporate claims can enhance vary by as much as 9%.
Disconnecting drive motors when their energy will not be wanted reduces vitality consumption and drag-torque losses from the motor and its gearbox, Magna mentioned in a press launch. That helps enhance total effectivity.
Magna eDecoupling unit
Magna claims its electromechanical eDecoupling machine could be simply added to present EV powertrain designs, interfacing with a car’s powertrain controls and activating in lower than 100 milliseconds. The corporate says the unit is appropriate for hybrids in addition to EVs, in autos together with SUVs and light-weight industrial autos.
Manufacturing of the eDecoupling unit will happen at Magna’s facility in Lannach, Austria. The unit will launch on “a number of autos of a German premium automaker,” in line with the corporate.
Magna additionally serves as contract producer for the Fisker Ocean, nevertheless it’s unclear whether or not this is identical “distinctive clutch” that Fisker CEO Henrik Fisker has mentioned is being utilized in that EV. Magna has beforehand claimed, with an illustration Jaguar I-Tempo (one other car Magna builds underneath contract), that it may enhance EV vary as much as 30% principally with modifications to software program and controls.

Addressing drag from inactive electrical motors may unlock higher EV effectivity.
Everlasting-magnet motors proceed to exert drag on the driveline and might’t actually coast, in order that they’re finest engaged in regenerative braking. Lots of the latest-generation electrical motors—comparable to those Common Motors is utilizing in its Ultium fashions—have been designed particularly for very low-load situations that might apply to cruising and coasting. Polestar has additionally mentioned that its next-generation motors will be capable to disconnect.
