Design & Engineering Insights: New Allison Transmission Electric Axles Bring Efficiency Benefits

Alexander Schey, Chief Commercial Officer, Electrification at Allison Transmission, says one of the key points of electrification is efficiency which can be optimized by developing drivetrain components specifically for electric vehicles. He says doing so can improve efficiency because you can do things differently than you might with conventional vehicles such as electrically powering braking or other auxiliary systems. Allison Transmission recently introduced its eGen Power 100D Electric Axles for electric vehicles. It features two electric motors used in parallel to spin the wheels. Their unique layout ensures more efficient transfer of energy, which helps with overall vehicle efficiency. In addition, compact packaging of the electric axles reduces the amount of space they require on the vehicle which can further benefit efficiency.
