Transportation experts are predicting that as many as one-third of all commercial trucks and buses will have alternative drivetrains by 2030. Many of these are expected to be fully electric. With this push to vehicle electrification, vehicle designers will need to rethink how to power accessories.
Today’s vehicles with internal combustion engines rely on belt-driven accessories for power steering assistance, air conditioning and battery charging. With electric drivetrains, fans and alternators are eliminated, as are belt-driven accessories. Instead, air conditioning compressors and power steering pumps will need to be driven by small electric motors.
