Multi-speed gearboxes can offer many benefits for EV powertrains depending on application

admin    Drive Subsystems Energy Efficiency Feature Powertrain
by S.E.Tice… Electric motors have full torque at 0 rpm and a much wider operating RPM range than ICEs (internal combustion engines).  Despite this feature, the efficiency of electric motors still varies at different speeds – they operate at a peak efficiency of around 90-95% but this can fall to...

End to End Energy Cycle Efficiency – Do All-Electric Vehicles (BEVs) really Win?

admin    Energy Efficiency Feature
by S.E.Tice… “The conclusion is that All-Electric Vehicles (BEVs) beat the fleet average ICE vehicle hands down in every group of states they evaluated, on a full lifecycle emissions basis, and in fact they outperform the Prius (52 mpg (4.5 L/100km)) in most states. In the most populous states, BEVs...
