Tula Technology has updated its Dynamic Motor Drive (DMD) software to improve efficiency in electric vehicles (EVs) at low loads.
DMD eliminates reliance on rare earth elements and provides more efficiency at a lower cost.
By applying DMD to the rear axle of an EV equipped with internal permanent magnet motors, vehicle range increased by 0.6%, and applying DMD to both axles could increase range by 1.5%.
Tula has received interest from automakers to implement DMD on their platforms for battery-electric vehicles and plug-in hybrids.
