The Hidden Impact of Auxiliary Systems on EV Efficiency and Range
Electric vehicle (EV) engineers often invest millions to improve the main powertrain’s efficiency by fractions of a percent. Traction motors and inverters in modern EVs can already exceed 95% efficiency[1], so squeezing out an extra 0.1% is a costly challenge. Yet too often this hard-won gain is negated by overlooked auxiliary systems – the small motors and devices that support cooling, heating, steering, and other functions.
