ROLLING RESISTANCE & HYSTERESIS COSTS YOU THOUSANDS (PART I)

EV Channels Review

In this installment, John Cadogan delves into the physics of hysteresis and rolling resistance, explaining how these phenomena lead to significant energy loss in vehicles. He uses the analogy of a bouncing ball to illustrate how energy is dissipated as heat during impact and rebound, a process that directly translates to the rolling tire. Cadogan highlights that approximately 25% of all fuel burned is used to overcome rolling resistance. He emphasizes that this energy loss impacts all vehicles, including EVs, reducing their range by about 25%. The video sets the stage for a deeper dive into the pervasiveness of hysteresis in automotive systems, promising to explore its effects on cruise control and air conditioning accuracy in the next part.
