equivalent Circuit Battery Models (Randles ECM) predict battery cell stress and overvoltage limits.
Longitudinal weight transfer alters dynamic wheel loads, making rear-axle regen highly prone to ABS wheel-lockup.
Pacejka's Magic Formula bounds tire adhesion grip based on the selected road friction (mu).
