EV Technical Guide

EV Suspension & Alignment

Inspecting chassis suspension components subjected to heavy pack mass (>2000 kg) and instant torque.

Chassis Suspensions & Battery Mass Impact

Heavy battery pack mass (400 kg to 700 kg) accelerates wear on ball joints, control arm bushings, and air suspension struts on rough roads.

Inspection Checkpoints:

  • Control Arm Bushing Checks: Inspecting rubber bushings for tearing caused by instant motor torque transfer.
  • Air Suspension Level Calibration: Calibrating ride height sensors to maintain optimal aerodynamic efficiency and range.
  • Four-Wheel Alignment: Laser alignment to prevent uneven inner tire tread wear caused by heavy battery mass.
