See how an electric braking resistor replaces combustion-based fire tubes to eliminate harmful

A controller arbitrates fuel cell and regenerative braking power to prevent HV battery over-voltage and avoid traction loss.

Electric braking holds a vehicle during brake release, then tapers torque to prevent sudden downhill acceleration and improve drivability.

Baseline service brake torque fills gaps in regenerative braking, while the electrical machine controls wheel slip for faster heavy-duty braking response.

Route and vehicle-weight prediction expands battery SOC limits when regenerative braking is constrained, improving energy use without sacrificing battery health.

Switching brake chopper conditions suppress reverse power flow and inverter DC overvoltage during regenerative braking on or off the overhead line.

Temperature sensors in the resistor cooling path gate brake chopper activation to prevent overheating during long downhill braking.

A bidirectional throttle with a torsional spring gives riders tactile control of regenerative braking, improving stability and drive feel.

A modular power interface lets work vehicles swap power sources while reclaiming braking energy to storage instead of wasting it in retarding grids.

Controller logic adjusts air compressor speed to match battery charge acceptance during regenerative braking, preventing bus overvoltage.

Gradient compensation and position-based control help maglev eddy current braking stop closer to the designated parking position.
