Abstract
Techniques are disclosed for systems and methods associated with a powertrain for a micro-mobility fleet vehicle. The fleet vehicle may include at least one drive wheel to provide tractive contact between the flee vehicle and a road surface, an electric motor mechanically coupled to the drive wheel and configured to provide motive force for the fleet vehicle, a brake resistor configured to provide dynamic braking of the motor, and a motor controller electronically coupling the brake resistor to the motor. The motor controller may be configured to control the motive force provided by the motor using the brake resistor. The motor controller may be configured to limit a speed, power, and/or acceleration of the motor using the brake resistor based on an operational environment of, and/or on a directive received by, the fleet vehicle. The brake resistor may provide a relatively wide range of traction control for the fleet vehicle.
