Abstract

One variation of a system includes a bogie including: a chassis; a first set of latches configured to transiently engage a first subset of engagement features, in a first array of engagement features on a left rail and in a second array of engagement features on a right rail of the trailer, to retain the bogie below a floor of the trailer; a driven axle suspended from the chassis; and a motor coupled to the driven axle and configured to output torque to the driven axle and regeneratively brake the driven axle. The system further includes a battery assembly: including a second set of latches configured to transiently engage a second subset of engagement features, in the first array of engagement features and in the second array of engagement features, to retain the battery assembly adjacent the bogie; and configured to receive electrical energy from the motor.
