Modular system for dynamic tow and regenerative braking of a trailer

A kit comprising:

• a driven axle configured to install on a trailer;
• a motor coupled to the driven axle;
• and
• a battery assembly:
• configured to install on the trailer;
• and
• comprising:
• a set of cross members;
• a set of batteries arranged between the set of cross members;
• a set of clamps, each clamp in the set of clamps:
• coupled to a cross member in the set of cross members;
• and
• configured to couple the battery assembly to a pair of adjacent beams of the trailer to suspend the battery assembly below the trailer;
• and
• a set of fasteners, each fastener in the set of fasteners configured to:
• extend through a cross member in the set of cross members;
• and
• couple a clamp, in the set of clamps, to the cross member.

A battery assembly comprising:

• a set of cross members;
• a set of batteries:
• arranged between the set of cross members;
• and
• configured to:
• supply electrical energy to a motor of a trailer to drive a driven axle of the trailer;
• and
• receive electrical energy from the motor during regenerative braking of the driven axle by the motor;
• a clamp:
• coupled to a cross member in the set of cross members;
• and
• configured to couple the battery assembly to a pair of adjacent beams of the trailer to suspend the battery assembly below the trailer;
• and
• a fastener configured to:
• extend through the cross member and into a nut of the clamp;
• and
• rotate the nut and the clamp in a plane orthogonal to a longitudinal axis of the fastener to couple the clamp to a pair of adjacent beams of the trailer.
