Modular system for dynamic tow and regenerative braking of a trailer

A kit comprising:

• a driven axle configured to install on a bogie chassis supporting a trailer chassis of a trailer;
• a motor coupled to the driven axle;
• a battery assembly:
• comprising a set of retention features configured to transiently engage a set of engagement features on the trailer chassis to couple the battery assembly to the trailer chassis;
• configured to supply electrical energy to the motor to drive the driven axle;
• and
• configured to receive electrical energy from the motor to regeneratively brake the driven axle;
• an electrical cable configured to electrically couple the motor and the battery assembly;
• a cable carrier configured to:
• locate between the bogie chassis and the battery assembly;
• house the electrical cable;
• and
• support the electrical cable over a range of longitudinal positions of the bogie chassis relative to the battery assembly;
• and
• a cooling module comprising:
• a first radiator configured to fluidly couple to the battery assembly via a first coolant loop;
• and
• a second radiator configured to fluidly couple to the motor via a second coolant loop.
