System and method for transferring energy between vehicles

A method, comprising the steps of:

• electrically connecting a first vehicle to a supply of electric power;
• electrically connecting the first vehicle to a second vehicle through an interface;
• while the first vehicle is connected to the supply of electric power, transferring electric power from the first vehicle to a battery of the second vehicle to recharge the battery while the first vehicle performs an operation that is different from a recharging operation;
• decoupling the first vehicle from the supply of electric power;
• and
• while the first vehicle is decoupled from the supply of electric power, transferring electric power from the second vehicle to the first vehicle to power at least one operation of the first vehicle;
• wherein the at least one operation includes a movement of the first vehicle from a first location to a second location;
• wherein the first vehicle includes a first traction motor;
• wherein the second vehicle is configured to supply electric power to the first traction motor of the first vehicle;
• wherein the first traction motor is configured to convert the electric power from the battery of the second vehicle into a mechanical output to effect the movement of the first vehicle.
