An air conditioning system for an electric transport vehicle supplied by an electrical supply network includes at least one actuator for the production of heat or cold, and a regulator configured in order to generate at least one operating command applied to the at least one actuator as a function of values for parameters representing the climatic conditions, the actuator delivering an average power over a predetermined time period. The regulator are configured in order to generate at least one operating command applied to at least one actuator as a function moreover of the value for a parameter relating to at least one electric transport vehicle supplied by the electrical supply network, the value for the parameter indicating that electrical energy is consumed by the at least one electric transport vehicle or that electrical energy is produced by the at least one electric vehicle.

A service vehicle can have a service vehicle battery that can provide energy to, and/or receive energy from, a separate machine that is normally configured to operate based on energy provided by a battery of the machine. If a machine becomes unable to operate using the battery of the machine, the service vehicle can travel to the machine and use an energy transfer arm to transfer energy to the machine. In some situations, the service vehicle and the machine can travel together in a convoy formation, for instance to a maintenance station, while the service vehicle provides the machine with energy for driving operations of the machine.
