A power supply system is installed in a vehicle having one or more sources of electrical energy. The power supply system includes at least two distributing boxes each having at least one internal distribution bus, at least two output switches and a driver processor. The internal distribution bus can be connected to the source or sources of electrical energy. The output switches for each supplies a different electrical consumer of the vehicle from the internal distribution bus. The driver processor controls the output switches so as to distribute a consumption load between the electrical consumers in association with different operating modes of the vehicle.

An energy offloading system is in direct electric communication with an energy generating system and dynamically receives energy from the energy generating system. The energy offloading system uses energy for high-load computations. The energy offloading system includes computers performing the high-load computations as well as servers, cooling units, and communication devices. When the energy from the energy generating system is terminated, the energy offloading system may power down these and other devices, or may switch these devices to an alternative power source. The energy offloading system may be portable.
