Method and system for managing energy on board a vehicle

A computer data processing system comprising:

• a computer with memory and a processor disposed on board a vehicle;
• and,
• a management module comprising program code enabled during execution of the code in the computer to determine a level of electrical power produced, stored, or produced and stored by an electrical current generating module of a first electrical network on board the vehicle, to supply electrical power by means of the first electrical network to a second electrical network on board the vehicle that is galvanically isolated from the first electrical network, and and to supply electrical power to electrical equipment of the vehicle by means of the second electrical network.

A vehicle power management system for managing power on board a vehicle, said system comprising:

• a first electrical network, a second electrical network electrically isolated from the first electrical network and at least one piece of electrical equipment connected to the second electrical network, said first electrical network comprising at least one module for generating electrical current that is configured to produce and/or store electrical power, said second electrical network comprising at least one electrochemical generator unit and at least one module for storing electrical power;
• a computer with memory and at least one processor in which a management module executes, the management module comprising program code enabled during execution of the code in the computer to determine a level of electrical power produced, stored, or produced and stored by an electrical current generating module of a first electrical network on board the vehicle, to supply electrical power by means of the first electrical network to the second electrical network and to supply electrical power to the electrical equipment of the vehicle by means of the second electrical network.
