Dual mode range extended electric vehicle

A system integrated into a vehicle, the system comprising:

• a motor, said motor providing propulsion power to said vehicle;
• a battery coupled to said motor and providing energy to said motor;
• a generator system, said generator system comprising an engine, said engine burning fuel selected from the group consisting of fossil fuels, synthetic fuels and bio-fuels, wherein said generator system provides charging energy for said battery;
• an engine control circuit to power on and power off said engine, wherein said engine control circuit powers on said engine when it receives an engine control signal;
• a state of charge circuit configured to monitor a battery state of charge and preprogrammed to provide said engine control signal in accordance with an operational mode, wherein said operational mode is selected from at least a first operational mode and a second operational mode, and wherein
• the state of charge circuit in said first operational mode provides said engine control signal when said battery state of charge falls below a first state of charge and until said battery state of charge reaches a second state of charge, wherein said second state of charge is higher than said first state of charge, and
• the state of charge circuit in said second operational mode provides said engine control signal when said battery state of charge falls below a third state of charge and until said battery state of charge reaches a fourth state of charge, wherein said fourth state of charge is higher than the third state of charge, and wherein both said third state of charge and said fourth state of charge are lower than both said first state of charge and said second state of charge;
• and
• a user interface coupled to said state of charge circuit and configured to receive a user command selecting said operational mode for the state of charge circuit, wherein said operational mode is selected from at least said first operational mode and said second operational mode.
