Abstract

Telematic method and apparatus adaptively uses fuel cell power source in vehicle with integrated power system, electrical system, telematic system, and body/powertrain system. Telematic communications systems including internet, digital video broadcast entertainment, digital audio broadcast, digital multimedia broadcast, global positioning system navigation, safety services, intelligent transportation systems, and/or universal mobile telecommunications system. Network-accessible software enables integrated modular function for automated control and provision of fuel cell resources for telematic appliance and/or other vehicle electro-mechanical devices.

Claims

1. Integrated power and telematic system comprising:

a central controller coupled via a gateway to an electrical system; and

a telematic system coupled to a 36-volt load coupled to a 42-volt DC bus.

2. System of claim 1 wherein a body/powertrain control system is coupled to a 14-volt load coupled to a 14-volt DC bus, and also coupled to the 42-volt DC bus via a DC-DC converter.

3. Integrated power and telematic activation method comprising steps:

activating a gateway microprocessor to run software for vehicle systems;

activating an electrical system including a 36-volt load for a telematic system, and a 14-volt load for a body/powertrain system;

activating a power-system power control unit; and

activating a fuel cell stack process.

4. Method of claim 3 wherein the power control unit couples the fuel cell stack via an inverter to a traction motor.
