Expanded functionality stop-start fuel saving system for vocational vehicles

An engine stop-start fuel saving system for a vocational vehicle propelled by a conventional internal combustion engine and powertrain, the system comprising:

• a) a low storage capacity, rapid recharge, high cycle life electric energy storage device;
• b) a motor that is powered by the energy storage device and that is coupled to the engine and;
• c) a generator that is coupled to the engine and that is connected to recharge the electric energy storage device;
• d) a controller that is responsive to one or more operating conditions to activate the motor that is coupled to the engine so as to restart the engine when it is stopped, and to engage the generator to recharge the electric energy storage device, and to subsequently stop the engine again when the electric energy storage device has reached a threshold level of charge;
• e) wherein the electric energy storage device also powers at least one of:
• i) integral equipment of the vehicle;
• ii) peripheral equipment included on the vehicle;
• iii) an electrical outlet circuit with a socket for external plug-in electrical equipment;
• and
• wherein the electric energy storage device is an ultracapacitor.
