An engine stop-start fuel saving system for a vocational vehicle propelled by a conventional internal combustion engine and powertrain. The system uses a low storage capacity, rapid recharge, high cycle life electric energy storage device, such as an ultracapacitor. The system also includes a generator that is coupled to the engine and that is connected to recharge the electric energy storage device, as well as a motor that is powered by the energy storage device and that is coupled to the engine. The system also includes a controller that can activate the motor to restart the engine when it is stopped, and engage the generator to recharge the electric energy storage device, and that can subsequently stop the engine again when the electric energy storage device has reached a threshold charge level. The electric energy storage device also powers at least one of: integral vehicle equipment; peripheral vehicle equipment; or an electrical outlet circuit with a socket for external plugin equipment.
