Program Simulates Performance of a Hybrid Automobile

The Hybrid Electric Vehicle Analysis (HEVA) computer program numerically simulates the performance of an automotive vehicle -- especially a hybrid vehicle. A vehicle is said to be hybrid if (1) it contains an energy-storage device (a battery, flywheel, or ultra-capacitor) that is charged with energy from a heat engine that burns natural gas or another fuel and (2) the energy-storage device is part of a system that provides electricity to a traction motor for propulsion.
