With the recent increase in the supply of compressed natural gas (CNG) for use as a motor fuel, the application of advanced hybrid technologies to improve fuel efficiency (thereby reducing operating costs and emissions) and extend the range of CNG fuelled vehicles provides an opportunity to accelerate the adoption of CNG as a motor fuel. With this increase in supply, however, has come a concomitant reduction in the cost of CNG that has changed the economics of hybridization from sophisticated full hybrids (at substantial cost) to simple start‒stop or launch-assist hybrids. This presentation details the start‒stop hybridization of a RAM 1500 pickup truck using CNG fuel and an advanced lead‒acid battery. The twin objectives of the RAM hybridization are to extend the vehicle range and to reduce its operating cost. Results prior to hybridization and post hybridization are presented for track, dynamometer and on-road testing, along with results of battery testing in accordance with the US Advanced Battery Consortium 12-Volt Start‒Stop Battery Test Manual.
