Arizona Public Service (APS) has joined Southern California Edison (SCE) in sponsoring construction of a high performance Electric Vehicle based on a Honda CRX using DEMI's proprietary rechargeable Zinc-Air battery technology. The Zinc-Air CRX went 215 miles (346 km) on a single charge in its first test at an average speed of 45 mph (72 km/h) (SAE “D” cycle) and demonstrated a top speed of 87 mph (140 km/h). At the Inaugural Solar and Electric (S&E) 500 at the Phoenix International Raceway April 5-7, 1991, the CRX set a national record for a 1-mile closed course at 69.44 mph (112 km/h). The car won the pole position and dominated the 2 hour race winning by a comfortable 4-lap margin against a field of 12 other EVs from all over the United States. This paper covers the results of vehicle testing to date and the car's battery and electrical subsystems.

Dreisbach ElectroMotive, Inc. (DEMI) is developing and testing a maintenance-free wall-plug rechargeable Zinc-Air Battery to power Electric Vehicles. This new battery technology offers over 200 mile vehicle range capability from very low cost, commonly available raw materials. This paper will focus on the preliminary systems integration needed by an electric Vehicle to operate these air breathing batteries in various common environments. Air cooling and reaction air requirements will be covered as well as the actual systems used to implement these requirements in a Chrysler minivan* which is sponsored by Southern California Edison (SCE). In addition, the projected system implementations of Zinc-Air batteries in automobiles and multi-use vans will be presented.
