A Zinc-Chloride Battery - The Missing Link to a Practical Electric Car 730248

In order to prove the scale-up feasibility of a new battery system, a full-scale experimental package has been built and tested in a modified 1971 Vega Hatchback. Employing the zinc-chlorine couple, this unique system uses the solid, icelike compound chlorine hydrate to store chlorine safely and conveniently.The developmental hardware and some aspects of its design are described.A discussion of the complete electric propulsion system is presented. Details of the system auxiliaries, electrical controls, and vehicle instrumentation are also included.It is concluded that the zinc-chloride battery is a viable solution to the principal problem impeding the development of electric cars-a high power, high energy density battery.
