Rapid Charging Batteries for Electric Propulsion Systems

Requirements and constraints for rapid charging batteries used for both pulse load and deep cycle service are outlined. Methods for fast recharging nickel-cadmium and lead acid batteries are described. A new rapid charge concept wherein nickel-cadmium batteries are both rapid charged and reconditioned is presented. Similarly, a unique method of fast charging lead acid batteries is described and illustrated. Areas of required technology improvements in batteries and electronic control devices for rapid charge application are outlined.
