英文摘要：

The charge control strategy was investigated according to the characteristics of zinc-silver battery. Pre-discharging avoids the unexpectedly raising of the cell voltage when the battery is charging. Series resistances decrease current fluctuations and battery depletion. The charging of zinc-silver depends on the double-loop control of voltage and current. The design of the smart charger control circuit and main circuit was described, and the software design was introduced. A new type large capacity charger of aviation zinc-silver battery was developed based on the control strategy, and successfully applied in a aviation ground support equipment. The overall design concept of the smart charger was described. The developed chargers show the control strategy is feasible and reasonable.
