Tests of a full-sized mechanically rechargeable zinc-air battery in an electric vehicle

A mechanically rechargeable zinc-air battery that has high power density and fast refueling capability is described. The battery is built from modules of 32 or 44 cells connected in series, and the modules can be arranged in any combination of series and parallel connections, and in practical quantity, according to the requirements of the vehicle, motor, and controller. The results of laboratory and in-vehicle tests of a zinc-air battery consisting of two 32-cell modules connected in series, with nominal voltage of 75 V and nominal capacity of 216 Ah, are presented.<
