Air metal battery charging device, air metal battery assembly and air metal battery charging system including the same

摘要

The present invention relates to a metal-air cell charging apparatus, to a metal-air cell assembly, and to a metal-air cell charging system comprising same. The present invention provides a metal-air cell charging apparatus for charging a metal-air cell assembly including a secondary metal-air cell having a negative electrode gel, and a case for accommodating the secondary metal-air cell therein, wherein the metal-air cell charging apparatus comprises: a charging unit which generates, using an external power source, power to be supplied to the metal-air cell assembly, and supplies the thus-generated power to the metal-air cell assembly; and a humidifying air supply unit which generates humidifying air containing a predetermined amount of moisture, and supplies the humidifying air to the interior of the case via a humidifying air supply port connected to the metal-air cell assembly.
