Abstract

A control device for controlling charging of a non-aqueous metal air battery, the control device being configured to: determine a COconcentration (C) and an increase rate (RCO) of COconcentration in the battery, charge the battery in case both the COconcentration (C) before starting charging exceeds a predetermined COthreshold (C) and the increase rate of the COconcentration (RCO) during charging is below a predetermined threshold value (ΔC/ΔAh, ΔC/Δt), and stop charging when the increase rate (RCO) exceeds the predetermined threshold value (ΔC/ΔAh, ΔC/Δt). Also, a corresponding method of controlling charging of a rechargeable battery.
