Abstract

A control device for controlling charging of a non-aqueous metal air battery, the control device being configured to: determine a CO2 concentration (Cx) and an increase rate (RCO2) of CO2 concentration in the battery, charge the battery in case both the CO2 concentration (Cx) before starting charging exceeds a predetermined CO2 threshold (CT) and the increase rate of the CO2 concentration (RCO2) during charging is below a predetermined threshold value (ΔCT/ΔAhT, ΔCT/Δt), and stop charging when the increase rate (RCO2) exceeds the predetermined threshold value (ΔCT/ΔAhT, ΔCT/Δt). Also, a corresponding method of controlling charging of a rechargeable battery.
