Abstract
An object is to provide a charging system in which a battery can be charged in a fully charged state or close to the fully charged state while preventing performance deterioration of a battery due to heat generated during charge. A charging systemfor a battery-set of the invention includes a temperature detecting device, a charging deviceand a control devicefor controlling the charging devicebased on a battery temperature. The control devicecarries out a temperature feedback charge with 'a quantity function of a temperature' (ΔT/Δt) as a target value (Y). With the system, it is possible to charge the battery in the fully charged state or close to the fully charged state while preventing the performance deterioration of the battery due to the heat generated during the charge.
