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 system1for a battery-set of the invention includes a temperature detecting device15, a charging device12and a control device13for controlling the charging device12based on a battery temperature. The control device13carries 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.
