To provide a quick charging device and a quick charging method having excellent efficiency when quickly charging a solid-state battery.SOLUTION: A quick charging device has: a charging unit for supplying electric current to a solid-state battery as a secondary battery; a temperature acquisition unit for acquiring a temperature of the solid-state battery; and a control unit for performing control to cool the solid-state battery when a temperature acquired by the temperature acquisition unit is equal to or higher than a predetermined temperature. The control unit detects multiple flexion points in a curve that shows temperature variation of the solid-state battery with respect to internal resistance of the solid-state battery. The predetermined temperature is a temperature in correspondence with a flexion point on a high temperature side among the multiple flexion points.SELECTED DRAWING: Figure 3

    【課題】固体電池を急速充電する際の効率に優れる急速充電装置及び急速充電方法を提供すること。【解決手段】二次電池としての固体電池に電流を供給する充電部と、固体電池の温度を取得する温度取得部と、温度取得部により取得された温度が所定温度以上である場合、固体電池を冷却する制御を行う制御部と、を有する急速充電装置。制御部は、固体電池の内部抵抗に対する固体電池の温度変化を示す曲線において、複数の変曲点を検出し、所定温度は、複数の変曲点のうち、高温側の変曲点に対応する温度である。【選択図】図3
