To provide a charging device and a charging method capable of completing charging of a plurality of storage batteries efficiently and in a short time and maintaining a good state of the storage batteries.SOLUTION: In a charging device and a charging method, when there is a DC/DC converter that does not supply a current and the total amount of current supplied from the DC/DC converter is less than or equal to a current threshold, a process of switching the connection between a DC/DC converter that does not supply a current and a connector connected to a storage battery that starts charging and starting the supply of a charging current is repeated, and the current amount of the charging current is a current amount obtained by subtracting the predetermined current amount from the maximum current amount that can be supplied from the power converter, and the predetermined amount of current is equal to or greater than the current threshold value.SELECTED DRAWING: Figure 1 【課題】効率的かつ短時間で複数の蓄電池の充電を完了でき、かつ、蓄電池の良好な状態を維持することができる充電装置および充電方法を提供する。【解決手段】上記課題は、電流の供給を行っていないＤＣ／ＤＣ変換器があり、かつ、ＤＣ／ＤＣ変換器から供給している電流の総量が電流閾値以下である場合には、電流の供給を行っていないＤＣ／ＤＣ変換器と、充電を開始する蓄電池に接続されたコネクタとの接続を切り替えて、充電電流の供給を開始するプロセスを繰り返し、該充電電流の電流量は電力変換器から供給可能な最大電流量から所定の電流量を減じた電流量であり、該所定の電流量は電流閾値以上である充電方法および装置により、解決することができる。【選択図】図１
