PROBLEM TO BE SOLVED: To suppress deterioration in performance of a secondary battery while suppressing unnecessary power consumption.SOLUTION: A charger 10 charges a lithium ion secondary battery 20A including: an electrode assembly comprising a positive electrode and a negative electrode; and an electrolyte including lithium ions. The lithium ion secondary battery 20A is attached with a vibration means 106 for applying vibration thereon. A vibration control means 108 operates the vibration means 106 in accordance with a charging operation of the lithium ion secondary battery 20A. The vibration intensity of the vibration means 106 is changed according to a charging current value and temperatures around the lithium ion secondary battery 20A.

    【課題】不要な電力消費を抑えつつ二次電池の性能低下を抑制すること。【解決手段】充電装置10は、正極および負極からなる電極体と、リチウムイオンを含む電解液とを有するリチウムイオン二次電池20Aを充電する。リチウムイオン二次電池20Aには、振動を加える加振手段106が取り付けられており、加振制御手段108は、リチウムイオン二次電池20Aの充電動作に対応して加振手段106を稼働させる。加振手段106の加振強度は、充電電流値やリチウムイオン二次電池20A周辺の温度によって変更される。【選択図】図1
