To provide a battery charger that suppresses the deterioration of connector terminals due to water wetting by leaving the connector outdoors and immersion in rainwater itself or chemical substances contained in rainwater, and the occurrence of defects caused by the deterioration of connector terminals.SOLUTION: A battery charger includes a charging unit that charges a power storage battery mounted on an electric vehicle via a plurality of terminals of a charge/discharge connector 12 and a charge/discharge cable 11, a latch 106 having a convex portion 106b that protrudes from the charge/discharge connector 12 when the electric vehicle and the charge/discharge connector 12 are connected to maintain a connection state between the electric vehicle and the charge/discharge connector 12, and a connector fitting detection unit that detects whether the charge/discharge connector 12 is fitted to a holder 50c on the basis of the rotation state of the latch 106, and when it is detected that the charge/discharge connector 12 is not fitted to the holder 50c, the charging unit stops energizing the plurality of terminals of the charge/discharge connector 12.SELECTED DRAWING: Figure 8
【課題】コネクタの屋外放置による水濡れ、及び雨水自体又は雨水に含まれる化学物質への浸漬によるコネクタ端子の劣化及びコネクタ端子の劣化に伴う不具合の発生を抑えた充電器を得ること。【解決手段】充放電コネクタ12の複数の端子及び充放電ケーブル11を介して、電動車両に搭載される蓄電池への充電を行う充電部と、電動車両と充放電コネクタ12との接続時に充放電コネクタ12から突出して電動車両と充放電コネクタ12との接続状態を維持する凸部106bを備えたラッチ106と、ラッチ106の回動状態に基づいて充放電コネクタ12がホルダ50cと嵌合しているか否かを検出するコネクタ嵌合検出部とを備え、充電部は、充放電コネクタ12がホルダ50cと嵌合していないことが検出された場合に、充放電コネクタ12の複数の端子への通電を停止する。【選択図】図8
