Abstract: Charger for an industrial truck which has an asynchronous machine and a three-phase AC control unit for converting a battery voltage for the asynchronous machine, said charger having a mains power module which applies an AC voltage to one or two motor connection leads via a transformer, the charging current being rectified by half-bridges in the three-phase AC control unit.

Abstract: Charger for a battery which is connected to a plug via a charging cable and which cooperates with a socket connected to the battery, the plug comprising a plug housing in which plug pins connected to the charging cable are arranged and means being associated with the plug which react when the plug and socket are mechanically disconnected and the means generate a signal which causes the charger to switch off, characterised in that the plug comprises a handle which may be manually grasped and with which the plug is pulled out of the socket and a switching element is associated with the handle which is actuated upon disconnection and is connected to the charger via a signal path.
