Abstract

A system for electrically coupling an electrical supply unit for cordless electrical devices, hand-held power tools in particular, with a charging device, with the electrical supply unit is located in a housing in which at least one rechargeable battery that can be recharged using the charging device is located, and the electrical supply unit and the charging device each have at least a first and a second contact element, wherein the first and second contact elements of the electrical supply unit interact with the first and second contact elements of the charging device such that the charging procedure takes place only when the electrical supply unit is in a defined end position in the charging device.
