Abstract

The invention relates to a replaceable battery pack (10) and / or an electrical device (18), having a first electromechanical interface (14) for supplying power to the electrical device (18); the invention relates to an electrical device (10) having a further electromechanical interface (20) for supplying energy by means of a replaceable battery pack (10), the electromechanical interfaces (14, 20) each having a plurality of electrical contacts (12) which can be connected to electrical contacts (12) of a mating interface (14, 20). According to the invention, the first and / or second electromechanical interface (14, 20) has a temperature sensor (76, 78) for sensing a temperature of the electromechanical interface (14, 20) and / or a temperature (T2, T3) of at least one of the electrical contacts (12), in particular during operation of the electrical consumer (18).

Description

technical field [0001] The invention relates to a replaceable battery pack and / or an electrical device, the replaceable battery pack has a first electromechanical interface for energy supply of the electrical device, and the electrical device has another electromechanical interface for Energy is supplied via an exchangeable battery pack, wherein the electromechanical interfaces each have a plurality of electrical contacts which can be connected to the electrical contacts of the mating interface. Background technique [0002] The various consumers are operated by means of battery packs which can be replaced by the operator without tools (hereinafter referred to as exchangeable battery packs), which are accordingly discharged by the consumers and can be recharged by means of a charging device . Usually, such a replaceable battery pack consists of a plurality of energy storage cells connected in series and / or in parallel in order to achieve the required voltage of the replacea...
