Embodiment Construction

[0024] figure 1A system is shown comprising a replaceable battery pack 10 having a first electromechanical interface 14 with a plurality of electrical contacts 12 and an electrical device 16, in particular a charging device 18 . A diagnostic device 20 or an electrical consumer 22 having a further electromechanical interface 24 having a plurality of electrical contacts 12 . figure 1 It is intended to illustrate that the system according to the invention is suitable for different electrical devices 16 operated with exchangeable battery packs 10 , without limiting the invention. Here, a battery-operated vacuum cleaner 26 , a battery-powered hammer screwdriver 28 and a battery-powered lawn trimmer 30 are shown by way of example. In the context of the present invention, however, various power tools, garden appliances and domestic appliances can be considered as electrical consumers 22 . The number of replaceable battery packs 10 in the system is also variable. As such, the sys...

Abstract

The invention relates to a method for detecting electrical fault states of a removable battery pack, wherein cell voltage values of a plurality of energy storage cells of the removable battery pack are detected by a first monitoring unit integrated in the removable battery pack and a voltage of the removable battery pack is detected by a further monitoring unit integrated in an electrical device, in particular a charging device, a diagnostic device or an electrical consumer, that can be connected to the removable battery pack. Provision is made that in a method step, the cell voltage values detected by the first monitoring unit is transmitted to the further monitoring unit, wherein the further monitoring unit sums the cell voltage values and compares this with the voltage value of the removable battery pack. In addition, the invention also relates to a system comprising the removable battery pack and the electrical device, the method used for carrying out the method.

Description

technical field [0001] The invention relates to a method for detecting an electrical fault state of an exchangeable battery pack, wherein a plurality of energy storage cells of the exchangeable battery pack are detected by a first monitoring unit integrated in the exchangeable battery pack The voltage value of the unit cells, wherein the voltage of the replaceable battery pack is detected by an additional monitoring unit integrated in an electrical device that can be connected to the replaceable battery pack, in particular a charging device, a diagnostic device Or power consumption. Furthermore, the invention relates to a system for carrying out the method. Background technique [0002] The various consumers are operated by means of a battery pack which can be replaced by the operator without tools—hereinafter referred to as an exchangeable battery pack—which is accordingly discharged by the consumer and can be charged by means of The device charges again. Usually, such e...
