A user input is captured and configuration information is determined depending on the user input. The configuration information is transferred to the battery pack (1) by means of an external computer system (10). The software is configured according to the configuration information and the first electric appliance (4) is controlled by means of the battery pack (1) by execution of the configured software.

Abstract: A method is disclosed for project support in using an electric appliance with a battery pack. The method includes storing project data relating to at least a part of a sequence of project steps on a data storage of the battery pack, wherein the project data includes, for each project step, associated user information. For a predetermined project step of the sequence of project steps, the associated user information is output in visual and/or acoustic form by means of an output device of the battery pack. The user information and/or further user information for the predetermined project step are output in visual and/or acoustic form and/or provided for retrieval by a user by means of at least one external computing unit.

Abstract: The invention relates to a battery management system for a lithium ion battery of an electrical appliance, in particular an electrical hand tool or electrical gardening tool, which is configured in order to determine a difference between a current required by the electrical appliance and a predetermined measuring current which can be provided electrochemically by means of the lithium ion battery, and to cover the difference using a dielectric capacitance of the lithium ion battery in so far as this does not result in departure from predetermined acceptable operating states of the lithium ion battery. The invention further relates to a method for operating a lithium ion battery of an electrical appliance.

Abstract: The invention relates to a portable storage battery, to an associated server device and to corresponding operating methods. The storage battery has a communication module for communicating with the server device and with a small vehicle, which can be operated by means of the storage battery. The storage battery is used as a key for enabling driving operation of the small vehicle. For this purpose, the storage battery transmits, in response to a corresponding authorization signal received from the server device, a corresponding enabling signal to the small vehicle.

Abstract: The invention relates to a system for monitoring and remote controlling the charge state of at least one battery pack comprising the at least one battery pack for an electric device which has a communication device that is designed to transmit charge state data of the battery pack to a server device of the system. The server device is designed to transmit the charge state data to at least one user interface of the system, wherein the user interface is designed to visualize the charge state data of the battery pack, and the user interface is additionally designed to transmit control data for actuating a charging device to the server device depending on a user input. The server device is designed to transmit the control data to the communication device, which is integrated into the battery pack, said communication device being designed to transmit the control data for a charging process of the battery pack to the charging device.
