Device for identifying operating data of a motor-driven tool and system

A device for identifying operating data of a motor-driven tool, wherein the device is configured for arrangement on the tool, the device comprising:

• an identifying and/or evaluating device, wherein the identifying and/or evaluating device is configured to identify at least one parameter, wherein the parameter is a function of an operating state of the tool, and to evaluate the identified parameter for obtaining the operating data and/or to identify operating data;
• an operating data memory unit, wherein the operating data memory unit is configured to store the obtained and/or identified operating data;
• a communication interface, wherein the communication interface is configured to transfer the stored operating data to a terminal in a wire-less manner;
• a housing configured to be repeatedly and non-destructively opened and closed by a user;
• at least one elastic element,
• wherein the housing comprises a housing container body having top and bottom openings, the housing container body being configured to accommodate an electrical energy storage device through the top opening for electrical energy supply of the identifying and/or evaluating device, the operating data memory unit, and/or the communication interface, and being configured to accommodate the identifying and/or evaluating device, the operating data memory unit, and/or the communication interface through the bottom opening, wherein a portion of the housing container body is interposed between the electrical energy storage device from the identifying and/or evaluating device, the operating data memory unit, and/or the communication interface,
• wherein the housing has an open condition and a closed condition,
• wherein, in the open condition of the housing, the electrical energy storage device is insertable into the housing or removable from the housing through the top opening along an insertion and removal direction,
• wherein the at least one elastic element is configured, in the closed condition of the housing, to fix the accommodated electrical energy storage device by applying pressure of a force along the insertion and removal direction over a surface area of the electrical energy storage device facing the at least one elastic element,
• wherein the elastic element applies the pressure on the accommodated electrical energy storage device against the portion of the housing container body interposed between the electrical energy storage device and the identifying and/or evaluating device, the operating data memory unit, and/or the communication interface,
• wherein the force amounts to a value of the mass of the electrical energy storage device multiplied by at minimum 1 N per g.
