[0004] Methods for controlling and regulating a system

[0005] The present invention relates to a method for controlling and regulating a system with at least one accumulator and a device operable with the at least one accumulator, for example a machine tool, wherein the at least one accumulator includes at least one transceiver, at least one sensor and a storage unit and the device includes at least one sensor, one transceiver and a storage unit.

[0006] Furthermore, the invention relates to a system for carrying out the method.

[0007] Battery-powered devices, such as power tools (e.g., hammer drills, saws, grinders, screwdrivers, etc.), suction devices (e.g., vacuum cleaners), lamps, exoskeletons, etc., generate a large amount of data and information during their use. Power tools often have various sensors to capture this data and information.

[0008] The evaluation of this data and information is often crucial for the intended use, timely repair, and / or proper functioning of such devices. However, the actual collection and evaluation of this data only takes place once the corresponding machine tool has been delivered to a service facility.

[0009] The problem with existing methods is that too much time elapses between data collection and data analysis. This causes the collected data to lose relevance and potentially become unusable.

[0010] The object of the present invention is to solve the problem described above.

[0011] The problem is also solved by the subject matter of claim 1 as well as by the subject matter of claim 14.

[0012] Further advantageous embodiments of the invention are described in the corresponding dependent claims.

[0013] The problem is solved in particular by a method for controlling and regulating a system with at least one accumulator and a device operable with the at least one accumulator, for example a machine tool, wherein the at least one accumulator includes at least one transceiver, at least one sensor and a storage unit, and the device includes at least one sensor, one transceiver and a storage unit.

[0014] According to the invention, the following process steps are provided.

[0015] - Capturing at least one characteristic value by the at least one sensor of the accumulator and / or by the at least one sensor of the device;

[0016] - Sending the data captured by at least one sensor of the device to the accumulator;

[0017] - Sending the captured data to a first transmitting and receiving device if the accumulator's transceiver is connected to the first transmitting and receiving device, or sending the captured data to a second transmitting and receiving device if the accumulator's transceiver is connected to the second transmitting and receiving device; and

[0018] - Sending the captured data from the first and / or second transmitting and receiving device to a data storage and computing device.

[0019] The data storage and computing device can also be referred to as a cloud or cloud computer.

[0020] According to an advantageous embodiment, the process step may include:

[0021] - Sending at least one data record from the data storage and computing device via the first and / or second transmitting and receiving device to the accumulator, if the received data corresponds to at least one threshold stored in the data storage and computing device.

[0022] According to another advantageous embodiment, the process step may include:

[0023] - Sending at least one data record from the accumulator to the device to replace the corresponding data, if the received data corresponds to at least one threshold stored in the data storage and computing device.

[0024] According to a further advantageous embodiment, the process step can include: - Sending at least one data record from the data storage and computing device to the accumulator via the first and / or second transmitting and receiving device after a first or second period of time has elapsed. This makes it possible, for example, to send new, permanently implemented software (i.e., firmware) at regular or irregular intervals (e.g., every 30 days).

[0025] According to another advantageous embodiment, the process step may include:

[0026] - Marking the recorded data by time verification using a real-time clock.

[0027] According to another advantageous embodiment, the process step may include: - Marking the recorded data by means of a proof of origin.

[0028] Proof of origin can be provided, for example, in the form of a device identification number. GPS data can also serve as proof of origin.

[0029] According to another advantageous embodiment, the process step may include:

[0030] - Sending at least a first and second signal through the accumulator to indicate to a transmitting and receiving device that the accumulator is ready to send data to the transmitting and receiving device and / or to receive data from the transmitting and receiving device.

[0031] This allows the accumulator to act as a so-called beacon (lighthouse or signal station).

[0032] According to another advantageous embodiment, the process step may include: - storing the captured data in a storage unit of the device before sending the captured data to the accumulator.

[0033] This allows recorded data to be backed up as a precaution if either no accumulator is connected to the machine tool or if the accumulator is not ready to receive and store the data from the machine tool.

[0034] According to another advantageous embodiment, the process step may include:

[0035] - Storing at least a portion of the captured or received data in a storage unit of the accumulator before transmitting the captured data to a transmitting and receiving device. This allows captured data to be backed up as a precaution if either no transmitting and receiving device is available or if the transmitting and receiving device is not ready to receive and store the data.

[0036] According to another advantageous embodiment, the process step may include: - Processing / modifying at least a portion of the captured or received data by the accumulator.

[0037] Processing involves modifying and extending at least a portion of the captured or received data by the accumulator. Extending involves adding at least one piece of additional information to at least a portion of the captured or received data by the accumulator.

[0038] According to another advantageous embodiment, the process step may include:

[0039] - Sending at least a first subset of the recorded data to a first sending and receiving device and sending at least a second subset of the recorded data to a second sending and receiving device.

[0040] According to another advantageous embodiment, the process step can include:

[0041] - Sending at least a first subset of the recorded data from a first sending and receiving device (e.g. battery charger) to a data storage and computing device (= cloud) at a first time, and sending at least a second subset of the recorded data to a data storage and computing device (= cloud) at a second time.

[0042] According to another advantageous embodiment, the process step may include:

[0043] - Comparing the recorded data with priority data stored in the accumulator's memory unit; and

[0044] - Sending an initial data set according to a first priority and sending a second data set according to a second priority.

[0045] The task is further solved by a system for carrying out the procedure.

[0046] According to an advantageous embodiment, the first and / or second transmitting and receiving device may be designed as part of a charging device, a smartphone, a gateway device, or a base station of a radio signal transmission device. Further advantages will become apparent from the following description of the figures. The figure illustrates a particularly preferred embodiment of the present invention.

[0060] Figure 1 shows an exemplary system S comprising a device 1 and an accumulator 2 connected to the device 1.

[0061] According to the embodiment shown in Figure 1, the device 1 is designed in the form of a machine tool. This machine tool is a cordless screwdriver.

[0062] Alternatively, the machine tool 1 can also be designed as a hammer drill, drill, saw, grinder or the like.

[0063] The device 1, designed as a machine tool, essentially comprises a housing 3, a handle 4, and a tool holder 5. Inside the housing 3 are positioned a drive 6 in the form of a brushless electric motor, a gear unit 7, an output shaft 8, a control unit 9, a storage unit 10, a number of sensors 21a, 21b, 21c, 21d, 21e, and a transceiver 11.

[0064] The transceiver can also be described as a transmitting and receiving device for electrical signals.

[0065] The drive 6, designed as an electric motor, the gear unit 7, and the output shaft 8 are arranged relative to each other such that a torque generated by the electric motor 6 can be transmitted via the output shaft 8 and the gear unit 7 to the tool holder 5. The tool holder 5 is positioned at a front end 3a of the housing 3 and is designed to receive and hold a tool.

[0066] In the case of a cordless screwdriver, the tool can be designed as a screwdriver bit. The tool is not shown in the figures.

[0067] The handle 4 is positioned on the underside 3b of the housing 3. The handle 4 is attached to the underside 3b of the housing 3 at one end 4a. A machine tool interface 12 is positioned at the other end 4b of the handle 4 and serves for the electrical / electronic and mechanical connection of the machine tool 1 to the accumulator 2. For electrical / electronic connection, the machine tool 1 has a positive contact 13a, a negative contact 13b, and a communication contact 13c. The positive and negative contacts 13a and 13b are used to create an electrical circuit when the accumulator 2 is connected to the machine tool 1. The communication contact 13c is used for sending and receiving data and information in the form of electrical signals. An actuating switch 14 is provided at the front end 4c of the handle 4. The actuating switch 14 is used to activate the machine tool 1.

[0068] Inside the handle 4 is the control unit 9 with the transceiver 11, the sensors 21a, 21b, 21c, 21d, 21e and the memory unit 10. The control unit 9 controls and regulates the individual functions of the machine tool 1. These functions include, for example, setting a specific speed of the electric motor 6.

[0069] The sensors 21a, 21b, 21c, 21d, 21e of the machine tool 1 are a sensor 21a for detecting a current value, a sensor 21b for detecting a voltage value, a sensor 21c for detecting the operating time of the machine tool 1, a sensor 21d for detecting an orientation value of the machine tool 1 in a free space, and a sensor 21e for detecting a temperature value.

[0070] The 2D orientation sensor can be designed as a gyroscope.

[0071] The sensor 21c for recording the operating time of the machine tool 1 can be designed as a real-time clock (also known as a Real Time Clock (RTC)).

[0072] The sensor 21a for detecting a current value, the sensor 21b for detecting a voltage value and the sensor 21e for detecting a temperature value are used to detect measured values ​​of the drive 6.

[0073] The accumulator 2 can be reconnected to a machine tool 1 in a reversible manner in order to supply the machine tool 1 with electrical energy which is stored within the accumulator 2.

[0074] The accumulator 2 essentially contains a battery housing 15, a number of energy storage cells 16, a battery interface 17, a storage unit 18, a transceiver 19, a control unit 20 and a variety of sensors 30, 31, 32, 33, 34, 35.

[0075] The transceiver 19 can also be described as a transmitting and receiving device for electrical signals.

[0076] The energy storage cells 16 can also be called battery cells and are arranged inside the battery housing 15.

[0077] The battery housing 15 essentially contains a lid element 15a, four side walls 15b and a bottom element 15c.

[0078] The battery interface 17 is located on the outside of the cover element 15a and serves for the electrical, electronic, and mechanical connection of the battery 2 to the machine tool 1 or a charging device 22. For electrical and electronic connection, the battery interface 17 has a positive contact 17a, a negative contact 17b, and a communication contact 17c. The positive and negative contacts 17a and 17b are used to create a circuit when the battery 2 is connected to a machine tool 1 or a charging device 22. The communication contact 17c is used for sending and receiving data and information in the form of electrical signals. The communication contact 17c is connected to the transceiver 19.

[0079] The data and information include, among other things, (execution) commands (also called commands) as well as parameters and / or characteristic values ​​of the machine tool 1.

[0080] Alternatively or additionally, the accumulator 2 can also include radio communication (e.g. Bluetooth) or wireless communication.

[0081] The energy storage cells 16 serve to absorb, store, and release electrical energy. As indicated in the figures, the energy storage cells 16 are cylindrical and based on lithium-ion technology. Each energy storage cell 16 has a contact device at one end for transferring electrical energy. The individual contact devices are connected to the control unit 20 of the accumulator 2 via corresponding lines.

[0082] Alternatively, the energy storage cells 16 can also be based on another suitable technology.

[0083] The cylindrical shape of the energy storage cells 16 is also optional, so any other suitable shape or geometry can be chosen. In particular, it is also possible for the energy storage cells 16 to be designed as pouch cells.

[0084] It is also possible that the accumulator 2 contains both cylindrical energy storage cells 16 and pouch cells. In particular, it is possible that the accumulator 2 contains only a single cylindrical energy storage cell 16 and a single pouch cell.

[0085] The control unit 20 regulates and controls various functions of the accumulator 2. These functions include, among others, the control of the input and output of electrical energy into and out of the energy storage cells 16.

[0086] Furthermore, the control unit 20 controls the amount of electrical energy to be absorbed or released by the energy storage cells 16. A first set of control parameters, containing a multitude of control parameters, is stored in the storage unit 18. These control parameters can also be referred to as control characteristics or setting parameters. The control unit 20 is also connected to the transceiver 19, thus regulating and controlling the transmission and reception of electrical signals to and from the transceiver 19.

[0087] The storage unit 18 is connected to the control unit 20 in such a way that the control unit 20 can access the individual control parameters stored in the storage unit 18 and use these control parameters to control the functions of the accumulator 2. The control parameters include maximum discharge currents (current value), maximum charging currents (current value), minimum and maximum charging times, minimum and maximum internal resistances, and minimum and maximum capacity values ​​(in Ah).

[0088] The control parameters also include a procedure for reducing or completely blocking the energy absorption or output by the energy storage cells 16.

[0089] The storage unit 18 of the accumulator 2 serves, among other things, to store so-called charge and discharge cycles of the accumulator 2. A charge cycle refers to a charging process in which electrical energy is absorbed by the energy storage cells 16. A discharge cycle refers to a discharge process in which electrical energy is released by the energy storage cells 16.

[0090] The information contained in a charging cycle also includes the energy absorbed by the energy storage cells 16, the charging current (in amperes), the charging voltage (in volts), the capacity (%) at the beginning of the charging process, the capacity (%) at the end of the charging process, the number of charging processes, and the charging time.

[0091] The information for a discharge cycle also includes the energy delivered by the energy storage cells 16, the discharge current (in amperes), the discharge voltage (in volts), the capacity (%) at the beginning of the charging process, the capacity (%) at the end of the discharge process, the number of discharge processes, and the discharge time.

[0092] The corresponding values ​​are recorded by the respective sensors of accumulator 2.

[0093] Accumulator 2 also contains a number of sensors 30, 31, 32, 33, 34, 35 for recording operating characteristics. These operating characteristics can also be referred to as operating parameters, operating parameters, characteristic values, parameters, or operating quantities.

[0094] In particular, the accumulator 2 contains a sensor 30 for detecting charging and discharging current, a sensor 31 for detecting charging and discharging time, a sensor 32 for detecting acceleration and deceleration values, a sensor 33 for detecting temperature values, a sensor 34 for detecting internal resistance values, and a sensor 35 for detecting capacity. Using sensors 30, 31, 32, 33, 34, and 35 of the accumulator 2, it is particularly possible to detect the SoH (State of Health) and SoC (State of Charge) of the accumulator 2.

[0095] The sensor 32 for detecting a braking value can also be referred to as a sensor for detecting a deceleration value.

[0096] The sensor for recording a charging and discharging time 31 can also be called a clock, real-time clock or real-time clock (= RTC).

[0097] The acceleration value can be described as a value for positive acceleration, and the braking value can also be described as a value for negative acceleration.

[0098] The sensor 33 for recording temperature values ​​can also be referred to as a thermometer or temperature measuring device.

[0099] The sensor 34 for detecting internal resistance values ​​can also be called an ohmmeter.

[0100] The sensor 35 for measuring capacity can also be referred to as a sensor for measuring ampere-hours (Ah).

[0101] Figure 4 shows the charging device 22, which essentially comprises a charger housing 23, a control unit 24, a storage unit 26, a power supply 27 and a transmitting and receiving device 40 with a transceiver 25.

[0102] The loader housing 23 essentially comprises a cover element 23a, four side walls 23b and a bottom element 23c.

[0103] A charging interface 28 is positioned on the cover element 23a and serves to electrically or electronically as well as mechanically connect the charging device 22 to the accumulator 2.

[0104] According to an alternative embodiment, more than one charging interface 28 may also be present on the charging device 22.

[0105] For electrical or electronic connection, the charger interface 28 has a positive contact 28a, a negative contact 28b, and a communication contact 28c. The positive and negative contacts 28a and 28b are used to create a circuit when the accumulator 2 is connected to the charging device 22. The communication contact 28c is used to send and receive data and information in the form of electrical signals.

[0106] Alternatively or additionally, the charging device 22 can also include radio communication (e.g., Bluetooth) or wireless communication. The power supply 27 of the charging device 22 is designed in the form of a power cable for connection to a mains power source (i.e., socket) not shown.

[0107] Inside the charger housing 23 are positioned the control unit 24, the transmitting and receiving unit 40 with the transceiver 25 and the storage unit 26.

[0108] The control unit 24 controls and regulates the individual functions of the charging device 22. These functions include, among others, setting a charging current (i.e., the current value) when a battery 2 is releasably connected to the charging device 22 for charging. The transmitting and receiving device 40 with the transceiver 25 is used for transmitting and receiving data and information.

[0109] According to the present embodiment, the transmitting and receiving device 40 is designed as part of a charging device 22 in the form of a WiFi device.

[0110] Alternatively, the transmitting and receiving device 40 can also be designed in the form of a Bluetooth device.

[0111] As indicated in Figure 5, the charging device 22 is specifically designed to exchange various data and information with a data storage and computing device 29. The data storage and computing device 29 comprises a transceiver 37, a computing unit 38, and a storage unit 39. The data storage and computing device 29 can also be referred to as a cloud or cloud computer.

[0112] The transceiver 37 is designed so that data and information can be exchanged with the transceiver 25 of the charging device 22 or so that data and information can be exchanged with the transceiver 19 of the accumulator 2.

[0113] Alternatively or additionally, the transceiver 37 of the transmitting and receiving device 40 of the charging device 22 is designed so that data and information can be exchanged with the transceiver 19 of the accumulator 2.

[0114] Furthermore, it is also possible that the transceiver 19 of the accumulator 2 exchanges data and information with both the transceiver 25 of the charging device 22 and the transceiver 37 of the transmitting and receiving device 40 of the charging device 22. Exchange means that data and information can be sent and received.

[0115] As shown in Figure 6, the accumulator 2 is physically connected to the device 1, which is configured as a machine tool. Through this physical connection, electrical energy can be transferred from the accumulator 2 to the consumers of the machine tool 1. The accumulator 2, and in particular its transceiver 19, is designed such that the transceiver 19 exchanges various data and information with the transceiver 25 of the charging device 22 and / or with the transceiver 37 of the transmitting and receiving unit 40 of the charging device 22 when the accumulator 2 is physically connected to the machine tool 1.

[0116] As also indicated in Figure 6, the accumulator 2, and in particular the transceiver 19 of the accumulator 2, as well as the transceiver 11 of the machine tool 1, are configured such that the transceiver 11 of the machine tool 1 exchanges data and information of a first kind (i.e., a first data record) with a transceiver 19 of a first accumulator 2a and simultaneously data and information of a second kind (i.e., a second data record) with a transceiver 19 of a second accumulator 2b. According to the present embodiment, the data and information exchange between the transceiver 19 of the first accumulator 2a and the transceiver 11 of the machine tool 1 is wired.

[0117] Furthermore, according to the present embodiment, the data and information exchange between the transceiver 19 of the second accumulator 2b and the transceiver 11 of the machine tool 1 takes place wirelessly (i.e. via Bluetooth connection).

[0118] As shown in Figure 6a, the accumulator 2 and in particular the transceiver 19 of the accumulator 2 is designed such that the transceiver 19 of the accumulator 2 also exchanges data and information with the transceiver 25 of the charging device 22 and / or with the transceiver 37 of the transmitting and receiving device 40 of the charging device 22, even if the accumulator 2 is not physically connected to the charging device 22.

[0119] As indicated in Figure 6a, data and information exchange in this embodiment is wireless (e.g., via Bluetooth). According to this embodiment, the accumulator 2 is not connected to the device 1, which is configured as a machine tool. "Connection" here refers to a wireless or wired connection between the accumulator 2 and the machine tool 1. As also indicated in Figure 6a, the charging device 22 and its transmitting and receiving unit are designed such that data and information can be exchanged simultaneously between the charging device 22 and multiple accumulators 2a, 2b. This is also possible if a third accumulator 2 is physically connected to the charging device 22 for charging at the same time.

[0120] As shown in Figure 7, according to a further embodiment, the transmitting and receiving device 40 can also be designed as a component of a smartphone 50. The transmitting and receiving device 40 also includes a transceiver 51 for wirelessly transmitting and receiving data and information.

[0121] Furthermore, according to another embodiment, the transmitting and receiving device 40 can also be designed as part of a base station 60 of a transmission device for radio signals.

[0122] Furthermore, according to another embodiment, the transmitting and receiving device 40 can also be designed as part of a gateway device 70.

[0123] To carry out the method according to the invention, in an exemplary embodiment, the accumulator 2 is first connected to the device 1, which is designed as a machine tool, so that electrical energy can flow from the energy storage cell 16 to the consumers of the machine tool 1, cf. Figure 1. The device 1, which is designed as a machine tool, and the accumulator 2 form a system S.

[0124] As shown in Figure 1, the respective interfaces of the accumulator 2 and the machine tool 1 are detachably connected. This connection allows data and information in the form of electrical signals to be exchanged between the accumulator 2 and the machine tool 1. The respective transceivers 19 and 25, as well as the interconnected communication contacts 13c and 17c of the accumulator 2 and the machine tool 1, are used to send and receive these electrical signals.

[0125] Alternatively, the connection between machine tool 1 and accumulator 2 can also be wireless. A wireless connection can be implemented as a Bluetooth connection.

[0126] When machine tool 1 is connected to battery 2 and supplied with electrical power, the sensors of machine tool 1 acquire various data and information. This data and information can be referred to as operating parameters of machine tool 1. Using sensor 23, which records the operating time of machine tool 2, the acquired data is assigned a corresponding time stamp. This time stamp allows, for example, multiple acquired data points or data sets to be sorted chronologically or assigned to specific events. Furthermore, an identification code is added to the data acquired by the sensors of machine tool 1. This identification code is specific to the device (or machine tool) 1, so that it can be determined from the data which device 1 it was acquired in.

[0127] While the accumulator 2 is used to power the machine tool 1, its sensors also record numerous data points and information in the form of various operating parameters. Specifically, the duration that the accumulator 2 is connected to the machine tool 1 is recorded. Furthermore, the discharge voltage, discharge current, and the identification code of the machine tool 1 are also recorded. By recording the identification code of each machine tool, a history of the machines 1 to which the accumulator 2 has been connected is documented.

[0128] It is possible that only some of the sensors collect data and information. The operating parameters recorded by the sensors are stored in memory unit 18 of accumulator 2.

[0129] As indicated in Figure 5, the accumulator 2 can be removed from the machine tool 1 and reconnected to the charging device 22. The energy storage cells 16 of the accumulator 2 can be charged with electrical energy using the charging device 22.

[0130] The respective interfaces of the accumulator 2 and the charging device 22 are releasably connected to each other such that the respective communication contacts 17c, 28c of the accumulator 2 and the charging device 22 are in contact with each other. Through the connection of the accumulator 2 to the charging device 22, data and information in the form of electrical signals can also be exchanged between the accumulator 2 and the charging device 22. The respective transceivers 19, 25 of the accumulator 2 and the charging device 22 serve to send and receive the electrical signals.

[0131] The charging device 22 stores the received operating parameters in the storage unit 24 of the charging device 22.

[0132] When the charging device 22 is connected to the data storage and computing device 29, the operating parameters are sent to the data storage and computing device 29. Data relating to the operating time(s) are stored in the data storage and computing device 29 in such a way that they are available for further processing at any time. The data storage and computing device 29 also contains threshold values ​​for the corresponding operating parameters, which were detected by the sensors of the accumulator 2 or received by the machine tool 1.

[0133] Furthermore, the data storage and computing device contains 29 individual control parameters as well as complete sets of control parameters for a large number of different accumulators 2 and machine tools 1.

[0134] The recorded operating parameters are compared with the respective threshold values ​​in the data storage and computing device 29. If an operating parameter exceeds a corresponding threshold value, a new control parameter for the accumulator 2 and / or for the machine tool 1 is sent from the data storage and computing device 29 to the charging device 22. The new control parameter is then sent from the charging device 22 to the connected accumulator 2. In the control unit 20 of the accumulator 2, the received new control parameter is used to replace or supplement a corresponding control parameter. This corresponding control parameter can also be referred to as the previous or old control parameter.

[0135] A new control parameter for machine tool 1 can be transferred from the charging device 22 to the accumulator 2 and stored there. When the accumulator 2 is connected to machine tool 1, the new control parameter is sent from the accumulator 2 to the machine tool 1. The new control parameter replaces or supplements an existing control parameter in machine tool 1.

[0136] According to an alternative embodiment, it is also possible that more than one new control parameter is sent from the data storage and computing device 29 to the charging device 22 if more than one operating characteristic exceeds the corresponding threshold values. It is also possible that one or more new control parameters are sent from the data storage and computing device 29 to the charging device 22 even if one or more recorded operating characteristics do not yet exceed the corresponding threshold values, but merely correspond to these threshold values.

[0137] Figure 6b shows a system S with a device 1 configured as a machine tool connected to an accumulator 2. Data acquired by the sensors of the accumulator 2 and by the sensors of the machine tool 1 are stored in the storage unit 18 of the accumulator 2.

[0138] Furthermore, a first transmitting and receiving unit 40 and a second transmitting and receiving unit 40' are located near the system S. The first transmitting and receiving unit 40 is in the form of a gateway unit 70 (also known as gateway), and the second transmitting and receiving unit 40' is designed as a previously described charging device 22. The gateway unit 70 contains a Bluetooth module 71 and a WiFi module 72. The Bluetooth module 71 can be referred to as the first transceiver, and the WiFi module 72 can be referred to as the second transceiver.

[0139] The Bluetooth module 71 enables the gateway device 70 to receive and send various data and information to the accumulator 2. The WiFi module 72 allows various data and information to be sent to and received from a data storage and computing device (= cloud) 29. As shown in Figure 6b, the first transmitting and receiving device 40, designed as a gateway device 70, is positioned closer to the accumulator 2 than the second transmitting and receiving device 40, designed as a charging device 22.

[0140] Because the first transmitting and receiving device 40 is located near the accumulator 2, the transceiver of the accumulator 2, designed as a Bluetooth module 71, can establish a connection to the (first) transceiver of the first transmitting and receiving device 40, also designed as a Bluetooth module 71. Once the connection between the accumulator 2 and the first transmitting and receiving device 40 is established, the data stored in the memory unit 18 is sent to the first transmitting and receiving device 40.

[0141] It is also possible that only an initial portion of the data stored in the memory unit 18 of the accumulator 2 is sent to the first transmitting and receiving device 40. If the accumulator 2 moves away from the first transmitting and receiving device 40, or if a certain distance exists between the accumulator 2 and the first transmitting and receiving device 40, the connection between the accumulator 2 and the first transmitting and receiving device 40 can be interrupted. Without this connection, no further data is sent from the accumulator 2 to the first transmitting and receiving device 40.When the accumulator 2 of the second transmitter and receiver 40' approaches sufficiently, the transceiver of the accumulator 2, designed as a Bluetooth module 71, can establish a connection to the transceiver of the second transmitter and receiver 40, also designed as a Bluetooth module 71 and designed as a charging device 22. Once the connection between the accumulator 2 and the second transmitter and receiver 40' is established, a second portion (or the entire remainder) of the data stored in the memory unit 18 of the accumulator 2 is sent to the second transmitter and receiver 40'.

[0142] A continuous exchange of data transmission from the accumulator 2 to either the first or second transmitting and receiving device 40, 40' is possible. Furthermore, it is also possible that instead of one or more new control parameters to replace the corresponding control parameters, a completely new set of control parameters is sent from the data storage and computing device 29 to the charging device 22 and finally to the accumulator 2 or to the machine tool 1.

[0143] Furthermore, the control unit 20 and the transceiver 19 of the accumulator 2 are configured such that previously acquired data is sent to a transmitter and receiver 40 as soon as and as long as contact (i.e., radio link or physical contact) exists between the accumulator 2 and this transmitter and receiver 40. If the contact between the accumulator 2 and the transmitter and receiver 40 is interrupted before all data has been completely transmitted from the accumulator 2 to the transmitter and receiver 40, data transmission resumes as soon as contact is re-established. However, the further data transmission need not be to the original transmitter and receiver 40. Instead of the original transmitter and receiver 40, the data remaining in the accumulator 2 can also be sent to another transmitter and receiver 40.

[0144] Furthermore, the control unit 20 of the accumulator 2 contains priorities or priority data that regulate the order in which acquired data is transmitted from the accumulator 2 to an available transmitter and receiver 40. Certain data, such as information regarding the operating and run times of a machine tool 1 or error messages from a machine tool 1, must be sent with higher urgency (i.e., faster and earlier) via a transmitter and receiver 40 to the data storage and computing device (= cloud) 29. Other data, which is less urgent and / or important, can, however, be sent later or after the urgent data has been sent. Less important data includes, for example, data acquired by the sensor for recording orientation values ​​of the machine tool 1 in a room. Important and urgent data thus had a first or second priority.Data with higher priority, and less important or less urgent data, have a second or lower priority.

[0145] Figure 8 shows a system S consisting of a device 1 configured as a machine tool connected to an accumulator 2. As indicated, the accumulator 2 is in wireless communication with a first transmitting and receiving device 40 configured as a smartphone 50. Through the wireless (radio) connection between the accumulator 2 and the smartphone 50, data and information previously acquired by sensors of the accumulator 2 and / or the machine tool 1 can be transmitted to the smartphone 50. Furthermore, the first transmitting and receiving device 40 configured as a smartphone 50 is in wireless (radio) communication with a second transmitting and receiving device 40' configured as a (mobile communication) transmission tower. The (mobile communication) transmission tower can also be referred to as a base station 60.By connecting the first transmitting and receiving device 40 with the second transmitting and receiving device 40', data and information temporarily stored in the smartphone 50 can be sent to the second transmitting and receiving device 40'. The second transmitting and receiving device 40' sends this data and information to a data storage and computing device (= cloud) 29.

[0146] Figure 9 again shows a system S consisting of a device 1 designed as a machine tool connected to an accumulator 2. As indicated, the accumulator 2 is in wireless communication with a transmitting and receiving device 40 designed as a (mobile communication) transmission tower. Through the wireless (radio) connection of the accumulator 2 with the (mobile communication) transmission tower 60, data and information previously acquired by sensors of the accumulator 2 and / or the machine tool 1 can be transmitted to the (mobile communication) transmission tower. The transmitting and receiving device 40, designed as a (mobile communication) transmission tower 60, sends this data and information to a data storage and computing device (= cloud) 29.

[0147] Figure 10 again shows a system S consisting of a device 1 configured as a machine tool connected to an accumulator 2. As indicated, the accumulator 2 is in wireless communication with a transmitter and receiver 40 configured as a gateway device 70. Through the wireless (radio) connection of the accumulator 2 with the (mobile communication) transmission tower, data and information previously acquired by sensors of the accumulator 2 and / or the machine tool 1 can be transmitted to the (mobile communication) transmission tower 60. The (mobile communication) transmission tower 60 (equipped with the transmitter and receiver 40) sends this data and information to a data storage and computing device (= cloud) 29.
