These rechargeable batteries usually comprise a plurality of energy storage cells, also referred to as rechargeable battery cells, which are used and designed to receive, store and deliver electrical energy. The reception of electrical energy into the energy storage cells can also be referred to as charging (or recharging). The delivery of electrical energy from the energy storage cells can also be referred to as discharging.

[0004] For charging or recharging with electrical energy, the rechargeable battery is usually connected to a charging device, also referred to as a charger.

DETAILED DESCRIPTION

[0043] Figure 1 A power tool 1a, 1b connected to a rechargeable battery 2a, 2b is shown. In the present exemplary embodiment, the power tool 1a, 1b is designed as a cordless screwdriver.

The tool fitting 5 is positioned at a front end 3a of the housing 3 and serves to receive and hold a tool.

[0046] In the embodiment of a cordless screwdriver, the tool can be designed as a screwdriver bit. The tool is not shown in the figures.

[0047] The handle 4 is positioned on a lower side 3b of the housing 3. The handle 4 is fastened to the lower side 3b of the housing 3 by a first end 4a. A power tool interface 12 is positioned at a second end 4b of the handle 4 and serves to electrically or electronically and mechanically connect the power tool 1 to the rechargeable battery 2. For the electrical or electronic connection, the power tool 1 has a positive contact 13a, a negative contact 13b and a communication contact 13c. The positive contact 13a and the negative contact 13b serve to create a circuit when the rechargeable battery 2 is connected to the power tool 1. The communication contact 13c serves to transmit and receive data and information in the form of electrical signals.

[0048] An actuation switch 14 is arranged at the front end 4c of the handle 4. The actuation switch 14 is used to activate the power tool 1. The control unit 9 is positioned inside the handle 4 together with the transceiver 11 and the storage unit 10. The individual functions of the power tool 1 are controlled and regulated by means of the control unit 9. These functions include, for example, setting a specific speed of the electric motor 6.

[0049] The sensors 40 of the power tools 1a, 1b are each used to record characteristic operating values of the power tools 1a, 1b.

[0050] Alternatively, the power tool 1 can also be embodied as a hammer drill, a drill, a saw, a sander, etc.

[0051] The rechargeable battery 2 can be removably connected to the power tool 1 in order to supply the power tool 1 with electrical energy. The rechargeable battery 2 essentially comprises a rechargeable battery housing 15, a plurality of energy storage cells 16, a rechargeable battery interface 17, a storage unit 18, a transceiver 19, a control device 20 and a plurality of sensors.

[0052] The energy storage cells 16 can also be designated as rechargeable battery cells and are arranged inside the rechargeable battery housing 15.

[0053] The rechargeable battery housing 15 essentially comprises a cover element 15a, four side walls 15b and a base element 15c.

[0054] The rechargeable battery interface 17 is arranged on the outside of the cover element 15a and serves to electrically or electronically and mechanically connect the rechargeable battery 2 to the power tool 1 or to a charging device 22.

[0055] For the electrical or electronic connection, the rechargeable battery interface 17 has a positive contact 17a, a negative contact 17b and a communication contact 17c. The positive contact 17a and the negative contact 17b serve to create a circuit when the rechargeable battery 2 is connected to the power tool 1 or to the charging device 22. The communication contact 17c serves to transmit and receive data and information in the form of electrical signals.

[0056] Alternatively or additionally, the rechargeable battery can also comprise a radio communication, for example Bluetooth, or a wireless communication.

[0057] The energy storage cells 16 serve to receive, store and re-deliver electrical energy. As indicated in the drawing, the energy storage cells 16 are cylindrical and are based on lithium-ion technology. Each energy storage cell 16 contains contact devices for the transmission of electrical energy at one end. The individual contact devices are connected to the control device 20 of the rechargeable battery 2 via corresponding lines.

[0058] Alternatively, the energy storage cells 16 can also be based on another suitable technology.

[0059] The cylindrical shape of the energy storage cells 16 is also optional, so that any other suitable shape or geometry can also be chosen. Thus, in particular, it is also possible that the energy storage cells 16 are configured as pouch cells.

[0060] In addition, it is also possible that the rechargeable battery 2 comprises both cylindrical energy storage cells 16 and pouch cells. It is in particular possible that the rechargeable battery 2 comprises only a single cylindrical energy storage cell 16 and a single pouch cell.

[0061] The control device 20 regulates and controls various functions of the rechargeable battery 2. These functions include, inter alia, controlling the reception of electrical energy into the energy storage cells 16 and the delivery of electrical energy from the energy storage cells. Furthermore, the control device 20 serves to control the amount of electrical energy to be received or delivered by the energy storage cells 16.

[0062] A first set of regulation parameters comprising a plurality of regulation parameters is stored in the storage unit 18. The regulation parameters can also be referred to as regulation variables or setting parameters.

[0063] The storage unit 18 is connected to the control device 20, so that the control device 20 has access to the individual regulation parameters stored in the storage unit 18 and can use these regulation parameters to control or regulate the functions of the rechargeable battery 2. The regulation parameters include a maximum discharge current (current intensity value), a maximum charge current (current intensity value), a minimum charge time and a maximum charge time, a minimum internal resistance and a maximum internal resistance, and a minimum capacity value and a maximum capacity value (in Ah).

[0064] The regulation parameters also include methods for reducing or completely preventing the energy storage cells 16 from receiving or delivering energy in the event of a maximum acceleration value or braking value, a predetermined number of braking values within a predetermined threshold value, and a minimum temperature value and a maximum temperature value.

[0065] The rechargeable battery 2 also comprises, in each case, sensors for recording characteristic operating values. The characteristic operating values can also be referred to as operating parameters, operating variables or operating values.

[0066] In particular, the rechargeable battery 2 comprises sensors 30 for recording the charge current intensity and the discharge current intensity, a sensor 31 for recording the charge time, a sensor 32 for recording the acceleration values and the braking values, a sensor 33 for recording the temperature values, a sensor 34 for recording the internal resistance values, a sensor 35 for recording the capacity, and a counter 36 for the number of times the acceleration values exceed a predetermined threshold value.

[0067] The sensor 31 for recording the charge time can also be referred to as a clock or a real-time clock.

[0068] The acceleration values can be referred to as positive acceleration values, and the braking values can also be referred to as negative acceleration values.

[0069] The sensor 33 for recording temperature values can also be referred to as a thermometer or a temperature meter.

[0070] The sensor 34 for recording internal resistance values can also be referred to as an ohmmeter.

[0071] The sensor 35 for recording the capacity can also be referred to as a sensor for recording ampere-hours (Ah).

[0072] According to alternative embodiments of the system or the rechargeable battery 2, the rechargeable battery 2 can comprise more or less sensors.

[0073] Figure 4 A charging device 22 is shown, which essentially comprises a charger housing 23, a control unit 24, a transceiver 25, a storage unit 26 and a power supply 27. The charger housing 23 essentially comprises a cover element 23a, four side walls 23b and a base element 23c.

[0074] A charger interface 28 is positioned on the cover element 23a and serves to electrically or electronically and mechanically connect the charging device 22 to the rechargeable battery 2. For the electrical or electronic connection, the charger interface 28 has a positive contact 28a, a negative contact 28b and a communication contact 28c. The positive contact 28a and the negative contact 28b serve to create a circuit when the rechargeable battery 2 is connected to the charging device 22. The communication contact 28c serves to transmit and receive data and information in the form of electrical signals.

[0075] Alternatively or additionally, the charging device 22 can also comprise a radio communication (e.g. Bluetooth) or a wireless communication.

[0076] The power supply 27 of the charging device 22 is in the form of a power cable for connection to a not shown mains power supply (i.e. a socket).

[0077] The control unit 24, the transceiver 25 and the storage unit 26 are positioned inside the charger housing 23. The control unit 24 controls and regulates the individual functions of the charging device 22. These functions include, inter alia, setting the charging current (i.e. the current intensity value) when the rechargeable battery 2 is removably connected to the charging device 22 for charging. The transceiver 25 serves to transmit and receive data and information in the form of electrical signals.

[0078] As Figure 5 indicated, the charging device 22 is in particular designed to exchange data and information with a data storage and computing device 29. The data storage and computing device 29 contains a transceiver 37, a computing unit 38 and a storage unit 39.

[0079] The data storage and computing device 29 can also be referred to as a cloud or a cloud computer.

[0080] To perform the method, first the rechargeable battery 2 is connected to the power tool 1 so that electrical energy from the energy storage cells 16 can reach the load of the power tool 1, see Figure 1 The respective interfaces of the rechargeable battery 2 and the power tool 1 are removably connected to each other. Connecting the rechargeable battery 2 to the power tool 1 also makes it possible to exchange data and information between the rechargeable battery 2 and the power tool 1 in the form of electrical signals. The respective transceivers 19, 25 of the rechargeable battery 2 and the power tool 1 and the respective interconnected communication contacts 13c, 17c are used for transmitting and receiving electrical signals.

[0081] During the use of the rechargeable battery 2 as a power source for the power tool 1, the sensors of the rechargeable battery 2 record the above-mentioned various characteristic operating values. Only some of them can record data. The characteristic operating values recorded by the sensors are stored in the storage unit.

[0082] In addition, the sensors of the rechargeable batteries 2a, 2b also record different characteristic operating values. The recording of the characteristic operating values by the sensors of the rechargeable batteries 2a, 2b can take place during the use of the rechargeable batteries 2a, 2b as a power source for the power tools 1a, 1b and also when the rechargeable batteries 2a, 2b are not used as a power source for the power tools 1a, 1b. In addition, the sensors of the rechargeable batteries 2a, 2b can also record characteristic operating values when the rechargeable batteries 2a, 2b are connected to the charging devices 22a, 22b. It can also be that only some of them record data. The characteristic operating values recorded by the sensors are stored in the storage unit 18.

[0083] At regular or irregular time intervals, the power tools 1a, 1b transmit the characteristic operating values recorded by the sensors 40 of the power tools 1a, 1b to the respective connected rechargeable batteries 2a, 2b by means of the transceivers 11, 19 and the communication contacts 13a, 17c. The characteristic operating values of the power tools 1a, 1b received by the rechargeable batteries 2a, 2b are stored in the storage unit 18 of the rechargeable batteries 2a, 2b.

[0084] As indicated in Figure 5 The rechargeable batteries 2a, 2b can be removed from the respective power tools 1a, 1b and can be removably connected to the charging devices 22a, 22b. The energy storage cells 16 of the rechargeable batteries 2a, 2b can be charged with electrical energy by means of the charging devices 22a, 22b.

[0085] In this exemplary embodiment, the first rechargeable battery 2a and the second rechargeable battery 2b are instructed to be simultaneously removed from their respective power tools 1a and 1b and simultaneously connected to their respective charging devices 22a and 22b. However, it is also possible that the rechargeable batteries 2a and 2b are not simultaneously removed from their power tools 1a and 1b and not simultaneously connected to their charging devices 22a and 22b. The removal of each rechargeable battery 2a and 2b from its power tool 1a and 1b and the connection of each rechargeable battery 2a and 2b to its corresponding charging device 22a and 22b can be performed separately for each rechargeable battery 2a and 2b, resulting in all rechargeable batteries 2a and 2b being removed from their power tools 1a and 1b and connected to their charging devices 22a and 22b within a specific time period. This time period can be several hours or several days.

[0086] Alternatively, more than one rechargeable battery 2a, 2b can be repeatedly connected to a single charging device 22a, 22b.

[0087] In addition, rechargeable batteries 2a and 2b can be alternately connected to different charging devices 22a and 22b.

[0088] The corresponding interfaces 17 of the rechargeable batteries 2a and 2b and the charging devices 22a and 22b are removably connected to each other, such that the corresponding communication contacts 17c and 28c of the rechargeable batteries 2a and 2b and the charging devices 22a and 22b are in contact with each other. Connecting the rechargeable batteries 2a and 2b to the charging devices 22a and 22b also allows the exchange of data and information between the rechargeable batteries 2a and 2b and the charging devices 22a and 22b in the form of electrical signals. The corresponding transceivers 19 and 25 of the rechargeable batteries 2a and 2b and the charging devices 22a and 22b are used to transmit and receive electrical signals.

[0089] Before the actual charging process begins, that is, before the electrical energy from the charging devices 22a and 22b reaches the energy storage cells 16 of the rechargeable batteries 2a and 2b, the rechargeable batteries 2a and 2b transmit characteristic operation values ​​stored in the storage unit 18 to the charging devices 22a and 22b via transceivers 19 and 25 and communication contacts 17c and 28c. The characteristic operation values ​​are the characteristic operation values ​​of the power tools 1a and 1b, or the characteristic operation values ​​of the rechargeable batteries 2a and 2b, or both.

[0090] Even if the sensor has recorded more than one characteristic operation value, only a single characteristic operation value can be sent to the charging devices 22a, 22b.

[0091] The charging devices 22a and 22b store the received characteristic operation values ​​in the storage unit 24 of the charging devices 22a and 22b.

[0092] When the charging device 22a, 22b is connected to the data storage and computing device 29, the characteristic operating values are transmitted to the data storage and computing device 29. Once the corresponding charging device 22a, 22b is connected to the data storage and computing device 29, each charging device 22a, 22b transmits the received characteristic operating values to the data storage and computing device 29.

[0093] The threshold values of the corresponding characteristic operating values recorded by the sensors of the rechargeable battery 2a, 2b are stored in the data storage and computing device 29.

[0094] Furthermore, the individual adjustment parameters for the plurality of different power tools 1a, 1b and rechargeable batteries 2a, 2b as well as the full set of adjustment parameters are stored in the data storage and computing device 29.

[0095] The collected characteristic operating values are compared with the respective threshold values according to their respective categories in the data storage and computing device.

[0096] If at least one characteristic operating value of the first category transmitted by the first charging device 22a, 22b corresponds to the corresponding threshold value and at least one characteristic operating value of the second category transmitted by the first charging device 22a corresponds to the corresponding threshold value, a new adjustment parameter is transmitted from the data storage and computing device 29 to the corresponding charging device 22a, 22b. Instead of a single adjustment parameter, a plurality of adjustment parameters or the full set of adjustment parameters for the rechargeable battery 2a, 2b or the power tool 1a, 1b can likewise be transmitted.

[0097] The new adjustment parameter is then transmitted from the charging device 22a, 22b to the respective connected rechargeable battery 2a, 2b.

[0098] In the control device 20 of the rechargeable battery 2a, 2b, the received new adjustment parameter is used to replace the corresponding adjustment parameter. This corresponding adjustment parameter can also be referred to as the previous or old adjustment parameter. If a plurality of adjustment parameters or the full set of adjustment parameters has been transmitted, the corresponding adjustment parameters are replaced.

[0099] According to an alternative exemplary embodiment, more than a single new adjustment parameter can also be transmitted from the data storage and computing device 29 to the charging device 22a, 22b if more than one characteristic operating value exceeds the corresponding threshold value. In addition, one or more new adjustment parameters can also be transmitted from the data storage and computing device 29 to the charging device 22a, 22b if one or more recorded characteristic operating values have not exceeded the corresponding threshold value, but the recorded characteristic operating values only correspond to these threshold values.

[0100] If the charging device 22a, 22b has sent a new adjustment parameter to the rechargeable battery 2a, 2b and this new adjustment parameter has replaced the previously existing corresponding adjustment parameter, it is considered to start the actual charging process with the new adjustment parameter and the still existing adjustment parameter.

[0101] If during the comparison of the received characteristic operating value with the corresponding threshold value it appears that neither the threshold value is exceeded nor reached, no new adjustment parameter is sent from the data storage and computing device 29 to the charging device 22a, 22b and finally to the rechargeable battery 2a, 2b. As a result, it is considered to start the charging process with the still existing adjustment parameter.

[0102] If one or more adjustment parameters for the power tool 1a, 1b are sent from the data storage and computing device, these adjustment parameters are sent from the charging device 22a, 22b to the corresponding connected rechargeable battery 2a, 2b and stored in the rechargeable battery 2a, 2b. After the rechargeable battery 2a, 2b has been disconnected from the charging device 22a, 22b and reconnected to the corresponding power tool 1a, 1b, the adjustment parameter (or the adjustment parameters) is sent from the rechargeable battery 2a, 2b to the power tool 1a, 1b. These new adjustment parameters are used to replace the corresponding existing adjustment parameters in the power tool 1a, 1b.
