[0214] Furthermore, the engine control switch 5 is a isolating switch 5'.

[0215] In addition, the activation circuit 6 has an electrical state device 8. The activation circuit 6 is designed to transfer the state device 8 from an electrical non-activation state to an electrical activation state if the at least, in particular precisely, one, in particular low-side, battery pack 101, 101a is fully connected and the engine control switch 5 is not actuated, and in particular not otherwise, in particular to transfer, in particular transferring, from the activation state to the non-activation state.

In alternative embodiments, the non-activation offset time constant and / or the activation offset time constant can be realized or enabled without the resistor R, in particular due to a natural insulation resistance, in particular of the capacitor 9'.

[0219] In addition, the state device 8 is designed, in particular generating, in the activation state, in particular electrical charge of the charge storage device 9 in the charged state, by changing the engine control switch 5 from non-actuated to actuated, as shown in Figs. 14 to 17, or to enable generation of an electrical state signal ZS, in particular a state signal pulse ZSI, in particular for triggering the transfer of the engine control device 4 from the inactive state to the active state.

[0220] Furthermore, the activation circuit 6 has an electrical triggering device 10. The triggering device 10 is designed to generate or enable the generation of an electrical triggering signal AS, in particular a triggering signal pulse ASI, for enabling the switching of the engine control device 4 from the inactive state to the active state, if the at least, in particular exactly, one, in particular low-side, battery pack 101, 101a, 101b is connected, in particular completely, in particular if a high-side battery pack 101b is connected, and the engine control switch 5 is not actuated and, based thereon, the engine control switch 5 changes from not actuated to actuated, in particular by the status device 8 in the activation state and the change of the engine control switch 5 from not actuated to actuated, in particular by the status signal ZS, in particular generating or enabling.

[0221] In detail, the triggering device 10 is an electronic trigger switch 11, in particular a transistor 1 T. The trigger switch 11 is designed, in particular offset, to shift from an electrically non-conductive state to an electrically conductive state for generating or releasing.

[0222] In addition, the activation circuit 6 has an electronic supply switch 12, in particular a transistor 12'. The supply switch 12 is designed to switch from an electrically non-conductive state to an electrically conductive state to enable the supply of the control power KL to the engine control device 4, in particular to pass the control power KL to the engine control device 4, if the at least one battery pack 101, 101a, 101b is fully connected, in particular if the high-side battery pack 101b is connected, and the engine control switch 5 is not actuated and, based thereon, the engine control switch 5 changes from non-actuated to actuated, in particular by the trigger signal AS, in particular generated by the high-side battery pack 101b, in particular offset.

[0223] In detail, the processing device 1 has at least one voltage limiter 13, 14, in particular a Zener diode 13', 14', for limiting, in particular limiting, a voltage at a gate G1 T, G12' of the transistor 1 T, 12' below a breakdown voltage DSP of the transistor 1 T, 12'.

[0224] Furthermore, the at least one battery pack interface 3, 3a, 3b is designed to be connected to the at least one battery pack 101, 101a, 101b with a nominal voltage NSP of at least 18 V, in particular at least 24 V, in particular at least 28 V, in particular 36 V. In Fig. 14 to 17, the processing device 1 is a wood cutter T. In alternative embodiments, the processing device can be a hedge cutter, or a hedge trimmer, or a grass shear, or a grass trimmer, or a multi-tool, or a pole pruner, or a saw, or a brush cutter, or a blower, or a leaf blower, or a branch cutter, or a power cutter, or a sweeper, or a roller brush, or a lawn mower, or a scarifier, or a shredder, or a motor hoe, or a stone cutter, or a high-pressure cleaner, or a cleaning device, or a suction device, or a spraying and / or spraying device.

[0225] In other words, particularly as shown in Fig. 14 and 15:

[0226] If both battery packs 101a, 101b are connected or contacted, the voltage Va+Vb is present at the processing device 1, and the processing device 1 can be switched on via the motor control switch 5, in particular the drive motor 2 can start. If or when only the battery pack 101a is connected or present, the voltage Va is present at the processing device 1 via the rectifier diode 7b, which may be sufficient to switch on or operate the processing device 1. The same applies if only the battery pack 101b is present. Then the voltage Vb is present via the rectifier diode 7a, which may be sufficient to operate the processing device 1. In this case, switching on the processing device 1 via the motor control switch 5 should be avoided or prevented.Likewise, it should be prevented that the processing device 1 can be switched on if the battery pack 101b is not present and Va is applied to the processing device 1 via the rectifier diode 7b. Furthermore, it should be prevented that the processing device 1 is switched on if the battery packs 101a, 101b are connected while the motor control switch 5 is already actuated. The processing device 1 may only be switched on if all battery packs 101a, 101b are present and then the motor control switch 5 is actuated. This function is achieved by the activation circuit 6 in Fig. 14.

[0227] In detail, when the battery pack 101a is present, the capacitor 9' is charged to the voltage Va. By actuating the motor control switch 5, the charge of the capacitor 9' is conducted via a resistor R' to the gate G1 T of the NMOS transistor 1 T. The Zener diode 13' limits the voltage at the gate G1 T to permissible values. The transistor 1 T is switched on or turned on as long as the motor control switch 5 is actuated and the charge on the capacitor 9' is sufficient. When the battery pack 101b is present, a current flows through resistors R" and R"'. The voltage drop across resistor R"—limited by Zener diode 14'—transposes or causes PMOS transistor 12 to conduct. The total operating voltage (sum of Va and Vb) is then applied to terminal VO, in particular to supply the motor control device 4 with the control power KL. The current flow is limited here by a resistor R"".

[0228] In particular, the supply of the drive motor 2 with the drive power AL is controlled by means of a circuit breaker LS.

[0229] Additionally or alternatively, the control depends on the actuation of the engine control switch 5 by means of an engine control switch evaluation.

[0230] The activation circuit 6 can also be used in a similar way to prevent the drive motor 2 from starting in the processing device 1 with only one battery pack 101 if the battery pack 101 is connected while the motor control switch 5 is already actuated. The corresponding embodiment or variant is shown in Figs. 16 and 17.

[0231] Furthermore, the drive power AL is at least 10 watts (W), in particular at least 100 W, in particular at least 1 kW (kilowatt), in particular at least 2 kW, and / or at most 10 kW, in particular at most 5 kW, in particular 3 kW.

[0232] Additionally or alternatively, a maximum, in particular electrical, energy content, in particular nominal energy content, of the battery pack 101, 101a, 101b is at least 50 Wh (watt hours), in particular at least 100 Wh, in particular at least 200 Wh, and / or at most 4000 Wh, in particular at most 2000 Wh, in particular at most 1000 Wh, in particular at most 500 Wh, in particular 337 Wh.

[0233] As the embodiments shown and explained above make clear, the invention provides the advantageous hand-held processing device which has improved properties.
