Abstract

An electrical device having a transport safety system that prevents unwanted discharge of the battery during transport. The electrical device has a battery connected to the electrical device, a charging device configured to be connected to the electrical device or to the battery, and an electrical discharge protection circuit associated with the battery or the electrical device to prevent discharge of the battery during transport. The electrical discharge protection circuit is adapted to be activated when connected to the charging device by engaging a button actuation on the electrical device, and is adapted to be deactivated by charging the battery. The discharge protection circuit is configured so that a wanted or unwanted actuation of the button when the discharge protection circuit is activated does not lead to activation of electrical components of the electrical device.

Claims

1. A method for forming a transport safety system in an electrical device operated by a battery, for preventing discharge of the battery during transport, comprising the following steps:

providing an electrical discharge protection circuit for the battery or the electrical device,

activating the discharge protection circuit by pressing a button actuation provided on the device, and

deactivating the discharge protection circuit by charging the battery, wherein a wanted or unwanted actuation of the button when the discharge protection circuit is activated does not lead to activation of electrical components of the device.

2. An electrical device having a transport safety system, comprising:

a battery connected to the electrical device,

a charging device configured to be connected to the electrical device or to the battery, and

an electrical discharge protection circuit associated with the battery or the electrical device to prevent discharge of the battery during transport,

wherein the electrical discharge protection circuit is adapted to be activated when connected to the charging device by engaging a button actuation on the electrical device, and is adapted to be deactivated by charging the battery,

wherein the discharge protection circuit is configured so that a wanted or unwanted actuation of the button when the discharge protection circuit is activated does not lead to activation of electrical components of the electrical device.

3. The electrical device according to claim 2, wherein at least one of the electrical device and the charging device has a microcontroller that deactivates the discharge protection circuit when a charging current is detected.

4. The electrical device according to claim 2, wherein the electrical device has an electric motor and wherein the discharge protection circuit comprises a switch which interrupts the voltage supply to an electric motor of the device.

5. The electrical device according to claim 2, wherein the discharge protection circuit is adapted to be selectively activated.

6. An electrical device having a transport safety system, comprising;

a battery connected to the electrical device,

a charging device for the electrical device, and

an electrical discharge protection circuit associated with the electrical device or the battery to prevent discharge of the battery during transport,

wherein the discharge protection circuit is activated by a mechanical switch which interrupts a voltage supply to the electrical device,

wherein the charging device has an active part for actuating the switch, and

wherein the electrical discharge protection circuit is adapted to be deactivated by charging the battery.

7. The combination according to claim 6, wherein the electrical discharge protection circuit is adapted to be selectively activated.
