Abstract
A method detects electrical fault states of at least one removable battery pack and/or an electrical device, in particular a charging device, a diagnostic device or an electrical consumer, that can be connected to the at least one removable battery pack, using a first monitoring unit integrated in the at least one removable battery pack and a further monitoring unit integrated in the electrical device. The first monitoring unit and the further monitoring unit each count the faulty charging or discharging processes.
Claims12
A method for detecting electrical fault states of at least one removable battery pack and/or an electrical device that can be connected to the at least one removable battery pack, comprising:
- counting faulty charging or discharging processes using a first monitoring unit integrated in the at least one removable battery pack;
- and
- counting the faulty charging or discharging processes using a second monitoring unit integrated in the electrical device.
hod according to claim 5, further comprising:
- storing the counted charging or discharging processes and/or the calculated reliability values in chronological order using the first and the second monitoring unit.
The method according to claim 7, further comprising:
- assigning a higher weighting to more recent counted charging or discharging processes than older counted charging or discharging processes.
A system comprising:
- at least one removable battery pack including a first monitoring unit and a first electromechanical interface having a first plurality of electrical contacts;
- and
- an electrical device including a second monitoring unit and a second electromechanical interface having a second plurality of electrical contacts,
- wherein in each of the first and second plurality of electrical contacts (i) a first electrical contact is configured as an energy supply contact that can be supplied with a first reference potential, (ii) a second electrical contact is configured as another energy supply contact that can be supplied with a second reference potential, and (iii) a third electrical contact is configured as a signal or data contact configured to exchange data between the first and the second monitoring units,
- wherein the first and the second monitoring units are configured to detect electrical fault states of the at least one removable battery pack and/or the electrical device,
- wherein the first monitoring unit is configured to count faulty charging or discharging processes of the at least one removable battery pack and/or the electrical device, and
- wherein the second monitoring unit is configured to count faulty charging or discharging processes of the at least one removable battery pack and/or the electrical device.
